Exciting things happen when developers are at their creative best. These innovations pave the way to newer and better Android developments that can enrich and optimize our user experience. At the XDA Developers forum, developers are always at their creative best, especially for the Galaxy S3. Sometimes, a gorgeous and functional ROM is developed for a certain phone on a certain carrier and people will have to wait for months before it is ported to their own device's carrier. This ROM, however, makes sure that you don't have to wait to enjoy this ROM on your device. Fresh from XDA Developers member itsmikeramsay is the Illusion ROM and it is available for the Verizon Samsung Galaxy S3 SCH-I535, the T-Mobile Samsung Galaxy S3 SGH-T999, and the AT&T Samsung Galaxy S3 SGH-I747.
The Illusion ROM is based on the latest Android 4.2.1 Jelly Bean and it gives you access to those sweet Jelly Bean features and CyanogenMod 10.1 goodies. Performance-wise, the Illusion ROM runs smoothly and is stable enough for daily use. However, there are a few issues that need to be worked out, such as the camera, headphone jack not working during calls, lockscreen shortcut force closes, tethering, and MTP support.
This guide shows you how to flash Illusion ROM for the Galaxy S3.
