Technology has come a long way since. Today’s smartphones sport large touchscreen displays, impressive cameras, and high-tech features like 3D facial recognition. While phones were primarily used for making calls back in the day, now we use them for things like listening to music, browsing the web, playing games, and watching cat videos on YouTube. Back in the day, the main way of using a phone was a physical keypad. This was eventually replaced by the touchscreens we use today. With services like Google Assistant and Samsung Bixby, we can now interact with our devices just by using our voices.
