30 years ago, a phone like that of what we're using was not thought to be possible. Phones back then were bulkier and were often used sparingly. As technology progressed, so did the appearance and purposes of phones. Instead of just for communicating, it has the features of a camera, calculator, tracker, music and video player and so many others more.

But what should be noted is the evolution of the sizes as well. from large phones to smal ones, it comes to a full circle as we go back to larger-sized phones once again.
