S22 Ultra Doesn't Display Blacks Properly

[Members_4OTmYit]

I noticed very recently that my S22 Ultra doesn't display blacks properly. When I'm on my always-on-display, sometimes the screen goes from "normal" white text and all-black background, to white text and "greenish-hue" background.

When I went and unlocked the phone, the issue's gone.

When watching Netflix, when there's a transition(fade to black) between scenes, it's supposed to be black, but it flickers to reddish then greenish again.

So I tried using the *#0*# diagnostic tool, and tested it there. The colors are normal, but when testing black, the screen just shows a greenish hue instead of displaying black.

There's no problem displaying blacks on my wallpaper though, probably because there's some color involved, so I don't know what the problem is, really.

Is this just a software issue that'll get patched in the coming update, or is this a hardware problem?

I'm using this phone as my daily driver, it's really a hassle if this needs to be sent in to be repaired.

Update your S22 Ultra to the August security patch. Then, wipe cache partition. The update will fix this issue.
