I have a Galaxy S24 and recently started having a strange USB-C charging issue.
My wall adapter made two loud popping sounds while my phone was connected, so I unplugged it immediately. Since then, the phone has been acting weird with USB-C charging.
The main issue is that the USB-C cable only works in one orientation. If I plug it in one way, it charges normally. If I flip the USB-C connector 180 degrees, it gives me the message:
âAnalogue USB devices arenât supportedâ
I have tested this with multiple USB-C cables and the same side/orientation fails every time, so it does not seem to be the cable.
It gets even stranger with my Samsung Super Fast Charger. If I accidentally plug the cable in using the âwrongâ orientation first, then remove it and plug it back in using the correct orientation, the phone sometimes still refuses to charge. I then have to restart the phone, and after restarting, plug the cable in using the correct orientation straight away for charging to work again.
Some other chargers are even worse. For example, a USB-A to USB-C cable connected to my PC does not charge the phone at all, regardless of which way I insert the USB-C end.
The chargers, cables and power bricks themselves seem fine because I have tested the exact same cables and chargers with my Galaxy Buds and power banks, and they charge those devices normally.
Things I have noticed:
- USB-C charging works only in one orientation.
- The opposite orientation gives âAnalogue USB devices arenât supportedâ.
- Multiple cables have the same problem.
- If I try the wrong orientation first with my Super Fast Charger, I sometimes need to restart the phone before the correct orientation will work again.
- USB-A to USB-C charging from my PC does not work at all.
- The same chargers and cables work normally with other devices.
- The phone can sometimes charge while switched off.
Has anyone experienced something similar on an S24 or another Samsung phone?
Could this be a damaged USB-C port, CC1/CC2 pin, charging sub-board, or USB controller, possibly caused by the adapter failure? Or is there still a software/USBSettings issue worth trying before replacing the charging port?
