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 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™ T3 has about 1 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.
17June 2014
Page 20
White paper | Xperia™ T3
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 under
Settings > Apps. In the Xperia™ T3, about 4.9 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.
18June 2014
Page 21
White paper | Xperia™ T3
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 “/sdcard1” 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™ T3 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 relevant Xperia™
T3 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.
