The foil is specified as somewhat lower than the cell phone display. This is by design, because the film would otherwise stand out on the edge / replace, because the mobile phone is slightly arched. The measurements are taken very well to this problem! The film covers everything from where they could stick. Left and right on the edge barely missing foil (1-2mm), but you see the film there clearly because they are (very) slightly apart because of the curvature. Top and bottom are missing something more foil (about 3-4mm), but 1) you get used to it very quickly and visually 2) not used to these places to touch, etc. There are no problems with the "back button" or other features. The film is at any point in the path or deteriorates the operability of the mobile phone. On the contrary, the condition is (despite somewhat smaller film) as well as before. The touch screen works perfectly and without degradation. The film is neither too thick nor too thin. The display is well protected by the foil. The stick of the film is very simple. No speck of dust and air bubbles, if you leave a few moments. The first film already has two months and there is still no dirt under it, it is not scratched, and they do not peel off. The film can be a lens cloth good clean so that the mobile phone each time as new shine.
Super value for money. Good quality! Gladly again!
