If anything an under-display camera would be even better for privacy, since the pixels in front of the camera would need to be turned off for there to be any sort of image quality, so having the display on acts as a privacy shield for the camera.

So what if the display is off you say? Then you can still spot the lens easily as if it’s just a regular camera. Just cover it up when you’re done using the display and it’s pretty much permanently blocked.

Most people have Hey Siri activated and they’re doing just fine.
