My new A40 transferred calendar entries from my old A3 no problem. A few days later it has decided to delete the majority of entries but not all. Very odd. I've never synced, I just use the calendar on my phone. I have all calendars ticked in case they are hiding but no luck. Are they gone forever or is there a wayto retrieve? I hadn't backed up on this phone as I've never had issues with calendar before. Can anyone help?
