Welcome from maze 16th, and today I'll show you how to put the device into fast boot mode now to get started, hold the power key and select power off when the device shuts off. You want to hold power key and volume down and, as you can see, we're now in fast boot mode. So that is how you put it into it and to leave it simply hold power key. There we go as you can see the phone shuts off and then reboots and there we go we're back in android. So if you found this very helpful, don't forget to hit like subscribe, and thanks for watching.
