Reboot the phone
The reason to perform a reboot might be a persistent problem that is im-
possible to solve or if your device becomes frozen and unresponsive. This
device has an internal battery and therefore the hardware cannot be re-
booted by removal of the battery.
Should you need to reboot the phone press and hold the

Power button and the Volume up key simultaneously for more than 8
seconds to reboot it. After the reboot, the phone will restart
automatically.
