Locking the Screen

Your phone automatically uses a default Lock Screen to simply prevent unintentional function activation. You can choose to secure your phone so that only you can unlock it to make calls, access your data, buy applications, and so on. For added security to guard against unauthorized use, you can set a requirement (such as face unlock, pattern, PIN, or password) that will need to be entered to unlock it. You can also set no lock screen at all.
