Hello, A few months ago, my Xperia P just randomly started playing one of the standard alarm / ringtones of its own accord, and I couldn't turn it off. The funny thing is, it wasn't either of the tones I have selected for ringtone, alarm, or incoming text / tweet etc, it was one of the generic ones. I went to the sound settings and the clock and there was nowhere I could obviously turn it off. I turned the phone off, but when I turned it back on, the tone piped up again and I still couldn't silence it. In the end the only thing I could do was turn the volume down completely. When I turned it up 15 minutes later it was still going. Eventually after about half an hour I turned it up and the tone had stopped. Has anyone else experienced this and is there a solution? I might try deleting the tone in question, as it has been the same tone each time. Thanks Stu
