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 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, call logs, contacts, messages, calendar events, photos, videos and music.
• You can use a removable
memory card
of up to 32 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 2 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 memory cache 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.
