Fix: ‘Moisture Detected’ Message won’t Go Away in Galaxy S8

Along with many other features that the S8 possesses, it comes with an IP68 Water resistant rating. The IP68 rating on the phone means that it can handle to be in 1.5m of water for a period of 30 minutes with no side effects. However, recently there have been many reports of the “Moisture Detected Can’t Charge” error which can be seen on many devices which were not even submerged in water at any point in time. This message doesn’t go away even after rebooting the phone or trying to air dry it.

What Causes the “Moisture Detected Can’t Charge” message on S8?

After receiving numerous reports from multiple users we decided to investigate the error and devised a set of solutions which eradicated the error for most of our users. Also, we looked into the reasons due to which this error is triggered and they are listed below.

  • Cache: All applications store cache to decrease loading times and to provide a smoother experience to users. Over time this cache might get corrupted and start interfering with important elements of system applications. In some cases, this cache might be triggering the moisture sensors installed in the charging ports and preventing them from working properly.
  • Software Issue: This issue was observed on some devices only after an Android update was installed on their device. It is possible that the update contained a bug which caused the moisture sensors to glitch out and stopped them from working efficiently.
  • Hardware Issue: It is also possible that the charging port might have been damaged due to high voltage or an electric surge due to which they might not be working properly.
  • Third-Party Applications: Sometimes, third-party applications might malfunction and interfere with important system functions one of them being the charging feature. The Moisture sensors in the charging port can often be interrupted by these applications due to which this error is seen.
  • Salt Water: The message can sometimes be persistent if the phone was submerged in saltwater. This is because the IP68 rating does not apply to saltwater.
  • Wet Port: If the charging port of the mobile phone is wet or has retained some moisture the “moisture detected” message will not go away unless you get rid of it.

Now that you have a basic understanding of the nature of the problem we will move on towards the solutions. Make sure to implement these solutions in the specific order in which they are provided to avoid any conflicts.

Solution 1: Checking for Moisture

If the phone was submerged in normal or saltwater at some point in time then the error can be persistent unless the charging port is cleaned. It is recommended that you try to vacuum (not blow dry!) the phone’s charging port and if trying the solutions below don’t fix your problem, take it to the local Samsung Customer Care center for service.

Solution 2: Checking For Software Updates

In some cases, it was seen that the problem was caused due to a system update. Developers often provide fixes in such cases therefore, in this step, we will be checking to see if an update to the software is available. For that:

  1. Drag down the notifications panel and tap on the “Settings” icon.

  10. If the issue doesn’t go away continue to delete applications until it does and boot out of safe mode after fixing the error message.

Solution 4: Deleting USB Cache

Over time cache can be corrupted and it might cause issues with important system functions. Therefore, in this step, we will be clearing the cache from USB Settings. For that:

  1. Pull down the notifications panel and tap on the “Settings” icon.

  6. Now restart the phone, try to charge it and check to see if the issue persists.

Solution 5: Wiping Cache Partition

If the cache of any system application or third-party application is corrupted then the phone might face issues while trying to charge. Therefore, in this step, we will be wiping the cache partition. For that:

  1. Press and hold the “power” button and tap on the “Switch off” option.
