Samsung Galaxy S21 FE 5G / Overheating

[Naurej Alam]

My mobile was working perfectly 3-4 weeks ago but after some OS updates it is getting over heating with single app use like calling, WhatsApp, browsing.

The overheating started within few seconds and it's out of mind.

Earlier I use to used many app together, did trading with 3-4 app continuously but never faced this kind of issue.

The horrifying is that without using any app. It is getting heating in standby also.

Currently weather temperature is about 33 Degree celcious from past few days and in office there is AC at around 22 Degree celcious. In this condition, this is getting heated in standby mode.

Need you help to get it fixed.

Hello 👋 @Naurej Alam 

First turn the phone Off and On i.e a Soft Reboot, but if that does not help then follow this by trying a forced reboot by holding down the volume down key and power button simultaneously for more than 7 seconds to restart it. When your phone resets, you will feel it vibrate.

Sometimes if the phone is misbehaving after an update the following step can help 

• Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port or a usb-c to usb-c phone to phone set up to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

And Https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ can help as a troubleshooting step too. 

In your Device Care there is an optimisation tool which can help. 

And there is a diagnostic tool found in the Samsung Members App. 

May I suggest to perform a forum search as you may find already existing threads with help and advice within. 

If i can be of any further help please don't hesitate to ask  😎
