Speaking of phones covered in plastic, my wife called me after getting her new Iphone..
Wife - "I can't hear anything..it's so soft".
Me - Do you have the volume turned up while in the call?
Wife - "Yes, I do. Seriously, DUH!"
Me - Did you take the plastic cover off the screen?
Wife - "NO! I don't want finger-prints on the screen."
Me - Take it off.. it blocks the ear piece on the phone.
Wife - Oh! .. OH!.. Ok, I can hear you now.
I hate to admit this, but when I got mine I went to the grocery store, called the wife to make sure I got everything and couldn't hear a thing! I promptly went back to the store, "This things a piece of crap! I can't hear anything!" Yeah, the clerk peeled the plastic off, "There you go sir, that blocks the speaker." DUH!
