S8+ Is Not Charging

Problem: I have a S8 plus running android oreo latest update.  My phone will not charge. I’ve run through the usual soft resets, factory default reset, and I’ve even had the charging board in my phone replaced – but it does not fix the charging functionality.  This is the phone that I’ve owned that I believe was bricked by Sprint and/or Google via an update. Any other ideas or recommendations to get this thing working? Thanks. sidenote: Yes I’m using a samsung branded power block and usb cable.

Solution: Since you have already performed a factory reset and and even had the charging port of the phone replaced which does not fix the problem then this is most likely caused by some other component that is failing to work properly. Some of the main suspects include the battery and the power IC. The best thing to do right now is to have the phone repaired at a service center.

S8+ Moisture Has Been Detected

Problem: Moisture has been detected. Unplug the charger and wait until the charger and usb port are dry. It was working fine when charging until I moved the charger to another outlet and received this error message. The phone has not been anywhere in water or moisture. I’ve been receiving this error messages about 5-6 times within the past week.

Solution: The first thing that you need to do in this case is to make sure that the charging port of the phone is free form the presence of moisture. Use a mini vacuum or hair dryer to dry out the port. If you see dirt or debris in the port then use a can of compressed air to clean the port. Once this is done check if the phone will charge. If the error message still pops up then you will have to proceed with a factory reset as this might be caused by a software glitch. Make sure to backup your phone data before doing the reset.

S8+ Will Only Show Black Screen

Problem: My phone only show a black screen will not power on attempted a soft reset by holding power button and power down key. Then tried power up and power on key.  After letting it sit the clock and date screen came on but when I touched the home key the screen went back to black. Message alerts can still be heard.

Solution: The best thing you can do right now is to check if the problem is caused by a software glitch by starting the phone in recovery mode then doing a factory reset in this mode. Take note that the reset will erase your phone data.

If the screen still remains black then it’s likely that this is already a hardware related problem. The best thing you can do right now is to bring the phone to a service center and have it checked.
