after waiting a long time i came to know that flyme 6 global will be rolling out in April this year, without waiting for that i have installed flyme6  6.0.1.1A which is Chinese firmware on my device m3 note. here is my experience of it.

1.you'll get some Chinese app which can be uninstalled.
2.i found not so big difference between flyme 5 and 6.
3. you may get problems of google play store installation.
4 user interface not much change.
5. flyme 5 was even smoother than this.
6. i found battery life better in it.
7. in flyme 5 multi window option was there for some apps, but in flyme6 you don't get that.
8. animation are different from flyme5.
9. camera customization given.
10. heating issue not present.

Over all guys if you're expecting extra ordinary changes in flyme6, i'll say you'll will be disappointed of this flyme6. not much changes you'll find. i am sharing some screenshots.
