I was using a Samsung car charger with a USB-C to C cable and was able to fast charge with it for about 6 months when it suddenly stopped working. What's even more strange is super-fast charging still works. I thought it was the AC adapter so I purchased a new one from Anker. I am able to achieve super-fast charging 2.0 using that, but still can't fast charge. USB-A to C still works for fast charge. I have tried wiping cache partition, and booting in safe mode. I tried swapping out cables and AC adapters. Nothing is working.
