Galaxy Note GT-N7000 firmware update Aug 2012

I received an update this morning (though Kies) for the Galaxy Note:
PDA:LR6 / PHONE:LR1 / CSC:LR2 (INU)

Updt 22 Aug: This version of firmware has remarkably improved the battery life of the Note. I went 5 days without plugging in, and the battery went from 100% to 35%. The following parameters should be considered:

  • I don't have a Task Killer
  • wifi, data traffic, bluetooth and GPS are switched off most of the time
  • I did not turn on power-saver mode
  • total voice-calls were less than 20 minutes
  • very light overall usage (that means screen was mostly off)
Nevertheless, this improvement is astounding.
Pressing *#1234# on the keypad gives me:

Java Applet Security Issue - java.io.FilePermission


A while ago I ran into this issue where an applet was used to upload files.

Security manager class: sun.plugin2.applet.AWTAppletSecurityManager
Exception in thread "Thread-45" java.security.AccessControlException: access denied (java.io.FilePermission ...) 

The solution is to create a .java.policy file and explicitly give the applet permissions to access your file system.
Path in Windows Vista: C:\Users\<username>\.java.policy


grant {
  permission java.security.AllPermission;
  permission java.io.FilePermission "file://C:/Users/username/Documents/special/*", "read, write";
};

Here, you will need to replace the path to something of your choice.
