Memory and storage
Your device has different types of memory and storage options.
•
The eMMC (embedded Multi-Media Controller) memory, which consists of the
system memory and the internal storage, is about 16 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; 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 (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 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.
