Cool, thanks for the response. I just did a quick sink spray all over the front, back and sides. Took the case apart and didn't have any water anywhere. I'm not going swimming with this case, so I think it'll be ok til I get my replacement or refund. I just want it to be proofed from drink spills and maybe a quick dunk in the sink or something if my son throws it somewhere its not supposed to be.

(Quoting myself)... I think it's a small alignment problem. I tried unlatching the charging door cover and clicking the corner back in place. Then holding the corner closed, close the charging door. It seems to stay latched this way. I don't know if it'll hold though.
