The Go To Solution did not work for me. I have a Note 10 Plus, less than a year old. I first checked the port for moisture. Dry as a bone. I powered the phone off and cleaned the port with denatured alcohol and cleaning cloth anyway and made sure to get both sides of the pins. Dried the area thoroughly. Powered back on, still received the moisture alert. Tried a different Samsung charger, different Samsung cable, same error. I tried Safe mode. Alert still appears so it is not being caused by a 3rd party app. Wiped cache, as instructed in the Go To Solution, restarted, still have the moisture alert icon. A suggestion from a Youtube video said to try this. Go to Settings/Apps/System Apps/ USBSettings/Storage and cleared Cache and Data, restarted and the alert still appeared. I don't want to do a factory reset yet. I guess I'll have to take it in for repair to UBREAKIFIX location. The new iPhone 12 Max is looking better and better.
