How To Fix Samsung Galaxy S9 Moisture Detected Error After Getting Wet

Problem: Hi guys I think I have quite a tricky issue going on here – to start off I’ll give you some details that I couldn’t enter below, I live in New Zealand my device is a GS9 , my carrier Vodafone, and I’m having a combination of 2 problems. Firstly the screen has a few cracks which has never been an issue so I’m not too concerned in that respect but I first and most obvious concern is that after being around saltwater some may have potentially splashed some saltwater into the charge port, the phone continued to work flawlessly until I tried to charge it 6 hours later, and not to my surprise “moisture has been detected, unplug charger” fair enough, although I’m assuming it was “dry” by that point after blowing the port out with air not long after it had happened. So consequently I haven’t been able to charge my phone, to the point that the battery is bone dry. I looked up some fixes to bypass the moisture detection issue, and found clearing the USB settings cache. But as my phone is dead I’m unable to access that setting, this issue in mind I also heard of a tip to enter into “recovery mode”, then plug the phone in to allow trickle charge, wait an hour, power on and access settings with limited battery. And therein lies the other issue, I cannot enter recovery mode for the life of me! I have tried many different combinations and have only been able to access the custom operating system menu. No logo upon trying combination of vol up + Bixby button then power. Or any other signs of life besides custom OS menu. So I’m not sure if it needs some power to enter recovery, OR WHAT!? Note: I did accidentally enter the Odin custom OS menu first, before using the correct combination of buttons, and it was momentarily “downloading” until I canceled by holding same buttons again. P.s. now no menus appear and it seems to have become a paper weight. What are my options? Cheers for your time, I know this is a long winded one.

Solution: The first thing you will want to do in this particular case is to make sure that the phone is dry. Wipe the exterior part of the device with a microfiber cloth. Make sure that the charging port of the phone is free from moisture by leaving the device in a cool place for at least 2 hours. Any moisture present in the port will evaporate naturally. You can also speed up this process by using a mini vacuum or a hair dryer on the port.

In case water has entered the phone from the crack in your screen the you will want to make sure that the internal parts of the phone is dry. You can place the device (turned off) in a bag of silica gel for at least 48 hours. The silica gel will absorb the moisture inside the phone. As an alternative to silica gel you can also use uncooked rice.

Once the phone is completely dry it’s time to charge the device by following the steps listed below.

Clean the charging port of the phone

If the charging port of the phone has dirt or debris in it then this could cause charging problems. It is recommended that you clean the charging port using a can of compressed air. This should remove any particles stuck in the port.

Try using a different charging cord and wall charger

To eliminate the possibility of the charger causing this problem it is best to use a different charging cord and wall charger to charge the phone. You should also consider using a wireless charger.

Perform a factory reset

One last troubleshooting step to consider is a factory reset. This will revert the phone back to its original factory condition. Make sure to backup your phone data before performing this step.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.

Once the reset is complete charge the phone fro at least 20 minutes before turning it on.

In case the above steps fails to fix the problem then it’s very likely this is already caused by a faulty hardware component. I suggest that you bring this device to a service center and have it repaired.
