I've had my Droid Turbo 2 for about a month now. Every once in a while, the phone won't unlock from the original screen with a swipe down to the "lock" icon. It just freezes and won't do anything. I end up having to hold down the power button until it finally shuts down and restarts. Then it happens again, as soon as the screen sleeps. It's becoming a real pain in the ***. Any suggestions? Once I am successful with the swipe to unlock, I do have a pattern that I need to swipe to fully unlock the phone. HELP!
