Moisture detected note 9


Lately I've been getting moisture warning from charging my phone although I haven't been anywhere near water or rain. Only way I could charge my phone was in safe mode anyone else getting this problem I have read note 8 suffered from this problem maybe it needs further investigation.

I forgot to add when turning on the phone and have it boot, leave USB Cable on the phone from the time its starts charging while is off

I was told by tech support THAT SAMSUNG 8 & 9 HAVE SOFTWARE PROBLEMS that they are aware of and didn't notify the public about. What a *****ty thing to do!!!

False, you cannot charge the phone as long as the moisture detector has been triggered whether on or off.

Like i said. If it not because it got wet. Iget constant moisture issues because of weather or cable issue, and my explanation above works every single time.

Over the last 2 days but looks like I've managed to sort it as the cable was faulty

My phone continues to to dhos the moisture detection warning even after it had went away. I have not had any moisture in the phone . I I have kept it in an OtterBox case sent the day I bought it. PleadP let me know how to fix it.



Mine activates for some reason when i leave it charging on the car with usb cable and i shut off the car with the cable still pluged in the phone. I have to take off cable off the phone before turning off the car, if i dont want the warning to come back again.

I had similar issue and I was able to fix it. If you are sure that the surface towards usb c port is not wet, then you can charge the phone. When you charge the phone it will show error message saying disconnect the cable or something. Do not disconnect the cable but restart the phone. Once the phone is restarted the error message will go and the phone will charge normally.

Hope this helps.

I did that and it solved my issue it was strange though

Here is a fix.

1. Turn off phone.

2. Partially  put charging cable in charging port (about 20% in).

3. Start Phone.

4. When Samsung model number appears push in cable 100%.

5. Phone starts charging.

6. Have a sigh of relief.


Basically put cable in when phone has stared to boot.:thumbs-up-sign-emoji-modifier-fitzpatrick-type:
