Samsung’s new slot can be used for both UFS and microSD cards
Recently, Samsung announced new UFS cards that is supposed to be the successors of MicroSDs. However, there is one problem. You cannot use this card with any of the existing device.
As a result, manufactures need to include a new slot to support UFS Cards but that would prevent users from being able to use MicroSDs. However, Samsung has a solution. They designed a new slot that can be used for both of the cards.
I guess it is not a coincidence that Samsung announced a new slot ( that can also be used on mobile devices ) one month before the introduction of Note 7.
