Problem: after plugging the phone in, using original adapter and usb cable, the phone begins to charge in fast mode, then after about 3 seconds, makes a tone as if the cable was unplugged, then plugged back in, and the charge goes from fast to regular.    Fast charging issue, i’ve tried multiple outlets, and my brother’s adapter and cable (same phone as me) same result. everything was working fine until the last update to the phone.

Solution: The first thing that you need to do in this particular case is to make sure that the charging port of the phone is free from any dirt or debris as the presence of any foreign matter will cause charging problems. Clean the charging port using a can of compressed air. Once the port is clean try using a different charging cord and adaptive fast charging wall charger to charge the phone.

S9 Not Turning On After Software Update

Problem: So the initial issue started after I got the notification that I had an update available. After the long 2 hour update which was just a security patch. I started getting these lines on my screen and then all of the sudden the phone shuts off and doesn’t power back on even to show that its charging. A week goes by and it is completely dead so I charge and all of the sudden it the screen comes back on but its stuck in a boot loop. I factory reset it, and cleared the cache partition and now it will not boot to recovery. I tried all the basic troubleshooting steps. IE safe mode, hard restarting it, even tried using odin but nothing will pass except the modem file. I don’t know if its because debugging isn’t enabled… I can’t find any article or forum related to this problem so any help would be much appreciated… thanks!

Since you have already performed most of the troubleshooting steps recommended for this issue which doesn’t’ fix the problem the best thing you can do right now is to bring the phone to a service center and have it checked.
