Answer to "iPhone 6 gets really hot after screen replacement"This is happening to my wife's phone right now. I replaced the screen on her 6s. The repair went very smoothly, and the phone worked great for a short time. Now the screen freezes, does not respond to touch, and today she told me a message popped up telling her the phone was over heating and that it needed to cool down before use. She restarted it and it worked, but now there is a white line on the screen below the front facing camera. This sounds like the problem above. I don't have the time to replace the parts beyond the screen. Any one with a wife will know that you can't keep them from their phone too long without consequences. I recall the camera, speaker and ambient light sensor part of the screen repair was a little difficult.
