S21 5g and ui6.1 - no SIM

[UK_Yetirw]

Hi after updating at the weekend to One ui6.1 I have had to factory reset my S21 because the SIM wasn't recognised. Although I now have 4g data etc my SIM still isn't recognised within SIM manager.

Try > 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 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 }
