Hello, I have had an iPhone 11 for about two months now. I was watching you tube and the screen randomly went black and wouldn't turn on. I tried to restart it by holding the lock button and the upper volume button, i tried force restarting it many time by pressing the up then down volume and then holding the lock button, i left in on a charger for two hours and got nothing, and i plugged the phone in to a laptop with iTunes and NOTHING has happened. I just purchased this phone brand new and don't understand why this happened. Does anyone have advice or similar stories?
