Innovation is going in the wrong direction. I'd love if smartphone providers were building cameras with fancier camera covers, that the user could control. The last thing I want is a camera behind the screen that I can't even see.
And yes, I know that some have suggested that this will fix the uncanny valley effect during video calls by allowing viewers to look directly at each other rather than upwards, towards a camera. This will not fix it. There are other things causing this effect, such as latency, lighting, lack of a view of full body posture, etc.
