- there are more toggles in notification panel, the data connection one is what I like most;
- you can also adjust brightness in notification area;
- the graphical effects looks better;
- you can see the notification panel from the screenlock (well, maybe not everybody likes this one);
- you can alphabetically sort apps in grid view.
What I do not like:
- I can no longer adjust brightness by holding the notification panel and moving left and right;
- I can no longer disable some bloatware using native apps manager;
- the battery time is still bad compared to my old Samsung i8910 :-(
- When setting wallpapers Jelly Bean only use the center part of the .png/.jpg image. If your wallpaper is larger in the vertical axe (like mine) Jelly Bean will crop the upper and lower parts :-/
Yesterday I had one problem with phone rebooting after I had left it turned off charging all night. It worked for one minute, then freezed and rebooted a couple of minutes later. It did not tree times until I hooked up the USB cable to try to run logcat and see what was happening. By my suprise it stopped reboot and I could use the phone normally. I looked in the logcat I saw that Youtube app was crashing with the message
E/AndroidRuntime( 7635): java.lang.RuntimeException: Unable to create application com.google.android.youtube.app.YouTubeApplication: java.lang.RuntimeException: Could not bind to Intent { cmp=com.google.android.youtube/.core.transfer.DownloadService }
The Youtube app was already showing a dialog before I turned the phone off, I tried to make it work with no avail. I also searched on the Internet if anybody had the some problem and have not found any explanation for that. After some minutes tring to make Youtube work I gave up and went to do something else. Some minutes later I tried Youtube again and guess what? It worked :-) and is still working. I really do not know what happened.
