Storage and Memory
Your device has several different storage and memory options.
•
The
internal storage
is about
16
GB and is used to store downloaded or transferred content along with
personal settings and data. Some examples of data saved to 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
128
GB to get more storage space. Media files and
some apps, along with their associated 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
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
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
100
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.
