How can I force the Nexus 6 to restart?
In the unlikely event that your device becomes unresponsive, try a force reboot or restart.
Warning: Don't attempt to remove or replace the battery - doing so may damage the battery and could cause burning and injury.
To reboot the device, press and hold the Power key for 10 - 20 seconds. The phone should power cycle and restart.
- Data on your phone will not be deleted with a force reboot/restart.
- Ensure that your device is charged to a minimum of 5%. If your battery is below 5%, then the device may not power on. A device that is completely drained should be charged for a minimum of 15 minutes using the provided charger.
If you are unable to force the devie to reboot or restart, you may need to perform a factory data reset (hard reset).
