No, I haven't either. When i had 4.5.4I and 5.1.5G came out - I didn't get it. When had 5.1.5G and 5.1.6 came out- didn't get it also. Im not surprised,  meizu has fallen in my eyes significantly with their software. Maybe a good thing that software updates are so infrequent, because the next update brings more bugs than it fixed.

You're welcome. Forgot to mention. Didn't get an offer without root and with root.
