those are just on there with an adhesive, heat and pick it off. be careful to not damage the bezel if you don't want to replace that as well. Don't let your tool knick the camera lens or you'll have focusing problems afterwards. be sure and use a quality adhesive to put the new one back on and you're good to go. I don't know if an s6 lens will fit or not, but if it fits-it ships. you're good to go, theres nothing special about them.
