In the interest of objectivity...

I have just tried it. The first thing I noticed was that is does not work. Pressing the volume buttons in Camera regulate the volume, as expected. I thought to myself, is there some setting somewhere that I missed? With Jolla you never know, since they like putting settings all over the place instead in the one place where they belong, the application itself.

But it turned out the problem was elsewhere. The volume buttons work like, well, volume buttons when Camera is in the video mode. In the photo mode, they work as a shutter trigger.

So much for consistency.
