Product overview
Xperia™ SP HSPA – Experience the brilliance of
Sony inside and out
High definition entertainment in a premium design.
Xperia™ SP has the looks of a true design connoisseur’s smartphone. The super-sharp HD screen covers
almost the entire front. It stays spectacularly black when off, turns vibrantly colourful when on. This phone
runs on the latest Android platform, and it’s got all you need for moment-catching too. The 8 megapixel
camera goes from sleep to snap in less than a second. Feel a still’s not enough? Shoot scenes and
scenery in beautiful HD video. You’ll get a perfect result every time. It’s a wrap? Then easily view it all on
your TV via one-touch sharing.
Beauty well crafted
How would you define quality? To add that extra touch of you-style, try the customisable illuminations.
They notify you of events, Facebook updates and more. And give that extra oomph to your music and
pictures.
Closer to reality
Lost in the woods, wolfpack closing in. On the pitch, dodging that sliding tackle. Xperia™ SP’s 4.6” HD
screen is so vivid you feel you’re in the middle of it all - no matter what you’re viewing. The Reality Display
is powered by Mobile BRAVIA® Engine 2. That means razor sharp images, vibrant colours and the
enhanced contrast you recognize from Sony TV’s.
Easy connectivity with one-touch functions
The NFC-enabled smartphone lets you share pictures with other phones in a single touch. Or you can
touch your Xperia™ SP to a Bluetooth™ speaker and listen to music saved on the phone.
Share your phone screen on a TV
You can play your videos on a big screen by connecting a standard HDMI cable to your HDTV using an
MHL adapter* or a compatible TV Dock* accessory. If you prefer to go wireless, you can use the Screen
Mirroring** feature to share content from your phone via the TV. With the touch of a button, you can watch
your selected photo pop up on the TV screen or listen to the current music track play on the TV’s
speakers.
Snap and shoot – anytime, any light
Getting dark? Don’t let that stop you. The Exmor RS™ for mobile sensor gives you radiant pictures even in
low light. No need to worry about getting the camera settings right either. Superior Auto mode helps you
to that perfect picture without further ado - noise reduction is automatically activated when needed.
Music the way you want it
Ragga, grime or boy bands? With the “WALKMAN” app, you customise your music experience as you
please. Create your own playlists and listen in Soul shaking clarity with Clear Audio+*** and xLoud
loudness enhancement. Can’t get enough? Go further into Music Unlimited and choose from millions of
songs. When you’ve found the right track, crank it up and get the sound just right with graphic equalisers.
Or connect to wireless speakers with just a touch and use your smartphone as the ultimate DJ deck.

White paper | Xperia™ SP HSPA
Memory in Android™ phones
To use Android phones efficiently, users should be aware of the different types of phone memory. This
knowledge is important in order to understand, for example, where music, photos and videos are saved;
how many apps can be downloaded from Google Play™; and how photos can be copied to a PC.
The below information is also of interest to developers who wants to make their programs able to make
the best possible use of the resources in the phone.
Generally, all Android phones share the same basic memory setup. What differs is how much memory is
available to you via the different types of memory, and whether your phone uses an external SD card or an
internal memory chip. Any information specific to the particular phone model described in this White
Paper is noted as such.
Types of memory
The types of memory described below are consistent with the terminology used in Sony mobile phone
menus and in other content relating to 2013 Xperia™ phones:
1. Dynamic Memory (also known as RAM) is used by applications that run when the phone is turned on.
The amount of Dynamic Memory influences how many applications and operating system services can
run at the same time. In Android™, the operating system automatically closes applications and
services that are not being used.
However, such automatic functionality has limits. For example, if a lower amount of free RAM is
available to applications after a new release of the operating system (due to increased capabilities in
the system), phone speed will eventually be impacted (this is the main reason that a certain device
cannot be indefinitely upgraded to newer releases of Android™).
If you experience problems with RAM, for example, if the phone runs slower than usual or if the Home
application restarts frequently when you leave an application, you should minimize the use of apps that
run all the time. Such apps could include, for example, applications that frequently download social
service updates. You could also consider using a static wallpaper instead of a live wallpaper.
