I replaced the screen in my sisters 6S a couple weeks ago, after which in testing I found the earpiece and face cam not working. Taking it back apart I found the ribbon cable had a small fracture in it, and as well the phone was generally hotter. So I just replaced the cable today, and upon initial testing, all worked but was getting overly hot. After powering down and letting it sit awhile, I tested it again and it seems to be the front cam itself generating the heat, it doesn't get warm/hot until I go to Camera and switch to face cam. The only cause I can think of is, the back of the cam having a metal cover shouldn't be coming into contact with the shielding piece installed over it that keeps everything in place. I also noticed there is a gap between the front of the camera and the screen. I'm pretty sure there wasn't anything in there originally to isolate the two, but i'm about to take it back apart and put a small piece of thin foam between the two to act as an isolater. Of course I'll double check the cable and make sure it didn't incur another fracture. Thoughts?
