First make sure you have the correct viewer profile:

From the Google Cardboard app, tap Settings > Google Cardboard.

If you're still having trouble after you've verified your viewer profile:

Make sure you're using an approved app. Take the phone out of the viewer to look for these items on your screen:

  • At the bottom, there is a Settings icon.
  • In the center, there is a vertical line.

If you can see the vertical line while using the viewer:

  • Slide your phone left or right until the line disappears.
  • Turn up the brightness on your phone screen.

To focus better:

  • After your phone is properly set up inside the viewer, look at an object that is far away.
  • Close your eyes and bring the viewer up to your face.

  • Use both hands to hold the phone more firmly inside the Cardboard viewer.
  • Remove the case if you have one on your phone.

My phone keeps going to the home screen[edit | edit source]

  • Close and reopen the Google Cardboard app .
  • When you close the flap over your phone, don't close it too tightly. If you push too hard, the flap could press the phone's "home" button.

The button doesn't work[edit | edit source]

If you have a button at the top of your viewer:

  • Look into the viewer and find the tab that is meant to touch the phone screen.
  • Press and release the viewer button. Make sure that the tab is:
  • Moving back and forth.
  • Not pushed forward so that it is in constant contact with the phone screen.
  • Not stuck in a forward position.
