Finally, the Android 12 Beta 5 goes live for the eligible Pixel devices after the release of beta 4. Meanwhile, Google has also released the Android 12 Beta 5 GSI (Generic System Image) packages for non-Pixel Android devices that support Project Treble.
If you’re one of the Android users who is eager to get an early taste of Android 12 then you can follow this guide. Google has initially released the Android 12 Developer Preview 1 for its eligible Pixel devices in February 2021, followed by DP2, then DP3 respectively.
As Google has announced Android 12 Beta 5 for eligible Pixel models, we’re pleased to tell you that the GSI packages of the latest Android OS version are also available to download officially. Now, if you don’t know about GSI, take a brief idea below.
What is GSI in Android?

A GSI (Generic System Image) package is obviously a system image with adjusted configurations for Android devices that’s compatible with Project Treble support. That means Google has made it possible for all the non-Pixel Android smartphone users to flash the GSI package according to the device architecture and enjoy the latest Android OS version.
So, even if your device doesn’t support the latest Android OS officially, you’re still eligible for it. To be very specific, you’ll require an unlocked device bootloader irrespective of which Android device model you’re using.
Whereas it’s also worth mentioning that flashing the Android GSI package on your handset will perform a factory reset of your device completely.
So, you may lose your important data if you don’t back up your device before flashing it. Now, without further ado, let’s jump into it.
As mentioned on the official Android Developers website, Android 12 GSI binaries have the following GSI-specific known issues that you should keep in mind:
- Phone Audio: While using the stock phone dialer app, you may not be able to hear any audio on the device. It’s because of a change in the telephony service installation location in Android 10.
- Power Cycle: Restarting the GSI binary might fail on some devices. So, you may need to reboot the device into the recovery mode > erase user data and perform a factory reset. Once done, make sure to reboot the device.
- System partition size: GSI + GMS file size (images named gsi_gms_arm64-*) might be bigger than the default dynamic system partition size on your device. So, you may need to delete some of the non-essential dynamic partitions such as the product partition, and then re-flash the GSI again to fix this problem.
