I am trying to repair my Pantech Matrix (speaker) and I cant seem to get the back off. I have removed the battery and I can only find 4 screws but there seems to be 2 more holding the other end. How do I get to those screws (if there are such screws) or does this end snap together? Don't want to pry and damage the plastic.....Thanks for any help
