Google Smart Lock is a feature that allows you to lock your Android device using your Google account. This feature is available on many devices, but it may be useful for you if you have an Android device that uses a different type of security code than your standard one. To use Google Smart Lock on your Android device, first make sure that you have the Google Smart Lock app installed. Once the app is installed, open it and sign in to your Google account. Then, open the Settings app and select Security and Privacy. Under Security and Privacy, select Google Smart Lock. Now, enter the code that you used to unlock your device in the text field and click on the lock button. If everything goes well, you will see a message saying that Google Smart Lock has been activated on your device. If not, please check back later because there may be some issues with this feature.
