Protecting your phone with a screen unlock pattern
You can protect your phone by creating a screen lock. When enabled, you
need to press and hold certain icon, draw a pattern or enter a numeric PIN or
password to unlock the phone’s screen and keys.
1. From the home screen, tap > System settings > Security.
2. Tap Screen lock.
3. Tap Long press, Pattern, PIN, or Password.
• Tap Long press to enable screen lock and allow unlock with a “press and
hold” gesture. You can unlock the screen by tapping and holding on the
display.
• Tap Pattern to create a pattern you must draw to unlock the screen
• Tap PIN or Password to set a numeric PIN or a password that you must enter
to unlock your screen.
Important: If you forget the pattern you set, try ve times and tap Forgot
Pattern? to sign in to the Google Account you have added on the phone
and reset the screen lock. You need an active Internet connection. You can
also upgrade the phone software. (see Upgrading the Phone Software).
Protecting your phone with encryption
You can encrypt all the data on your phone: Google Accounts, application
data, music and other media, downloaded information, and so on. If you
do, you must enter a numeric PIN or password each time you power on your
phone.
Warning! Encryption is irreversible. The only way to revert to an unencrypted
phone is to perform a factory data reset, which erases all your data.
Encryption provides additional protection in case your phone is stolen, and
may be required or recommended in some organizations. Consult your
system administrator before turning it on. In many cases the PIN or password
you set for encryption is controlled by the system administrator.
Before turning on encryption, prepare as follows:
• Set a lock screen PIN or password.
• Charge the battery.
• Keep the phone connected to the charger.
• Schedule an hour or more for the encryption process: you must not
interrupt it or you will lose some or all of your data.
When you’re ready to turn on encryption:
1. From the home screen, tap > System settings > Security > Encrypt
phone.
2. Read the information about encryption carefully.
The Encrypt phone button is dimmed if your battery’s not charged or your
phone’s not plugged in.
If you change your mind about encrypting your phone, tap .
Warning! If you interrupt the encryption process, you will lose data.
3. Tap Encrypt phone.
4. Enter your lock screen PIN or password and tap Next.
5. Tap Encrypt phone again.
The encryption process starts and displays its progress. Encryption can take
an hour or more, during which time your phone may restart several times.
When encryption is completed, you’re prompted to enter your PIN or
password.
Subsequently, you must enter your PIN or password each time you power on
your phone, to decrypt it.
