You place your phone in your hand (palm side facing up and flat), with your index finger essentially resting near the bottom part of the camera plateau bump. This translates to better weight distribution (vs your pinky, if you rest your phone on it, overcompensating which leads to hand fatigue). Both Spigens have wider camera lens cutouts that reveal the base of the lens/rims. Worst out of these is the Skinarma - it has pretty good raised edges but the whole camera plateau is exposed. Best Protection: Skinarma.
