So I have seen some comments about the Defender causing marks on screen protectors and the glass itself due to the pressure it puts on the top and bottom of the iPhone screen. Apparently this is where the inner polycarb case makes contact with the phone. Has this actually damaged anyone's screen? Or just made marks that will rub off? I am probably returning the case (as much as I love it) because I am worried it will damage the phone, even though I do have a screen protector that covers most of the glass. Thinking the LifeProof might be a better option. Never thought I would consider paying that much for a case but it sounds like the best option. Just wondering if my phone will fit inside with the Best Skins Ever on it. Also wondering if Verizon will sell the LifeProof as I have a 25% discount with them. Thanks.
