S9+ Does Not Fast Charge

Problem: I am using s9 plus and got error moisture detected in USB port. I was nowhere near water and not sure why that notification popped up. I tried all troubleshooting steps mentioned on your website. Except factory reset as battery died by that time. Went to Samsung service centre and they did the factory reset by while charging wireless. After that the error did not came back but my phone stopped detecting fast charging. I again tried the troubleshooting steps mentioned on your site. Is there a possibility that the guys at service centre might have tried to physically open the port as they took the phone inside for 10 min and was out of my sight. I called them and they said they’ll have to probably repair the USB port. My phone is just 3 weeks old and I am worried if a phone is opened so early in its life may affect its performance in long run. Please let me know what would be your recommendation.

Solution: It appears that the problem is already caused by a faulty charging port assembly which will need to be repaired at a service center. There are however some troubleshooting steps that you can do which we have listed below before bringing your phone for repair.

  • Clean the charging port of the phone using a can of compressed air. Make sure to remove any dirt or debris stuck in the port.
  • Try using a different charging cord and wall charger to charge the phone.
  • To eliminate any software related glitches that could be causing the problem you should try to do a factory reset. Make sure to backup your phone data  before doing the reset.

If the above steps fails to fix the problem then you will most likely need to have the charging port assembly of the phone replaced at a service center.

S9+ Keeps Getting Moisture Has Been Detected Error

Problem: My S9+ keeps getting the water has been detected message. My phone was not exposed to water. The error appears after my charging cable gets disconnected from power. Like if I’m driving in my car with my phone plugged in then I turn the car off the water has been detected message comes up and doesn’t go away. Same thing if I’m at home and my wall charger is unplugged. I’ve tried shutting the phone down all the way but the message only goes away whenever it feels like going away. I even did a update today and the message still appeared after the update was finished.

Solution: The first thing you will need to do in this case is to eliminate the possibility that some moisture is present in the charging port of the phone. You can use a mini vacuum or a hair dryer to remove any presence of moisture in the phone charging port. Alternatively, you can leave the phone for 2 to 3 hours which is enough time for the moisture to naturally evaporate.

In case the issue persists then try to check if this is caused by a software glitch by doing a factory reset. Make sure to backup your phone data before doing the reset.

If the above steps fails to fix the problem then you should have your phone checked at a service center.

S9+ Gets Hot When Connected To Charger

Problem: My son has a Samsung Galaxy S9+ (I’m unsure about the OS version) which he’s been having problems charging off and on for several months. It’s now reached the point where it doesn’t charge at all. I did a soft reset then   tried charging , it started off at 1 %. I thought, great it’s working. So I left it for a half hour or so and came back to check. It then read 0% and the phone was very hot. I immediately unplugged it. I figured the problem was likely with the USB charging port. I cleaned it making sure that no dirt is trapped inside. But the phone still doesn’t charge at all. I’m wondering if the phone might need a new battery?  Do you think I should have the battery replaced? Or is there another way to try and revive the phone or otherwise retrieve the contacts? I appreciate any advice or direction you can give. Thanks

Solution: If the charging port of the phone is already free from any dirt or debris then you should try using a different charging cord and wall charger to charge the phone to eliminate the possibility of the problem being caused by the charger. In case the issue still persists then you should bring this to a service center and have it checked as it is most likely already caused by a faulty hardware component.

S9+ Not Turning On After Drop

Problem: I dropped my phone at the airport yesterday and it just totally stopped working.  It will not come on, will not charge, basically it died. There are no cracks in the screen or anything like that.  It is in a leather case, but fell face down on the pavement. What could that be?? Please tell me my phone is not trash and can be fixed.

Solution: Did your phone have sufficient battery charge before you dropped it? If not then charge the phone first for at least 20 minutes then do a soft reset. This is done by pressing and holding both power and volume down buttons for at least 10 seconds. Your phone should restart after this.

In case the phone does not turn on then you should have this checked at a service center.
