After receiving the sheets (3x front and 1x Back) I am, however, very enthusiastic. The application was very simple. An illustrated guide describes the procedure very closely. The Bubble Card helps push out any bubbles arising. The recesses of the film fit exactly (home button, camera, speakers) but the foil covers the display is not completely off. The result is an edge of about 1mm around. But this turned out to be advantageous because the film thus adheres better and not easily be detached from the display again. Use the front and back sheet together with a black Mumbi Bumper. The bumper includes exactly the 1mm gap between the film and the display frame. By Car, the film does not stand out on the display. Only if you look closely you can see the display foil to the recess for the front camera.
I am thrilled and can each these films - especially with the Mumbi Bumper - recommend.
