Memory and storage Your device has different types of memory and storage options.

content along with personal settings and data. Some examples of data stored to the internal storage are alarm, volume and language settings; emails; bookmarks;
calendar events; photos; videos and music.
• You can use a removable memory card with a storage capacity of up to  32 GB to get
more storage space. Media files and some apps (with their data) can be moved to this type of memory to free up internal storage. Some apps, for example, the Camera
app, can save data directly to a memory card.
• The dynamic memory (RAM) is about  1 GB and cannot be used for storage. RAM is
used to handle running applications and the operating system.
You may have to purchase a memory card separately.Read more about the use of memory in Android devices by downloading the White paper for
your device at 
www.sonymobile.com/support.
Improving memory performance
The memory in your device tends to fill up as a result of normal usage. If the device
starts to slow down, or applications suddenly shut down, you should consider the
following:

RAM available.
• Close down running applications that you are not using.
• Clear the cache memory for all applications.
• Uninstall downloaded applications that you don't use.
• Move applications to the memory card if the internal storage is full.
• Transfer photos, videos and music from the internal memory to the memory card.

Managing files using a computer
Use a USB cable connection between a Windows ®
 computer and your device to
transfer and manage your files. Once the two devices are connected, you can drag and drop content between your device and the computer, or between your device's
internal storage and SD card, using the computer's file explorer.
If you have a PC or an Apple ®
 Mac ®
 computer, you can use Xperia™ Companion to
access the file system of your device.
Transferring files using Media transfer mode via Wi-Fi ®
You can transfer files between your device and other MTP compatible devices, such
as a computer, using a Wi-Fi ®
 connection. Before connecting, you first need to pair
the two devices. If you're transferring music, video, pictures or other media files
between your device and a computer, it's best to use the Media Go™ application on
the computer. Media Go™ converts media files so that you can use them on your
device.
In order to use this feature, you need a Wi-Fi ®
 enabled device that supports Media transfer,
for example, a computer running Microsoft ®

especially recommended if you are updating your device software to a newer Android
version.
Using the Backup & Restore application, you can make a quick online backup of
basic settings and data with your Google™ account. You can also use this
application to back up data locally, for example, to the SD card in your device or to
