Overheating and a lot of lag

Whenever i try to play minecraft my phone overheats a lot. It becomes so hot at the point i am worried about it. This didn't happened before. This started after i updated to 1.19. This happens everytime i open minecraft. Even if the worlds is superflat or just started my phone gets hot.i  maybe its because its summer and its much hotter but i have seen that on most of other games it doesnt heat that much. 

Also when i am on a cave in a mode that spawns hostile mobs and sometimes even on the surface my game lags so bad

 

I have a render distance of 8 and simulation distance of 4

My phone is a galaxy A12, 128gb storage and 4 gb ram.

Thank for your support
