You can also enable the TalkBack feature using the volume rockers on your Android smartphone. To do this, simply hold down the volume up and volume down buttons simultaneously for 3 seconds. If you haven’t already enabled this shortcut, your device may prompt you to do so; in that case, simply tap through the menu to confirm that you want to enable it. Once you’ve enabled this shortcut, you can turn TalkBack on or off by holding the buttons down for three seconds.
If your device did not prompt you to enable the shortcut, you must do so through TalkBack settings.
You can access a variety of options by tapping Settings from the main TalkBack / Voice Assistant page. You can, for example, change how much of your screen is described and how you speak about lists; you can also enable vibration feedback and customize your menu. If you intend to use TalkBack on a regular basis, it’s well worth your time to customize it here.
