@bobcat1981 That is true here is what a red one looks like: Its even more creepy when see in video it looks like my phone has been possessed or something:

At first I had this same exact problem where my phone would look like it was evil with this red glow but still worked. At first, I thought it was the proximity sensor on the front camera flex which it may be for you but it wasn’t for me and I even tried connecting it to iTunes and updating and restoring the iPhone thinking it was a hardware issue but that did not seem to be the case. What worked for me was replacing the whole lcd screen, something with the connection cables of the screen must have been causing this problem and switching out the lcd screen fixed this problem.

I fixed this a couple days ago and the problem was that I needed to replace the battery. Works great now!
