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.
1. From the Home screen, tap ➔ Settings ➔ Security
and lock screen.
2. Tap Device administrators.
3. Select a device administrator and follow the prompts. If
no device administrators are listed, you can download
them from the Play Store.
Unknown sources
This feature allows you to download and install non-Market
applications.
1. From the Home screen, tap ➔ Settings ➔ Security

from unknown sources.

for some other reason you do not trust it, you can disable or
remove it.
1. From the Home screen, tap ➔ Settings ➔ Security
and lock screen.
