Samsung Galaxy Tab 2 10.1 用户手册

This menu contains features that allow you to configure the device’s security parameters. 

Data encryption allows you to encrypt all data that is on your device to enhance security after 

you turn it off. 

Important!  

Password screen lock protection represents the highest level of security; 

therefore, you must setup a screen lock password in order to use device 

decryption. For more information, see 

1.   Press 

and tap 

> 

> Security > Encrypt device. 

2.  At the Encrypt device prompt, tap OK. Your device restarts. 

3.   Unlock the device. The data on your device is encrypted and your device restarts again. 

The icon displays on the top bar of your display showing that your data is encrypted. 

Prevent another user from accessing information stored on your SD card by protecting the 

information using a password. When enabled, your device will ask for a password each time you 

use the device. Using this option you can also change your SD card PIN number.

encryption. For more information, see

2.  Tap Encrypt external SD card. 

3.   Follow the prompts to encrypt your SD card. You may be required to set a lock screen 

password first. 

When enabled, this feature allows you to view the text being entered into a password field as 

you type it. Many times, other applications insert an asterisk (*) as you type. This can cause 

issues and confusion. What if you mis-typed the password or used the wrong case? When 

enabled, you can see your entry. This feature is enabled by default.
