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.
