Select device administrators
The Device Administration feature allows you to select one or
more administration applications that control your device for
security purposes (for example, if your phone is lost of stolen).
These applications enforce remote or local device security
policies.
Some of the features a device administration application might
control are:
•
Setting the number of failed password attempts before the device is
restored to factory settings.
•
Automatically locking the device.
•
Restoring factory settings on the device.
Note:
If a device uses multiple enabled administration applications, the
strictest policy is enforced.