To see which apps and services are currently active, go to Settings > Applications > Running
Services. You should have at least 50 MB, and ideally 100 MB or more, of free RAM to avoid
slowdowns and application restarts.
You should also be aware that if you update the phone to a later Android release, the load on the builtin Dynamic Memory will increase due to the addition of more features, as mentioned above. As a
result, the phone may run slower after an update.
2. System Memory (also known as “System partition” or “/system”) is used for the Android OS and for
most applications that are pre-loaded from the factory. This type of memory is normally locked, and
can only be changed through a firmware upgrade. There is usually some free space available in this
section of memory. However, since it is locked, you cannot save apps, photos or any other content to
this memory. System Memory is reserved for future firmware upgrades, which almost always need
more memory than the original firmware. You cannot see or influence the use of this memory.
3. Internal Storage is memory used as” working” memory. It can be compared to the C: drive on a PC or
to the startup disk on a Mac.
This memory is used to store all application downloaded from Google Play Store™ (and other sources)
and their settings and data (such as emails, messages, calendar events and the like). All applications
have an allocated area which no other applications can access and where the application data can be
16
January 2014
White paper | Xperia™ SP HSPA
stored.
Some games also stores content such as games music and level information outside their own
designated area; and generally, any application can choose to save their data in locations of their own
choosing (outside the protected application settings areas). Generally, such content is not deleted
when an application is uninstalled but must be removed manually, by connecting the phone to a
computer with a USB cable, or by the use of a file manager application.
Internal Storage is also used for all user content added, for example, as a result of the user taking
photos with the camera, downloading media files, and performing file transfers. Typical user content
includes:
• photos
• movies
• music
• downloaded documents (as email attachments, for example)
Internal Storage will tend to fill up as a result of normal usage: use of applications saving their data,
downloading and installing new applications, downloading free or bought content and taking pictures
and movies. Therefore, the larger this memory is from the start, the more applications you can
download and use, and the more pictures and movies you can take.
If the Internal Storage starts to get full, the phone slows down, and in some cases it might no longer be
possible to install more apps. You should always ensure that you have at least 100 MB of free Phone
Memory. If not, you should consider removing some apps that you seldom use, or move content you
do not frequently access to safe storage.
You can see approximately how much Internal Storage is free in Settings > Storage >Internal
Storage. You can also view more detail about how much memory is used by applications in Settings >
Applications > Manage Applications.
Please note that in Sony Mobile 2013 products, “Internal Storage” is now the union of what was
previously known as “Phone Memory” (for applications and their data. “/data”) and “Internal Storage”
(for user’s content, “/sdcard”). The reason for this change is to make the use of available memory more
flexible, and also to enable the optional encryption of user’s content.
Memory card slot
In some products you may find both a large internal memory and a memory card reader slot. However, on
the current Android platform, the card reader slot does not work in the same manner in a phone with large
internal memory, as in a phone with ONLY a memory card slot.
Generally, since most applications expect only a single location of storage, such applications will not
generally allow you to SAVE anything to the card (i.e. they will lack an option to choose storage location);
however, some applications (for instance, the Sony Mobile “Camera” application) may actually allow you
to do so. Other, for example backup applications such as the Sony Mobile “Memory” application, will by
definition be configured to copy content from the Internal Storage to the external SD card.
On the other hand, when it comes to READING from an external SD Card, you will be able access content
(videos, photos, music) on a memory card inserted in this slot without any special considerations since the
Android system searches all available memory for content. Therefore, such products may be regarded as
supporting a fourth type of memory, called “External Card”.
17
January 2014
White paper | Xperia™ SP HSPA
4. SD Card (known as “/ext_card” from a programmer’s point of view, or by other names in other Android
products) is the name for the removable SD memory card in all 2013 Sony Mobile products. As
described above, this External Card memory is generally more limited in that any application can READ
from it, but many applications cannot SAVE to this card. Only a few applications, including back-up
applications and file manger applications, has the capability to save to this card.
