How to use accessibility tools on mobile
There are a lot of great features right on your smartphone. Both iOS and Android provide many tools to help you access what you need. For example:
VoiceOver for iOS (Apple) and TalkBack for Android are the screen readers that come built-in. To turn on VoiceOver, use Siri, or go to Settings, then Accessibility, and then turn VoiceOver on. You can set the Accessibility Shortcut to VoiceOver from the Accessibility page in order to triple-click the Home button to toggle VoiceOver on and off. TalkBack has a similar feature.
Zoom, inverting colors, Color Filters, and Reduce White Point are other features and tools on iOS that you can use. These are also available through the Accessibility Shortcut.
