Android 12L freezing/delay bug (blank screen for 5-10 seconds) when switching between lock & home screen persists in beta 2

Along with the launch of Android 12, Google announced that they are working on a modified version of the OS that will be optimized for large-screen devices such as foldable phones and tablets.

Known as Android 12L, the tech giant released the Developer Preview in October and said that the stable version will be hitting markets in March of 2022.

That being said, a few hours ago, Google released Android 12L Beta 2 for Pixel devices. Soon, users noted that the Show Touches feature was removed from screen recording.

And now, it looks like Google forgot to fix another issue in the newly released beta. Many Android 12L Beta 2 users are reporting (1,2,3,4,5) that there is a significant delay when transitioning from the lock screen to the home screen.

Users say that it is really frustrating since they are unable to use the phone right after unlocking their phone. While some reports suggest that the OS is stuck on a blank screen, others say they see their wallpaper for 5-10 seconds.

Here is what some of those affected by the bug had to say.

But with Google yet to comment on the delay experienced when transitioning from the lock screen to the home screen on Android 12L Beta 2, it is still unclear if and when the bug will be fixed.

We hope Android developers soon find out the root cause of the issue and fix it as soon as possible. Nonetheless, we will be keeping an eye out on the matter and update this space as and when required, so make sure you stay tuned.
