When enabled, password characters display briefly as you
touch them while entering passwords.  

1.  From a Home screen, touch 

Apps ➔ 

➔ Security. 

2.   Touch Make passwords visible to create a check 

mark and enable or disable the display of password 

characters. 

The Device Administration feature allows you to select one or 
more administration applications that control your device for 
security purposes (for example, if your device 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 a Home screen, touch 

Apps ➔ 

➔ Security. 

2.   Touch Device administrators, to select a device 

administrator, and follow the prompts. 

If no device administrators are listed, you can

download them from the Play Store.  

3.   Touch Unknown sources to download and install 

non-Market applications. 

Warning! Enabling this option causes your device and 

personal data to be more vulnerable to attack by 
applications from unknown sources. 

4.   Touch Verify Apps to cause your device to either block 

or warn you before installing apps that may cause 

harm to your device. 

5.   Touch Change security level to set the security level 

to High or Normal.
