@shwanakamal this "on it still vibrate but show nothing?" means that your display is not working. Yes, it absolutely can be from being to hot outside. But it should start again once it does cool down. "And the right part beside the camera" This we will have to check separate since getting hot means there is a short somewhere. Does it still get hot even when your phone is normal temperature? I think it's time for a look at what you have going on in the inside. For now, you do recognize you may need a new screen. You okay with a multimeter and checking a few things.

@shwanakamal this is what you should see with the back off. Now, can you narrow it down a bit about where it gets hot? Top part of the board, bottom part of the board?
