MediaDevil's Magicscreen screen protector: Matte Clear edition protects your screen from scratches, reduces fingerprints and screen glare, and leaves no markings when removed. It does not reduce the touch sensitivity of the device screen.
This particular product includes 2 x FRONT screen protectors. It is compatible with all iPhone 4/4S models (including from AT&T, Verizon and Sprint), as they all have exactly the same screen.

PLEASE NOTE: Matte material protectors do produce a slight pixellation of the screen, as this is the natural effect created by the Matte (anti-glare) frosted texture. It is simply an unavoidable 'Law of Physics'.
You will see this pixellation on all anti-glare screen protectors from all brands (many of which are noticeably more extreme than ours). Apple's matte screen monitors (and professional television industry monitors) display it also, as it is unavoidable.
If you require a perfectly 'crystal clear' screen to enjoy the iPhone's retina screen to its full extent, we strongly recommend purchasing our (glossy surface textured) Crystal Clear edition instead:
