I've hadf my kyocera rise through Virgin Mobile for a little over a year now and for the first time, I'm having an issue. My power/lock button has somehow become extremely sensitive to the point where it's a pain. I can slide my finger over the button to activate the lock/unlock sequence and after I press the button the power off option comes up. If I stick a needle under the button, it stops so I assume something is wedged in it. But No matter how often I clean it out with a needle, it continues to mess up. Any suggestions?