Backing up data to different memory types
Generally, you should not save photos, videos and other personal content solely on the internal memory
of a phone. If something should happen with the hardware, or if the phone is lost or stolen, the data stored
on the phone’s internal memory is gone forever.
In a phone where an SD card reader is the main memory, it is relatively easy to take the card out and copy
all content to a PC or Mac, or to an entertainment device with a memory card slot. In a product featuring
Internal Storage as the main memory, it is not possible to physically remove the memory. Instead, any
critical or high-value content must either be copied to an external SD card by a special backup
application, transferred to remote storage over a network (mobile or Wi-Fi), or to a computer via a USB
cable.
To facilitate the transfer of data via a cable, the Xperia™ SP supports the Microsoft standard, Media
Transfer Protocol (MTP), which makes it possible to easily transfer content back and forth between your
phone and a Windows PC. For Apple Mac computers, a special application, BridgeforMac, is available
offering built-in support for MTP; this application can be downloaded from the Xperia™ SP Support page.
Note that you do not need to back up or make a copy of applications that you have downloaded from
Google Play™. They can normally be downloaded again if, once you have set up your Google account to
work in a new phone phone (or a phone where the memory has been completely erased).
Note 1:
As noted above, some Android phones, including Sony Mobile devices from 2012, and Sony Ericsson
devices from 2011 and earlier, do not use a single “Internal Storage” for both applications (and their data)
and user content. Instead, these devices use either an external SD card for user content, or a
corresponding area of internal memory to reproduce the functionality of an SD card. In such devices, there
is a fixed limit between the application area (“/data”) and the user content area (“/sdcard); with the result
that user content can be filled, stopping the taking of new pictures for example, while there is still
considerable free space in the application area; or vice versa, stopping the download and installation of
new applications even though there is free memory in the content area.
Note 2:
Some devices with an integrated storage have abandoned the distinction between the application area
and the content area when it comes to Factory Data Reset. As a result, there is no choice to do Factory
Data Reset and preserve content; in such devices, all content is mandatorily and completely deleted from
the device when a reset is performed.
In contrast, Sony Mobile has done the integration in a manner which makes it possible to preserve user
content in this situation; therefore, when performing a Factory Data Reset, the default will still be to only
remove applications and their data, and an option box must be checked if also all content is to be
removed (as might be desirable when selling the device second-hand, for instance).
Note 3:
For a developer, it is important to note that from a programmer’s point of view, the location names used to
refer to the different memory areas described in Note 1 are still valid; i.e., the area used for application (/
data) is still present, as is the area used for content (/sdcard).

In reality, “sdcard” is a so-called symbolic link to “/data/media”, but from inside an Android application, “/
sdcard” can still be used (for instance, use “sdcard/DCIM/100Android” to find all camera images).
Continuing to use /sdcard to access the content area ensures compatibility across different products and
Android releases in this regard.

Product overview
Xperia™ SP LTE – Experience the brilliance of Sony
inside and out
High definition entertainment in a premium design.
Xperia™ SP has the looks of a true design connoisseur’s smartphone. The super-sharp HD screen covers
almost the entire front. It stays spectacularly black when off, turns vibrantly colourful when on. This phone
runs on the latest Android platform, and it’s got all you need for moment-catching too. The 8 megapixel
camera goes from sleep to snap in less than a second. Feel a still’s not enough? Shoot scenes and
scenery in beautiful HD video. You’ll get a perfect result every time. It’s a wrap? Then easily view it all on
your TV via one-touch sharing.
Beauty well crafted
How would you define quality? To add that extra touch of you-style, try the customisable illuminations.
They notify you of events, Facebook updates and more. And give that extra oomph to your music and
pictures.
Closer to reality
Lost in the woods, wolfpack closing in. On the pitch, dodging that sliding tackle. Xperia™ SP’s 4.6” HD
screen is so vivid you feel you’re in the middle of it all - no matter what you’re viewing. The Reality Display
is powered by Mobile BRAVIA® Engine 2. That means razor sharp images, vibrant colours and the
enhanced contrast you recognize from Sony TV’s.
