I have this problem with my Meizu MX4, the camera is great but this is a real problem for video. This is a key video camera function not a background bug, this needs to be fixed urgently. The bug report has been open since 2014, and still only has an importance of Medium, surely now we have real hardware being sold this should be changed to high and included to the list for OTA-9.
Thanks Dave H

This problem is caused by the camera backend reporting no zoom capabilities when the phone is switched to video recording mode.
This has been reported as bug #1517050

The UI is simply (and clumsily) reporting that it can't zoom.

The short term fix is probably to disable the zoom UI entirely when no zoom capability is reported by the backend (possibly with some indicator that zoom is unavailable, to prevent the user to think that pinch to zoom is simply broken)

Testing on meizu devices welcome.

Hi,

Thanks for fixing the pinch to zoom function on the MX4 with OTA-9
All working fine now. Also very happy with the new picture resolution
settings.

Great work,

Regards

Dave
