What do I do if the phone won't turn off?

If the phone cannot be turned off by pressing the power button and volume up key simutaniously, you can do the following:
1. Check if the button is faulty.
2. Check if the mobile phone is in a state of crash, or is stuck. Press and hold the power button for over 12 seconds to force restart the phone.
4. If it is invalid, please uninstall and delete the recently downloaded software.
5. We recommend you back up the data and restore the phone to factory settings.
If the issue persists, contact the Nothing Support Team for further assistance.
