It comes and goes as it wants. If I touch it, then it puts a semi-transparent film over the screen and the screen and buttons will respond to swipes, but if I try to touch anything, then it droid becomes unresponsive. I've only found that I have to take the battery out to get the phone to go back to normal mode. I feel as if this is someone that has hacked my phone and waiting to watch me access critical information. Someone please advise.
