Idk if beta is coming , but It should receive it , your phone has 4 major updates , but if they consider One UI 8.5 as a major update you won't receive even the stable One UI 9 , but I think they won't consider One UI 8.5 as a major update , because A06 has 2 major updates , but it is gonna receive it , even if it has only 2 major updates
Btw , if my comment is helpful , please click โฎ then accept solution ๐
