How do you animate 3D - Models in Power Point?

I have a subscription for Microsoft Office 365 products and presently I have the Version 1806 (Build 10228.20134 Click-to-run).

With this launched, I can see under the Insert | Illustrations group 3D Models. After you insert the model you can highlight it and click the Animations Menu item which brings up the  3-D animation related  'ribbon' displaying the various effects possible.

You can create your own 3D-Model using the Paint 3D program on most Windows 10 computers; or use models created by others in the Gallery which is accessible from Paint 3D.

You can then animate the models and even add regular animation as well.

Here is an example of 3D animations on Your tube:

What is Samsung Dex?

It is more correct to call it Samsung Dex Station (hardware) that pairs with Samsung's Galaxy S8 phone to provide you a real desktop experience that you always wanted.

Hear what VMware calls this:
"Samsung DeX redefines what a smartphone can do to keep mobile workers productive with just their smartphones."

Your Samsung Desktop would consist of a computer monitor, keyboard, mouse, Samsung Galaxy S8 and the Dex Station.
Review the below image:

As you can see in the above image, Microsoft is there with all its Office 365 products.  Microsoft's dream of entering the mobile world may still be realized although Windows Phone is near extinction.
Microsoft has played a smart hand in going with Samsung on this.

Looks like Google Drive is still accessible and there are still few more programs(Hancom Office, Citrix Receiver and VMware Horizon Client).

Hancom Office consists of Hanword (a.k.a. Hangul, hwp), Hancell (Spreadsheet), and Hanshow (Presentation program).

Citrix Receiver is a suite of products that allow client devices to connect to various desktop virtualization services offered by Citrix.

VMware Horizon:
VMware Horizon delivers true Windows desktop and applications computing experience on Samsung Galaxy S8 through the VMware digital workspace and Samsung Desktop Experience (DeX)
