Protective Film is simple to install, the simplest once well cleaned screen is to start laying the corner with the ports, especially good to take time to not having to remove it and then put it back as it is the best way to have dust bubbles ... if there is only air bubbles, make a cb or other type of plastic card instead of the "song" of cardboard for this purpose and in 2 minute film is placed and the sensitivity of the screen to the tablet remains the same! A couple with protection (case-case) and you are quiet for your tablet! ;-)
