Hi, I have a nexus one running 2.3.4. Yesterday, for some unknown reason, every couple of hours, it just starts playing some weird music for about 30 seconds. I've tried powering off and on again - but it still does it. I have no alarms set and I've looked for some obvious applications, but nothing makes sense. I've even tried running an AVG scan on the machine. It has to be some application thats doing it - but I don't know what. Has anyone else seen this - or does anyone have any ideas? Is there a log on the machine that holds automatic updates? Regards, Ian.
