On the instructions of the "inner packaging" of paper, which surrounds the protective glass itself, it is claimed that it was encased the protective glass with two protectors. These two cases are nowhere, the protective glass is only "protected" by a protective film. So you have to do a step less than described on this further instructions. This creates confusion and therefore a point deduction in the evaluation. It would also be helpful to provide the instruction in German.
The protective glass itself can hang up bubbles and light, it then attaches itself almost automatically on the phone's screen without printing. The operability of the display work perfectly then. The fit of the recesses is not exact, but okay.
There were 2 ordered protective glasses. Were supplied in addition to the two protective glasses per packing a microfiber cleaning cloth, a sticker, which allows you to remove dust from the screen. A pack also contained an alcoholic cleaning cloth that was missing in the 2nd pack. Fortunately in the household such Brillenputztuch (disposable) was at hand. Otherwise, the lack of this option during the installation would have been annoying to clean the screen properly.
