Anyone else having a problem with the screen cover of Defender 5 case? I have bought it few days ago and later noticed that there are some strange colour distortion on the screen cover. First I thought it was just at the upper left corner. But then it disappeared the next day. This morning, it showed up again but on mid section. It's like moving across the screen. If you still don't get what I mean by colour distortion, it's kind of like map contours in rainbow colour in small area. As soon as I found out about this, I've sent an email to the support and they just asked me to send it back to the retailer that I bought from as I'm still in 30 days return period. But, I'm wondering if it's widespread issue or I'm just an unlucky individual. EDIT : No it's not water or anything. I've taken it out and put it back in and made sure of it.
