I got green tint issues on low brightness after update ios 16.

Gragasov,

If you think that is the case, it might be related to a hardware concern with the screen since it happens during boot. This link can get you started with service options: iPhone Repair & Service - Apple Support

Enjoy your day.

Hello Gragasov,

The behavior you're describing can be expected for Super Retina XDR display. You can find this information and more under the "OLED technology" section of About the Super Retina display and Super Retina XDR display on your iPhone.

"If you look at an OLED display off-angle, you might notice slight shifts in color and hue. At reduced display brightness levels against black backgrounds, you might notice a slight blur or color change while scrolling. These are characteristics of OLED and are normal behavior."

Take care.

Mine is doing the same thing, I talked to Apple and they did a diagnostic on my phone and said at definitely wasn’t a hardware issue, I restored my iPhone 11 Pro yesterday and the issue is still there, and the black parts of my phone, when my screen is supposed to be showing black, is showing weird big green pixels
