Sensitivity could be better

As soon as I put it on, my screen lost all sensitivity even though there were no air bubbles.

Its really annoying how much sensitivity you lose with this plastic piece

there's glare, specially when there's a pot of light sometimes is annoying to see yourself on the protector.2- my screen probably lost a %0.5 sensitivity, maybe the protector is too thick or perhaps I didn't install it properly

rainbow effect, poor touching sensitivity
