Note 9 issue

[JIMTAU]

I have screen discolouration, sometimes goes black, and water detect issue with my Samsung Galaxy Note 9 since last 3 days. I am not sure if this is because of the last security patch update. I didn't have any physical accident with my device only after this happened, when I was frustrated and dropped it on the floor thoughis not of concern. When the brightness is varied and kept in middle, the screen becomes dull greenish/yellowish with horizontal lines. This is so annoying. the screen goes totally dull, with greenish/blackish horizontal lines and I can't even read what's on the screen.

Hi  JIMTAU 

Please try the following steps : 

1. Please go to Settings>>Apps>> Tap on the 3 dots on the top right corner>>Show System Apps>> Software Update>> Storage>> Clear Cache.

2. Then please perform a soft reset of your device.

Press and hold the power and volume down buttons for about 10 seconds.

*The device may take a screenshot, however keep holding the buttons for a few more seconds.

If the issue still persists, you may take the device to the service center for an assessment.

I have done so, the problem was not fixed.
it will take a while for me to visit service center due to COVID-19 regulations in my organization.

Try to restart your phone but before you do that make sure to backup your data using smartswitch on your computer this should solve your problem
