Memory and storage
Your device has different types of memory and storage options.
•
The internal storage is about 4.5 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; emails; 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, for example, 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 250 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 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.
