my device overheats without any need and then it works normally as well. For the first 30 minutes it was very hot when I first turned it on. it is also always hot while charging.
Mine has started overheating, to the point where I can't even hold it. Also when I try to use the camera my phone will freeze for 10+ minutes. Finally, the UI will lag sometimes too
I have had the same issue with my galaxy s10 for weeks. It would get really hot and start freezing. I discovered by taking and leaving my phone out to the case it solved the problem, no more over heating or freezing for well over a week now
What about if you're not using a case? My phone at this moment is so hot it actually hurts to hold, so it's bareback on the couch. It gets this hot when I'm surfing the internet for more than a few minutes.
