Ordered 4 through Verizon online for my corporate account on the day they became available. 3 for my employees worked fine, but mine would not go into 4G. Verizon sent a replacement to my hotel (was on business travel by then) and it worked fine until last night - screen went away as I was looking at it. Power, Power+ down volume, Power + up and down volume, nothing gets this thing to power up. Even tried charging and the above steps, but it is still dead. Going to Verizon store to swap out today. Trying really hard to lie this phone!
