Smart, sleek and waterproof*
Building upon the rich history of Sony’s craftsmanship, Xperia® Z1
S
has been carefully crafted using only clean lines and premium materials. With OmniBalance™ design, this smartphone offers balance and symmetry in all directions, creating a smartphone that feels wonderful to hold in every angle. Both the front and back are made of durable tempered glass, reflecting the world around you while allowing you to get so immersed in content that the hardware virtually disappears. And due to its IP55/IP58 rating, this slim and sleek smartphone is waterproof and dust resistant. In fact, even the headphone jack is waterproof.
*In compliance with IP55 and IP58, Xperia® Z1
S
is protected against the ingress of dust and is waterproof.
Provided that all ports and covers are firmly closed, the phone is (i) protected against low pressure jets of water from all practicable directions in compliance with IP 55; and/or (ii) can be kept under 1.50 meters of freshwater for up to 30 minutes in compliance with IP58. The phone is not designed to float or work submerged underwater outside the IP55 or IP58 classification range that may lead to your warranty will being void.
The world’s best camera in a waterproof smartphone*
Sharper. Clearer. Brighter. That’s what Sony’s industry leading compact digital cameras give you. And now with Xperia® Z1
S
, we have created a groundbreaking smartphone built with the similar components, giving you stellar picture and video quality. By combining the large 1/2.3” 20.7MP Exmor RS™ for mobile image sensor, Sony’s award-winning G Lens, and intelligent BIONZ™ for mobile image processing engine, the results are nothing less than amazing. The light-sensitive 27mm wide angle lens comes with an aperture of F2.0. Wide apertures mean that bokeh – the way the lens renders out-of-focus points of light – will be naturally incorporated in images produced. The large high sensitivity sensor is equivalent to the sensor size used in Sony’s Cyber-shot™ digital still cameras, which together with the intelligent noise reduction capabilities of the image processing engine and the sensitive ISO 6400 enables incredibly clear low-light pictures without sacrificing detail. The high pixel resolution, aspherical lens and BIONZ™ for mobile super resolution technology enables zoom without quality loss - just like an optical zoom, while the high shutter speed reduces any risk of blurry footage. Images are delivered with super sharpness, clarity and brightness.
*The Z1
S
camera combines the world’s largest image sensor (1/2.3 inches), the highest resolution (20.7
MP), and the brightest lens (F2.0) available in a slim (8.5 mm) waterproof (IP55/IP58) smartphone. Verified by Strategy Analytics on 10/30/13, www.sonymobile.com/testresults/.

Our best colour and sharpness
Built with the latest Sony BRAVIA® technologies optimised for mobile, Xperia® Z1
S
incorporates a large high-resolution 5” Full HD TRILUMINOS™ Display for mobile, for a wider palette of rich, natural colours – just like having a broader range of colour pencils to draw from. With Sony’s exclusive X-Reality™ for mobile picture engine, everything you watch – from HD movies to web videos and photos – is analysed and selectively processed to deliver clean, clear, and lifelike pictures. In addition, the Intelligent Super
Resolution technology finds and reproduces lacking pixels, so you’ll always be able to enjoy the sharpest videos, preventing your entertainment from being spoiled by low resolution videos. The display comes with a 1920 x 1080 progressive scan, for incredibly crisp pictures free of jagged edges. Paired with a pixel density of 441 pixels per inch, you get pictures that are razor sharp and incredibly bright.
Blazing fast performance
Performance that never lets you down. Isn’t that what we’re all craving for? With Xperia® Z1
S
, that’s exactly what you get. This smartphone supports super-fast LTE networks, giving you access to entertainment anytime and anywhere. With the latest Qualcomm Snapdragon™ 800 quad-core 2.2 Ghz processor with 2GB RAM, this smartphone comes with ultra-fast performance and breathtaking graphics.
So stream your favourite YouTube™ clips and download the latest podcasts.
Better battery life
Smartphones use a lot of power, even when you’re not actively using them. All those apps that you have on your phone may still be running in the background, draining your battery. Battery STAMINA Mode saves you wasted battery drain. It recognises when you’re not using your display and automatically turns off the functions you don’t need, while keeping the notifications you want. As soon as you press the power button to wake up your screen, everything is up and running again. So not only do you have an enormous
3000 mAh battery, Battery STAMINA Mode helps you cleverly maximise every bit of that energy.
Background defocus – Get a whole new perspective
Exclusive to the Xperia® Z1
S
, the Background Defocus app adds a manual focus effect that you would not expect to find in a smartphone camera. Background Defocus lets you sharpen objects in the foreground while slightly blurring the background for more artistic, professional-looking photos.
Social live – Broadcast your precious moments live
Start recording a video and broadcast these moments as they happen, live, on Facebook. Whether it’s your best friend’s wedding, your baby’s first steps, or your husband’s cooking skills – family and friends can see the story unfold, in real-time. Check out the comments and “likes” while you’re shooting, as they appearing in your camera viewfinder.
Info-eye™ – An innovative way to gain information
Snap a photo of a specific object and Info-eye™ can tell you more about what it sees. Where was that bottle of wine made and how good is it? What is that book all about? How tall is the Eiffel Tower and what restaurants are nearby? Info-eye™ is an innovative way to search for information on things that interest you – right through your camera viewfinder.
Timeshift burst – Catch the best shot
Capture the right moment, or all the moments, even when things are in motion. With Timeshift Burst,
Xperia® Z1
S
’s camera captures 61 frames in just 2 seconds – starting 1 second before you press the shutter. All 61 frames fan out like a deck of cards for you to scroll back and forth to find your favorite.
Keep all of them and scroll back and forth repeatedly to create your very own digital flip book.

