S9 Moisture Detected Error After Software Update

Problem: I have a Samsung S9 and I have been using it for about 2 months I don’t believe in phone being waterproof so I try not to get my phone wet. But for some weird reason after my phone got updated to a newer version I start getting the msg “moisture detected” I watched some YouTube videos and did has inform the cleaning port with cotton, nothing happens, using a different charger it started working for a while but then the msg reappear… I did the clear usb cache in the apps setting that didn’t work I also tried to factory reset my phone but then the new update was still on the phone and kept getting the error msg.. From time to time I turn off the phone and I realise it charges and other times it dont I would just put in on the charger and just leave it and after several minutes of hearing the beeping sound “moisture detected” may flashed on the screen after a while it just stops and charge… After doing several resource I found a video that told me to trying charging the phone in safe mode and I tried that and it works I haven’t got the msg in a while…. but the thing with safe mode I can’t get any calls, msg nothing… What should i do.

Solution: When you get this particular error message on your phone the first thing that you need to do in this case is to make sure that the charging port of the phone is dry. Use a mini vacuum or a hair dryer to remove any presence of moisture in the charging port. If it is already dry and the issue still occurs then you will have to backup your phone data then start the phone in recovery mode. From here you should wipe the cache partition of the phone then follow this up with a factory reset.

If the above steps fails to fix the problem then you will have to bring the phone to a service center and have it checked.

S9 Turns Off After Showing Samsung Logo

Problem: Hey there! My device got switched off and then i connected it to my charger. It was successfully charged upto 82% and when i switched it on..the samsung logo show on the screen but suddenly after that again my phone turned off. Since few days one notification displays on the screen that “process system is not responding… you want to close it?” And then i used press the ok button. But now i was trying since last night to turn on the phone but it doesn’t turn on. The problem is that my phone gets off just as it starts. Although battery is 88% now. I tried the above booting processes also but still the same is happening with the device. Please help me

Solution: The best way to fix this problem is to first remove the microSD card of the phone ( if you have one installed) then try starting the device in Safe Mode. If you can start the phone in this mode without experiencing any issues then the problem is most likely caused by an app you downloaded. Find out what app this is and uninstall it. In case the issue still occurs in this mode then you should do a factory reset in recovery mode to eliminate the possibility of the problem being caused by a software glitch. Take note that this will erase your phone data.

If the above steps fails to fix the problem then you will have to bring the phone to a service center and have it checked.

S9 Not Responding After Drop

Problem: hi, today my samsung S9 fell down from an height of 2 to 3 feet. it doesn’t have any scratches or crack or damage but  it stop working i had tried to put it on charge but its not charging. there is no response from the device even after pressing all the keys. may i know what would be the problem and please help to resolve it. thank you for the help.

Solution: It’s very likely that the problem is caused by a hardware component that got damaged by the drop. What you will need to do right now is to try to charge the phone for 20 minutes with a wall charger. This way you can check if the issue is simply caused by a drained battery. Once the battery has sufficient charge try turning on the phone by pressing and holding both power and volume down buttons. If the issue persists then you will have to bring the phone to a service center and have it checked.

S9 Fast Charging Not Working

Problem: Fast charging not working. if I use the charger and cable for my S9, works fine, car charger, fine, power bank…starts out fast charging and within 15 sec switches to regular charging. Cable and power bank worked fine with my phone. Tried all steps outlined above except factory reset, this is a new phone!!

Solution: The first thing that you will want to do in this case is to make sure that the fast charging setting of the phone in enabled.

  • Open Settings app.
  • Tap Device maintenance.
  • Tap Battery.
  • Tap More options at the upper right (three-dot icon).
  • Tap Advanced settings.
  • To turn on Fast cable charging, touch the slider.

If it is already on and the issue still persists then proceed with the additional steps listed below.

  • Try charging the phone when you are not using it and make sure that the screen is off.
  • Try using a different Samsung USB cord and adaptive fast charging charger.
  • Check if the issue occurs when the phone is started in Safe Mode. If it doesn’t then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • As a last resort you can backup your phone data then do a factory reset.

If the above steps fails to fix the problem then you will have to bring the phone to a service center and have it checked.
