Alarm sounds every 10 minutes

[anglaslt]

I'm new to the Xperia U and this support forum. I have a problem I cannot solve. Every 10 minutes an alarm sounds and I cannot turn it off. I assumed it was the snooze alarm although I've never set or used the alarm. I went through all the settings I could think of, made sure the alarm is off, turned off the alarm volume but still it sounds.

Any advice will be most welcome.

are you certain its not a calendar reminder?

Thanks uliwooly, I was hoping that's the answer even though I hadn't knowingly set any events. I tried cancelling events (there were none) and cancelling event notifications but it still sounds exactly every 10 minutes.

Any other suggestions anyone?

Thanks again but still no luck.

Well, I'm pretty sure a factory reset will work.  One question: What's your current Android Version and Build Number?

Thank you. I did a settings reset with no effect. Looks like I'll have to try a factory reset as you suggest. It's v4.04 IMEI 352266053534658
