Unfortunately, this protective film has a lack of recess on the display (at the top right next to the Höhrerlautsprecher is a matter oval dot on the display of the Lumia 610). This is when a call made by dialing the display goes dark (such as when the phone at the ear, and the backlight turns off), consequently, can the Lumia 610 is no longer operate. One is forced to remove the battery. First I thought of a malfunction of the Lumia - after removing the foil, the device worked perfectly again. The error is repeated after applying the film to the display - a Fehlfunktin the Lumia is therefore excluded. Too bad, because the installation is running smoothly and without bubbles to 100%. In other features, there are no complaints, but as calling the basic function must be already given. This is the case of the film delivered me not the case. Since I unfortunately can not assign null stars here I must assign a star.
