hey guys I've been having this minor issue with my 8310. starting about a few days ago i realized my c/9 button doesn't work great. there would be times where it works perfectly and there would be times where it doesn't work and i would have to put more pressure on it. does anybody know how i can fix this problem? or is this a defective device? i have never spilled anything on it and i keep my phone in my back pack and not my pocket. i've tired blowing on the keys but no luck.
