It is time now Meizu, Flyme, anyone relatively official, as KKPanda for example. We need feedback, we need a fix, a real fix and not some extremely long procedure that finally leads to nothing (thank you anyway User5210103352 for the time you must have dedicate to your post and the attempt to solve the problem).

I really think you should at least tell us you are working on it, officially, not through other customers that tell us you tell them that you are working to solve this.
