My galaxy Note 9 has started giving a green screen out of no where since this morning. Its very surprising how the screen turned green with horizontal lines while I was using the phone. So no drop, nothing bump the phone was in my hand and was showing the normal screen and suddenly the the screen turned green. I have tried restarting the phone and the after the screen still green.
Those observations only happened after performed Samsung update. The software information
Security patch level: 1 January 2021
