Screen Timeout not working in Android 12: How to Fix

In this guide, we will show you various methods to fix the screen timeout not working issue on your Android 12 device. The latest iteration of the OS build has struck a right chord between features and the stability front. Moreover, it has also been blessed with a major UI revamp in the form of the Material You UI and Wallpaper based theming engine. Then the likes of Gaming Dashboard and enhancement to the privacy front are also a welcome addition.

Unfortunately, it seems some bugs have also made their way over to the twelfth iteration of the OS. In this regard, the OnePlus and Pixel are the two OEMs that seem to be having quite a rough time. While it was along the expected lines for OnePlus (owing to its unwanted transition from OxygenOS to ColorOS), not many saw it coming for Pixel- which runs clean and stock OS experience without many customizations.

Anyways, as far as the screen timeout not working on Android 12 is concerned, there seem to be a few workarounds that have managed to fix this issue.
