Every time you take the Samsung Galaxy S9 out of standby, you must unlock the lock screen to access various functions of the device. When unlocked, you will hear a sound indicating that the screen is unlocked.
This noise may be annoying in the long run, so you want to disable it. We show how this works in Android: Deactivate screen lock tones on the Samsung Galaxy S9
