The back flap rotates to hide and reveal the sticky pad for use, and also attaches tightly to the case to allow you to set angles for your shots.
Over time or with impact, the hinge may become looser. Cracks and breakage are usually the result of fall damage, which Podo Labs does not cover under our warranty policy.
Take care whenever removing the back flap. We recommend that you do not take the back flap off for any reason!
