iOs 7 Flashlight on and slide to unlock not working

Anyone else run into a bug where you turn on the flashlight from the new slide up pannel and then press the top button to lock the phone but then the screen doesn't respond to finger swipes or touches? I was locked out of my phone with no response to any touches on the screen but the flashlight still on. I had to do a hard reset to finally get my phone to come back online.
