M01 m11 when launched their oneui was 2.0 So when a50ds was launched isamsung policy was for a series and m series was 2 years of os updates so ssxmaccording to that u will not get oneui 4.0 ythats all if u want query asjk samsung Those buffons in samsung service centre will tell u
Because Samsung promises two major update for A50 and A50s and others midrange device, your device already received two android operating system update, that's why u no more android update 😑
Galaxy A50s is not eligible for the One UI 4, A12 update coz it already got 2 major Android OS updates It launched in February 2019 with Android 9 Pie & got A10 & A11 Now you'll only get security updates... Kindly accept this as solution if u find this information useful🙂
