Tempered glass screen protectors, offer maximum protection for your screen, and will absorb and disperse the shock of a direct impact to the glass on the screen, often this results in the damage of the screen protector, but it's a lot cheaper to replace the tempered glass screen protector than the display assembly. However Tempered glass will add a few mil to the thickness of your phone or tablet, and when you add your phone to a case, this can be enough to cause it not fit if the case is tight, or if your case goes over the one button, this can cause issues with the usage of the button causing you to have to press extra hard to make it work.
