The Android 12 Beta 3 update released a couple of weeks ago was the most polished and feature-rich update in the Android 12 ecosystem. However, it was also the most buggy with issues like random system UI crashes, removal Aggressive background apps and boot loop when restarting the phone. The latter causes the phone to get stuck in the boot cycle and is very frustrating for users. That has now been fixed with the Android 12 Beta 3.1 update along with other minor bugs reported by the developers.
It also has Google Play services version 21.24.13 and API 31 for developers and not many changes to the user interface are expected with this version. The Beta 3.1 update has build number SPB3.210618.016 and works with x86 (64-bit) and has ARM emulator support (v8-A).
This update is not yet recommended for users who will be using their device as a daily controller as there will be minor bugs as the operating system is still in beta. With that said, the next Beta 4 update that is expected in late August will focus on stability, making it a better bet for enthusiasts.
Developers can manually download this latest beta update via the downloadable factory and OTA images right away. Eligible devices, including Pixel phones, will see a message for this version update shortly, so downloading it makes perfect sense given the buggy nature of the old one.
