Guys dont ask for minor updates like security patches..dont argue by comparing your models with j7 prime and c9 pro that J7 prime got two updates after oreo becoz it had ram mamagement issue they resolved it by these updates...
While other models are perfectly bug free hence they didnt get updates..
One of the reasons for delay in oreo update for j7 and j7 max is fixing the bug like not to release buggy oreo as the j7 prime bug when oreo released...