Easy connectivity with one-touch functions
The NFC-enabled smartphone lets you share pictures with other phones in a single touch. Or you can
touch your Xperia™ SP to a Bluetooth™ speaker and listen to music saved on the phone.
Share your phone screen on a TV
You can play your videos on a big screen by connecting a standard HDMI cable to your HDTV using an
MHL adapter* or a compatible TV Dock* accessory. If you prefer to go wireless, you can use the Screen
Mirroring** feature to share content from your phone via the TV. With the touch of a button, you can watch
your selected photo pop up on the TV screen or listen to the current music track play on the TV’s
speakers.
Snap and shoot – anytime, any light
Getting dark? Don’t let that stop you. The Exmor RS™ for mobile sensor gives you radiant pictures even in
low light. No need to worry about getting the camera settings right either. Superior Auto mode helps you
to that perfect picture without further ado - noise reduction is automatically activated when needed.
Music the way you want it
Ragga, grime or boy bands? With the “WALKMAN” app, you customise your music experience as you
please. Create your own playlists and listen in Soul shaking clarity with Clear Audio+*** and xLoud
loudness enhancement. Can’t get enough? Go further into Music Unlimited and choose from millions of
songs. When you’ve found the right track, crank it up and get the sound just right with graphic equalisers.
Or connect to wireless speakers with just a touch and use your smartphone as the ultimate DJ deck.

Memory in Android™ phones
To use Android phones efficiently, users should be aware of the different types of phone memory. This
knowledge is important in order to understand, for example, where music, photos and videos are saved;
how many apps can be downloaded from Google Play™; and how photos can be copied to a PC.
The below information is also of interest to developers who wants to make their programs able to make
the best possible use of the resources in the phone.
Generally, all Android phones share the same basic memory setup. What differs is how much memory is
available to you via the different types of memory, and whether your phone uses an external SD card or an
internal memory chip. Any information specific to the particular phone model described in this White
Paper is noted as such.
Types of memory
The types of memory described below are consistent with the terminology used in Sony mobile phone
menus and in other content relating to 2013 Xperia™ phones:
1. Dynamic Memory (also known as RAM) is used by applications that run when the phone is turned on.
The amount of Dynamic Memory influences how many applications and operating system services can
run at the same time. In Android™, the operating system automatically closes applications and
services that are not being used.
However, such automatic functionality has limits. For example, if a lower amount of free RAM is
available to applications after a new release of the operating system (due to increased capabilities in
the system), phone speed will eventually be impacted (this is the main reason that a certain device
cannot be indefinitely upgraded to newer releases of Android™).
If you experience problems with RAM, for example, if the phone runs slower than usual or if the Home
application restarts frequently when you leave an application, you should minimize the use of apps that
run all the time. Such apps could include, for example, applications that frequently download social
service updates. You could also consider using a static wallpaper instead of a live wallpaper.
To see which apps and services are currently active, go to Settings > Applications > Running
Services. You should have at least 50 MB, and ideally 100 MB or more, of free RAM to avoid
slowdowns and application restarts.
You should also be aware that if you update the phone to a later Android release, the load on the builtin Dynamic Memory will increase due to the addition of more features, as mentioned above. As a
result, the phone may run slower after an update.
2. System Memory (also known as “System partition” or “/system”) is used for the Android OS and for
most applications that are pre-loaded from the factory. This type of memory is normally locked, and
can only be changed through a firmware upgrade. There is usually some free space available in this
section of memory. However, since it is locked, you cannot save apps, photos or any other content to
this memory. System Memory is reserved for future firmware upgrades, which almost always need
more memory than the original firmware. You cannot see or influence the use of this memory.
3. Internal Storage is memory used as” working” memory. It can be compared to the C: drive on a PC or
to the startup disk on a Mac.
This memory is used to store all application downloaded from Google Play Store™ (and other sources)
and their settings and data (such as emails, messages, calendar events and the like). All applications
have an allocated area which no other applications can access and where the application data can be
16
January 2014
White paper | Xperia™ SP LTE
stored.
