**The Evolution of the Smartphone: Introducing the Unihertz 8849 Tank 4 Pro**
Smartphones have steadily evolved beyond their initial purpose, absorbing functions once performed by MP3 players, GPS devices, and more. However, the Unihertz 8849 Tank 4 Pro pushes the boundaries even further by integrating features rarely seen in a phone—most notably, a built-in projector.
