Restarting and resetting

You can force your device to restart or 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
some of your personal data, such as music and pictures. This action is sometimes
necessary if your device stops functioning properly, but note that if you want to keep any
important data, you have to first back up this data to a memory card or other non-
internal memory. For more information, see
page 129.
Your device may fail to restart if the battery level is low. Connect your device to a charger and
try restarting again.
If you are using a device with multiple users, you may need to log in as the owner, that is, the
primary user, to reset your device to its original factory settings.
To force your device to restart
1
Press and hold down the power key
2 In the menu that opens, tap Restart, then tap OK to confirm. The device restarts
automatically.
To force the device to shut down
1
Detach the cover of the micro SIM card slot.
2
Using the tip of a pen or a similar object, press and hold down the OFF button
until the device shuts down.
Do not use overly sharp objects that could damage the OFF button.
