I do have a few things to report.
I upgraded from Android 4.2.2 to 4.3 earlier today. After being bummed out that there's still no Photosphere on stock firmware I discovered something far worse..
It lags. I don't mean "Eh, it lags a little here and there", no. I mean, it lags so bad that I can barely use the tablet sometimes. Even just swiping to a new page on the home screen takes over two seconds most of the time.
The tablet always feels warm too, as if the CPU is running under load. Even while asleep it stays warm, and when I'm playing a game it gets so hot that it's actually mildly painful.
Just to be sure I'm not crazy I went and grabbed CPU-Z. Yep, all four cores are on and the load's almost always at 75% or over, only dropping down to 0% for a half second about once a minute. Often it'll jump to 100% and stay there for extended periods of time as well.
The only thing I know I'm running, for sure, is CPU-Z. Nothing else is listed in the app switcher or in the upper left corner. The services look normal (just stock stuff running plus a live wallpaper ("Day Scene") and Swiftkey apart from the usual Google and Asus stuff).
Under "battery", "Media" is using 57% of the system's power. I don't know why this is running. Honestly, I don't have the slightest clue. From a fresh boot the thing's lagging right off the bat, no music playing, no videos, and yet this thing's right up there. After downloading a task manager I found that "android.process.media" and "Google+" are each using about 50% at all times.
I'm running stock firmware, it's not rooted, it's not unlocked; everything's off the shelf.
Am I the only one experiencing this issue or have any suggestions on how to fix it, and how to get Photosphere on this tablet?
