SAMSUNG GALAXY NX

To borrow a phrase, the Samsung Galaxy NX was 'business in front, party in the back. To the untrained eye, it looked like any other mid-range camera.

That there is a camera. Why's it special it looks far too normal for this page. 

You could mount lenses, prod a button to take a snap, and revel in the large (for the time) 20MP sensor. But spin the thing around and you were bathed in the glow of a 4.8in touchscreen. And that existed because this was the world's first mirrorless interchangeable-lens camera to run Android. You know, the phone OS.
