           | 
           | Because if using the phone then you need to access the lock
           | screen to use the camera?
           | 
           | That means hitting the power button twice (slowly so you
           | don't trigger the wallet) and then a long press on the
           | camera.
           | 
           | Alternatively it's just a swipe and a tap if it's on the home
           | screen.

             | Fair enough, but then I can think of an even better place

             | iPhones tho, as the physical camera button in the lower
             | right is the easiest and fastest way to get to the camera.
             | 
             | Anyhow, this is all just personal preference, of course.
             | Anyone is free to put a camera icon anywhere they please. I
             | just personally can't stand clutter in my home or lock

           | Half the time since updating to iOS 26 on my 13 mini, if I
           | try to activate the camera from the lock screen the app opens
           | but the camera fails to start and the view just stays black,

               | They are, but the camera stack should be detecting and
