TalkBack 应用
TalkBack is an Accessibility Service that helps blind and vision-impaired users interact with their devices more easily. This application adds spoken, audible, and vibration feedback to your device. It comes pre-installed on many devices so you won't be able to install this if that is the case. It's only activated if you explicitly turn on Accessibility:- Go to Settings
- Select Accessibility
- Enable TalkBack checkboxes
