My S9 was plugged in the other day, went to use it and no response. Black screen and blue notification light still blinking. The phone was at about 90% battery. I have tried all the fixes from online sources (soft restart, hard restart, volume up + power + bixby, etc etc) and nothing is working. I have tried plugging it into the charger. I have tried connecting it to my laptop... nothing. Anyone have any other ideas?
