You can download and install Galaxy Note 3 launcher and magazine home if you have a Samsung Galaxy S3 with Android 4.3 Jelly Bean. The Galaxy Note 3 launcher is an improvement over Galaxy S4’s launcher as it brings new options and a changed navigation bar on both the home screen and app drawer. There is also better optimization and RAM consumption is very small.
The program has been successfully ported from a Note 3 Android 4.3 firmware and you can install it on your GS3. It also includes Magazine Home app and weather widget. The app has also been updated and now it doesn’t force close when you try to change the lock screen wallpaper.
