Hidden but found on the iPhone

I’ve had an iPhone for a year and a half now, and I’m still finding things it can do, here are a few things that I have found:

  • Pressing the Home button twice quickly takes you to your favorites (this can be configured in the setting)
  • Press Home button while pressing the on/off button causes a Print Screen
  • If you continue to home the Home and on/off button it will perform a reboot of your iPhone
Have you found any more features that I have missed?