Some games also stores content such as games music and level information outside their own
designated area; and generally, any application can choose to save their data in locations of their own
choosing (outside the protected application settings areas). Generally, such content is not deleted
when an application is uninstalled but must be removed manually, by connecting the phone to a
computer with a USB cable, or by the use of a file manager application.
Internal Storage is also used for all user content added, for example, as a result of the user taking
photos with the camera, downloading media files, and performing file transfers. Typical user content
includes:
• photos
• movies
• music
• downloaded documents (as email attachments, for example)
Internal Storage will tend to fill up as a result of normal usage: use of applications saving their data,
downloading and installing new applications, downloading free or bought content and taking pictures
and movies. Therefore, the larger this memory is from the start, the more applications you can
download and use, and the more pictures and movies you can take.
If the Internal Storage starts to get full, the phone slows down, and in some cases it might no longer be
possible to install more apps. You should always ensure that you have at least 100 MB of free Phone
Memory. If not, you should consider removing some apps that you seldom use, or move content you
do not frequently access to safe storage.
You can see approximately how much Internal Storage is free in Settings > Storage >Internal
Storage. You can also view more detail about how much memory is used by applications in Settings >
Applications > Manage Applications.
Please note that in Sony Mobile 2013 products, “Internal Storage” is now the union of what was
previously known as “Phone Memory” (for applications and their data. “/data”) and “Internal Storage”
(for user’s content, “/sdcard”). The reason for this change is to make the use of available memory more
flexible, and also to enable the optional encryption of user’s content.
Memory card slot
In some products you may find both a large internal memory and a memory card reader slot. However, on
the current Android platform, the card reader slot does not work in the same manner in a phone with large
internal memory, as in a phone with ONLY a memory card slot.
Generally, since most applications expect only a single location of storage, such applications will not
generally allow you to SAVE anything to the card (i.e. they will lack an option to choose storage location);
however, some applications (for instance, the Sony Mobile “Camera” application) may actually allow you
to do so. Other, for example backup applications such as the Sony Mobile “Memory” application, will by
definition be configured to copy content from the Internal Storage to the external SD card.
On the other hand, when it comes to READING from an external SD Card, you will be able access content
(videos, photos, music) on a memory card inserted in this slot without any special considerations since the
Android system searches all available memory for content. Therefore, such products may be regarded as
supporting a fourth type of memory, called “External Card”.
17
January 2014
White paper | Xperia™ SP LTE
4. SD Card (known as “/ext_card” from a programmer’s point of view, or by other names in other Android
products) is the name for the removable SD memory card in all 2013 Sony Mobile products. As
described above, this External Card memory is generally more limited in that any application can READ
from it, but many applications cannot SAVE to this card. Only a few applications, including back-up
applications and file manger applications, has the capability to save to this card.
Backing up data to different memory types
Generally, you should not save photos, videos and other personal content solely on the internal memory
of a phone. If something should happen with the hardware, or if the phone is lost or stolen, the data stored
on the phone’s internal memory is gone forever.
In a phone where an SD card reader is the main memory, it is relatively easy to take the card out and copy
all content to a PC or Mac, or to an entertainment device with a memory card slot. In a product featuring
Internal Storage as the main memory, it is not possible to physically remove the memory. Instead, any
critical or high-value content must either be copied to an external SD card by a special backup
application, transferred to remote storage over a network (mobile or Wi-Fi), or to a computer via a USB
cable.
To facilitate the transfer of data via a cable, the Xperia™ SP supports the Microsoft standard, Media
Transfer Protocol (MTP), which makes it possible to easily transfer content back and forth between your
phone and a Windows PC. For Apple Mac computers, a special application, BridgeforMac, is available
offering built-in support for MTP; this application can be downloaded from the Xperia™ SP Support page.
Note that you do not need to back up or make a copy of applications that you have downloaded from
Google Play™. They can normally be downloaded again if, once you have set up your Google account to
work in a new phone phone (or a phone where the memory has been completely erased).
