Yeah, it would be interesting to hear other's opinions. I'm still jaded and love 4.1.2 more than 4.3. Though I'm starting to live with it. I just hate it when I need to resort to other apps to get some 4.1.2 functionality back. I'm living with it (doesn't translate to liking it)... But it gets the job done. I might try Widget Locker for the lock screen; if only to get rid of the butt ugly interface that is in its place now. Also see if I can customize it to the way I want it. But from what I see, I would say an average user that doesn't use much of the features already really won't notice a difference. I think users who use a lot of the features from 4.1.2 will notice how much is lost and how little was added to the update. It's us heavy users that gripe and complain because it feels gutted more than anything else. Light, moderate or heavy user? Keep us posted... Only way to tell if the update was 4.3 is to check About device in the settings. If it still says 4.1.2, then it wasn't the 4.3 update. Have you tried doing a cache wipe in the Android Recovery Console? Then check manually for the update? Light, moderate or heavy use? I know battery life is stellar under light use. But when I push it and go moderate to heavy use, the battery tanks. I had Puffin force close. Sent the report out after that. Still there. They kept it the same with the 4.3 update for the Note 2. I'll check it out later and see how Puffin handles it. I don't use Instagram, so not sure. But internet pages that have pics don't pixelate on mine. I'll view my photobucket account and see what that looks like. I'll check both mobile and desktop modes. Try booting into safe mode first and see how battery life is. Maybe a 3rd party app is screwing it up. Or something residual or old could be messing with it which might require a hard wipe to fix. I forgot who it was stated that doing a hard wipe and SD format fixed the issue. It's somewhere in this thread. Battery life should be stellar if left in standby. I find it's really bad if put into moderate to heavy use. WTF? I wonder what AT&T removed from the update... Mine was 705.39MB.
