I have a Nexus 6 that has a shattered screen but has been working like normal. I dropped it just now and the screen will not come on. I can hook it to my pc and it makes that noise in Windows when you hook up a device to usb, my wireless charger will also light up when I set it on it like normal. I am thinking the screen just finally died but I dont want to spend 175 bucks for no reason if possible
