Why does the flash on my white Iphone dosnt work to good?

Me and my boyfriend both have an Iphone but he has the black and I have the white iPhone. But the the flash on his phone works perfctly in the dark. The pictures come out good. But the pictures on my white iphone with the flash come out dark, blurry and not good at all. Is there settings I need to change? Why do the pictures come out so much different if its the same phone?

  • Why do iPhone photos of myself stink, but flash looks good? Whoever I take a pic of myself in the day, I think it looks awful. There are shadows under my eyes and my cheeks look puffy. It also seems like you can't get too far away from the camera. At night with flash, it looks great! Is it better to just use a regular camera for day pics?
  • White & Silver iPhone 5S or White & Gold iPhone 5S? I'm asking for an iPhone 5S for Christmas and I'm not quite sure which colour to get. Black & Space Grey is a no for me btw. Please don't give me hate guys, only need help making a decision!
