You could try sending an error report within this members app.

Do you multitask with your device such as calling whilst browsing or charging your device whilst using it? These processes take up CPU in the device and can cause the device to heat, which can be normal in some cases. However you should be able to minimize overheating by making some changes to the phone.
If the phone is overheating whilst being used then the first thing you should do is stop any apps that might be running in the background [recent applications (left navigation key/icon)>close all].
It is also a good idea to use device maintenance to optimize the phones settings [settings > device care >optimize now > done > battery/performance mode > storage > memory > device security].
As overheating can be due to active apps using the data connection (mobile data or Wi-Fi), you can also turn on data saver in the phones settings [settings > connections > data usage > data saver > toggle: on] and you can also allow unrestricted data usage for particular apps in this menu.
Please also refrain from using the phone whilst it is charging or leaving it exposed to external heat sources. To cool an overheating phone down, please temporarily remove any covers or cases that are protecting it – you can put these back on once temperature has reduced.
If you have tried these, and the issue persists, I suggest sending through an error report for this to be investigated further.

I randomly get over-heating, it happend a few nights ago, I thought it might of been charging while been on my phone (not to long of a use) quickly check my messages. When it started to happen, I unplugged, held it up to my fan, still no changed so decided to turn phone off/On which seemed to fix heating. A bit of a worry 😔 as I'll be giving this phone to either to one of my siblings or Mum when I get the S22 Ultra when it comes out. I don't want the to think I'm playing a prank on them when they burn there hand or face when on a call when it decides to over-heat.
