How to enable TalkBack/Screen Reader

What is TalkBack?

TalkBack is an Android service that gives spoken feedback and notifications for users with visual impairments. With TalkBack enabled, your device will automatically read the content you touch, select, and activate. While TalkBack is enabled, you will be able to navigate across your device in a significantly different way from the regular mode.

*The voice feedback provided by TalkBack is determined by the language engine pre-installed in the system. This means that voice feedback may not be available for all languages.

Enable TalkBack

Go to Settings > Accessibility, and enable TalkBack.

*If Talkback or Screen Reader is not enabled on your device, your device does not support this function.
