Please help me
My phone is s21fe, after updating my phone to the latest version of Android, some parts of the phone have stopped working and the phone has a bug.
otg doesn't work, wired handsfree doesn't work, reverse charger doesn't work, charging speed with QC went from 9.3V 1.6A to 9.3V .83A.
I also did some of the solutions that were mentioned on the internet, including usb debugging and...
But it didn't work.
Please guide me, what should I do?
