Current Meizu smartphones come with Android 4.4 operating system, but the company is working hard on a new OS for Meizu MX4 and MX4 Pro called Flyme OS. The new OS from Meizu will be based on Android 5.0 Lollipop and should arrive next month, in March.

It should bring all Lollipop features with some own improvements and different user interface. Not much is known about the OS, so we'll have to wait for March.
