Hi my S9 plus has had a new screen and back in the past as it got run over! But for 4 months it’s worked fine. I installed the latest Samsung update 3 days ago and now the screen only stays on for 1 second, if I leave the phone for a few hours then tap the screen on button, it stays on for a little longer, 4/5 seconds.
I have tried the hard reset, plugged it into the laptop but with no success. The problem is that the screen isn’t on long enough to try anything else!(the phone seems to be working other than this)
When i try the hard reset, the Samsung logo and green emoji stay on for at least 5 seconds before resetting?? Yet my screen doesn’t stay on this long for anything else.
Could the motherboard be the issue?
I hope you can help?
