Device Administration
The Device administrators screen lists all applications that have been given authorization to act

administrators
from the Security screen, and then touch the application name if you want to
remove authorization for
the app to act as a device administrator for the terminal.
Check the Unknown sources box to allow the installation of non-market applications. This setting is
disabled by default.
