Memory and storage

Your device has different types of memory and storage possibilities for photos, apps and other files:

•The internal storage is about 32 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, call logs, contacts, messages, calendar events, photos, videos and music.

•You can use a removable memory card of up to 128 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.

•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.
