iPhone 7 overheating on iOS 10.0.2

Hello,

when I upgraded to iOS 10.0.2 on my iPhone 7 128GB my phone girs on overheating everytime time I use it.

Its so hot that it is hard to hold it on my hands.

what can I do? Anybody else got this problem?

I think that Apple should investigate on it.

Let me know if you're having this problem
