Why alarms sometimes not works, when phone is switched off?
The Best of all - In Czech version of Guide is assurance, that Alarm Clock is activated when Phone is switched on!
- If you don't use key On/Off/End after switching Phone off, all active alarms will be work normally.
- If you press shortly key On/Off/End after switching Phone off, all alarms will be temporally deactivated.
