There is a cruel irony with software updates. You install them to protect your device from security threats and keep it running smoothly, but sometimes the very update meant to help ends up causing problems. This week, owners of Google’s Pixel 7, 8, and 9 phones are facing a new issue. The March 2025 security update, intended to fix security issues, has instead caused screen issues.
The Flicker and The Fade
It’s like trying to read a book while someone randomly dims or flickers the lights. That’s been the experience of thousands of Pixel users. A bug inexplicably reduces screen brightness. You might be writing an email or watching a YouTube video when the display suddenly dims, even with auto-brightness off.
Worse, there’s a flicker: some users reported a strobe effect on the display when watching video or scrolling through high-contrast apps like Twitter (X) or Reddit in dark mode. For those with photosensitive conditions, this issue has rendered the device useless. The problem appears to be a clash between display drivers and March’s kernel updates.
Why Does This Happen?
To understand this, picture a smartphone as a complex orchestra. The hardware (screen) is the instrument; the software is the sheet music. The March update changed some notes—making things more secure. Now the conductor (the operating system) seems to misread them, instructing the screen to play quietly (dim) or, at odd times, unleash a cacophony (flicker).
Regressions like this plague modern software engineering. Despite extensive testing, the sheer number of variables—installed apps, unique settings, different hardware batches—means some bugs only surface when the software goes live on millions of devices.
Google’s Response and What You Should Do
The good news, if you can call it that, is you are not hallucinating. Google has acknowledged the reports. Engineers are examining the code to identify lines causing the display driver (the software that controls your screen) to panic or crash. A fix is in development, so a point release (a small update) will likely arrive in the next few days or weeks.
Affected users remain in limbo. Some have resorted to turning off Adaptive Brightness or setting the refresh rate to a fixed 60Hz, but these are mere Band-Aids. If you use a Pixel 7, 8, or 9 and haven’t installed the March update, it’s best to wait. Let early adopters weather the storm while Google fixes things.
