Yep, it appears to have fixed the missing Exchange contacts, on mine :)
Battery consumption is worse, though :(
Continuous smartstuff pdates — coder and techie job security program. It ain’t broke, but fix it anyway. Oh oh oh, look, new goodies in the coding toolbox, gotta use ‘em all!
Well, 12 didn’t fix battery consumption, and now copying text and photo handling is awful.
My opinion now is that programmers have run amuck, and lost control of their ever-morphing code beasts.
And I suspect the 11 battery drain problem, which they will not explain, is from greatly increased background monitoring of our actions.
