I am a Mi 9 owner, and the phone is excluded from Global Stable updates. Why do you think I am here ?
I would even use the Chinese Stable, but I have no idea if that is updated properly, and I presume it is not.
Global Beta was my preferred ROM, now that's done, so ... either I use the ancient Global Stable, or a Xiaomi.eu variant.
But I would not complain, if Xiaomi would provide decent updates, at least once per month, security patches and what not, the odd new option, I'd be more than happy, but they do not, so it's their fault, not Xiaomi.eu fault for not having the latest China Stable converted (no, I have no clue what the latest China Stable version is).
