Fix iPhone 12 Pro Display Flickering Grey / Green Tint (No True Black)

We’ve already reported about the yellow screen problem of the iPhone 12 lineup. However, a similar issue has flared up that’s causing the iPhone 12 Pro display to flicker and show shades of grey (green) tint background instead of the true black color. This error can be spotted when the device is displaying a pure black background and the Brightness level isn’t sent to maximum.

How To Fix iPhone 12 Grey Screen Flickering

Apparently this is a software bug and should be solved by Apple in an upcoming update. You can apply the following troubleshooting tips as temporary workaround until we have the official fix:

1. Set Brightness To Maximum

The only known way to prevent this iPhone 12 screen flickering from happening is to set the device’s brightness level to the maximum!
You can either do this from the Control Center. Or from the Settings app.
If you do it in Settings you can also disable automatic brightness control and make sure that the high display intensity remains as default to prevent future grey screen flickering.
How To: Settings -> Display & Brightness -> Automatic (turn off)

Important: Setting your Brightness level to the maximum and displaying the automatic adjustment will considerably increase the battery drain of your device!

Tip: Some readers suggest that Brightness values over 90% should also work. You’ll have to test it out and see for yourself.

2. Reduce White Point

You can also try to enable the Reduce White Point accessibility feature, with the iPhone Brightness level set to maximum. This will force your devices screen to dim and avoid extra battery drain, while the Brightness setting stays at 100%.
Unfortunately, we couldn’t replicate this issue on our own devices, but we would love if you could try it out and share the outcome in the comments section available below.

• Open the Settings app.
• Scroll for Accessibility.
• Tap on Display & Text Size.
• Scroll for Reduce White Point and enable it.
  Tip: Use the slider to set the intensity of bright color reduction. The higher the values the more dimmed the display of your iPhone will become.
