Whatever the update I got on June 14 fixed mine. I had the one UI 2.0 already, there was just some security & bug fix update. Right after that update the notification was gone and I can charge with my cable once again. I had the error message for months, tried everything you can find here to try to fix it and even had my phone diagnosed as needed a new charge port (that I didn't follow through with). I feel bad for those that went through with the port replacement and some paid money of of their pocket. I always charged wirelessly so It wasn't a huge bother, just bugged me that I couldn't connect my phone to my computer through the cable. Either way, it's magically fixed!
