I'm facing an issue with my Samsung S21 where it's not engaging fast charging or ultra-fast charging. Initially, a few weeks back, it would switch to super-fast charging when I flipped the charger's port, but suddenly, it's only doing regular charging since yesterday. I'm using original Samsung charger and wire. Interestingly, I've found a workaround where if I restart my phone and immediately plug in the charger upon boot-up, it shows the ultra-fast charging sign. However, if I unplug and reconnect the charger, it goes back to simple charging mode. Any suggestions or solutions would be greatly appreciated!
