Siri
Siri is often the easiest way to start using accessibility features with iPhone. With Siri, you
can open apps, turn many settings on or off (for example, VoiceOver), or use Siri for what it
does best—acting as your assistant. Siri knows when VoiceOver is on, so will often read
more information back to you than appears on the screen. You can also use VoiceOver to
read what Siri shows on the screen. See .
3D Touch
On iPhone 6s and iPhone 6s Plus, you can control the sensitivity of 3D Touch or turn it off.
Adjust 3D Touch sensitivity. Go to Settings > General > Accessibility, then choose Light,
Medium, or Firm sensitivity to adjust the amount of pressure needed to activate 3D Touch.
Light sensitivity reduces the amount of pressure required; Firm sensitivity increases it.
Turn off 3D Touch. Go to Settings > General > Accessibility, then turn off 3D Touch.
Reachability
Reachability helps you more easily interact with items at the top of the screen on iPhone 6,
iPhone 6 Plus, iPhone 6s, and iPhone 6s Plus.
Bring items within reach. Go to Settings > General > Accessibility, turn on Reachability,
then lightly double-tap the Home button to bring the top of the screen into reach.
Widescreen keyboards
Many apps, including Mail, Safari, Messages, Notes, and Contacts, let you rotate iPhone
when you’re typing, so you can use a larger keyboard.
