Sony Ericsson Xperia X10 Mini/pro :: Alarm Snooze Function And Calendar

My alarm clock sometimes decides to snooze for an hour and 10 mins rather than 10 mins. I nearly missed work on Friday, what is going on!? I waited a long time for the X10 mini to come out and admit that I am a little dissappointed. I've had a SE W580i until recently and I am finding that there are a lot of basic things that my old phone could handle but my new one seems to struggle with.I have used my phone alarm as my only alarm clock for at least the last 5 years. I really struggle to get up in the morning and if I turn the alarm off, I'll fall straight back to sleep again, therefore I rely heavily on the phone's snooze function to wake me up eventually after going off a few times. I was initially dissappointed that you cannot personalise the snooze duration on the x10 mini, the 10 mins is usually ok for me but in certain situations I prefer to shorten it. Please consider including this in the next software update, Sony Ericsson!

But the pressing problem is the (massively) extended snooze. It happens every few days and seems to be quite random. The first few times I hit the snooze button, it works as normal. A picture of an alarm clock comes up showing the time, and a white segment of clock face is highlighted indicating how long the snooze is for (10 mins) and when it will next go off. Then, I stir due to some disturbance outside, notice that the sun is definitely brighter than it was when I was last awake, grab my phone in a panic and realise that I have been sleeping for 20 mins since the alarm last went off, and that I have less than 7 mins to get up, dressed, packed and on the bus or I will be late for work. Meanwhile my phone is cheerfully still displaying the clock face with the white segment showing that I have 40 mins left to snooze and all is well. I didn't even know it was possible for this phone to snooze for anything other than 10 mins. Unfortunately I am asleep whenever this has happened and I'm not sure how I've done it.

I have tried setting the alarm when awake and then pressing various buttons, tapping the screen in various places, even pressing and holding the snooze button or swiping it. Most of these actions do nothing and the only way to stop the alarm is to slide to turn off or press the snooze button. My theory as to what is happening is that the phone snoozes for the normal 10 mins, but then when it reaches the time to go off again, it fails to go off and then the snooze time is displayed as 50 minutes (until it reaches that time again for the next hour). I think the white segment does initially show the 10 mins, I've started checking when I hit the snooze button after it happened a few times, but I might be doing something different in my sleep somehow.
