Does this need a clarification, like "from external apps"?

[SeRya, 2014/09/15 15:20:00]

Theoretically this label may be shown when user installs an external
application. It will be among requested permissions (not sure it's the case for
signature protected permissions). So text like "Debug web pages in Chrome Shell"
would be more appropriate. In reality it's hardly someone needs to publish an
application with what permission. When you install an app through ADB the
message is not shown.
