if I managed to do it without bubbles, too!

He was actually delivered 4 films instead of 3, good start! There is no instruction, I had to take those data with another missed film, another brand. First test, full of bubbles and having one end held too long, it remained distorted and could not stick. Second test: Bingo (3rd in reality with the other film of another brand), the trick for me is: zen, zen: we take off a little bit, it is applied and very very gently, allowed to go up at the end, the film settles quietly, smoothly, on the surface of the tablet, creating no bubble. Proud of my shot and extremely happy with the result. These films are exactly my tablet Xperia Z2, there is a tiny hole for the second another brand of tablet, but nothing, really nothing more unsightly.
