Halide 1.5: How I learned to stop worrying and love the Notch.
Eek, the Notch. When we set off to redesign Halide for iPhone X, we had to do something with the notch. Insetting the viewfinder would be bad; you'd lose visual area of what you are photographing.
Initially we had controls up there but we ended up with this solution, showcasing functional non-interactive readouts in the 'ears'. I think it plays to the strengths of the screen, and we now really use every pixel on the screen that's available.
