Q: Videos in Foto's can not be played after iOS 9.2

Hi there Groningen10,

Welcome to Apple Support Communities.

If I understand correctly, there's an issue with the Videos and Photos app not opening on your iPad Air. Try taking a look at the article below and running through the general app troubleshooting tips that it provides.

If an app you installed unexpectedly quits, stops responding, or won’t open - Apple Support

Restart the app

Close the app and open it again.

 

Restart your device

Turn your device off and back on.

If the issue persists, try restoring your iPad as shown here:

Cheers.
