So last night I got home after my battery had died and plugged my phone into the OEM fast charger. Once the phone booted up I noticed that I would constantly see the "fast charging" indicator pop up on and off. The phone was charging but it seemed pretty odd. I noticed that when the indicator would flash a brief white box as if it is trying to tell me something about the charging connection briefly flashed. Upon further troubleshooting I booted into safe mode and the problem stopped. I booted back into the regular enviorment and the problem started again but this time less frequently. I have a hunch this might be an OS bug and before I wipe and reformat I wanted to glean out from past experiences. Thank you community!
