Just tried to swap for a light leak and they wouldn't let me. I had swapped the day earlier for a different problem and the refurbished iphone they gave me had the light leak. The guy was giving me a hard time about it and said that he didn't think it was a "problem", but instead "normal variation". He said that 4 out of the 5 iphones he looked at in the back had the same issue. I called him out on a few things, but there isn't too much to do if they just won't do it. I would hope for a little better standardization for the amount of money you pay for it
