Weird Default Dialer issue - unresponsive but can make calls using other dialer, etc.

[chitanjun]

Hi - on samsung galaxy note 2, can do everything, text, email, etc. Can even make calls using another dialer I installed but whenever I try to use the default dialer the screen flashes white for half a second then nothing. It doesn't hang... can still use every other feature including press the dialer again and it just flashes white again...

Anyone else have this ever happen or hear about it? Would rather not do a factory reset - which seems the only option right now unless I'm missing some little setting. The alternative dialer from the play store works great so it's not an issue I have to fix asap. Just bugs me.

Thanks!
