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.
•
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.
•
If your device can't read content on the memory card, you may need to format the
card. Note that all content on the card gets erased when you format it.
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, such as transferring data to the memory
card and formatting the memory card.
