Google Pixel 4 and Pixel 4 XL owners are some of the few users that can check out the Android 11 Developer Preview update. The Developer Preview builds are early builds and are bound to have a few bugs and glitches. Google releases these preview builds to help developers test their apps with the upcoming Android version. Thus, these updates are aptly named ‘Developer Preview’.
Of course, installing the developer preview update on your ‘daily driver’ is not recommended. There are a bunch of problems or bugs that pop-up which might lead to poor user experience. Nevertheless, after downgrading from Android 11, some Pixel 4 and Pixel 4 XL users are not able to use the Face Unlock feature.
This problem is already well-documented and Google knows about the existence of the face unlock issue. It’s mentioned on the Android Developer website in the Android 11 Release Notes. Unfortunately, the Google Pixel 4 face unlock issue cannot be fixed by a quick patch at present. Moreover, it will likely be fixed only when the official Android 11 OTA update arrives. In case you too are stuck with the same problem on your Pixel 4 or Pixel 4 XL, don’t fret. There’s an unofficial workaround thanks to the developer community. Follow the steps below to fix the Google Pixel 4 face unlock issue.
How to fix Google Pixel 4 Face Unlock issue
The process to fix the issue might seem a tad complicated. However, if you follow the step by step instructions below, you should be able to fix the problem.
- First off, you need to downgrade from Android 11 to the March or April build of Android 10 for your Pixel 4 model.
- After downgrading, you will have to root your Pixel 4 or Pixel XL. Make sure to follow the instructions in the guide correctly to avoid bricking your smartphone.
- After you’ve rooted your Pixel 4/4 XL, download the Magisk Module from here.
- Install the Magisk Module on your Pixel 4 or Pixel 4 XL.
The module seems to fix the problem by addressing the kernel conflicts after downgrading from Android 11. You should now be able to use the Face Unlock feature on your Pixel 4 or Pixel 4 XL. It’s worth noting that this method is only a workaround for the problem and isn’t an official fix. In case you do not wish to delve into rooting and installing Magisk Modules, you will have to wait until Google releases a fix. And as we mentioned earlier, the problem might only be addressed once the stable Android 11 build is released.
