Restarting and resetting

You can force your device to shut down in situations where it stops responding or won't

restart normally. No settings or personal data get deleted. You can also 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.

Your device may fail to restart if the battery level is low. Connect your device to a charger and

try restarting again.
