Another very common problem is the Galaxy S21 overheating when multitasking or downloading files. The problem was suspected to be caused by the device's 5G , but in the end it was ruled out because the problem persisted even after disabling mobile data.
It has been Samsung itself who has decided to put an end to the error by launching an update that resolves device failures such as device overheating. Another solution to the problem is to avoid leaving the mobile charging overnight .
