How to Fix Samsung Galaxy Note 8 That Keeps Showing “Moisture Detected Warning”

Step 1. Clean charging port/USB

You need to take a small piece of tissue paper and clean the port gently. Make sure the tissue remains in contact with the port at least for a minute. This lets it absorbs the moisture from there. Repeat this procedure 2-3 times with an unused tissue paper every time. Make a blow into the port to eliminate any dust or other elements present over there.

Step 2. Perform a general inspection on charger and the cable

The problem can be due to the failure of charger or defect in the cable. There are chances that they can have moisture in them and the phone is refusing to charge because of no other reason than this. Because the port of the charger is having larger size then that of the phone, you can clean it easily with the tissue paper in a similar manner. However, I would again like to inform you to be gentle in order to avoid any issue. You can even make sure of alcohol to clean the same. There is no need to worry as the alcohol dry out too quickly.

Step 3. Make sure the problem is not due to the liquid damage

There are chances that moisture reaches some components inside the device and has already caused the damage. Thus, you need to check the liquid damage indicator. For this, simply follow the below steps.

• First of all, remove the SIM card tray from your Samsung Galaxy Note 8.
• Look into the SIM slot to find a small sticker
• If it is of white color, your Galaxy Note 8 is safe. However, if the color is Red, it’s a clear indication that it has liquid damage.

Step 4. Ignore the warning

You can do this only if you are sure that the charging ports are clean and there is no liquid damage. You can charge your device by ignoring the warning message and steps for this are listed below.

• First of all, plug the charger into a wall outlet
• Connect the cable to your device
• You will see a warning message on the screen. Ignore it and restart the device. Keep the charging ON.
• Your Samsung Galaxy Note 8 will keep charging them without showing any warning message after the restart.

In case you didn’t find it working, go to the next step.

Step 5. Charge your device in Safe Mode

In safe mode, the Galaxy Note 8 doesn’t give any warning and will thus continue to charge.

Step 5: Try charging your Note8 in Safe mode

It turns out the service that handles the warning isn’t running when the phone is in safe mode so you can actually continue charging while in this environment. I would like to mention it again that there should be no liquid damage in your device before you proceed with further information. The steps to take your device in the safe mode are:

• Turn OFF your Samsung Galaxy Note 8 and press and hold the Power key

• Release the power button when you see “SAMSUNG” appears on the screen.
• Next is to immediately release the Power key, press and hold the Volume down key.
• Safe mode will display in the bottom left corner of the screen. Release the volume down button when the same appears on the screen.

Let the device charge fully when it’s in safe mode. Once charged take a back-up of all the data and reboot your Galaxy Note 8 into normal mode again. Probably the message will be gone. In case it’s not, next step is to perform a reset.

1. Turn off your device and press & hold the Volume Up key and the Bixby key, then press and hold the Power key.
2. 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).
3. Press the Volume down key several times to highlight “wipe data/factory reset.
4. Press Power button to select.
