It's funny, I see people cover up the webcam on their laptops all the time, but not their phones. They forget that there's a camera on both sides of the phone.
Webcams in laptops are shitty cameras, and for most people, they're useless anyway (even in post-pandemic era, hardly anyone does conference calls, video or otherwise). Meanwhile, "selfie camera" is like literally the main purpose of the phone for a large chunk of the population.
