On the iPhone 7, the iconic home button is no longer a physical button; instead, it gives the impression of a button using pressure sensors and haptic vibration motors. In addition, the iPhone 7 is, for the first time, dust proof, water resistant, and lacking a traditional audio jack. Internally, the iPhone 7 has some impressive upgrades, including the A10 Fusion processor, which is about 40 percent faster than the A9 chip inside the iPhone 6S.
