s21 5g wifi problem

Hello everyone
i got a new motherboard for my s21 5G
after I installed it I noticed that bluetooth is not working correctly ( turning off on its own)
so I opened the phone again and I noticed that I made a big mistake since I placed the mob under the side of the camera and almost bent the board.
Anyway after correcting Bluetooth is now flawless but now every time I do something that causes a small amount of heat like gaming or youtube short for 30 cause wifi to turn off if the phone is too hot wifi will refuse to turn on until it cools down.
am not sure where the wifi IC on this board could anyone help me?
the board was replaced because it was locked.

You damaged the board by not fitting it correctly. Some solder joints have cracked and when the board heats up they separate causing the issue you describe. Any bending of a circuit board is a big no no.
