A stands for the Chinese version of Flyme firmwares which is based on Android. Devices like m2 note, m3 note, m5 note ship with A firmwares in China.
Y stands for YunOS based Flyme. Devices like m2, m3, m3s ship with YunOS. YunOS does not support Google services although it is based on Android and it cannot be rooted too. Since Alibaba who developed YunOS has invested in Miezu, it's blue charm series devices are mostly released with Y firmwares. And because of some devices shipped on YunOS and others running Android, Meizu lost Google certification and it cannot include Google services and play store with the firmware as Google and AliBaba don't like each other.
