Unlike more expensive films, these come without cleaning cloth or spatula. It contains two films, with protective film on the adhesive side. The instructions are in German and in sufficient detail. You know back on the use of a debit card as a spatula and how to remove any bubbles. Clean one does the display, for example with a microfibre cloth. The best places to the first film with a protective film on the screen in order to see how much distance needs to be up and down, so that it is positioned centrally. Then clean the display and remove the protective film to one-third. Top start to the recess and pull on. The protective film is stable and thus the film can easily slide down and stick in one go. It nevertheless proceed slowly and press at blistering with the card outwards. Do not leave the bubble, it is an impurity. Then simply return some time and clean.
Geklapt with me on the first try. The film is well located and has the feel better than a "naked" display. For the mobile phone in this price range a very adequate film. For a 600 flagship, I would spend more on a protective sheet.
