TalkBack is an accessibility feature that helps people who are blind or have low vision to interact with their Android devices using touch and spoken feedback.
When TalkBack is on, items on the screen are outlined with a focus box, and the device gives audio cues about what is on the screen. Instead of typical touch interactions, you can navigate the device through TalkBack gestures. To learn TalkBack basics, watch a video.
Tip: To turn on TalkBack, options vary based on the device manufacturer, Android version, and TalkBack version. The information below applies to most devices, but you might experience some differences.
When you set up your phone
During phone setup, hold down both volume buttons for a few seconds to turn on TalkBack. You can continue using the volume keys as a shortcut to turn TalkBack on or off once you’re done setting up.
Tip: To permanently turn off the volume key shortcut after setup, go to Settings