Note 1:
As noted above, some Android phones, including Sony Mobile devices from 2012, and Sony Ericsson
devices from 2011 and earlier, do not use a single “Internal Storage” for both applications (and their data)
and user content. Instead, these devices use either an external SD card for user content, or a
corresponding area of internal memory to reproduce the functionality of an SD card. In such devices, there
is a fixed limit between the application area (“/data”) and the user content area (“/sdcard); with the result
that user content can be filled, stopping the taking of new pictures for example, while there is still
considerable free space in the application area; or vice versa, stopping the download and installation of
new applications even though there is free memory in the content area.
Note 2:
Some devices with an integrated storage have abandoned the distinction between the application area
and the content area when it comes to Factory Data Reset. As a result, there is no choice to do Factory
Data Reset and preserve content; in such devices, all content is mandatorily and completely deleted from
the device when a reset is performed.
In contrast, Sony Mobile has done the integration in a manner which makes it possible to preserve user
content in this situation; therefore, when performing a Factory Data Reset, the default will still be to only
remove applications and their data, and an option box must be checked if also all content is to be
removed (as might be desirable when selling the device second-hand, for instance).
Note 3:
For a developer, it is important to note that from a programmer’s point of view, the location names used to
refer to the different memory areas described in Note 1 are still valid; i.e., the area used for application (/
data) is still present, as is the area used for content (/sdcard).

In reality, “sdcard” is a so-called symbolic link to “/data/media”, but from inside an Android application, “/
sdcard” can still be used (for instance, use “sdcard/DCIM/100Android” to find all camera images).
Continuing to use /sdcard to access the content area ensures compatibility across different products and
Android releases in this regard.

Product overview
Xperia™ SP – Experience the brilliance of Sony
inside and out
High definition entertainment in a premium design.
Xperia™ SP has the looks of a true design connoisseur’s smartphone. The super-sharp HD screen covers
almost the entire front. It stays spectacularly black when off, turns vibrantly colourful when on. This phone
runs on the latest Android platform, and it’s got all you need for moment-catching too. The 8 megapixel
camera goes from sleep to snap in less than a second. Feel a still’s not enough? Shoot scenes and
scenery in beautiful HD video. You’ll get a perfect result every time. It’s a wrap? Then easily view it all on
your TV via one-touch sharing.
Beauty well crafted
How would you define quality? To add that extra touch of you-style, try the customisable illuminations.
They notify you of events, Facebook updates and more. And give that extra oomph to your music and
pictures.
Closer to reality
Lost in the woods, wolfpack closing in. On the pitch, dodging that sliding tackle. Xperia™ SP’s 4.6” HD
screen is so vivid you feel you’re in the middle of it all - no matter what you’re viewing. The Reality Display
is powered by Mobile BRAVIA® Engine 2. That means razor sharp images, vibrant colours and the
enhanced contrast you recognize from Sony TV’s.
Easy connectivity with one-touch functions
The NFC-enabled smartphone lets you share pictures with other phones in a single touch. Or you can
touch your Xperia™ SP to a Bluetooth™ speaker and listen to music saved on the phone.
Share your phone screen on a TV
You can play your videos on a big screen by connecting a standard HDMI cable to your HDTV using an
MHL adapter* or a compatible TV Dock* accessory. If you prefer to go wireless, you can use the Screen
Mirroring** feature to share content from your phone via the TV. With the touch of a button, you can watch
your selected photo pop up on the TV screen or listen to the current music track play on the TV’s
speakers.
Snap and shoot – anytime, any light
Getting dark? Don’t let that stop you. The Exmor RS™ for mobile sensor gives you radiant pictures even in
low light. No need to worry about getting the camera settings right either. Superior Auto mode helps you
to that perfect picture without further ado - noise reduction is automatically activated when needed.
Music the way you want it
Ragga, grime or boy bands? With the “WALKMAN” app, you customise your music experience as you
please. Create your own playlists and listen in Soul shaking clarity with Clear Audio+*** and xLoud
loudness enhancement. Can’t get enough? Go further into Music Unlimited and choose from millions of
songs. When you’ve found the right track, crank it up and get the sound just right with graphic equalisers.
Or connect to wireless speakers with just a touch and use your smartphone as the ultimate DJ deck.

