This GenNxt Custom ROM is based on Official Android 4.3 released by Samsung, but there are many changes in it, and its easy to find changes. This ROM comes with many amazing features and the best part, it is already rooted so you can enjoy the best out of all those features and also install all those apps, which requires root access.  Along with that, many features from Samsung Galaxy S5 Kit-Kat firmware has been ported in it as well. This is most probably the only Custom ROM available for this device yet, so get your hands on it while it is fresh and this might be based on Android 4.3 but many of the Kit-Kat features are there as well to give you some experience too, and developer has promised to update this ROM as soon as possible.

But why would anyone go for a Custom ROM instead of staying on the Stock On, allow me to explain. “Stock and Official ROMs are good, but they are created with keeping in mind the demands of all, some want performance and some want speed, some want looks, some want features. Putting them altogether in one ROM can cause a Lag, Performance issues and bugs. But Custom ROM is basically designed for either Looks or Performance and Custom ROM gives speed and great performance with Tweaks and System Tools.”
