Following the steps of iOS 11, Android 9.0 Pie includes a security feature that lets you instantly disable the fingerprint scanner and advanced Smart Lock features. After initiating the feature, you will need to enter your PIN, pattern, or password before other unlock methods will work again.
This is a nice addition to Android since law enforcement, street robbers and other would-be assailants can force you or make you unlock your smartphone with your fingerprint, face or voice. Or someone with a similar face or voice can unlock your phone without your biometric signature. However, when it comes to law enforcement, due to the 5th amendment rights, they can not legally enter a pattern, PIN or password.
Apple's version requires you to either press two buttons together for a few seconds to enable lockdown mode (on newer iPhones), or click on a button five times in a row (on older iPhones). Google's version is also very easy to trigger, but it is not automatically default in Android Pie as Apple is enabled in iOS 1
To get this new security feature in Android 9.0 on your Pixel, Pixel XL, Pixel 2 or Pixel 2 XL (the process is similar for partner devices running Android Pie), just go to "Security & Location" in Your settings and tap "Lock Screen Settings" under Device Security . Next, make sure you enable the "Show lockdown option" option and you're done. If you do not see this option, it's probably because you've chosen a wipe screen lock instead of a pattern, PIN, or password.
To actually use the lock mode, simply press and hold the power button. The power menu appears. This can be done from the home screen, the lock screen, or any app. Then tap the "Enter lockdown" button or just "Lockdown" in the Power menu, depending on which Android Pie version you are running. The next time you try to unlock your phone, you will need to enter your pattern, PIN, or password first.
Once you've entered your pattern, PIN or passcode You can still use your fingerprint or Smart Lock options such as "Trusted Face" or "Voice Match." If you have enabled Smart Lock features, you can simply tap the unlocked icon on the lock screen to disable it, but You can still unlock the phone with a fingerprint. This new lockdown mode disables all unlock methods except Pattern, PIN, and Passwords, ensuring that your data is safer than ever before.
Because it integrates directly with Android 9.0 Pie, other smartphones will someday receive this feature as Samsung and HTC could follow their own versions of lockdown mode before Android Pie even hits other devices.
