Personalizing a smartphone is not just changing the wallpaper, but also customizing the sound that we hear hundreds of times a day. The screen lock sound on Android is that short signal that notifies you that you accidentally pressed the power button or the device detected the closing of the case cover. For many users, this sound becomes intrusive, too loud or simply annoying, especially if it is repeated many times.
Unfortunately, modern versions of the Android mobile operating system are gradually abandoning the ability to completely replace this particular audio file without obtaining root access. Security Policy Google and device manufacturers strive to minimize interference with system files to avoid crashes. However, depending on the model of your gadget and the firmware version, there are still ways to change or completely disable this sound.
In this article we will analyze in detail all the available methods: from standard settings in shells of different brands to more complex manipulations with the file system. You will learn how to turn off the lock sound on Samsung, Xiaomi or pure Android, and you will also understand why this option has disappeared completely on some new smartphones. We will look at both software solutions and the physical features of the operation of proximity sensors.
Standard sound settings in various Android shells
The first thing you need to do before looking for complex solutions is to carefully check the standard settings menu. The Android interface varies greatly depending on the manufacturer, and what is hidden in one model may be available in another. For example, in smartphones Samsung with the One UI shell, sound management is placed in a separate, very detailed section.
Usually the path looks like this: go to Settings → Sounds and vibration → Lock screen sound. Here you can see a switch that allows you to completely deactivate the signal. If there is no switch, but there is a selection of melodies, you can replace the standard system sound with silence or a neutral signal by selecting the appropriate file from the list.
In devices Xiaomi (MIUI and HyperOS) the situation is a little different. Often the locking sound is tied to the design theme. If you are using a third-party theme from the Mi Themes Store, it may force its sounds to turn on, ignoring system settings. In this case, returning to the standard theme often solves the problem with unwanted audio.
⚠️ Attention: In some versions of Android 13 and 14, manufacturers have completely removed the “Lock screen sound” menu item. If you do not find this section, this is not a fault of your smartphone, but an intentional limitation on the part of the firmware developer.
It is also worth paying attention to the section Accessibility. Sometimes audio settings are duplicated there or controlled by profiles that are enabled for a specific usage scenario. Check to see if you have Do Not Disturb enabled, which can mute some sounds but allow other system notifications to pass through.
How to turn off the lock sound on Samsung Galaxy
Smartphones of the South Korean giant have one of the most flexible sound settings systems among all Android devices. If your goal is silence when pressing the lock button, the action algorithm for owners Samsung will be the simplest and most understandable. The system allows you to control this parameter regardless of the volume of the media or call.
To begin, go to the main settings menu and select Sounds and vibration. Scroll down to the very bottom of the list. There you will find the option Lock screen sound. By clicking on it, you will be taken to a submenu where you can not only select a different melody, but also see a switch at the top of the screen. Move it to the inactive position, and the sound will disappear.
It is important to note that on some models of the series Galaxy A or older versions of One UI, this item may simply be called “Lock sound” and be located in the section "Additional sounds." If you updated your phone recently, the interface may have changed, so you should use the search in the settings by entering the phrase “lock.”
Use the search in the settings (magnifying glass icon at the top of the screen) by entering “Lock sound”. This is the fastest way to find the desired switch, even if the manufacturer has changed the menu structure.
Another nuance concerns the function Direct Call or smart lock. If your phone unlocks automatically when you hold it to your ear, you may not hear a locking sound because the system thinks you're already interacting with the device. However, when you manually press the button, the sound will work according to your settings.
Features of changing the sound on Xiaomi and Redmi
In the ecosystem Xiaomi audio file management is closely related to the theme store. This creates certain difficulties for users who simply want to set silence. Often, the standard lock sound is “hardwired” into the active theme, and system settings do not allow you to change it while the theme is active.
To bypass this limitation, follow these steps:
- 🎨 Log in to the application
Themesand go to the user profile. - 🔄 Select a theme Classic or Default (standard MIUI theme) and apply it.
- 🔊 Now go to
Settings → Sound and vibration → Advanced. - 🔇 Find the “Lock sound” item and try changing it or disabling it.
If even after changing the theme the option remains inactive, you can try the trick of replacing the file. To do this, you need to download the silence audio file (silence.mp3) and rename it exactly like the system lock sound file, then replace it through the file manager with root access. However, this method is too risky for ordinary users.
In new versions HyperOS the company began to implement more stringent restrictions. Users note that the locking sound is now often synchronized with the charging sound or other system events. In this case, muting one sound may result in muting other important notifications, so be careful when experimenting with the volume sliders.
Why can’t you select “Mute” on Xiaomi?
MIUI developers believe that tactile or sound feedback when locking is required to confirm the user's action. The absence of sound may result in the user not realizing whether the screen is locked and pressing the button repeatedly.
| Smartphone brand | Path to settings | Disable option | Features |
|---|---|---|---|
| Samsung | Settings → Sounds → Lock sound | Full | Separate switch |
| Xiaomi / Redmi | Settings → Sound → Advanced | Partial | Depends on the theme |
| Google Pixel | Settings → Sound and vibration | Absent | Only in older versions of Android |
| Honor / Huawei | Settings → Sound and vibration | Full | There is a choice of melodies |
Solving the problem for pure Android and Google Pixel
Owners of smartphones with “pure” Android, such as Google Pixel, Motorola or Nokia, face the greatest difficulties. Since Android 10, Google has consistently removed the ability to customize the lock sound from the user interface. The logic of the developers is simple: the lock screen is a system security event, and it must have a unique, recognizable sound that cannot be changed by a third-party application.
