If you’re still using the Samsung Galaxy S3 as a main device, or as a backup phone, you can now try something really unexpected on this smartphone. Yes, I’m talking about the latest Android 7.1 Nougat software that is now available for your smartphone as a custom ROM. The ROM is called AICP and promises a smooth and stable Android experience for the Samsung Galaxy S3. So, if you want to know more about the procedure to flash the ROM, do not hesitate and read this guide, which will help you run Galaxy S3 update to Android 7 Nougat.

If you are wondering how it is possible that this version of Android firmware can be easily executed on an obsolete device, remember that we are talking about a custom ROM and it is not the official software. AICP is developed by third-party developers and has nothing to do with Samsung or Google. The Android 7.1 Nougat ROM has been customized and optimized to allow a Galaxy S3 update in order to adapt perfectly with the performance of this smartphone.

Of course, the Nougat custom ROM comes with all the latest Android features, but with a modified system that has a different user interface. The AICP software that is installed on the Samsung Galaxy S3 should work much better, faster, not to mention that you can customize, optimize through third-party applications.

If you want to upgrade Galaxy S3 to Android 7.1, you should first make a hard reset of the device. Without deleting the Galaxy S3 system data you will not be able to use AICP firmware. So, as a precaution, first back up and sync your data with your Google Account, or use other similar services from Google Play or any other source. You should also make a Nandroid backup of all the files, in this way you can also save the Android system that is currently installed on your laptop, so that if the new Nougat Android platform is not to your liking, you will be able to go back without problems.

You can install Android 7 Nougat on Galaxy S3 only on an unlocked device with custom recovery installed. So, in our case you must first get root permissions on the Samsung Galaxy S3 and install CWM or TWRP Recovery. The ROM file is provided in the form of a .zip package which must be flashased only through a custom recovery.
Also, other pre-requisites must be considered before installing Android 7 Nougat on Galaxy S3:
