My iphone 8 just randomly freezes up, overheats, and just overall stops working. It becomes completely unresponsive to the point where i cant open apps, go home, put it to sleep, or turn it off. i talked to apple multiple times and every time they say its fine, but its clearly not fine. is there anything that i could even do for it? is it even worth trying to do something should i just wait for the 12? or get the 11 pro since my phones battery life is already shit. (yes i am an apple sheep i am deep in the ecosystem, and no i do not want an android XD)
