Does not work with new I-phone

If I had giant hands I might be able to actually get a reading. But I have small hands and it is IMPOSSIBLE to cover the lens AND flash at the same time (and which lens am I supposed to cover?…you show a camera with only one lens in your demo…how old is that?!). I spend 20 minutes with the stupid thing stopping and starting and never actually get a reading. Too bad I can’t get my money back!
