Put a screen protector on *flawlessly* the moment you take it out of the box. This must be done in a space station zero gravity atmosphere situation to avoid trapped dust particles and bubbles in screen protector application. Preferable if screen protector is made out of an atom thick diamond see through or an unknown material yet discovered.
