[Giovanny]

I read this around here and there was a thread from an actual tech from sprint. He posted a diagram that shows the cable connections inside to pro being loose and that is what it causes this problem and there is a simple fix just by using a screw driver used for your sunglass. Is either this or spend two hours at the store for them to fix it for you. I found the link here you go and read the post too it might help. This was posted by "thepoet" one of the sprint techs.
