Question 1 : Pop-up camera?

I had an idea, and the more I think about it, the more I like it.

What do you think about a pop-up camera module? First I thought pop-up camera were silly. First because there is a motor, which can fail, and because they look easy to break.

But then I thought, what about a manual pop-up camera strongly built into the aluminium case? I found there is a big advantage about manually poping the camera with a mechanism like clicky pens. Meaning when you click on the camera module it will go out. Click again and it will stay inside.

The big advantage of this is that we can add an electrical contact, such that the phone knows when we opened the camera. Which means that you pick your phone in your pocket, click on the camera, and that will automatically unlock the phone and open camera app. Whereas on traditional phones, you need first wake the screen, then slide up to open camera.
So with the manual pop-up camera you need only 1 move to take picture.
Whereas on traditional camera you need 2 moves.

Also it let us use the main camera as both front and rear camera. Rather than having a lower quality selfy camera.

And the other big advantage is that we can have 2 beautifull full screens without punch hole, waterdrop or notch.
