Still not sure why something like that is limited to just certain devices.I never understand the change of pressing the shutter button. For a decade (?) or so, the smartphone industry have taught users that pressing the shutter button will result in burst shots. Video has always been a separate button or mode for obvious reason.
Now who had the smart idea at Apple to change this behavior? I mean why? I don't see anybody complaining that they expected video recording from a photo taking mode.
