Finding the identification number of your device
Your device has a unique ID (identification) number. On your device, this number is
referred to as the IMEI (International Mobile Equipment Identity). You should keep a
copy of this number. You may require it, for example, when you access the Xperia™
Care support service and need to register your device. Also, if your device is stolen,
some network providers can use this number to stop the device from accessing the
network in your country.

Memory and Storage
Your device has different types of memory and storage options.
•
The
internal storage
is about
4.9
GB and is used to store downloaded or transferred content along with
personal settings and data. Some examples of data stored to the internal storage are
alarm, volume and language settings; email; 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, such as 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.

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:
•
Always have more than
100
MB of free internal storage and more than
100
MB of free
RAM available.
•
Close down running applications that you are not using.
•
Clear the memory cache for all applications.
