S21 Overheating - Samsung "unaware" of any issue.

I have cumulatively spent multiple hours dealing with over heating issues on the new Samsung Galaxy S21 5G (recieved on the 28th of January 2021).

I primarly use my phone for video calling and have found the device to heat up uncomfortably and crash multi-windows, after only 10 minutes of use.

I only ever have a couple of applications open. My brightness has been below 20%. It has been out of direct sunlight. It has had the latest software updates. I have reset all of my settings, and performed "soft resets".

Samsung has suggested the issue is with 3rd party apps (WhatsApp and Facebook), and recommended that I exchange my phone case to their £50 ones on their website (despite not being able to explain why their case was better than my current one). Howver, the issue is also prevelant without the case.

They have claimed that they are "unaware" of any similar overheating issues, despite multiple posts on the Samsung Community that seem to illustrate the contrary. I have also been left hanging by customer service by almost a week and had to prompt them multiple times.

this is what is happening to my device, except i am video calling instead of playing videos. https://youtu.be/Hrq62ni9cWo



have sent for a replacement.

Hi there!

I had all the same problems as you with my new S21.  My s21 would heat up no matter what even when I was doing the same things as I would on my old S8, which would not heat up at all. I tried doing everything but my phone was still heating up until I tried to turn off 5G (Notifications panel > power saving mode settings > Turn off 5G). After I turned it off, my phone stopped heating up to dangerously high temperatures. I suggest you try to turn off 5G and see how it goes (I know its sucks when 5G is in the name of the phone...lol) All the best!

First one I used smart switch, 2nd one I did not. Factory reset First one it did not resolve the overheating and poor battery. 2nd phone same. I have had to set up my phone 3 times. Still having issues. Samsung does not care. I can not go another 2 weeks with out my phone. Sadly I will be trashing this one and purchasing a Google phone
