Memory and Storage

Your device has different types of memory and storage options.
•
The
eMMC (embedded multimedia controller) memory
, which consists of the system memory and the internal storage, is about 32 GB. The
system memory is used for the Android™ operating system and for most pre-installed
applications. The internal storage 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; email; 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 (with their data) can be moved to this type of memory to free up internal
storage. Some apps, such as the Camera app, can save data directly to a memory card.
•
The
dynamic memory (RAM)
is about 3 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.
