Memory and storage
Your device has different types of memory and storage possibilities for photos, apps
and other files:
The internal storage is about 1.7 GB and is used to store downloaded or transferred
content along with personal settings and data. Examples are alarm, volume and
language settings, emails, bookmarks, contacts, calendar events, photos, videos and
music.
You can use a removable memory card of up to 32 GB to get more storage space.
Most applications can read data from a memory card but only certain apps can save
files to this type of memory. You can, for example, set the camera application to save
photos directly to the memory card.

You may have to purchase a memory card separately.
