Hi Philip, if your device is still I warranty I would bring it back to Apple and make them fix it for free. In order for us to quote this repair we would have to see your device. If you come in on any day it would take about five minutes for us to determine exactly what it would take to replace the lens. If we can’t use your original lens due to missing or damaged, the replace rear camera lens and labor is $49.99 plus tax Thanks Ubreakifix
I believe they can repair phone with no problem.
