Resetting and restarting

You can reset your device to its original factory settings, with or without deleting all of

your personal data. This action is sometimes necessary if your device stops functioning

properly. You can also force your device to shut down in situations where it hangs or

won't restart normally. When you restart a device after forcing it to shut down, no

settings or personal data get deleted.

Before you perform a reset, make sure to back up any important data saved on your device.
