I’m going to chime in that I think the dedicated Camera Control button is the most important addition to the iPhone in years.
This isn’t just from having the new iPhone 16 Pro for a couple weeks now; it’s from decades of NOT having it. Several years back, they made the camera FAIRLY accessible by allowing us to swipe left from the Lock Screen. This was functional, but was no help when the phone was both unlocked and had any app running, so your dock was also inaccessible. And the Control Sheet was still more friction and delay than desirable when you had a quick pic you wanted to take.
And there was no way around this problem. We struggled with it for years. Finally, the top dogs at Apple came to their senses and granted Camera app a promotion that is reserved for only the most royal monarchs of iPhone Features: a dedicated button.
If offers another plus, too. It overrides what you’re touching on the screen: you can touch or multi-touch your screen, and that button will still launch Camera and take a shot. When your hands are full and you want to take a selfie, that’s a big help, because sometimes it’s hard to ensure there’s nothing touching the screen.
And it’s useful for another reason: shooting a photo when you can’t hold the iPhone at an angle where you can see the screen (or the on-screen shutter button) like trying to reach under the sink to get a pic of its Model # or 1000 other examples. In fact, you can now easily take a selfie with the much-higher-quality (and less distorted) back camera for the first time: point the screen away from you and the lens towards you, and press the Camera Control button twice
For the latter facing-away-from-you application, you COULD use the volume control buttons. But let’s be honest: who remembers whether it’s Volume Up or Down, and then who can find the right one when it’s photo time? And now that we have the Action Button next to those, it’s even harder to figure out which Left Side button is which. But the Camera Control button is on the less-crowded side, and is recessed so you can’t confuse it with anything.
This is the most important iPhone usability and productivity feature that I can remember in a long time. It’s so fundamental and obvious, that it has and will go mostly uncelebrated. In fact, it’s just getting us back to where we were 60 years ago with consumer cameras. But in 2 years, everyone will scratch their heads about how they tolerated fiddling with apps in order to take pix.