In the menu Settings → Sound and vibration → Advanced settings you most likely will not find the “Lock screen sound” item. This is normal system behavior. Attempts to find hidden menus through engineering codes (for example, ##4636##) in modern firmware versions also do not yield results, since access to these functions is closed at the kernel level.
However, there is an indirect way to reduce the volume this sound. It consists in managing the general level system sounds. In the sound settings, find the “System sounds” or “Interface sounds” slider. If you reduce it to minimum, the locking sound will become almost inaudible, although it will not disappear completely.
⚠️ Note: Reducing the volume of system sounds will also affect the dialing sound, keypress sound, and other system responses. Take this into account if these functions are important to you.
For advanced users who are willing to risk system stability, there is a method for replacing the system file Lock.ogg via a computer and ADB (Android Debug Bridge). This process requires USB debugging to be enabled and root access. Without root access, replace the file in the partition /system/media/audio/ui/ It will not work because writing to the system partition is blocked.
Using third-party applications and launchers
If standard methods do not work, applications from the Google Play Store come to the rescue. There are special utilities, such as Button Mapper or various sound managers that can intercept the event of pressing the lock button. However, there is an important technical nuance here: most of these applications can reassign the action of a button (for example, a double press), but cannot replace the system sound itself, played by the OS when pressed once.
A more effective solution may be to install a custom launcher, although they mainly affect the desktop, not the lock screen. Some launchers have their own lock screens with custom sounds. By activating such a screen, you replace the standard system lock screen with a software one, where the sound can be turned off in the settings of the application itself.
Popular applications for customization:
- 🔒 Hi Locker: Allows you to create your own lock screen with any sounds.
- 🎵 Sound Assistant (from Samsung): Allows you to fine-tune the volume for each application and system event separately.
- ⚙️ MacroDroid: A powerful automation application that can create macros for the “Screen off” event and play (or not play) sound.
☑️ Check before installing applications
Using macros in MacroDroid is the most flexible option. You can create a script: "If screen turns off → Wait 0 seconds → Play Silence sound (or do nothing)." This allows you to programmatically override the standard behavior of the system without interfering with system files.
Hardware reasons and proximity sensors
Sometimes the problem with a constant locking sound lies not in the settings, but in the hardware. The proximity sensor, located next to the earpiece, is responsible for turning off the screen during a call or in your pocket. If this sensor is dirty, covered with a low-quality protective glass, or is faulty, the phone may think that it is constantly in the dark or locked.
As a result, the device may randomly lock and unlock in your pocket, making characteristic sounds every time. In such a situation, no software sound adjustment will help, since the problem lies in false alarms of the locking mechanism itself.
For diagnostics, wipe the top of the screen with an alcohol wipe. Remove the protective glass if it covers the sensor area. You can also use the engineering menu to check the operation of the sensors. Enter the code #0# (works on many Samsung and other models) and select test Sensor. Look at the proximity sensor readings: cover the top of the screen with your hand, the value should change from 0 to 5 (or vice versa).
If the proximity sensor does not work correctly, the phone will constantly make locking sounds in your pocket, which will quickly drain the battery. In this case, cleaning or repair is needed, not sound adjustment.
⚠️ Attention: Do not cover the top speaker area with thick stickers or thick covers. This disrupts the operation of the light and proximity sensor, which leads to a malfunction of the lock screen.
FAQ: Frequently asked questions
Why did the lock sound setting disappear after the Android update?
Google and smartphone manufacturers are striving to unify the interface and improve security. The lock sound is considered a critical system event that confirms user action. In new versions of Android (12, 13, 14), this option is often hidden or removed completely to prevent accidentally turning off important feedback.
Is it possible to set your music to the lock sound without root access?
On most modern smartphones without root access, this cannot be done through the standard settings. You can only select one of the preset ringtones. The exception is some shells, like the old version of MIUI or One UI, where you upload your files to the notification folder, but this rarely works for the lock screen sound.
Does Do Not Disturb mode affect the lock sound?
Usually no. Do Not Disturb silences calls, messages, and app notifications. System interface sounds, such as keyboard clicks, camera focusing sounds, and screen lock sounds, often ignore this mode and continue to play because they are classified as system sounds and not notifications.
How to mute the sound when you put the phone face down?
This feature is called “Mute when flipping” or “Mute gesture”. It is located in section Settings → Accessibility → Gestures and movements (path may vary). Turn off the switch associated with turning the device over so that the phone does not make sounds when changing position.
Is it safe to replace system files through Root?
Replacing system files (for example, Lock.ogg to an empty file) requires root access and unlocking the bootloader. This will void the device's warranty and may result in the phone becoming bricked if an error occurs. In addition, banking and Google Pay applications may stop working due to a violation of the integrity of the security system.
