I've been facing the issue of missing alarms for a week. I can set alarms successfully, it displays in notification but not running.

Though if I try to check it will have work or not by setting alarms after 1-2 minutes, then it works ok. But if I set alarm before sleeping then it doesn't ring on morning.

One another thing may be related: I'm getting "Unfortunately clock has stopped" alert randomly about 2-3 times in a day (though it is not happening exactly while setting alarms).

So, I'm not getting what's going wrong with alarms. How can I recognize the issue and fix it?

Note: Running (non-rooted as running under time period of warranty) Android 6.0 on Lenovo .

  • Not sure, but could it be you've "dozed" the alarms app (or something related)? Btw: Never heard there's an Android 6.20. Must be something Lenovo specific :)

  • @Izzy I've disabled only calculator (also "force stop" would not be case as I've tried reboting several times). Btw was typo.

    Could you be specific about your device model? Are you using only the stock Clock app? Have you tried clearing the data for that app? Jan 9, 2017 at 13:56
  • @MatthewRead Lenovo A6600 Plus. Yes, using only stock Clock app. Ok I've cleared data now let me check for next alarm.

  • @MatthewRead Clearing data worked. Now alarms are working fine and "unfortunately clock has stopped" message has gone permanently!
