Having spoken to Samsung UK I went through all the checklist with this fault and only the dreaded factory reset fixed the fault. Now I can plug my phone into my laptop and car usb ports and not get the error. Let's hope it doesn't repeat the fault!
I fixed mine by turning the phone off then taking a the end of a paperclip, with some tissue and jamming it in the port. Push it all around. Turn back on and was good to go. Hope this helps
I had this too, it's a short glitch
Changing chargers fixed it for me
I kept getting it & had to shut off , then restart my tab s3 everytime
Finally figured out my charger was worn out
I solve this issue on my Galaxy s7 Active by wooden stick for teeth cleaning. I cleaned contacts by it in 20 seconds after watching about 15 youtube videos and wasting about 1-2 hours ^^ My experience.
Just to let people know, majority of the time it is dirty charging port unless somone actually got the port wet. BUT there is also a possibility that the charging port has failed, yes, an actual hardware issue. I personally have tried everything from every site I have been to and every video I watched trying to get my Note 9 to charge by cable. The last thing I did a couple weeks back was the dreaded factory reset. I hated to do it but that was the last thing after weeks of trying everything I read and it did not help. My issue is 100% hardware and needs a new charging port which is where the moisture sensor is located. You must try EVERYTHING you can before giving up and having your phone tore apart to be fixed. I opted to use wireless chargers untill I find my next phone, which won't be a Samsung, after owning 7 Samsung phones. I was loyal, Samsung was not...
This happened to me. My phone is 100% dry the charger is what got wet and it seems like its taking a long time to dry. That's what happened. The phones not wet it's the charger.
