I just hold down the dedicated camera button until it starts taking video. Sometimes you can see the edge of my pocket at the start of the video. One day, phone manufactures will start producing useful hardware again.

Dedicated camera button is one of the best decisions Microsft ever made.

Bet ya if your phone was locked down in the typical corporate IT security way (pattern lock is out, need to use a numeric pin, it needs to be at least N digits long, entered correctly before you can do squat with the phone, gods help you if you screw it up too many times), you couldn't.

There's also startup time once you've launched the app. Even on a modern iPhone, that's a second or two before the shutter iris goes away and presents you with the viewfinder screen.

The Glass demos I've seen make it instantaneous.

Making a quick pull of ... something ... out of your pocket around police officers does not strike me as a good idea.

Wait, people keep their phones in their pocket instead of their hand all the time? mind = blown
