I bought the black silicone case from Verizon yesterday and it seems to fit right, but somehow it keeps messing with the volume on my phone. I have to hold the volume down button until it is all the way down or it goes right back up and if I tap the volume up to turn it up just a bit it keeps going all the way up to the highest setting. Does that make sense? Anyone else having this issue or did I just happen to get a messed up case?
