I posted several months ago on having this issue on my Note9. I had it (the problem/error) for months and just used wireless charging to get by. I consulted with an official Samsung repair center and they wanted to charge me to tear apart my phone and replace the charging port where the moisture sensor is located because it has failed. I couldn't get them to give me a straight answer on whether the repair would void me trading in my phone down the road since I'm in the jump program. So I opted not to do it. Thank God I didn't pay them. Some time in June (13th or 14th) I got an update, security and bug fixes, and my phone then magically started charging one again and the error messages had disappeared. I did everything that you can find online to fix the problem prior to this and had given up weeks before this update. I feel bad that some people actually paid to have the port replaced when it ended up being a software issue. Even T- mobile wanted me to turn in my phone to get a new one after we hard reset it and it didn't help. Im so glad I have good gut instincts. No need to get a new phone, tear it apart to replace parts or even the dreaded factory reset because it magically fixes itself after an update. Go figure....Good luck folks!
