Lone Star has earned only by the kind support of the dealer this film. After I complained to a mail the shortcomings, I have a few days later an "improved" get film sent. This was indeed larger, the problems with the microphone and the sharp corners have remained.
So overall it has not even managed to mount the film, so I can make no statement about the other properties.
The purchase is not recommended!
EDIT 24.11.
Meanwhile I got the second revised version of this sheet sent. Behold, the manufacturer has taken the criticism to heart apparently.
The corners are now rounded and the size is correctly tailored to the screen. Also recesses were now for the microphone and even added the Brightness / distance sensor.
When installing there are still weaknesses. There are dust particles between the protective film and the plastic carrier. It can therefore not be avoided, that precisely these particles are at the end between the film and the screen. An error in attaching can I exclude largely because this is not the first protective film by far that I have attached.
As the scratch resistance looks in everyday use, remains to be seen.
All in all I would therefore now give a 3,3 of the foil in the price / performance range.