White paper | Xperia™ SP
Memory in Android™ phones
To use Android phones efficiently, users should be aware of the different types of phone memory. This
knowledge is important in order to understand, for example, where music, photos and videos are saved;
how many apps can be downloaded from Google Play™; and how photos can be copied to a PC.
The below information is also of interest to developers who wants to make their programs able to make
the best possible use of the resources in the phone.
Generally, all Android phones share the same basic memory setup. What differs is how much memory is
available to you via the different types of memory, and whether your phone uses an external SD card or an
internal memory chip. Any information specific to the particular phone model described in this White
Paper is noted as such.
Types of memory
The types of memory described below are consistent with the terminology used in Sony mobile phone
menus and in other content relating to 2013 Xperia™ phones:
1. Dynamic Memory (also known as RAM) is used by applications that run when the phone is turned on.
The amount of Dynamic Memory influences how many applications and operating system services can
run at the same time. In Android™, the operating system automatically closes applications and
services that are not being used.
However, such automatic functionality has limits. For example, if a lower amount of free RAM is
available to applications after a new release of the operating system (due to increased capabilities in
the system), phone speed will eventually be impacted (this is the main reason that a certain device
cannot be indefinitely upgraded to newer releases of Android™).
If you experience problems with RAM, for example, if the phone runs slower than usual or if the Home
application restarts frequently when you leave an application, you should minimize the use of apps that
run all the time. Such apps could include, for example, applications that frequently download social
service updates. You could also consider using a static wallpaper instead of a live wallpaper.
To see which apps and services are currently active, go to Settings > Applications > Running
Services. You should have at least 50 MB, and ideally 100 MB or more, of free RAM to avoid
slowdowns and application restarts.
You should also be aware that if you update the phone to a later Android release, the load on the builtin Dynamic Memory will increase due to the addition of more features, as mentioned above. As a
result, the phone may run slower after an update.
2. System Memory (also known as “System partition” or “/system”) is used for the Android OS and for
most applications that are pre-loaded from the factory. This type of memory is normally locked, and
can only be changed through a firmware upgrade. There is usually some free space available in this
section of memory. However, since it is locked, you cannot save apps, photos or any other content to
this memory. System Memory is reserved for future firmware upgrades, which almost always need
more memory than the original firmware. You cannot see or influence the use of this memory.
3. Internal Storage is memory used as” working” memory. It can be compared to the C: drive on a PC or
to the startup disk on a Mac.
This memory is used to store all application downloaded from Google Play Store™ (and other sources)
and their settings and data (such as emails, messages, calendar events and the like). All applications
have an allocated area which no other applications can access and where the application data can be
16
January 2014
White paper | Xperia™ SP
stored.
Some games also stores content such as games music and level information outside their own
designated area; and generally, any application can choose to save their data in locations of their own
choosing (outside the protected application settings areas). Generally, such content is not deleted
when an application is uninstalled but must be removed manually, by connecting the phone to a
computer with a USB cable, or by the use of a file manager application.
Internal Storage is also used for all user content added, for example, as a result of the user taking
photos with the camera, downloading media files, and performing file transfers. Typical user content
includes:
• photos
• movies
• music
• downloaded documents (as email attachments, for example)
Internal Storage will tend to fill up as a result of normal usage: use of applications saving their data,
downloading and installing new applications, downloading free or bought content and taking pictures
and movies. Therefore, the larger this memory is from the start, the more applications you can
download and use, and the more pictures and movies you can take.
If the Internal Storage starts to get full, the phone slows down, and in some cases it might no longer be
possible to install more apps. You should always ensure that you have at least 100 MB of free Phone
Memory. If not, you should consider removing some apps that you seldom use, or move content you
do not frequently access to safe storage.
You can see approximately how much Internal Storage is free in Settings > Storage >Internal
Storage. You can also view more detail about how much memory is used by applications in Settings >
Applications > Manage Applications.
Please note that in Sony Mobile 2013 products, “Internal Storage” is now the union of what was
previously known as “Phone Memory” (for applications and their data. “/data”) and “Internal Storage”
(for user’s content, “/sdcard”). The reason for this change is to make the use of available memory more
flexible, and also to enable the optional encryption of user’s content.
