I recently purchased the Nano Slim glass protector for my S4. Application went well considering my shaky hands. Dropped the protector onto the phone and got a perfect fit. Then pushed out one bubble at the top and was pretty proud of my new protector. Was showing it off to friends who also have the S4. I have had it on for about 2 weeks and I noticed the top edges, left and right are looking like they are lifting. No seal. I was recently in NC on a trip and there has been considerable rain and humidity. The phone was never exposed to the rain. I am wondering if the humidity could be causing this effect. Very disappointed after I did what I thought was such a good job of applying. I cleaned the screen well before applying, etc.
