Think i found a way to disable the annoying pop-up that asks you multiple times a day if you want to update to Android 4.3. I'm really hesitant to upgrade because I previously owned a Samsung that was ruined by an update - and i know a lot of people are experiencing problems on their SG3 after switching over to 4.3. All you do is drag down the status bar on the home screen when the notification appears. Touch and hold until an App info window appears. Open that up and it brings you to the process responsible. Finally hit Clear data. I have gone several hours without seeing the 4.3 notification appear again. I also rebooted the phone to test. Hopefully this will be a permanent fix. If not..oh well.
