what do you mean?

Meizu devices are not Google certified because of an ongoing partnership with Alibaba. Due to that a rule of Google's certification requirement wasn't being met. As a result, Meizu devices are uncertified. But as we've heard from leaks that partnership is most likely over so we may see certification soon.

Does this mean old Meizu devices such as Meizu m3 note would not get google certify? Or would it?

they are not certified
