When Android TalkBack is turned on, you get a spoken description of whatever you touch, select, or activate on your device.
By default, TalkBack is turned off. To turn it on:
From the home screen of your mobile device, tap Settings > Accessibility > TalkBack, slide to ON, and tap OK.
Important: When TalkBack is on, you’ll need to open your voicemail in a separate Lync view in order to play it back. Here’s how to do that:
Tap the Voice mail icon on the top of the screen. This will open a new view in Lync.
Select the message you want to play, then tap the Play icon to listen to the message.
To exit voice mail, press the Back button.
