Bro, see if any recently installed apps are causing this issue..for this you have to run your phone in the safe mode..and also if temperature in your city is high, then it's normal.. If it's not unbearable, then you should not worry.. If you are using armoured case, then remove it for a while.. Also, you can change your device display resolution to fhd+... Restrict background data usage Put apps to immediate sleep mode when they are not in use Keep your device brightness in between 40-50%.. If Fast charging is not required then try normal cable charging.. Scan your phone.. Restart your device once or twice in a week.. Try these basic steps and check..
Happens to me also and because of this the CPU start to throttle and I couldn't get the best performance from this phone while gaming and while rendering videos on premier rush.
With basic usage also this phone starts heating don't know why but the heating is more on the exynos version, Did some research and got to know that the battery life and performance is better on the Snapdragon version.