Memory card slot
In some products you may find both a large internal memory and a memory card reader slot. However, on
the current Android platform, the card reader slot does not work in the same manner in a phone with large
internal memory, as in a phone with ONLY a memory card slot.
Generally, since most applications expect only a single location of storage, such applications will not
generally allow you to SAVE anything to the card (i.e. they will lack an option to choose storage location);
however, some applications (for instance, the Sony Mobile “Camera” application) may actually allow you
to do so. Other, for example backup applications such as the Sony Mobile “Memory” application, will by
definition be configured to copy content from the Internal Storage to the external SD card.
On the other hand, when it comes to READING from an external SD Card, you will be able access content
(videos, photos, music) on a memory card inserted in this slot without any special considerations since the
Android system searches all available memory for content. Therefore, such products may be regarded as
supporting a fourth type of memory, called “External Card”.

4. SD Card (known as “/ext_card” from a programmer’s point of view, or by other names in other Android
products) is the name for the removable SD memory card in all 2013 Sony Mobile products. As
described above, this External Card memory is generally more limited in that any application can READ
from it, but many applications cannot SAVE to this card. Only a few applications, including back-up
applications and file manger applications, has the capability to save to this card.
Backing up data to different memory types
Generally, you should not save photos, videos and other personal content solely on the internal memory
of a phone. If something should happen with the hardware, or if the phone is lost or stolen, the data stored
on the phone’s internal memory is gone forever.
In a phone where an SD card reader is the main memory, it is relatively easy to take the card out and copy
all content to a PC or Mac, or to an entertainment device with a memory card slot. In a product featuring
Internal Storage as the main memory, it is not possible to physically remove the memory. Instead, any
critical or high-value content must either be copied to an external SD card by a special backup
application, transferred to remote storage over a network (mobile or Wi-Fi), or to a computer via a USB
cable.
To facilitate the transfer of data via a cable, the Xperia™ SP supports the Microsoft standard, Media
Transfer Protocol (MTP), which makes it possible to easily transfer content back and forth between your
phone and a Windows PC. For Apple Mac computers, a special application, BridgeforMac, is available
offering built-in support for MTP; this application can be downloaded from the Xperia™ SP Support page.
Note that you do not need to back up or make a copy of applications that you have downloaded from
Google Play™. They can normally be downloaded again if, once you have set up your Google account to
work in a new phone phone (or a phone where the memory has been completely erased).
Note 1:
As noted above, some Android phones, including Sony Mobile devices from 2012, and Sony Ericsson
devices from 2011 and earlier, do not use a single “Internal Storage” for both applications (and their data)
and user content. Instead, these devices use either an external SD card for user content, or a
corresponding area of internal memory to reproduce the functionality of an SD card. In such devices, there
is a fixed limit between the application area (“/data”) and the user content area (“/sdcard); with the result
that user content can be filled, stopping the taking of new pictures for example, while there is still
considerable free space in the application area; or vice versa, stopping the download and installation of
new applications even though there is free memory in the content area.
Note 2:
Some devices with an integrated storage have abandoned the distinction between the application area
and the content area when it comes to Factory Data Reset. As a result, there is no choice to do Factory
Data Reset and preserve content; in such devices, all content is mandatorily and completely deleted from
the device when a reset is performed.
In contrast, Sony Mobile has done the integration in a manner which makes it possible to preserve user
content in this situation; therefore, when performing a Factory Data Reset, the default will still be to only
remove applications and their data, and an option box must be checked if also all content is to be
removed (as might be desirable when selling the device second-hand, for instance).
Note 3:
For a developer, it is important to note that from a programmer’s point of view, the location names used to
refer to the different memory areas described in Note 1 are still valid; i.e., the area used for application (/
data) is still present, as is the area used for content (/sdcard).

In reality, “sdcard” is a so-called symbolic link to “/data/media”, but from inside an Android application, “/
sdcard” can still be used (for instance, use “sdcard/DCIM/100Android” to find all camera images).
Continuing to use /sdcard to access the content area ensures compatibility across different products and
Android releases in this regard.
