Meizu MX4 and MX4 Pro should be updated to Android 5.0 Lollipop starting next month
According to Chinese website MyDrives, Meizu will launch an open beta of the new Flyme OS at the end of March, with a final build likely arriving not long after that.
Both the Meizu MX4 and MX4 Pro are available since last year, and run a Flyme OS variant based on Android 4.4 KitKat.
The MX4 is a 5.4-inch (1152 x 1920 pixels) handset that's powered by an octa-core MediaTek processor, while the MX4 Pro is slightly larger and a bit more advanced, featuring a 5.5-inch display with 1536 x 2560 pixels and an octa-core Exynos 5430 processor. We liked both the MX4 and MX4 Pro when we reviewed them (see here and here), and the latter actually impressed us.
