I got a problem with the volume key of my BB, and i press up it doesn't work but when press down it's working as normal, so if there any solutions with this problem?
Have you swapped any hardware parts recently? I.E. Bezel?
I have the same problem after I changed out the bezel on my bold. It was simply not making a proper connection when pressing the button. Disassembly and re-assembly fixed my problem.
