Unfortunately, the display reflects as strong as without foil. The also available antireflection film (2 x mumbi Screen Protector Sony Ericsson Xperia Mini Pro Screen Protector "anti-reflective" Anti-glare) but unfortunately affects so negatively to the image quality that I'm back changed for Crystal Clear.
Another tip for mounting:
Dust is your enemy! Necessarily (!) Work in a dust-free environment!
Thoroughly before gluing the display clean (Brillenputztücher or cotton towel and isopropanol careful with alcohol -. The denaturant may cause streaking.
The congruent positioning of the film is the most difficult part. Dry is hardly possible. I have therefore previously been wetted with distilled water, the display - it is possible to move the film to the film of water. Then, the film with a towel from the inside out firmly press (careful not to slide the foil again).
Protip:
Distilled water, therefore, because it is "clean" (dust, lime etc), and of course, very little - not flood the phone. I have 1 liter of water mixed in a spray bottle with about 2-3 drops Spühlmittel - which is also great for final cleaning of glasses.
