As already clarified, the camera module has a lot of mechanisms in place. This is because the concept of our flipping camera goes far beyond what has been implemented before on the market. You may or may not argue that this is "too advanced" but the capabilities are there and the implementation as a result.
When the camera retracts itself back into the cradle - you may notice a double "click" very faintly. This is to ensure the camera is pushed back all the way in. Same thing when you "unlock" the screen, the system makes the same check again and you can hear that faint "click" when the gears engage to make sure the camere is where it is supposed to be.
For example, we allow a free-moving non-locking mechanism, meaning that the camera is never "locked" in place by any gears or brake - so you will notice that when it is "flipped up" you can still push it around. This helps greatly for durability as we prefer it to move when being forced rather than risk a breakage.
