Grey/Faded black screen after lastest software update

[Rees91]

 I did a system update on my S23 Ultra Friday, but from yesterday I noticed that if I have to open anything with a black background it's showing as this faded washed out black or dark green colour. Even my whatsapp is now a faded black, almost grey or green screen. But everything else is normal. Anyone else has this problem?

Is your lcd the origional AMOLED?

Use a Test Image:

Create a Test Image:

Create a simple image with a solid black background and a white square or rectangle in the center. 

Observe in a Dark Room:

Display the image on your screen in a dark room and observe the black areas. 

AMOLED vs. LCD:

AMOLED: If your screen is AMOLED, the black areas should appear as true black (no light emitted). 

LCD: If your screen is LCD, the black areas will likely appear as dark gray, as LCD screens use a backlight that is always on. 

If it's AMOLED then it could software glitch related, you might need to contact support
