I currently have the zagg full body invisible shield on, but everytime it sits in my pocket and gets warm it starts to move over the edge putting lint under it. It then looks like complete crap. I had the Apple bumper on my phone for a while but it scratched the aluminum badly. So.. I took the bumper off. In order to keep the zagg shield secure I guess I have to get a new case. I REALLY REALLY wanted to get the element VAPOR but I guess it degrades the signal. So which case should I get that will keep my invisibleshield secured in place? Is there something similar to the VAPOR case but doesnt kill the signal? Thanks for your replies.
