view story

http://forum.xda-developers.com – on my black mist verizon s4, i have some very strange bubbles surrounding the home button under the glass. at least i think theyre bubbles. maybe condensation? not sure what to do here, i got mine on amazon about a week after it was released on verizon. i am running an aosp rom. do you think i could go back to the verizon store if i unrooted and did triangle away and get it swapped out? i also have a aluminum home button (HowTos)
