I found out that old phones used to have iris sensors and that they apparently required bezels. I have been told that anything other than a camera requires a bezel. I don’t understand the inner workings of all this stuff so I’m going to need someone to eli5 why they require a bezel. Not why the phone needs to be thicker, I mean why iris scanners and the other stuff need any kind of bezel. I feel like there’s something I’m missing that will be so clear and obvious to me when someone explains it. I seem to have no answer from anyone on this.
