I'm not sure how many of you have encountered this problem, but whenever I make a call if either of my earstuds touch the dialpad tab while making the call it brings up the dialpad and then send out any tones if they touch a number. This means that I'm having to drop the tab back down, only for it to happen a minute or so later. Both my ears have studs too, so I can't simply swap ears. Oh, and I've also tried the screen lock and that doesn't help. Someone has said there is a setting somewhere that will disable it, but I've looked and not found it. Is there any way of stopping this from happening?
