my s4 active screen turns white and gray

[Mellie Molloy]

I need help figuring out what is going on with my phone. It turns blue and looks pixelated and then fades into a gray/white background with vertical lines. This happens every time I make or receive a phone call and now when I charge my phone it sometimes happens. I have not gotten my phone wet or banged it on anything. In fact, it started out of nowhere when my step daughter was on the phone and I know she didn't do anything to it because I was watching her. I love Samsung and galaxy phones, but this is the second problem I've had with these phones. I had to get my other phone replaced because the kit kat update ruined my touch screen when it came out.

Mine just started doing the same thing. Did you ever find out what's doing that? Because I have to take my battery out then put it back in then it works fine but then about 20 mins later it dies the same thing.
