Even with an infinite wealth of precautions I could not avoid the presence of qqs air bubbles, particularly on the edges, whereas normally it is the easiest to make them disappear, and around the front camera. I used a credit card to apply the film and remove air bubbles. The stickers that allow equip 2 film of the film leave traces on the film, and this on two films used. I bought this film to save shipping costs because I also bought a shell of the same dealer. I regret a little. Fortunately, the touch, it's perfect.
