If Android reads items aloud and outlines the item you touch, TalkBack is likely on. If the volume shortcut is set up, hold both volume buttons together for a few seconds. You can also open Settings → Accessibility → TalkBack and turn off Use TalkBack. While TalkBack is active, tap once to focus, double-tap to open, and use two fingers to scroll.
01Try the shortcut that is set up on your phone
Section linkHold the volume buttons together and listen for confirmation. If an accessibility menu opens, choose TalkBack. If you have an on-screen accessibility button assigned to TalkBack, tap it once and then double-tap. If Google Assistant is set up, try asking it to turn off TalkBack.
02Get from the lock screen to Settings
Section linkSwipe up from the bottom with two fingers to bring up the unlock screen and enter your PIN or pattern. Once you are in, swipe down twice from the top with two fingers to expand Quick Settings. Tap the Settings gear once, then double-tap.
03Turn off the screen reader in Settings
Section linkScroll with two fingers to find Accessibility. Tap it once to select it, then double-tap to open it. Do the same for TalkBack, the Use TalkBack switch, and the confirmation button. To check that it worked, tap an app icon once. It should open without first reading its label.
04Keep TalkBack available without accidental launches
Section linkIf holding the volume buttons keeps turning TalkBack back on, go to Settings → Accessibility → TalkBack → TalkBack shortcut. Disable the shortcut or change how it is triggered. Shortcut choices depend on the device and Android version.
