So I got a droid x and it has been fine except sometimes it will randomly lockup in the music app. I haven't seen it look up anywhere else. The screen is not responsive and the music stops playing, but the counter starts at 0 and goes to 9 and starts over like it is playing a song. The physical buttons work and I just hit the home button and that usually unfreezes the app. But I'm not sure why it would do that. Should I get it exchanged?
