Navigating HTC One remix with TalkBack
Use TalkBack if you need to navigate HTC One remix by spoken feedback.
When you touch the screen, HTC One remix vibrates and gives you an
audible response so you know what you are touching.
Not all languages are supported.
Turning TalkBack on
1. Go to Settings, and then tap Accessibility.
2. Tap TalkBack, and then tap the On/Off switch.
3. Read the TalkBack disclaimer and then tap OK. You'll be prompted
to enable Explore by touch, which provides an audible description
of what you're touching on the screen.
A short tutorial explaining how to use TalkBack will begin playing after you
turn on TalkBack.
TalkBack works best if you turn off auto-rotate and turn on
Explore by touch.
