Yes, you read it right! Now you can install the Android 12 OS on the Samsung Galaxy S3, which is now nearly a decade old, and enjoy all the features of the modern Android system in 2022! If you have been following us in the past few years, then you will know that there are many companies currently sending the latest Android 12 update with their own custom interfaces such as Samsung with One UI 4 or Oppo with ColorOS 12 as well as Xiaomi with MIUI 13.
All of these companies have one thing in common, these updates only reach phones that are “officially supported” with them, or those devices that are still not three years old at the least. But there is an important question for thousands of other users, which is, what will happen to the phone if it has been launched for more than three years and is not officially supported for these updates? Will it really be abandoned? Well, don’t worry, because with Android everything is possible!
You can now update your 10 year old phone!
When we talk about operating system support for Android devices of all kinds, there are some phones that continue to amaze us constantly. While this phone may not be supported as strongly as the Samsung star of the previous years Galaxy Note 3 and the huge amount of ROMs support and custom tweaks only dedicated to it, the Samsung Galaxy S3 still maintains its status as one of the best Samsung phones ever! The Korean giant may have abandoned support for this legendary phone a long time ago, but the developer community has never abandoned it.
Android 12 is now available for the Samsung S3!
Yes, the 2012 Samsung flagship “10 years ago” is now supported for Android 12 via the LineageOS 19.0 ROM (unofficially, this version is not from the official ROM developer team). Now, as a user of it, you can enjoy all the new features of the Android 12. Even, the system is surprisingly very stable, suitable for everyday use if your Galaxy S III is your main phone!
Samsung Galaxy S3 3G version with Exynos 4412 the GT-I9300 variant today is able to install Android 12, thanks to the developer html6405 of XDA.
What is working?
But if you are wondering what things work if you want to have this wonderful experience, they are as follows:
- Culler radio
- Camera with all its modes
- Play all the usual video extensions
However, here we are talking about an initial version of the ROM, so you will find that this version of it lacks many of the usual features of LineageOS ROMs. But this is very normal, because as we mentioned this version is still in its initial alpha stages, so we expect the developer to add all these features in the upcoming versions.
Yes if you ask, when we talk about unofficial tools, you will often find that there are bugs too! As for the errors and problems themselves, they are as follows:
- The SIM PIN feature is not working, so you will need to remove it on a different device first.
- Formatting the external SD and use it as internal memory unfortunately does not work either.
- The NFC feature of the Galaxy S3 does not work in this version.
These are the known bugs and problems with the ROM so far, and we hope that the developer will fix them in the next releases. So, if you happened to be a Samsung Galaxy S3 user and it is now a thing of the past and stuck somewhere in your house, now is the time to revive it and install the latest Android OS to date on it.

Custom ROMs installing guide
Of course, today’s explanation isn’t for beginners, and you’ll need some knowledge of what we’re talking about today. But despite that, everything has a beginning, and this page may be your beginning to enter this wonderful world full of new things. So, if you decided that you wanted to give it a try, so go ahead and see what we are saying next, carefully!
If you are new to this matter, and you are implementing it for the first time, besides that you have reached this page by searching for something and then you found us by accident, then perhaps you should know that there are some necessary requirements first before you go to install the modified Android ROM on your phone.
- Save a backup copy of the phone files.
- Unlock your device’s bootloader.
- Install TWRP custom recovery – Use this version: S3 TWRP
- Do an NANDroid Backup.
- You will also need to download the Google Apps bundle from here: BitGapps, arm, 12
install a custom ROM via TWRP
- Download the ROM file from the links attached above, then transfer the files to the internal or external memory.
- Reboot into TWRP recovery mode.
- From the recovery main menu, go to Wipe> Advanced wipe, then choose the System, Data, Cash, Dalvic sections, and then drag the Swipe button below to execute. This process will remove the current system from your device.
- Once again from the main recovery menu, go to the Install button, then browse storage files to the ROM file on the external memory.
- Once the ROM has finished flashing, press the Reboot System button that will appear below.
You probably know this since you are reading these steps, but the first booting after flashing any of the above mentioned Android 12 ROM usually takes a long time, so do not worry, this is normal. Given that these ROM are not official but from some independent XDA developers, there is a possibility that the phone will not succeed in the first booting, and therefore you must be ready for all possibilities, So we mentioned making a backup NANDroid within the necessary requirements.
