Galaxy S7 Edge Screen Protector [GS7 Edge] [3D Curved Full Cover] GPEL Accessory Glass by Corning Tempered Glass, 100% Replacement Guarantee, Premium Quality Glass in Korea (Silver) Note: Because the screen protector adds an extra layer of glass, most other cases will not be compatible causing lift and reducing touch sensitivity. Non-compatible cases can cause crack even with low pressure if the case wrap/push too far over the edges of the glass (edges are the most vulnerable area). We highly recommend a case that doesn't wrap too far over the edges or is soft/tolerant then it will work. Your entire screen, edge to edge, will be under another layer of the worlds strongest glass, saving it from virtually anything you could throw at it (except maybe a gunshot).
