The new iPhones look the same as last year’s models on the outside. But changes on the inside matter, from camera improvements to new sensors that enable quicker access to tasks.
If you want to take a selfie, for instance, you currently have to launch the camera app and hit a corner button to switch to the front camera. If you were taking video before, you need to slide the camera to “Photo” first. With the new iPhones, just choose “Take Selfie” when you press down on the Camera app. The phone makes all the switches automatically.With Maps, you can use 3D Touch to get directions home, find nearby businesses or message your location to a friend. With Mail, go directly to your inbox or create a new message.
Apple Pencil has no buttons. In addition to detecting pressure, it can also detect angle and orientation, allowing it to perform as more than just a simple stylus; it can more closely emulate the behaviors of a pencil, charcoal or brush
