Storage
View memory information for your device and memory card, or format a memory card. On the Settings screen, tap Storage.
Formatting a memory card permanently deletes all data from it.
The actual available capacity of the internal memory is less than the specified capacity because the operating system and default apps occupy part of the memory. The available capacity may change when you upgrade the device.
