My 16P screen protector package came with a little protector for the bumped out cams. Looks to be similar glass but maybe even thinner. The darned thing broke for no reason... not dropped, never really set down hard. There is another one in the kit but IDK if we really need them. The cams seem to have a small relief that keeps the native glass from scratching when set on a flat surface. Does anyone else have and use one of these?
