Clear case and watermarks

[aldo82]

Just got a UAG pylo case and can't get it to fit without watermarks on the back. Probably going to have to send it back. What's strange is I haven't seen it mentioned in any reviews of the case. Is there any way to fit a clear case without this problem as it looks awful? I also have a spigen rugged armor Crystal and it has dots on the inside to stop it sticking to the glass and therefore no watermarks

Spigen crystal has little bubbles that prevent this.
