The Samsung screen protector is incredibly easy to apply, especially as it is custom cut for each specific handset. Simply give the screen a thorough wipe, line up the screen protector with your phone and gently place down from one side to the other, using the application card to smooth out any bubbles. After application you will notice that the screen protector is virtually invisible. While it's important to protect your screen, it's also vital that the screen protector does not hinder your smartphone use by clouding the screen or decreasing the sensitivity of the touchscreen.
