If you have tried charging your Samsung Galaxy S7 after submerging it in water, you might have gotten the following warning “Moisture Detected”, with the phone failing to charge. If it has happened to you, and it probably has since you searched for this problem, do not worry. It is not a bug or a real ‘problem’. It is a software feature implemented by Samsung.
Unlike the Galaxy S5 which protected the charging port with a rubber cover, the Galaxy S7 has no outer protection. The phone is sealed from the inside which means when submerged, the water does go into the charging port. It just doesn’t go any further into the phone’s internal components.
Why and when does it show “Moisture Detected”?
Now, if you have just come from a swimming session with your phone, you won’t be able to charge it. The Galaxy S7 and S7 edge have a kill switch which disables the charging capability if there is any water or moisture inside the charging port. Because if there is anything inside the port and you attempt to charge the phone, it might short out and completely destroy the phone. That is why Samsung has implemented this feature. Every time there is water or something else inside the charging port, the warning “Moisture Detected” error will show up to prevent your phone from getting destroyed.
How to fix this error?
As you saw above, the reason why this error shows up is because of moisture inside the charging port. If the phone is wet, wipe it with a clean cloth and then shake it with the charging port facing the ground to remove any excess water.
Then, take your hair dryer and dry the phone for a couple of minutes. Keep checking your phone because it shouldn’t get too hot. Then, take a small piece of cloth and try wiping any possible water or moisture left. Then reboot your phone and you should be able to charge your phone without any problems. This is one of the most common ways to fix the “Moisture detected inside the charging port” error on the Galaxy S7 and Galaxy S7 edge.
