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

What you need are practical troubleshooting procedures to get rid of the error and make your phone charge again.

First solution: Try doing the forced restart first

I have encountered a similar issue in the past wherein it was caused by a pretty minor glitch in the system. How did I know? Well, what I did was to perform the forced restart, or the simulated battery removal. It reboots the phone and refreshes its memory, as well as reload all services including the one that handles the charging process. Here’s how it’s done: 

  1. Press and hold the Volume Down button and don’t release it yet. 
  2. While holding down the volume button, press and hold the Power key as well. 
  3. Keep both keys held down together for 15 seconds or until the Galaxy A20 logo shows on the screen.

Once the phone has finished rebooting, try to see if your phone still shows the ‘moisture detected’ error when connected to the charger. If it does, then try the next method.

Second solution: Clean the charging port

The ‘moisture detected’ error is often triggered by a wet charging port and if the first solution failed to fix the problem, then you will have to manually clean the port. The Galaxy A20 has a Type-C port, which is a bit bigger than the previous technology. What you need to do is get a small piece of tissue paper that can fit into the port, and then insert it gently into it. Leave the tissue in the port for 10 minutes or so. It is best to just turn the phone off while waiting for the port to dry out. 

The troubleshooting of this problem can reach up to 24 hours depending on how much liquid got into the port. If the phone got submerged in water, then the port should be really wet. But don’t worry, the tissue will absorb the moisture. 

After 10 minutes of having that tissue in the port, turn the phone on and then try to reconnect it to its charger to see if the problem is fixed.

Third solution: Clean the cable

This is often the most overlooked step. We often think that when the ‘moisture detected’ error shows, the moisture is only suspended in the charging port of the phone. Well, the end of the cable that  you connect to your device can also be wet. 

Using an anti-static brush, or clean and dry toothbrush, gently brush the connector and until you’re satisfied that it’s clean and dry. Or, if you knew that it also got soaked in water or any liquid, wrap it up with a piece of tissue paper and leave it like that for several minutes. 

If you think the charging port and the cable are both dry, try charging your phone and see if the ‘moisture detected’ error still shows. If it does, then move on to the next solution.

Fourth solution: Reset your phone, if possible to eliminate moisture detected error.

There was a time when Galaxy S9 owners were also bugged by this problem and the cause was an update. In other words, it’s always possible that the ‘moisture detected’ error can be caused by a firmware issue. To rule this possibility out, and probably before you seek help from a tech, try to reset your phone. This does not only rule out the possibility of a firmware issue, but also clears all your personal information and data from your phone. So, if you still have enough battery in your phone, backup your files and data and then follow these steps to reset your phone: 

  1. Turn off the device.
  2. Press and hold the Volume Up and Power keys.
  3. When the Galaxy A20 logo shows, release all three keys.
  4. Your Galaxy A20 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If the problem continues after the reset, then bring the phone to a local shop and have the tech fix the issue for you.
