Samsung Galaxy S3’s mini version came out right after a few months of the S3 itself. The device was well received by the users, and became much popular because of being an affordable Android smartphone, specially among those who could not afford Samsung Galaxy S3 and wanted to enjoy some of the features of Galaxy S3 in a mini version.
Galaxy S3 mini boasted off a 4.0 inch Super AMOLED screen with 233 ppi, 1 GHz dual core processor, 1 GB Ram, 8/16 GB internal memory, while an external Sdcard slot supporting up to 32 GB. Out of the box, Galaxy S3 Mini runs on Android 4.1.1, while the device received an update to Android 4.1.2 after some time of its release.
While Android is an open source operating system and allows the developers to play with it in so many ways, and that being the operating system on Galaxy S3 Mini paved a way for the developers to develop custom roms, recoveries and mods for the device. Maclaw studios successfully managed to develop CyanogenMod 10.2 Custom Rom for Galaxy S3 Mini based on Android 4.3 recently. As off now the device is only upgrade-able to Android 4.1.2, there is no official update for Android 4.2.2 or 4.3, so this is a good choice for those who want to get their hands on Android 4.3 Jelly Bean’s features before it officially rolls out for Mini S3 (that is not going to happen anytime soon).
***Please keep in mind that as soon as you install custom recovery or root your device, you may void the warranty. As the methods involved in rooting/flashing/modifying your device are highly custom, and these have nothing to do with the manufacturer, that is Samsung in our case, so make sure that whatever you do, you are doing at your own risk. Follow the instructions explained below to the letter, in case you didn’t you may end up bricking your device and we may not be held responsible in that case.***
Before we begin, here are some pre requisites that you must have:
