Hi, I have a very similar problem, I just upgraded to Oreo, and the charging is "random". The phone always recognizes the charger but doesn't necessarily charge, any solutions?
Thank you for your asking. Kindly try some stay-at-home troubleshooting tips below:
1. Clean your charge port with compressed air can
2. Please try "the Factory Reset"
Setting>System>Reset>Factory data reset
Please note that once the Factory Reset is completed, all data, apps, settings and personal information will be deleted.
