Turning The Device On And Off - Samsung SM-T380 User Manual

Basics
Do not remove external storage, such as a memory card or USB storage, while the
device is transferring or accessing information, or right after transferring data. Doing
so can cause data to be corrupted or lost or cause damage to the external storage or
device. Samsung is not responsible for losses, including loss of data, resulting from
the misuse of external storage devices.
Formatting the memory card
A memory card formatted on a computer may not be compatible with the device. Format the
memory card on the device.
Launch the Settings app and tap Device maintenance → Storage → → Storage settings
→ SD card → Format.
Before formatting the memory card, remember to make backup copies of all
important data stored in the memory card. The manufacturer's warranty does not
cover loss of data resulting from user actions.
