I do have both positive and negative experience with flyme. i Wish someone read this. I have Meizu Mx 5. This phone has an amazing camera but a poor screen. so all i must do is transfer my photos to my personal computer and see the beauty of the photos. Flyme os drains my battery heavily and takes a large system memory which reduces the space available for me to use. i have never experienced a lag in my mobile as iam not a gaming person. Phone doesnt get heat compared to other mobile. As for as meizu design is concerned, every product looks same and it needs serious r/d development.. The flyme os doesnt support volte and i have to use an app for calling which drains my battery a lot. compared to similar brands meizu needs to update its features like adding i/r remote controller,front cam with flash and good screen which is available in those price range.. Flyme os needs a serious consideration for draining battery and usage of system memory...
