Make full use of 3D Touch shortcuts
Quick app actions
For many apps, a firm press on their Home screen icon reveals a list of actions. In some cases, it also shows a widget with info or additional actions; if you refer to a widget often, there’s an option to add it to iOS’s Today view.
Switch apps
Instead of double-pressing the Home button to open the app switcher, press firmly on the left edge of the screen. Alternatively, press firmly while swiping to the screen’s right edge to go back to your previous app.
Control Center
Apply 3D Touch to an icon in Control Center’s bottom row: pick from flashlight strengths, start a1, 5, 20, or 60-minute timer, copy the last result from Calculator, or jump into Photo, Selfie, Video, or Slo-mo camera modes.
