The glass has a very good protection of the actual cell phone displays against scratches. The application is simple. There are mitgelifert alcohol wipes and a soft cloth to clean the screen. Through the adhesive layer on the glass of the protective glass itself on screen liable. Only the adhesive layer on the wrong side was applied by the manufacturer, so that the recess for the front camera is located on the wrong side. However, as this does not impair the function of the camera, I have the items not sent back, but used. Therefore, a point deduction. Otherwise, I would have awarded 5 stars.
