I have only just discovered that if the alarm clock on my mobile phone is 'on', it still rings, even if the phone is turned off.
The circumstances surrounding my discovery are rather sad - my dear dad died three weeks ago, so I was staying with my mum. Dad's phone alarm rang at 8am every day for several days (and must have done so at least a couple of times in the hospital) before I realized that switching the phone off wasn't going to stop it happening again. Today, I have finally tested this out on my own, much more modern phone, with the same result - if I don't turn the alarm setting to 'off', it will ring even if the phone is turned off!
I'm smiling about this now, but really wishing I could ask my dad if he knew or not, as his thirst for knowledge never diminished so i know he would have been either interested or amused!
Am I the only person not to have known this before (though I rarely switch my phone off, so wouldn't have found out by chance)?
