Memory and storage
Your device has different types of memory and storage possibilities for photos, apps
and other files:
•The internal storage is about 12/25 GB and is used to store downloaded or
transferred content along with personal settings and data. Examples are alarm,
volume and language settings, emails, bookmarks, calendar events, photos, videos
and music.
•You can use a removable memory card of up to 128 GB to get more storage space.
Most applications can read data from a memory card but only certain apps can save
files to this type of memory. You can, for example, set the camera application to save
photos directly to the memory card.
•The dynamic memory (RAM) is about 3 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.
•Close down running applications that you are not using.
•Clear the cache memory for all applications.
•Uninstall downloaded applications that you don't use.
•Transfer photos, videos and music from the internal memory to the memory card.
•If your device can't read content on the memory card, you may need to format it.
