Camera preview stays black

Hello!

Ask me any question about Lympik.

Please be as specific as possible so I can help you better.

How do I upload data from Oculus to the Lympik web app? What do I need to consider before timing myself with Chronos? How can I analyze Oculus data? Why can't I see any results in my activity? How does video analysis work? Why are my times incorrect? How can I edit my privacy settings? How does payment for the software work at Lympik? How do NFC chips work? What should I do if my Chronos device has no reception? How do I upload data from Oculus to the Lympik web app? What do I need to consider before timing myself with Chronos?

If the camera preview appears black when you open the app but no error is shown, this is usually caused by iOS reclaiming the camera hardware for another app.

Quick fix:

  • Swipe up from the bottom to open the app switcher
  • Partially close the Lympik Recorder card (don't fully swipe it away)
  • Return to the app — the preview should recover automatically

Alternative fixes:

  • Fully close Lympik Recorder from the app switcher and reopen it
  • Restart your device if the issue persists
  • Check camera permission in Settings → Lympik Recorder → Camera
  • Make sure no other app is currently using the camera

The app also has a built-in automatic recovery that detects this state and reinitializes the camera. In rare cases the recovery may not trigger - that's when the manual steps above help.
