So, now i have a iphone 4s from my 4, i have a few cases and most of them fit just fine... but anytime i take a picture at night with the case on and the flash on the picture gets washed out. either its the whole picture or just a corner of it... is the flash like more powerful ? do i need a different case? i tried it with my otterbox and it was also washed out. anyone else have this problem? p.s when the case is off the picture is fine with the flash on at night.
