Since 1 month or more I have problems with my s21. When I plug in my charger, my phone does 2 things:
- Recognise the charger, reboot and then keep charging on and off
- Take several seconds to recognise charger and reboots sometimes, then keep charging on and off
I've changed the charger port + battery, but it's still the same. I'm not sure if these problems started after the latest update or just suddenly. I think it started after the update before the last.
What can it be?
