@totalsonic thank you for the answer,
as a web developer of webapps, my question was meant to understand the limitation of MorphBrowser in the context of custom webapp on Ubuntu Touch.

Hello to VollaPhone happy users,
I am happy with VollaPhone Ubuntu 16.04 (OTA-18),
but one of the feature I would have expected is to be able to use the camera in Morph Browser (also called WebCam),
I would like to use the camera in web sites to scan QR Code generally accessed in javascript using navigator.mediaDevices.enumerateDevices() or navigator.mediaDevices.getUserMedia()
I was thinking it may need some authorization at the level of the settings of the browser,
so looking in Morph browser, Settings menu, Privacy and permissions, Camera and microphone, the page displays 2 entries "Microphone" and "Camera", but there is no checkbox or slider to activate authorization.
Anyone could confirm if it specific to VollaPhone (UT) or is it general to any device ? testing camera using Morph Browser can be done here:

Any directions to solve this issue would be appreciated,
or any timeline if this a feature to come in future releases.

Jyv.
