Phones have gone through many changes from boxes to tiny rectangles that can fit in our pockets and were always trying to get the new one to impress our friends but I want to look back and view how they were designed and what they were meant to do.
Most of the phones today are focused towards adding new cameras but when phones were older the whole model was focused on creating a more useful for the consumers To want and have a better experience, and if it was good it would be used just like how phones are today but the room for error was greater than what is allowed in newer times. There are many more specifics on https://www.uswitch.com/mobiles/guides/history-of-mobile-phones/ but phones have made many advancements in a small amount of time. It is almost strange how fast we’ve adapted to using them on a constant, daily basis. And going further we keep upgrading them even though it might be less revalutional from when they first came about.
