OmniROM is filled with many features from Samsung devices and when I said for Samsung then it means, it contains features from all the Flagship devices including the most demanded one, Multi-Window, it is considered as one of the best ROMs available out there. No matter on which device you install it, OmniROM is sure to give it a whole new life and for you a whole new experience. Other features include Quick Settings flipping tiles, screen recording, GUI translucency. Aroma installer has been ported to give you an easy and reliable installing experience, which is actually far better than the stock installation, where you have no idea what is going on until everything is over. Screen Recording has also been ported in the ROM, which is really one of my favorite. The latest OmniROM is based on Android 4.4.4 Kit-Kat and we are here to show you how to download and install it.
