Back in February 2021, Google released the next version of the Android operating system, Android 12 along with different stages of its development, beta trial, and public release. At the same time, the US tech giant seeded the first Developer Preview of the Android 12 OS, which lets Pixel users understand and develop the ecosystem.

Following the schedule, the search engine giant delivered three Developer Preview builds with improved stability and system performance. However, Google has recently begun its annual developer conference, better known as Google I/O, where it is expected to unveil the Android 12 operating system in full-fledged.

According to the Android 12 schedule and speculations, Google will launch the Android 12 Public Beta at the Google I/O anytime, which will open the door for OEMs to let their consumers taste the latest Android operating system and help the company to develop its custom skin.


Ahead of the public beta, it looks like the official Android 12 Beta 1 Generic System Image (GSI) packages are already available for download! If you don’t know, GSI is a prebuilt system image that can be booted on devices that support Project Treble. (Credits – XDA Developers)

In simple words, using these Generic System Image packages you can get the Android 12 on a non-Pixel smartphone if your device compatible with Project Treble, and its bootloader has been unlocked. As with any other custom image installation, flashing a GSI will require you to factory reset your device.

Download Android 12 GSI


You should pick the appropriate version of the GSI binary based on your device’s architecture. To see which architecture your device has, run the following command: adb shell getprop ro.product.cpu.abi

Android 12 Beta GSI Installation

Make sure you have access to a PC or Mac with adb and fastboot installed, before attempting to install the Android 12 GSI.


Extract the .zip file, and copy and paste the resultant files (system.img and vbmeta.img) onto your ADB and fastboot folder on your computer for convenience.

Enable USB Debugging on your phone — Go to Settings > About Phone > Tap “Build Number” 7 times, (optionally) enter your pattern, PIN or password to enable Developer Options, and then navigate to Settings > Developer Options > Enable “USB Debugging”.

Connect your phone to your computer. Authorize your computer connection on your phone when the prompt comes up on your phone, if this is the first time you are connecting with this ADB computer.


On your computer, run: adb reboot bootloader

This will reboot your phone into Fastboot mode.

As mentioned earlier, the bootloader of the target device must be unlocked beforehand.


Next, we need to disable Android Verified Boot (AVB). To do that, run the following command: fastboot flash vbmeta vbmeta.img

Optional but recommended: Enter the following to wipe the system partition: fastboot erase system

Flash the Android 12 GSI: fastboot flash system system.img


Allow the image to flash, it could take a few minutes. Once that’s done, wipe the userdata partition: fastboot -w

Finally, reboot your device: fastboot reboot

Hopefully, your device should boot into Android 12 Beta.



  • Custom image flashing may brick your device.
  • If you don’t have basic flashing knowledge, then wait for the official release.
  • will not be responsible for any kind of loss, damages, or issues.

Android 12 Features: Google’s biggest and radical design update in years!



Update: Google officially launched Android 12 on October 4, 2021. Read more

On May 18, 2021, Google introduced the twelfth major generation of its mobile operating system, Android 12. Unlike every version, the company has made countless noticeable changes with this version such as new design, bubbly buttons, shifting colors, smoother animations, and much more.

At the same time, Sameer Samat, VP of product management, Android and Google Play revealed that it is “the biggest design change in Android’s history.”


No doubt, Android has always been about personalization and allowing you to select the device, service, and experience that’s right for you from the beginning. Google’s mobile phone operating system has grown to over 3 billion active devices around the world by providing an open ecosystem that gives you choice.

However, the public beta program of Android 12 has already begun for select smartphones from several companies except for Samsung, but we get to see the new feature directly from the company. Let’s start exploring them, in detail, one by one!


A more personal experience

As Google official revealed during the I/O, Android 12 comes with the biggest design change in Android’s history. Starting the colors to the shape, light and motion, Google entirely revamped the experience. As result, Android 12 is more expressive, dynamic, and personal than ever before.



As always, every single change of the newer version of Android will be implemented on Google’s Pixel phones. At the conference, Google said that Pixel device owners will be able to completely personalize their phones with a custom color palette and redesigned widgets.

With the Android 12, you only have to choose your wallpaper and the system will automatically decide which colors are dominant, which ones just look great, and which ones are complementary. Later on, it applies those colors across the entire OS including notification shade, lock screen, volume controls, widgets, and much more.

Google did this work in deep collaboration between its software, hardware, and Material Design teams. Not that all, the company is unifying its software and hardware ecosystems under a single design language called Material You. The company confirmed that Material You comes first to Google Pixel this fall.


Fluid motion and animations

Google has also simplified interactions and recrafted the entire underlying system to make user’s experience more fluid and efficient. With Android 12, your Android device will be faster and more responsive with better power efficiency so you can use your device for longer without a charge.

Redesigned system spaces


Notification shade, quick settings and power button, are some of the most important spaces on your phone, which have impressively revamped in order to help you get things done.

The Notification Shade is more intuitive and playful, with a crisp, at-a-glance view of your app notifications, whatever you’re currently listening to or watching.

Quick Settings that allows you to control the entire operating system by just a swipe and a tap, is totally refreshed to include Google Pay and Home Controls. While it still lets you customize as per your own preference.


Power Button will now allow users to access the Google Assistant by long-pressing on it, you can easily take the help of Assistant to make a phone call, ask questions, open apps, play songs, and many more.

Private and secure by design

Google’s latest Android 12 operating system brings new features, which presents more transparency around which apps are accessing your data, and more controls so you can make informed choices about how much private information your apps can access.


Furthermore, the new Privacy Dashboard offers a single view into your permissions settings and what data is being accessed, how often and by which apps. Besides, it also enables you to easily revoke app permissions right from the dashboard.

According to Google, it has added a new indicator at the top right corner of the status bar that indicates users when an app is accessing the phone’s camera or microphone. While if you want to remove app access to these sensors for the entire system, Android 12 comes with two new toggles in Quick Settings.

Aside from this, Android 12 also highlights more control over how much information you share with apps. The search engine giant claimed that apps can be limited to seeing just your approximate location instead of a precise one with the new approximate location permissions.


Additional Features

In addition to the above-mentioned features, Android 12 packs several useful features such as improved accessibility features for people with impaired vision, scrolling screenshots, conversation widgets that bring your favorite people to the home screen, and ways for all your devices to work better together.

What about stable Android 12?


Last but not least, Google confirmed that there are more features coming later this year with the stable release of Android 12. However, the US tech giant has not announced the launch date of the stable Android 12, but it could happen somewhere in September this year.
