S21 5G SIM and USB-C not working properly

[jacktjong]

Hi there,

After the last OneUI update, my charging stopped working properly and my data became very slow. After re-seating the flex cables to the usb-c/sim board, the issue persisted. Now, after replacing the board, my SIM isnt being detected at all. Additionally, when I connect my phone to my laptop, it doesnt get recognised as a device.

I've now gone ahead with a factory reset, and the issue still persists.

Should I even try replacing the flex cables at this point, or is it a lost cause?
