Its a rather simple fix. If you have a case take it off and find a hard surface and smack(use your own discretion if I have to explain the reaction of plastic hitting something hard return to your seat and continue likcking the window) the backside of phone near power button against it several times. Them place your thumb on power button push it in and roll your thumb around four a couple seconds. If it doesn't work repeat. Its basically a result of a poor button choice same reason the buttons rattle right out of the box. Its a temporary fix I have to do once every couple weeks but for the 2 weeks its problem free. At first sign of the problem resurfacing just do it again
