Could really use some assistance resolving a bizarre issue I'm having with my A3.
My wife and I both bought identical Mi A3s ('Phone 1' and 'Phone 2') and, to take advantage of the fast-charge capacbilities, identical Cygnett PowerPlus 18W chargers (CY3085POPLU, 'Charger 1' and 'Charger 2'). Everything about this setup has worked perfectly on both devices until now.
Yesterday, I accepted the OTA update to Android 10/June security on my phone ('Phone 1'). Ever since, Phone 1 has been unable to charge - upon plugging in the USB-C cable from either Charger 1 or Charger 2, the charging LED light flicks on, I get a notification ping and vibrate, Android flashes up a 'charging slowly' message, then half a second later the phone seems to 'disconnect' from the charging cable only to 'reconnect' again a half-second later, going through all the above again. This carries on endlessly, with Phone 1 sitting there pinging and buzzing away to itself until I remove the cable, never actually charging.
Attempted troubleshooting findings:
Would appreciate any advice on how to resolve this - as far as I can see, the Android 10 update appears to have completely broken USB-C power delivery negotiation on the Mi A3, and I have no idea where to go from here to fix it. Obviously, my wife is very reluctant to apply any updates until this is resolved, which completely defeats the purpose of buying Android One devices.
Any assistance would be gratefully received.
