Sterling Keys

Android 4.4 KitKat might be taking the lions share of the news recently, but there are still devices that are waiting for their time to shine with Android 4.3. While the Android 4.4 rollout schedule has been released, users who have older devices might just have to wait a little bit longer. Well, if you’ve got the Samsung Galaxy S3 an unofficial version of Android 4.3 has been leaked and is now available for you!

This is the first leak of the Galaxy S3 and while it seems to be relatively stable in tests, there could still be some bugs and whatnot that need to be ironed out. As well, since it’s an early build, there may be more features being added by Samsung by the time the official rollout actually begins. Some of the changes coming with this update will be an update of the UI and bringing it in line with the Samsung Galaxy S4 and Galaxy Note 3.

    Yeah Yeah,I am an absolute Nerd and at 70 certainly too old to be a flasher.Lots of chat about Kit-Kats and how wonderful the upgrades are. My Galaxy S3 i9300 is less than a year old and yet in phone time,its as old as me. I have decided that my steam driven Nokia that only phoned and sms'd was perfect for me. Now I'm totally lost and brassed off so "Beam Me Up Scotty"-time to go for this is a geeky world and I am no Spock. Goodbye cruel world.
