So i woke up to no form of adaptable c type usb charger working in my port at all, chargers tested and work ok on s8, it will wirelessly charge but thats a ball ache as my phone is my sat nav and I don't want to have to buy wireless chargers everywhere.
Let's try a soft reset on the phone. This will end all processes and give the phone a fresh start. To do this, press and hold the 'Power' and 'Volume Down' buttons until the phone restarts. Let us know how you get on.