AR effect – Add some fun to your shots
Put some fantasy and fun in your photos with AR (Augmented Reality) effect. Choose between several animated themes ranging from disco to dinosaurs to under-the-sea. Capture a creative selfie using the front-facing camera and Masquerade theme. The themes are fully customizable, so you can select just how many fish you want or the mask that you’d like to wear.

Memory in Android™ devices
To use Android devices efficiently, users should be aware of the different types of device 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 want to optimise their programs to make the best possible use of the resources in the device.
Generally, all Android devices 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 device uses an external SD card or an internal memory chip. Any information specific to the particular device model described in this White
Paper is noted as such.
Types of memory
The types of memory described and numbered below are consistent with the terminology used in Sony mobile device menus and in other content relating to 2013 Xperia™ devices:
1. Dynamic Memory (also known as RAM) is used by applications that run when the device is turned on.
The amount of Dynamic Memory influences how many applications and operating system services can run at the same time. The Android 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), device speed will eventually be impacted. This is the main reason that a device cannot be indefinitely upgraded to newer releases of Android™.
If you experience problems with RAM, for example, if the device runs slower than usual or if the Home application restarts frequently when you leave an application, you should minimise the use of apps that run all the time. Such apps could include, for example, applications that frequently download social networking 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 > Apps > Running. 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 device 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 device may run slower after an update.
The Xperia® Z1
S
has about 2 GB of RAM available to the Android OS and applications, of which about
200 MB is already used out of the box.
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.
19 January 2014
White paper | Xperia® Z1
S
This type of memory is used to store all application downloaded from the Google Play™ Store (and other sources) as well as their settings and data (such as emails, messages and calendar events, for example). All applications have an allocated area which no other applications can access and where the application data can be stored.
Some game applications also store content such as game music and game level information outside their own designated area. In most cases, an application can choose to save its data in a location of its own choosing (outside the protected application settings area). Generally, such content is not deleted when an application is uninstalled; it must be removed manually by connecting the device to a computer with a USB cable, or by using 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. Examples of such usage are the saving of data by applications; the downloading and installation of new applications; the downloading of free or paid content; and the shooting of 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 shoot.
If the Internal Storage starts to get full, the device 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 Internal
Storage. If not, you should consider removing some apps that you seldom use, or move content that you do not frequently access to safe storage.
You can see approximately how much Internal Storage is free in Settings > Storage > DEVICE
MEMORY. You can also view more detail about how much memory is used by applications in
Settings > Apps. In the Xperia® Z1
S
, about 12 GB of Internal Storage is available out of the box.
Please note that in Sony Mobile 2013 products, “Internal Storage” is now the combination of what was previously known as “Device Memory” or “Phone Memory” (for applications and their data – also previously known as “/data”) and “Internal Storage” (for user’s content – also previously known as “/ 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 device with a large internal memory as it does in a device with ONLY a memory card slot.
Generally, since most applications expect only a single location for storage, such applications will not generally allow you to SAVE anything to the memory card (i.e., they do not offer the option to choose a storage location). However, some applications (for instance, the Sony Mobile “Camera” application) may actually allow you to do so. Other applications, 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 to access content
(for example, videos, photos and music) on a memory card inserted in this slot without any special consideration 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” or “SD 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 backup applications and file manger applications, have 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 device. If something should happen with the hardware, or if the device is lost or stolen, the data stored on the device’s internal memory is gone forever.
In a device 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® Z1
S
supports the Microsoft standard, Media
Transfer Protocol (MTP), which makes it possible to easily transfer content back and forth between your device and a Windows PC. For Apple Mac computers, a special application called Sony™ Bridge for Mac is available with built-in support for MTP. This application can be downloaded from the Xperia® Z1
S
Support page.
Note that you do not need to back up or make a copy of applications that you have downloaded from the
Google Play™ Store. They can normally be downloaded again after you have set up your Google account to work in a new device (or in a device where the memory has been completely erased).
Note 1:
As noted above, some Android devices, 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 build up and reach this limit. The consequence of such a limit being reached, for example, for the camera application, would be that no new pictures could be taken even if there was still a considerable amount of free space in the application area (or in the user content area). In such an instance, the download and installation of new applications would also not be possible, even if there was enough free memory in the content area.
Note 2:
Some devices with integrated storage have abandoned the distinction between the application area and the content area when it comes to a Factory Data Reset. As a result, there is no option in such devices to perform a 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’s memory integration solution makes it possible to preserve user content in this situation. Therefore, when performing a Factory Data Reset, the default action will still be to only remove applications and their data, and an option box must be checked if all content is to be removed as well (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 programming 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 applications (“/ data”) is still present, as is the area used for content (“/sdcard”).
In reality, “sdcard” is a so-called “symbolic link” to “/data/media”. However, from inside an Android application, “/sdcard” can still be used. For example, you can use “sdcard/DCIM/100Android” to find all camera images. The continued use of “/sdcard” to access the content area ensures compatibility across different products and Android releases in this regard.
