You've got to be kidding me!
My phone flat out blinked off and now I can't turn it on. The battery is built in so you can't "reset" it.
I type the words 'Droid 4' into Mr. Google and IMMEDIATELY 'Droid 4 won't turn on' is the first search option.
Grrrrrrrrrrrrrr...
Guess who is NOT amused to have to go to Verizon.
Have you had any problems with your phone recently?
