So far so good with 4.2.2 and Sense 5. Phone seems stable so far, and I like the new look. Pros: -Stock calendar is updated and improved -Quick access to settings with two-finger pull-down is nice -The new app tray options are pretty cool. You can easily sort by alphabetical or most recent, and you can get into the Play Store directly from there. You can also easily hide apps from the tray. Pretty slick. -Lock screen shortcuts are easier to deal with. You just pull them straight up, not into the circle. Not a huge improvement, but better nonetheless. Cons: -Home screens no longer rotate all the way around. Once you get to the end, you need to go the other direction. So if you have 5 screens, and 3 is your main screen, if you go to the right to 5, you have to go back all the way to the left to get back to 1. Much easier when you could just keep going around and around. -I was hoping for more improvement to the stock email client. I'll continue using Cloud Magic -Stock keyboard still sucks, thankfully SwiftKey doesn't. -Some of the notification sounds have been eliminated, so I had to choose new ones. Annoying.... Intheory there's also a long list of other bug fixes, including better wifi, bluetooth and navigation performance. We'll see if those make any difference. I'll update as I use it more, but so far it is a worthy, solid update.
