First, we must first separate the thickest part of the thin part, which will land on the mobile screen, so far, okay, this is after here is complicated. We must take off the small strip of white adhesive paper, flexible transparent film and a part time, provide a good quarter of an hour to remove the traces of glue, left by the white sticker, not with the small beige cloth but rather with a drop of dish soap and then wipe with a kitchen towel, and finally with beige cloth to remove scratches microphones cloth. The only consolation, laying on the screen is very easy, but even after you clean the screen and push it with the small beige cloth impossible to remove the bubble areas. Beautiful junk to remain courteous, although I do not think using the other 5. A product I do not recommend.
