Samsung Galaxy A20 won’t charge, keeps showing ‘moisture detected’


If your Samsung Galaxy A20 displays the ‘moisture detected error’, it won’t charge. This is how the phone reacts to prevent liquid damage. Even-though the phone doesn’t have the IP68 certification its’ protection is satisfactory. The error of ‘moisture detected’ shows up when moisture detected in the charging port by the device itself.

Don’t bother, there are plenty of solutions for you. Most of them are not complicated at all. You will be able to perform them just after reading this. I’ll provide them to you in this post. So, all Samsung Galaxy A20 users, keep reading!

If the error keeps showing up most of the time there is some moisture in the charging port. So with keeping that in mind, let’s move on to the available solutions for your issue. 🙂 

Method 01: Try forced restarting the phone

I have had the similar issue several months ago due to a very small glitch in the system. You might be wondering now how I know that was due to a minor glitch. I only did performing the forced restart or simulated removal of the battery. That process reloads all the functions including the charging process. Only you have to do is to follow the steps.

  1. Press and hold the ‘Volume down’ button
  2. While holding it, press and hold the ‘Power’ key also
  3. Keep both keys holding until the Galaxy A20 logo shows up

Try charging your phone once the rebooting is finished. And see whether it still shows the ‘Moisture detected’ error. if it is still there, try our next solution.


Method 02: Clean the charging port

As I have mentioned earlier, most of the time the error is due to wet charging port. So, you may need to clean the port. Galaxy A20 has a bigger Type C port. You can clean the port using a clean dry tissue paper which can fit to the port. First turn off the phone. Insert the paper to the port carefully. Leave the paper in the port for about 10 minutes to dry up.

Turn on the phone after 10 minutes and try charging it to see whether the problem is gone or not. Please note that the troubleshooting time depends on how much moisture is there in the port.

Method 03: Clean the cable

This is always ignored as we only think that the moisture will be collected in the charging port. The end of the cable which you connect to the phone may get wet too. You can use an anti-static brush or even an clean dry toothbrush. Carefully wipe the connector till you are happy. Or you can wrap the connector with a clean dry tissue paper for about 10 minutes. Try charging the phone when you think it is try and look for the ‘Moisture Detected’ error.

Method 04: Reset your phone, if possible

Earlier Samsung Galaxy S9 users had a similar issue and that was due to update. So, there is a possibility that this error might caused by a firmware problem. To confirm that you can try resetting your phone before going for tech support. As this clears all of your data we would recommend you to backup the data before performing this. Follow these steps, once the back up finished.

  1. Turn off the phone
  2. Then Press and hold both the ‘Volume Up’ and ‘Power’ keys
  3. Release all keys once the Galaxy A20 logo appears
  4. Wait till you see a black screen with blue and yellow texts
  5. After that Navigate to ‘Wipe data/Factory Reset’ using the ‘Volume Down’ key
  6. Press ‘Power’ key to select
  7. Then highlight ‘Yes’ using the ‘Volume Down’ key
  8. Press ‘Power’ button to select
  9. Then, highlight ‘Reboot System Now’
  10. Press the ‘Power’ key to restart the phone

If the problem is still there we would recommend you to go for the tech support.
