vivo mobile green box The "green box" you are seeing on your Vivo phone's screen is  likely the  TalkBack  or  Screen Reader  accessibility feature being enabled . This feature is designed to provide spoken feedback for users with visual impairments.   When TalkBack is on, standard touch gestures change: you must  single-tap  an item to hear it read aloud, and then  double-tap  it to select or open it. You also need to use  two fingers to swipe  on the screen to scroll through pages or menus.   How to Turn Off the Green Box (TalkBack) Use the special TalkBack gestures described above to navigate your phone's settings and disable the feature.   Open Settings : Locate the  Settings  app icon and single-tap it. You will hear spoken feedback. Then, quickly double-tap anywhere on the icon to open the app. Navigate : Use  two fingers  to scroll down the screen until you find  Shortcuts & accessibility  or simply  Accessibility . Single-tap to highlight it, then double-tap to enter. Find TalkBack : In the accessibility menu, look for and open the  TalkBack  option using the same single-tap/double-tap method. Disable : Tap the  Use TalkBack  toggle switch to highlight it, then double-tap to turn it off. A confirmation pop-up may appear; if so, select  Stop  and double-tap to confirm.   Once disabled, your phone's touchscreen should return to normal functionality.   If the Issue Persists If the green box is a permanent, static line or area on the display and not a navigation aid, it may indicate a hardware issue or software glitch:   Restart the Phone : A simple restart can often resolve temporary software glitches. Check for Physical Damage : The issue might be due to a loose display connection from physical pressure or water damage. Contact Support : If troubleshooting steps fail, the display may need professional inspection or replacement. You can contact  Vivo customer support  for assistance
