Curious, it stated 2 major os updates as far as I can remember but it's still a capable mobile (not powerful, decent) i think origin os 6 should come to Vivo v29 as a final os update.

Vivo didn't really mention which mobile will receive the origis os 6 update apart from flagships so it'll be good to see the update on few old devices like Vivo v29 (it's not that old though)
