Secure the Note 9
After you turn on your new phone for the first time, there will a few automated series of screens that will guide you through the setup. First, you have to protect your screen, so you choose whether to unlock your phone with a pattern, numeric PIN, facial features, fingerprint, or your iris pattern.
How: the method you pick to protect your phone is going to help with opening the Lock Screen whenever you want to use your phone. Once you pick one, go to Next and you will be required to pick a type (PIN, pattern or password) before you have your fingerprint, face or eyes scanned.
