OK, this is hard to explain, so bare with me. S6 Active is just a few weeks old. Felt great in the hand until now. Now, I can feel the outer rubberized casing slightly separating from the hard internal phone body. The location it's doing this is just below the volume rocker. When I press the area below the volume rocker, I can feel the outer rubberized casing moving, and can even hear a clicking/popping sound. I think the adhesive that holds the rubberized casing to the internal structure has become unstuck. Is this common? Is it going to get worse? Will this compromise the waterproofness? Is my guess as to what's happening accurate? Anything I can do to fix it?
