My impression after the colors and the brightness of displays remain protected with foil. The touch capabilities are not affected at all.
The installation is relatively simple, but you have to be very careful and cautious in order not but a speck of dust is trapped. Here's a bit of flair is required. Everything you need to (mainly micro-fiber cloth) is included. If the film is first installed, you can use the phone in all its quality and with a clear conscience for the protection of the display on.
However, I find the price of the film from 4.49 a little too expensive. Therefore, a star deduction. Otherwise, top product.
