thanks for the help but what's the point of saving this thread if there's only you who responded? Like I said, ALL my messages disappeared along with ALL of my CONTACTS....rebooted multiple times but no joy. Got any real solution besides trying to let me know how smart *** you are?
click on the area it says no messages and give it a few seconds to load. all your messages will re-appear. this could occur due to you having more than 2,000 messages.
tracker-sparql -q "select nie:plainTextContent(?d) where {?d a nmo:SMSMessage}"
Apparently the system is supposed to work well with only 2,000 messages...If you sync your messages using Nokia Suite you can see that if you have more than 2000 messages it advices you to allow it to clean up and store those messages on your PC but delete them from your phone... Its a deficiency of Harmattan from what I see it as...Android too was restricted to 5,000 messages till ICS after which the limit is now 10,000 messages before it starts to lag and causes all sorts of issues...
