Step 1: Technical details.
Step 2: Grab stuff!

4. Now make a whole box using hot glue or other adhesive by making the out two side but you have to leave one side which faces the front side of the your mobile phone.
5. Take the side which is left and mark a circle according to the lens radius at a place which face the middle of the screen of your phone (i have marked it little bit on the left side because my screen's center if at the left side.)
6. Cut the hole with blade and fit the lens there and stick that side with the box now.
