Your iPhone can play music and videos, it can provide audio alerts to let you know that you have a new text message or email, and it can ring when someone is trying to call you. But not every sound that comes out of your iPhone can fall into one of these categories, and there are additional noises, like the “Lock Sound” that basically are their own category.
So if you have discovered that the noise that you hear when turning your screen on or off is called the “Lock Sound” then you might be looking for a way to eliminate it. One way is to move the slider on the phone to the “Mute” position, but that isn’t a practical, long-term solution for a lot of iPhone owners. Luckily there is a dedicated setting for the lock sound that you can turn off with the steps in our tutorial below.
How to Stop the Sound That Happens on Your iPhone When You Turn the Screen on or Off
The steps in this article were performed on an iPhone 7 Plus in iOS 10.3.2. The setting that we are turning off controls the “clicking” sound that you hear when you lock or unlock your screen. Locking and unlocking the screen, if you are unfamiliar with the term, refers to turning the screen on or off.
Step 1: Open the Settings app.
Step 2: Select the Sounds & Haptics option.
Step 3: Scroll all the way to the bottom of the menu and tap the button to the right of Lock Sound to turn it off. The lock and unlock sound on your iPhone is turned off when there is no green shading around the button. It is turned off in the picture below.
What Does “Lock Sound” mean on My iPhone 7?
The steps above explain how to disable the lock and unlock sound on the iPhone but, if you weren’t specifically looking to do this, and stumbled upon that setting while trying to change your ringtone, then you might find it confusing.
When you press the Power button on the side of your iPhone 7 to turn off the screen, there is a clicking sound that plays (assuming the device isn’t muted.) That same sound will also play when you press the Power button to turn the screen back on. That sound is the “Lock Sound” and provides an audio cue that the lock state of your iPhone has changed. It’s also a very distinctive sound and, after a few days of hearing it constantly throughout the day, you may discover that you would prefer to turn it off.
