Galaxy S6 :: Screen Wakes Up By Itself

the quick version is my home button rarely does anything any more and the screen wakes up by itself from being asleep after anywhere from 3 seconds to 12 seconds.Non-rooted Galaxy S6, by the way. I did a factory reset last week, just because things were getting sluggish. It went well, things were back to speed, and I reinstalled the essentials I wanted. Last night I noticed my phone kept waking itself up over and over again. Then I noticed the home button wasn't doing anything. I rebooted it and it didn't change a thing. After a little more time, the power button also stopped responding. I couldn't even do an emergency reboot with those two buttons disabled. I even tried sticking it in the freezer for a few minutes to see if it was too hot. Google told me about the on screen menu thing to emulate the softkeys so I was able to use that to get around and do reboots.

I hadn't installed any new apps in the last 24 hours, but what the heck, I did another factory reset. I had the option to restore all the apps and settings from 1 day ago, so I chose that. The problem still was there. Dang it, I thought I should not have restored those apps, so I did another reset, this time a totally clean one. The problem not only still happened after the reset, it was doing it during the reset, if the screen went to sleep during a step in the factory reset, the glitch would wake it back up in a few seconds.

I decided last night to just turn it off and charge it fully and hit the Sprint store in the morning. Oddly while charging with the phone powered off, the green battery display would go off and on the whole time it charged.

In the morning I turned the phone on....and NO problems. (of course) For 2 hours not one glitch. So just before leaving for work it starts happening again. Another factory reset at work and a system update from Samsung and still, the problems are there.
