I guess its suppose to take high quality pcitures and videos.

"High Quality"?

Consider this: your starting point is a TELEPHONE - a gadget designed for SPEAKING, not photo taking.
It has a super TINY sensor and tiny lens, and very limited ( or non existent) options.

Now you're clipping a little plastic "lens" onto that which will add more distortions and take a way a lot of light.

I'm not sure how the end result could possibly end up as "high quality".
