I just looked down at my phone and it is displaying a dimmed out Verizon screen as if it is in the process of shutting down. I just had it charged to over 80% so the battery power was fine. It has been doing this for about twenty minutes now and is completely unresponsive to any buttons of plugging it in to the charger. I know that it just went through an update yesterday but I have no idea what it is doing and I cannot get it to turn back on or off. PLEASE HELP!!
