Meizu’s Android 4.4.4 KitKat based Flyme OS looks and acts a lot like iOS with a great level of refinement and attention to perfection, but holds all the Android features. A ‘Flyme OS’ port is now available for Nexus 5 that you can install on your phone and enjoy a totally different user experience on your Nexus 5.
The Flyme OS for Nexus 5 is based on CyanogenMod 11 ROM (Android 4.4.4 KitKat), but the user experience will be entirely different. It does not have a traditional Android UI, so you will definitely enjoy something different on your Nexus 5.
As always, back up your Nexus 5 completely (Nandroid backup from recovery). Also, back up all phone data such as personal files, images, videos, messages, emails, contacts, apps, SMS, call logs, bookmarks, etc.
