Hello after new software update (one ui 4.0) i keep having problem with overheating.My s21 ultra overheat to a point you literally can t hold it and the heating spot is somewhere next to the camera from the back.The overheating issue is happening when i use fb messenger app on video call with 5 G on (and the battery drain faster much more faster ).This is my 2nd S21 ultra as my first device had overheating issue with all apps and was on the older software version.
It is a typical Samsung thing nowadays with Exynos processors mainly. I also had a video call on 4G(not using 5G) and my phone got hot 🔥 in no time. Not a problem on wifi tho. I am also having very low network coverage at home, which contributes additionally. The phone does not overheat while using apps either
Hey try downloading the Good Guardians, there you can control the thermal threshold as this sometimes helps. Also check what kind of app you are running in the background and if there is an application that frequently wakes up without you know. In the Good Guardians you can also see what app is giving you issues
