2.2.2. MANAGE STORAGE SPACE
To your Android device, the SD card can serve as an extension of your device’s internal
storage (which comes as 64 GB of flash memory to store the OS, applications and files)
other than a portable storage place.
Go to App Drawer (All Apps) | Settings | Storage to check usage of the
internal and external storage spaces.
By default, all the videos, photos and downloaded files are directly saved to the device’s
internal storage. If you have previously inserted and mounted an SD card as portable
storage, you could transfer/save photos & other media in this SD card; if the SD card is set
as internal storage, photos, files, and some apps could be moved to the SD card.
The SD card is used for storing anything on this
device only, including apps and photos. Requires
formatting that prevents it from working with
other devices.
