Top part of screen stops responding to touch occasionally

After a while the top part of my screen will completely stop responding to touch. I can't pull down the notification area or press anything on the upper portion of the phone. After, I reboot it works for about 30 seconds and then the top part of the screen will stop working again. The only thing that will fix it is to wait it out. Maybe a few hours later it will start working again. Then a couple days later and the same thing happens. I think maybe my phone is overheating from some app or something and then it causes this to happen for some reason. That would I guess explain why it starts working after while, because the phone had a chance to cool off

Anybody else experience this?
