Product overview  
Xperia™ Tablet Z – The precision engineered HD  
tablet  
How tablets should have been from the beginning.  
So brilliantly vivid, you feel like you’re there  
Think about the sharpest, most vivid TV picture. Now imagine it on a tablet. Xperia™ Tablet Z delivers the  
kind of immersive viewing you’d normally only get with an HDTV. Created by the people behind BRAVIA®  
TVs, Xperia™ Tablet Z brings Sony’s expertise to an Android™ tablet. The brilliant 10.1” Reality Display™  
is powered by Mobile BRAVIA® Engine 2, which enhances the clarity and richness of every image. This  
HD tablet boasts the fullest colour display, too. For bluer blues, greener greens and seriously killer  
sunsets. With Xperia™ Tablet Z you meet a world so vivid, everything else pales in comparison.  
Minimal yet distinctive – OmniBalance design  
The design of Xperia™ Tablet Z is focused on creating balance and symmetry in all directions. We call it  
OmniBalance design. OmniBalance™ design balances technology vs. design, letting you get so totally  
immersed in the content that the hardware disappears.  
Xperia™ Tablet Z has subtly rounded edges and smooth, reflective surfaces on all sides, which are held  
together by an innovative skeleton frame. The glass-paneled front has a seamless surface and enhanced  
reflective coating.  
Lightning speed performance – Quad core processor  
We’ve matched the latest Sony software with the powerful Qualcomm® Snapdragon™ S4 Pro processor.  
This advanced 1.5 Ghz quad core processor gives you maximum performance and speed, and incredible  
graphics, without draining your battery. Run multiple apps simultaneously, surf the web with no loading  
time, and stream videos without a break. The Snapdragon S4 Pro processor is asynchronous, which  
means each core is powered up and down independently. So you get the precise amount of power when  
you need it, without wasting power when you don’t.  
One-touch connectivity from Sony  
Sharing with friends and connecting your world has never been easier. Based on NFC (near field  
communication), our One-touch functions connect one device to another in a single tap. No wires, cables,  
or fiddling with settings necessary.  
• One-touch sharing: Share photos, music and more between your tablet and smartphone or NFC-  
enabled laptop.  
• One-touch listening: Play the music on your tablet or smartphone through a wireless speaker.

White paper | Xperia™ Tablet Z LTE  
Memory in Device  
To use Android devices efficiently, users should be aware of the different types of 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 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 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. 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), device 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 device 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 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.  
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  
15

White paper | Xperia™ Tablet Z 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 device 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 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 device  
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 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 “device 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 device with large  
internal memory, as in a device 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”.

White paper | Xperia™ Tablet Z 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 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™ Tablet Z 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, BridgeforMac, is available  
offering built-in support for MTP; this application can be downloaded from the Xperia™ Tablet Z 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 device (or 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 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™ Tablet Z – The precision engineered HD  
tablet  
How tablets should have been from the beginning.  
So brilliantly vivid, you feel like you’re there  
Think about the sharpest, most vivid TV picture. Now imagine it on a tablet. Xperia™ Tablet Z delivers the  
kind of immersive viewing you’d normally only get with an HDTV. Created by the people behind BRAVIA®  
TVs, Xperia™ Tablet Z brings Sony’s expertise to an Android™ tablet. The brilliant 10.1” Reality Display™  
is powered by Mobile BRAVIA® Engine 2, which enhances the clarity and richness of every image. This  
HD tablet boasts the fullest colour display, too. For bluer blues, greener greens and seriously killer  
sunsets. With Xperia™ Tablet Z you meet a world so vivid, everything else pales in comparison.  
Minimal yet distinctive – OmniBalance design  
The design of Xperia™ Tablet Z is focused on creating balance and symmetry in all directions. We call it  
OmniBalance design. OmniBalance™ design balances technology vs. design, letting you get so totally  
immersed in the content that the hardware disappears.  
Xperia™ Tablet Z has subtly rounded edges and smooth, reflective surfaces on all sides, which are held  
together by an innovative skeleton frame. The glass-paneled front has a seamless surface and enhanced  
reflective coating.  
Lightning speed performance – Quad core processor  
We’ve matched the latest Sony software with the powerful Qualcomm® Snapdragon™ S4 Pro processor.  
This advanced 1.5 Ghz quad core processor gives you maximum performance and speed, and incredible  
graphics, without draining your battery. Run multiple apps simultaneously, surf the web with no loading  
time, and stream videos without a break. The Snapdragon S4 Pro processor is asynchronous, which  
means each core is powered up and down independently. So you get the precise amount of power when  
you need it, without wasting power when you don’t.  
One-touch connectivity from Sony  
Sharing with friends and connecting your world has never been easier. Based on NFC (near field  
communication), our One-touch functions connect one device to another in a single tap. No wires, cables,  
or fiddling with settings necessary.  
• One-touch sharing: Share photos, music and more between your tablet and smartphone or NFC-  
enabled laptop.  
• One-touch listening: Play the music on your tablet or smartphone through a wireless speaker.

White paper | Xperia™ Tablet Z  
Memory in Device  
To use Android devices efficiently, users should be aware of the different types of 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 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 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. 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), device 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 device 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 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.  
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  
15

White paper | Xperia™ Tablet Z  
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 device 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 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 device  
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 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 “device 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 device with large  
internal memory, as in a device 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 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™ Tablet Z 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, BridgeforMac, is available  
offering built-in support for MTP; this application can be downloaded from the Xperia™ Tablet Z 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 device (or 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 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.
