Starting last week, call logging is not working anymore on my Z10 ... I don't know what's happened. I tried to flush the call history and it is actually flushed, but no more records are registered anymore. This concerns "All calls" and "missed calls".
Thanks for your reply, I just flushed the call history again and it seems to be back in service ... let's finger cross.
But for now, I can confirm that my issue has been fixed !
