Sudden display issue galaxy note 10

Try restarting the phone. From the samsung logo itself, if this issue is happening, its probably a hardware issue that needs to be corrected by a samsung repair center, if not and the issue happens after some time of the phone starting, meaning the greenish appearance comes after a while after starting the phone, maybe a factory reset might help since its a software issue.

From personal experience if the screen is getting darker and darker , u might have a screen issue and needs to replace the screen. Hope this helps a little bit

Try the below:

1. Turn ON always on display, choose "home button and clock" and "then tap to show".
2. Now turn off the phone with the physical button.
3. Then touch the screen, the clock appears. Under it, there is the virtual key.
4. Turn on the phone with the virtual key.

Check if your screen issue persists after this?

Also have you tried starting the phone in Safe Mode?
