I have an iPhone 7 Plus running on iOS 10.2. I'm having great difficulty unlocking my phone when on a phone call. I can't get the screen to come on at all using the home button, and pressing the power button to do the same thing takes at least a dozen tries until the screen comes on. I've tried restoring as a new phone (no backup) and get the same results. Has anyone else experienced this on 10.2. I just updated a couple of days ago to 10.2 and the problem started then.
