This has been randomly happening all day, and its been driving me nuts. The phone will just start going "beep beep" while im on a call, and i mean like every few (maybe 10?) seconds or so. Rebooting the phone seems to fix it temporarily, but then it comes back again later...I uninstalled all the apps i had installed prior to this happening (including tasker, which i reeeeeally hope isnt the problem as i love it)....but does anyone know what it could be???
