So far its been so buttery smooth and awesome since updating. Only issue, and a big one to me, is I can no longer connect or even find my home wi-fi. The same wi-fi I used pre-update to download the update! Resetting phone in different ways, resetting router, mucking with router settings, and more to no avail, it cannot find my router despite everything else wireless in the house can. Even tried manually putting the router info in the phone but never says in range. Its able to find all the other many routers in this neighborhood, but not the one I used to download the update. Very saddening. Hope it decides to remember.
