Flyme OS is a skinned version of Android made by Chinese developers of the Meizu team for the MX line of smartphones. It has become pretty sought after with it's elegant design cues. The Flyme OS is based on Android 4.4 Kit Kat. You don't actually have to purchase an MX device to enjoy Flyme. The Flyme Rom has been officially ported over to the Nexus 5! The Rom is said to be completely working with only a few bugs that would not keep you from using it as a daily driver. In other words all the important stuff (camera, bluetooth, wifi, gps, 4g, ect) is working perfectly fine. If you are interested in trying out Flyme head to the source link below.
