The camera size is already huge in iPhone 14 Pro that it doesn’t sit well on MagSafe Duo Charger wishing that they figured out a way to at least keep the size to how it currently is but it looks like there’s no getting around it. It looks like it’s gonna be bigger than 45mm Apple Watch at this point.
If this were so important it could be solved several ways, the easiest with registration recesses or, better yet, a mountable interface. I’m not buying the line that Apple is beholden to 3rd party bolt-on lenses as the core reason for not producing a flat-backed phone.
