I used a similar method of cleaning the gunk of the the port of my phone by using a small paintbrush and rubbing alcohol to sweep the inside of my port. I then used a hairdryer to dry out the port. I took me a few goes, it helps to cup your hand around the port area as you blow dry to direct the air into the port and really dry it out. Finally I restart and it started charging again.
NO OTHER WAY TO REMOVE THIS.
(it's a software issue that samsung have to do something about now before they loose all their client/s like me)
this is the only way I found to get rid of this:
1st. Unplug usb cable.
2nd. Restart your phone.
When you want to charge your device you must:
1st. Connect the "CABLE only" to phone. (make sure your usb cable is not connected to the Charger Head.
2nd. Connect the the usb cable to the Charger Head.
failed to this will surely make that annoying error appear again.
p.s A8+ is my phone by the way. but have the same annoying issue.
Have S8 ACTIVE for almost 7 months with no problems The one that is supposed to be able to get wet and keep on going. Why the heck would I get this notice when I haven't been around any moisture Had a push through update yesterday and now this? What a quick way to get me to leave Samsung again . FIX THIS
I constantly have this message. There has been no exposure to the mositure at all. I think this is a huge glitch! Anyways, the way I get it to charge is this- restart the phone. Once it goes black plug the phone into a charger. When it starts up you should be able to leave it plugged in and charge. You will have to do this every time you unplug the phone. So far this has helped me. Once it is unplugged the mositure notice will still show up.
Alright, I'm getting tired of these antics. I've had an S3, S4, S6 and S8+ and out of 4 phones the newest two go bust after a year or so. I have the moisture Detected error and DEPEND on my phone for work. I've tried shaking it, I blew it out with a can of electronics air duster, deleted the USBsettings data and none of those have worked. This phone has never been in contact with moisture and I am not in a particularly humid climate. My phone got an update about 2 days ago and now this is popping up. I used to swear on the reliability of samsung devices. And at this point I am about to change companies for not only my phone purchases but write the company off of all my technology purchases. Now, I'm not unreasonable, is there an actual fix for this?
