By cons, to such a form for the toughened glass screen is really neglected. There are 5 steps to achieve translated into an English that even with my dictionary I did not understand. So, as it was my first experience with protection with electrostatic assembly, and I screwed up my protection was dirty (unable to get back unfortunately). I put it anyway because it protects the screen but hey I'm pissed off.
To sum as has been said before, just clean the screen of your phone with a wipe with glasses and a little windshield washer for degreasing, remove the protective film of the tempered glass protection and apply. Do not wait, paste this thing as quickly as possible because it catches dust at great speed and multiple steps in the manual will change nothing.
So for the record and because I lost it because of my protection, I note 3 ***.
