White paper | Xperia™ E4 Dual  
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 data such as music, photos and  
videos is saved; how many apps can be downloaded from Google Play™; and how photos can be copied  
to a PC.  
Information regarding memory presented in this section may be useful to developers when optimising  
applications for mobile devices.  
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 2015 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. Social networking apps that connect and update their data online and animated  
backgrounds are examples of apps that are always running and affect RAM performance. To minimise  
RAM issues, 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 a result, the device may run  
slower after an update.  
The Xperia™ E4 Dual has 1 GB of RAM available to the Android OS and any installed applications. 200  
MB of the total RAM is in use during normal operation when the user starts using the device 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.

White paper | Xperia™ E4 Dual  
3. Internal Storage is referred to as "working" memory. It can be compared to the C: drive on a PC or to  
the startup disk on a Mac.  
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 for application data. Memory dedicated to an  
application is inaccessible to other applications.  
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 added user content. For example, photos taken using the device's  
camera, media files downloaded from the Internet and file transfers are stored in this area. Typical user  
content includes:  
• photos  
• movies  
• music  
• Email attachments  
Internal Storage will tend to fill up as a result of normal usage. Devices with a large initial Internal  
Storage can handle more applications and store more user content.  
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 external storage.  
You can see approximately how much Internal Storage is free in Settings > Storage > DEVICE  
MEMORY. You can also view more details about how much memory is used by applications under  
Settings > Apps. In the Xperia™ E4 Dual, about 5 GB of Internal Storage is available out of the box.  
Please note that in Sony Mobile 2015 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 changes in Internal Storage were made so that memory usage could be more flexible  
and to allow encryption of user content.  
Memory card slot  
Some products include both a large internal memory and a built-in memory card reader. Android manages  
devices with a built-in memory card reader and internal memory differently from a device that includes  
only a built-in memory card reader.  
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 2015 Sony Mobile products. As  
described in the previous section, 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™ E4 Dual supports 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™ E4 Dual 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:  
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. When the user content reaches this limit, no additional data can be added using  
any application. For example, the camera application would no longer be able to capture additional  
photos even if a considerable amount of free space was available in the application area. This limit also  
applies to the application area. Downloading and installing new applications would not be possible even if  
there was enough free memory in the user 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 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).

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 “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.
