It will get the stable version straight up . But for now , Samsung is rolling out One UI 3.0 for Core versions in Mseries . After that , A series will get Full Onu UI3.0 with better optimisation and less bugs. What i think Samsung is doing is that it wants better performance and user experience for A series , so its first givin it to M series , and as we all see , all phones with One UI3.0 have some battery , calculator and camera bugs . So pls wait a little more to get bugless updates
