samsung policy says that u will get 2 major android updates and 3yrs security patch, u will definitely get security patchs but not android update, even s8+ is not in device list which will gets android 10,
@VENKATESH, They said the same blasphemy on 2019 for Galaxy S7 Android Pie. And yet, I didn't get it. As per Samsung's update policy, You'll get only two major OS upgrades. On the other hand, They'll continue with security patch updates.
