Glass Screen heating up

[barros]

Hi, I bought an 8X a few days ago and I'm pretty happy with the phone and with the OS but I have a problem with it, if I play a game for a few minutes the glass screen heats up to the point of burning my face or my fingers if I touch it. I'm on my second phone, I exchange the first one for the same thing.
Is it normal, is it supposed to heat up that way?

Thanks

It's definitely not normal. And this is the first time I've seen a post about the front heating up. Plenty about the back of the phone.

Also my phone heating up on the screen but not so much @barros say.
I have seen this reaction when my phone is at the sun or when I playing 3D games.

It's definitely related to 3D games, Asphalt 7 and Batman are the worst, they heat up the phone to the point that I can't touch the bottom half of the screen.
Since I'm on my second 8X, and both did the same thing I really don't think this is an isolated incident, or maybe I'm just not that lucky

My screen heating up too, the upper left part of the screen. Lumia 820.
