The answer is here, but you just can’t fight physics. Light needs to come through a lens and hit a sensor. There has to be some significant distance, in relation to the thickness of the phone for this to work. Until camera technology advances and somehow produces a comparatively sharp image, we will be stuck with the bump. It’ll happen at some point I’m sure, but there is a whole bunch of tech that will need to change to get there.
My comrade in veganism: this is not the way. Kindness is the only way your message will be heard. If Daryl Davis (a black man) can convince hundreds of KKK members to leave the organization by befriending them and forging relationships, sometimes over years, then you can tone it down and be kind to someone who doesn’t share your views and wants to eat a cheeseburger. Doesnt make them “right”, but your approach just makes you insufferable in the eyes of people you don’t agree with, which is almost everyone. Trust me, I’ve been doing it for decades and you are not setting a good example for the chill vegans out there. Calm down, love people regardless of their differences, there is enough division in the world. Do not turn your ethics into religious fundamentalism. You can control your behavior and you can be a good ambassador. In short: don’t be a smug asshole that thinks they are superior for any reason.
