Turn on TalkBack auf Xiaomi
TalkBack reads out labels, buttons and menu items so you can operate a Xiaomi phone without looking at the display. It is part of the Accessibility tools built into MIUI on top of Android and is meant for users who are blind, have low vision, or simply need audio confirmation of every action.
Once TalkBack is active, a single tap no longer opens an app or setting directly. It selects the item and reads it out loud, and you need a double tap to actually activate it. Swipe gestures also change, since one-finger swipes move focus between elements instead of scrolling content the usual way.
To turn it on, go to Settings ➤ Additional settings ➤ Accessibility ➤ Vision ➤ TalkBack, then enable the switch labelled Use Talkback and confirm the permission by tapping Allow.
If you only need larger text or higher contrast, TalkBack is the wrong tool, since it changes touch behavior across the whole system rather than just the display. Turn it off through the same menu path if the phone starts responding differently than expected after someone else enabled it by mistake.
