I am experiencing a weird problem. On startu,p while the notification bar is displaying "preparing sd card" and "preparing phone storage" a strange tone is played. It sounds like a ringtone preview...but it doesn't sound pleasant. It makes you believe that there is an error somewhere, but there is no verbal notification. I recently updated several apps at once and installed a new one. I thought this may be the problem, but I still have the sound after uninstalling new app. Anyone experience anything like this?
