If you’ve forgotten the password for your Samsung Galaxy S9, you can easily reset it following these simple steps:

• Start by pressing and holding the “Home” button, together with the “Volume Up” button.
• When the logo of the phone appears, release both keys and press the “Power” button.
• You’ll be taken to the Android System Recovery page. Navigate to “Wipe data/factory reset” using the volume keys.
• Select the option with the “Power” or “Home” button.
• You’ll see a “confirm wipe of all user data” screen. Select “Yes” and then restart your device.

Now that you’ve reset the phone, you will be asked to set a unlock pattern for your Galaxy S9. You can either choose a pattern, a PIN or a password and your phone will be locked and secure all over again! 라고 구글신꼐서 알려주시네요!
