Storage and memory
Your device has several different storage and memory options:
•
The internal storage stores downloaded or transferred content along with personal
settings and data.
•
You can use a removable memory card to get more storage space. Media files can
be moved to this type of memory to free up internal storage.
•
The dynamic memory (RAM) cannot be used for storage. RAM is used to handle
running applications and the operating system.
You can purchase a memory card separately.
Improving memory performance
Your device memory 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 try to keep at least 500 MB of free internal storage available.
•
Close 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 the
card. Note that when you format the card, all content is erased.
If you are sharing a device with multiple users, you must log in as the owner, that is, the
primary user, to be able to perform certain actions, like transferring data to the memory
card and formatting the memory card.
