The Nexus 6p is supposed to have some cool features dealing with burst and slow-motion (high frame rate) capture, but all my searches for how to use these features are turning up an explanation that the features are there, but not how to use them.
It must not be too difficult, because I inadvertantly took a burst capture when I was trying to take a single picture. A bit of research suggest that "holding down" the shutter button (volume button, apparently) shoots a burst, which is unfortunate if I just want to make sure I really pressed the button and only want a single picture. I can't find out a way to disable this if I really don't want a burst of images at a particular shoot.
But I can't figure out at all how to use 120fps or 240fps capture, or even how to choose the frame rate. How do I do this?
