Hi all!
As far as I know meizu has different versions of their phones for china market and global. For example my Meilan M1 Note is m463M, but there's another version m463U.
On TENAA site I found info about new M5 Note versions M621Q, M621M and M621C but there's one difference : first has 4000 mAh battery, the others have 3920 mAh. So, is there any other differences? Which of the versions is the global one??
Which is the best?
