The film is not fit, an exact and square cut to 1/3 mm too big. Thus, the film is on the edge and begins there with a screwdriver. Also bubbles have formed in various places that are not allowed to move with the credit card as usual to the outside.
It may be that the rough screen surface impedes the application of. What remains is the inferior quality as regards the cut.
Have the film removed again and live without screen protection - so I need not fret over the edges and bubbles me.
