The OnePlus 9 and OnePlus 9 Pro are two flagship smartphones released during the first half of 2021.
Being flagship phones, the OnePlus 9 and 9 Pro were the first OnePlus smartphones to receive the update to OxygenOS 12 (Android 12).
The initial release of OxygenOS 12 for the aforementioned devices was a bit bumpy. However, over the months, the company has corrected many of the reported bugs.
But there are still some issues that OnePlus 9 series users are facing after the update that require a fix. For instance, multiple reports point out that there are problems with the screens (1, 2, 3, 4, 5, 6).
More specifically, some OnePlus 9 and 9 Pro on OxygenOS 12 (Android 12) reportedly have screen flickering or horizontal display lines. However, there are some potential workarounds that could help.

Some users of OnePlus 9 and 9 Pro devices report an annoying screen flickering issue that appears randomly on Android 12 (OxygenOS 12).
Screen Flickering after updating to oxygen 12
Please help , my OnePlus 9 pro screen is Flickering sometimes when I unlock or in Home page after updating my Phone to newly updated stable version of Oxygen OS 12 , can anyone help me to fix this? I can’t take screenshot coz it appears sometimes and screen looks like broken on those times.
Hello, so since the last update my phone screen has been flickering… Sadly I don’t have a screen shot of it, because it usually flickers and parallel horizontal white bars run across my screen when the phone is just about to go to sleep. Its kind of a random occurrence. I am currently running Oxygen OS 12.
The problem appears in the form of thin horizontal lines emerging randomly on the screen and for no apparent reason.
The effect caused by screen flickering can be clearly seen in the following video:

Hi everyone. I was facing screen flickering with horizontal lines issue suddenly. I want to know why it was happened suddenly.

A couple of potential workarounds
There is still no official acknowledgment of the issue by OnePlus. However, there are a couple of potential workarounds that reportedly resolve the screen flickering pending an official fix.
First, you can try to apply the following procedure:
I simply picked a color in settings>personalizations>always on display>display settings and it has always worked.
Another potential workaround is to set the screen resolution to Full HD+ instead of QHD+:
We will update this story with any new related events that arise.
