Hello, I got a strange problem: when I open the dialer and dial "337", the dial closes and goes to home screen. It happens only with "337", not with "7", "37" or "3337". I believe that is some problem on the contact list, but I couldn't find anything. The phone log was inconclusive, and third-party dialers (e.g. TouchPal) works fine. Does anyone have a clue of how to solve it? Thanks!
