Why enable lockscreen on Android?
For a start, everyone has his/her personal text messages, photos and videos in the Android phone. And they are not willing to be peeked. However, it is easy to slide to unlock an Android phone and reach all data in the device. If someone picked up your lost phone, it will be probable for them to invade your privacy. Besides, without lockscreen, your Android phone is more likely to be deleted by your children when they flirt with your phone as he or she can easily unlock your device. And it will be difficult to recover your deleted Android data. To prevent situations mentioned above, you can enable lockscreen on Android.
Step 1. Choose Screen Lock
Turn on your Android phone. Then go to "Settings" > "Security". Then you can choose screen lock mode – Pattern, PIN, or Password.
Step 2. Enable Lockscreen on Android
Pattern: Draw a pattern on the screen > Click "CONTINUE" > Re-draw the pattern > Choose "CONFIRM".
PIN: Enter PIN code (4 digit or above) > Hit "CONTINUE" > Re-enter your PIN code > Tap "OK".
Passcode: Enter your password which must contain at least one letter. Then click "CONTINUE". Re-type your passcode and hit the button "OK".
Step 3. Choose a Way to Show Notification
Last, decide the way in which notification shows when your phone is locked, for example, show all notification content, hide sensitive notification content, and don't show notification at all.
Write in the end:
After enabling lockscreen on the device, you can turn on "automatically lock after sleep" setting or "power button instantly lock" setting. Also, you can enable or disable the pattern/password visible setting.
