You will have to take apart and go from the back and what i do (you must be confident first if not get a professional to do it) with that said what i do with all smallparts i put the say iphone down draw around the phone on a small box with nothing inside or nothing inportant and i take apart 2 pieces and draw every part and screws and with a pin needle !$$&* all the screw holes on the box thats in the phone and when i take a screws put i put them in the box exacly were they came out and then you cant go wrong plus if i.have put a 1cm magnet on the top of mini screw driver and they stay on when you take them out ok and with all that said with your camera you will have to take in 2 pieces then unscrew everything to get to the lense if it because its misty try pressing compressed air into the back down threw all the conponants and it might help you out i always say try the simple things that are not even considered first as u could be shock and if you want step by step guild go on you tobe and type in the search and your be shocked they have everything on there from around the world but watch video first then if ok watch and do at same tima and pause till u have done that part i hope this helps as cheers and good luck????
