I live in south Florida for the past 30 years and have always had Galaxy cels since probably the S2 if I remember correctly. I purchased directly from Samsung 1-1/2 years ago a S10e. My wife is an Iphone user for the longest time. All that being said, we never ever had any such issues till last week when I had exactly the same error message and the same result from a tech recommending to go to Ubreakifix and same.response by the employee. Leave it and we'll see what we can do but outright stating it is out of warranty and possibly the port which is sauntered to motherboard will need to be changed at a cost of over $300.00. Definitely did not leave it. Called Samsung Tech support and explained the whole situation. They were very friendly and kind and stated they would repair this one time free of charge. Cel went and back within 10 days. Repaired and working perfectly. After I had done all my setup and put it back to all.my settings, etc., called tech support to find out what was wrong explaining again I do not place my cell near water and have been doing same charging procedure for many years and never had the issue. 2 things the tech told me. 1) Try and always use charge cables designed for unit and not cheap ones which do not have the required standards and electronic chips in charge ends. 2) Try to not overcharge by charging prior to going to sleep. Instead do it while awake and disconnect as soon as it shows 100%. Not sure about this last one since new wall adapters have the electronics to shutdown at around 95% and then trickle charge.
I have today ordered 2 new charge cables thry Amazon which are quick charge 3.0, braided, S10e compatible, 12,000 bends tested, and more. Rampow brand because I needed short cables for the car. I have longer cables at home Aukey brand which are excellent.
Hope this clears it for the so many with same issue.

For the person that stated to use wireless charger, this will not work since the charge port and the wireless internal are tied together to mother board. When one goes, so does the other one as explained by employee from Ubreakifix.
@casketdriver, @userruPfMUHdzE, @user7qYAwbcy8z @my wife's S20 started with tge moisture detected about 3 week ago, just after completing tge Aug 1 software update. Is it the update? I'll find out soon as i am downloading it as I bounce between wifi networks.
Ubreakifix is giving you false info on the no wireless charging if there's moisture detected. She bought the Anker 10w Max wireless fast-charging pad and it works great.
This seems as if its a common issue for the S20, Samsung uses its IP68 rating tauting water resistance up to 1.5m for a 30 minute duration as a selling point. Random moisture and humidity should not cause this.
My moisture error started after an update last week, maybe the update made sensor more sensitive.
I was able to charge sometimes with phone turned off. Humidity did seem to worsen this moisture warning problem on my phone, here in SW Florida humidity is extreme. I flatened the end of a tooth pick to make it soft like a brush, moistened that with 90% isopropyl alcohol, used that to clean lent and debris from charging port, blasted port with canned air (dust off) and no more moisture error. It might be necessary to clean the connector on the cable as well. I think the lent and debris was shorting the connectors when damp from humidity. Last resort might be a wireless charger, that also worked for me. Good luck!
