At first I thought this was user error. But when my call log started to be inconsistant, I figured out it has to be something else.  Out of nowhere, my messages has started deleting themselves whether I read them or not, and my call log is in random or deleting all together as well.  I have checked my order options & filters – nothing.   I also deleted some messages & call log in case it were a memory issue even though there is plenty of main memory left.  I have of course also tried a hard reboot… I'm out of ideas… got any?
