If a device hanged for some reason then you could pull the battery out to make the device a forceful shutdown and restart it manually.
But in case of a Galaxy S6 and an S6 edge where you have a non-removable attached battery beneath the metal and glass constructed body.
So what do you do if you have to reboot the Galaxy S6 when it hangs?
Do you think that Samsung has not taken this into account and simply released the phone to market?
Not to worry, because a simple three-button combination which doesn’t take more than a few seconds will help you out of this situation.
Press and hold the volume down + home + power/lock buttons for a few seconds until the phone shuts down by itself.
And then wait for a while for the phone to restart of its own. If not then you start the phone yourself.
In case you were wondering then get notified that this trick works for the Galaxy S6 edge as well.
