iPhone 12 Pro Max overheating 🥵

I got my iPhone12 Pro max a month ago and since the very first week using it while purchasing on line, suddenly begun to get really, really hot. I stopped using it and I thought was weird, never thought that would happen again. Well, same situation occurred one time on the second and third week. Last week I found the issue worsen, iPhone 12 Pro Max overheating every other day performing different tasks. I have requested an exchange, they will give a new device next Thursday. Hoping not facing issues again. I’ll keep you posted...
