I’ve tried reaching out to my contacts at Meizu to no avail regarding this issue.
In fact, my old MX4 has the SAME exact issue.

I am hoping that with this video I can finally get an answer, and maybe then Meizu will fix the issue not just with the upcoming devices, but also the previous and current ones.
