Nested Contact Groups on Samsung Devices

The contacts app on Samsung phones offer the ability to view contacts by groups. This can be done by clicking the group icon, next to the search box. The device will recognize all contacts for an Exchange account, even in nested sub folders.

It is not possible to view contacts by their nested folder folder name. To separate contacts in this manner, each contact will need to have a category assigned to it using the name of the nested folder. Once this is done, the contacts will be grouped by category under Integrated Groups.
