This issue exists in a different way for me. I have power button set to end phone call. At least I used to. I had to turn that option off because if I'm on speaker or have headphones plugged in and the screen turns off, it won't turn back on!! I hate it!
I'm naked on the front. It's just some other issue. Only way to turn the screen on would be to plug the charger in or out. So I just turned that option off with the power button.
It sucks
