Download 360 security from play store the company is quho or something like that..it has a phone cooling feature and also boosts phone,i use it on my s8+ and love that it notifies you when its overheating
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.
