Xperia S ringing randomly

[nei1337]

it's happened twice now since the ICS update. The phone just starts playing the ringtone, no incoming call, no notification, nothing happening. Turn the volume down and back up, its still there. Only thing that seems to stop the ringing is turning the phone off.

Anyone else had this issue?

Any way of solving it?
