When my normal film stock exhausted I bought the right product for my use -I bought the atFoliX FX-Antireflex. Nothing to say, the light sensor is not covered and it is a good point for those who have the brightness of the screen in automatic mode like me. RAS for tactile sensitivity, an area where Nokia excels long ago. I did not notice any differences in "normal" mode for touch sensitivity in my daily use. Practicing mountain biking and road cycling I also use my smartphone tactile sensitivity mode "high" to use it with gloves and this film does not change -this still works the same.
The most important point is the anti-reflection. Glossy screens are unbearable to me and there it really helps overcome. I can understand that the grain of the film bothers me some, but those are reflections that bothers me, not that my screen is touched granular or my image becomes grainy same -I like that.
