Every time I lock the phone and on it again in less a minute it appears green in shade and now it become green all the time don't understand what to do
I too face the same problem in Galaxy note 9. It started happening after August month security patch software update. I visited samsung service center, they checked and asked to wait for next update from Samsung. Hope Samsung solves immediately. It is very disappointing, I'm using Samsung mobiles for past 10 years, never faced this kind of issue.
