Product overview  
Highlights  
• 10.1-inch Full HD display with the latest BRAVIA® TV technology and X-Reality™ for mobile picture  
engine  
• S-Force Front Surround audio technology and Digital noise cancelling  
• The slimmest (6.4mm) and lightest (under 450g) waterproof tablet on the market*

The sharpest images with the most vivid colours  
Whether you are in bright daylight or in low light conditions, with the Xperia™ Z2 Tablet, you still can  
watch entertainment in full, vivid colour. The Xperia™ Z2 Tablet’s 10.1-inch Full HD display is embedded  
with the latest Sony BRAVIA TV technology expertise. At its core, TRILUMINOS™ Display for mobile  
creates a wider palette of rich, natural tones while brand new Live Colour LED technology provides the  
world’s most vivid and deepest colours on a tablet without the risk of oversaturation. Finally, unique to  
Sony, the X-Reality™ for mobile picture engine analyses each image to optimize colour, sharpness and  
contrast while super resolution reproduces lacking pixels. So you always get the sharpest images and  
videos, even from low quality content such as still pictures and web videos.  
The clearest sound quality  
When holding a tablet your hand can sometimes get in the way of the speakers. But with Sony’s new S-  
Force Front Surround audio technology coming at you via specially positioned speakers at the front of the  
Xperia Z2, you can enjoy dynamic sound. And if you are on the move and want to watch your favourite  
film, you no longer need to worry about the background noise from busy streets, noisy trains or even on  
flights. The Xperia™ Z2 Tablet supports digital noise cancelling technology which reduces ambient noise  
by up to 98%. Just make sure you use your Digital Noise Cancellation Headset.  
The world’s slimmest and lightest tablet  
The Xperia™ Z2 Tablet is created with a sleek design using premium material, which makes it the Xperia™  
Z2 Tablet slimmest (only 6.4mm) and lightest (under 450g) waterproof tablet on the market. Specifically,  
the Wi-Fi-only model weighs 426g while the 4G LTE modem model weighs 439g. Every single detail has  
been carefully crafted so you can enjoy a tablet that is not only beautiful to look at, but is also extremely  
portable and comfortable to hold with just one hand.  
The durable waterproof tablet  
The Xperia™ Z2 Tablet is designed with a display that is scratch resistant and a body that is entirely  
waterproof so it can handle whatever life throws at it. You can even watch a movie in the bath while you  
relax at the end of the day, or record a video in the pool while on holiday. The Xperia™ Z2 Tablet is built to  
follow you wherever you go.  
The world’s most powerful tablet  
The Xperia™ Z2 Tablet combines the fastest processor in a tablet with Sony’s latest battery saving  
technology, for fast and long lasting performance. We developed the Snapdragon 801 processor with  
speeds of up to 2.3 GHz so that just the right processing components are used at the right power levels  
for any given task. So, share your photos and files faster and stream your audio and video more smoothly  
with the industry’s only third generation 4G LTE modem, delivering twice as fast 4G user speeds. Plus, a

generous 3GB of RAM ensures plenty of memory capacity. And if that wasn't enough, you can enjoy  
sharp, realistic mobile 3D gaming with the enhanced graphics capabilities of the newest Adreno 330 GPU,  
which delivers a 20% performance improvement over the previous generation.  
A longer-lasting battery  
A 6000mAh ion battery and STAMINA Mode features are introduced in the Xperia™ Z2 Tablet, providing  
up to 10 hours of uninterrupted multimedia usage. Extended standby time maximises your battery lifetime  
by preventing unwanted applications and data communication from running in the background when the  
display is turned off. So you won’t miss any important calls. Extended usage runtime can dynamically tune  
the hardware parameters to reduce performance in favour of longer usage time, so you gain 15 percent  
power saving even when you’re extra active. With STAMINA mode you can also benefit from extended  
music playback, allowing you to listen to music for more than 100 hours without having to recharge your  
battery. And that is something!

White paper | Xperia™ Z2 Tablet  
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 2014 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 built-  
in 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™ Z2 Tablet has about 3 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  
February 2014  
 
 
White paper | Xperia™ Z2 Tablet  
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™ Z2 Tablet, about 11 GB of Internal Storage is available out of the  
box.  
Please note that in Sony Mobile 2014 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 2014 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™ Z2 Tablet 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™ Z2 Tablet  
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.
