11 Best Android 12 GSI ROMs You Can Install

The Best GSI ROMs For Android

Are you looking for a stable Android 12 GSI ROM to install on your treble-supported device? Then, this post is for you. In this guide, I will be sharing some of the best and most stable Android 12 GSI ROMs for all Android devices with project treble support.

Except your Android device has an official custom ROM support, finding a stable GSI ROM can be a daunting task as you will be required to download several GSIs, install and test their performance to see whether they can be used as a daily driver.

There are so many GSI ROM out there, each offering some unique set of features that makes it stand out. Some GSI focuses more on delivering a featuring-rich OS that will help you get more things done fast and easily, some have their strength in performance and we have a number of ROMs that give priority to security. In other to help you get away from the stress of having to download and test every new Android 12 GSI ROM you stumble upon, we have put together a list to help you pick the ROM that suits you.

What Is A GSI (Generic System Image)?

GSI or Generic System Image is a system image with adjusted configurations for Android devices that can be easily installed on a Project Treble-compatible device. It’s considered to be a ‘Pure Android’ implementation with unmodified AOSP (Android Open Source Project) code. Although project treble became official with Android 9 (Pie) almost all devices released with Android 8.0/8.1 Oreo comes with Project Treble support.

You can grab GSI ROMs for both x86 and ARM64 CPUs architecture and install on compatible Android phones. If you’ve been in the custom ROM community for some time now, you will know that there are several GSIs available for Treble-compatible devices, most of which are builds of popular custom ROMs Pixel Experience, Crdroid, AOSP, Havoc to mention a few. These GSIs bring a personalized Android experience for fans.

Advantages Of GSI ROMs

Faster software updates

Since project treble was introduced into the Android ecosystem in 2017, more Android fans have been able to easily upgrade their devices to a newer Android version with GSIs (Generic System Images). Project treble simply opened the door that was closed for many Android fans who have always wanted a custom ROM for their device. With GSIs, you can easily try out new Android OS versions on your device even when your manufacturer stops giving you updates.

Supports all devices

Regardless of what brand of device you have, you can install a GSI ROM if your device doesn’t have official custom ROM support. You can always try new Android OS versions like the just released Android 13 and others to come.

No bloatware

If you’re not using a Pixel device or devices running stock Android ROM, you’ll get lots of bloatware, many of which are just duplicate of apps that you don’t need. This is common among brands that offer custom skin like OneUI, MIUI, HiOS, and many more. GSIs, however, don’t give you that. Like custom ROMs, you get to decide what to install, leaving you with more free space and better performance.

LeOS is an AOSP-based ROM like many others, it replaces Google services with Micro G service so that your private data are not collected and sent to Google’s server. One thing I find really interesting about the ROM is the fact that you cannot install gapps (Google apps) and you’re not presented with device registration during setup.

Best Android 12 GSI ROMs

Although not a performance-centric ROM, this AOSP-based ROM delivers a decent performance that gets you through heavy multitasking and gaming. It has a simple and clean interface while offering several customization options to help you achieve the balance you want.

One thing I really like about the Project Blaze GSI ROM is the ability to choose between Android 12 and 11 QS panels if you’re not a fan of the new design. Personally, I find the new QS panel boring and having to do more taps to get things that usually require just a tap done.
