I've had my LifeProof fre for my iPhone 5S for just a few days. I reinstalled it today to get rid of some dust under the screen from when I first put it on, it took about 20 minutes to get it perfect. I was looking over it and noticed that on the bottom speaker cover, the grey covering looks like it's been worn off a bit and a little bit of the black mesh is visible. I'm not sure if this is normal, or if it would allow water to leak it. I would just do a water test but I don't want to go through another reinstall. Is it just normal wear, or do I really have a hole in my brand new case?
