S9+ Randomly Turning Off

Problem: Recently received a new Samsung Galaxy S9 plus. The phone is turning off and is difficult to turn back on. The issue has been there since day 1, about 10 days. I have to plug the charger in and wait a few minutes when the charging symbol appears. I have to hold down the power button to turn it on, which may take a couple of times. It seems to be happening when there is no activity on the phone, such as checking emails or sending text messages ,Etc, like overnight. It seemed ok during the week when I was using it for work. I don’t use a SD micro card in the phone. I even tried to keep the screen alive all the time but it still happen. Any help, thanks.

Solution: You need to check first if the problem is caused by one of the apps you installed. To do this just start the phone in Safe Mode then check if the issue occurs in this mode. When your phone works in this mode only the pre-installed apps are allowed to run. If the problem does not occur in this mode then it could be caused by one of the apps in your phone. Find out what app this is and uninstall it.

If the issue still occurs even in Safe Mode then you should backup your phone data then start the phone in recovery mode. From here do the steps listed below.

  • Wipe the cache partition of the phone.
  • Do a factory reset.

Once the reset is complete do not install any apps in your phone yet. Try to check first if the issue still occurs. If it does then this is most likely caused by a faulty hardware component in which case you will need to bring the phone to a service center and have it checked.

S9+ Freezes When Connected To Charger

Problem: When I plug in charger on my phone the volume goes erratic. It then freezes up. I have done soft reset, hard reset, even cleaned the charging plug inside, even changed charger. Still will not charge without powering down multiple times. I even wiped the cache partition. Still freezes when I plug in charger

Solution: Since you have already performed the recommended troubleshooting step for this problem then this looks like it is caused by a faulty hardware component already. My guess is that a component inside the phone gets shorted whenever the charger is connected which then results in the phone freezing. The best thing you can do right now is to bring the phone to a service center and have it checked.

S9+ Moisture Detected In Charging Port

Problem: My phone keep saying there is water or moisture in my charge port when I go to plug my charger in and there is no moisture anywhere. In fact it was charging last night and I accidentally unplugged the Box and suddenly when I plug the Box in it says there’s moisture in the port. It’s just very random and there is absolutely no liquid anywhere near my phone or charger.

Solution: Just to make sure that there really is no moisture in the charging port you should use a mini vacuum or a hair dryer to remove any traces of moisture in the port. Once this is done try to check if the issue still occurs. If it does then this might just be caused by a software glitch which can be fixed by performing the steps listed below.

  • Perform a soft reset by pressing and holding both power and volume down buttons for at least 10 seconds. Check if the issue still occurs when the phone starts.
  • Backup your phone data then do a factory reset.

After sometime it started coming on and off again and again showing installing updates but still it is not turning on it’s been one hour now please help

Solution: The best thing that you can do right now is to start the phone in recovery mode then wipe the cache partition of the device. Restart the phone then check if the issue still occurs. If it does then you will need to start the phone in recovery mode again then do a factory reset. Take note that this will erase your phone data.
