Motorola DynaTAC 8000x
The first commercial phone. It could only be used for calling and was not thin at all.

Phones got slimmer and more advanced. The new phones have screens and apps. -

In the future, I believe that the new phone will have a front-facing camera that is not visible and a screen that goes around the whole phone.
