Android 4.1 add the following new permissions:
- READ_EXTERNAL_STORAGE
Provides protected read access to external storage. In Android 4.1 by default all applications still have read access. This will be changed in a future release to require that applications explicitly request read access using this permission. If your application already requests write access, it will automatically get read access as well. There is a new developer option to turn on read access restriction, for developers to test their applications against how Android will behave in the future. - READ_USER_DICTIONARY
Allows an application to read the user dictionary. This should only be required by an IME, or a dictionary editor like the Settings app. - READ_CALL_LOG
Allows an application to read the system's call log that contains information about incoming and outgoing calls. - WRITE_CALL_LOG
Allows an application to modify the system's call log stored on your phone - WRITE_USER_DICTIONARY
Allows an application to write to the user's word dictionary.
