I read a tip somewhere a long while back where someone suggested putting a piece or two of tissue paper over the flash to work as a make shift diffuser. It would allow the flash to be bright enough but soften up the really bright cut that LED's can have. I havent tried it since I have rarely needed my camera yet, but when the time comes I might try this tip out. It would work especially well with my phone and case since it would hold in the tissue papers against the LED without any attaching. You could also put the tissue papers under the battery door then install the door over top, but it might hinder the door from sitting flush.
