Description of 12x Zoom Lens:

- A zoom lens is a type of lens which can reduce the distance between the object and the lens by its magnification. In this case the 12x zoom lens can reduce the distance by 12 times.

Steps:

Fix the Clip in the center of the camera without the lens.
Fix the zoom lens on the clip.
Now rotate the focus ring to get perfect focus on any subject.

Tips:

To get a blurry background distance between the object and the lens must be lowest.
The minimum focusing distance of the 12x lens is approximately 1 meter. So, maintain the distance between your lens and object to 1 meter so that you will get a very nice blurry background.
To get the lowest focus rotate the focusing ring to the leftmost side.
Place the object at the middle of your photo to get rid of the lens distortion.

Samples:

Disadvantage:

Like everything comes with pros and cons this lens has also some disadvantages.
The quality of the images will be reduced drastically due to distortion. it is true for all zoom lenses for phone. However, you can improve the quality using the image editing software or app.
Images will have chromatic aberration. You can remove that using photoshop or any advanced software.
Sometimes you will get blurry images due to wrong focus or shaky hands. A tripod is highly recommended for that.
