+ Display is significantly easier to read than without foil (eg Google Maps Navigation) in the sun
+ Brilliance suffering in my view in any way (only deliberate matt effect)
+ Haptic / HMI-feel I find with foil also better than on the original display
+ No longer a problem with fingerprints
For the attachment I have two tests used. Thanks to the ingenious scotch tape tricks of Brüno in the 2x mumbi screen protector Samsung Galaxy Note screen protector (ready set piece scotch tape and possibly in the course of attachment to the film adhering dust particles so easily removed) sits the 2nd film now absolutely perfect and without bubbles. This tip should be included in the manual ;-)
