Galaxy S2 Plus’s life ended on Android 4.2.2 Jelly Bean. We haven’t seen any update for this device in a long while nor we are expecting Samsung to have a look back. Due to hardware limitations, Galaxy S2 Plus has to stay on Android 4.2.2 Jelly Bean now. The device got higher versions of Android but in the form of custom ROMs. We already have posted the guides to update your Galaxy S2 Plus to Android 4.4 KitKat, Android 5.0 Lollipop. Now that Google has released Android 6.0 Marshmallow, the next firmware that Galaxy S2 Plus users are expecting is the custom Android Marshmallow ROM. The good news is, a pure AOSP custom ROM has already made its way towards the Galaxy S2 Plus I9105 and I9105P.
