Smartphone owners Samsung often face a situation when the device suddenly stops making sounds during calls or notifications. This condition is puzzling, especially if the user has not manually activated silent mode. Most often, the reason for this behavior is the activated function Do Not Disturb, which blocks all incoming signals to ensure silence.
This function is useful during sleep or important meetings, but its accidental activation can lead to missing critical calls. In this article, we will look in detail at how to find and deactivate this mode in various ways, and also set up exceptions for important contacts.
The shell interface One UI from the company Samsung offers several levels of control over sound profiles. Understanding the difference between normal silent mode and complete blocking of notifications will help you flexibly configure the device to suit your needs without the risk of staying connected.
Quick shutdown via the notification panel
The fastest way to return your phone's ability to make calls is to use the notification shade. This method does not require deep diving into the settings menu and only takes a few seconds. Just unlock the screen and swipe down from the very top edge of the display.
In the panel that opens, you will see a row of quick settings icons. Among them you need to find the icon marked as Do Not Disturb. It usually looks like a crossed out circle or crescent. If the icon is highlighted in blue or white, it means the mode is active.
Tap this icon once to change its state to inactive. After this, the icon should turn gray or transparent, and the corresponding symbol will disappear from the top status bar. Now your smartphone will again respond to incoming calls in the standard way.
Sometimes the icon may be hidden behind an additional panel page. If you don't see the icon you want right away, swipe left or right across the button area to reveal the full list of available switches.
⚠️ Note: If you still don't see sound after disabling the icon, check the physical volume button. The media ringtone may have been set to minimum separately from the system silent mode settings.
Use a two-finger gesture to quickly minimize all notifications to quickly get to the quick settings panel at the top of the screen.
Deep customization through the options menu
For more detailed control of the sound blocking function, go to the main system configuration menu. This path allows you not only to turn off the mode, but also to understand exactly what rules were set previously. Go to the section Settings → Sounds and vibration.
In this section you will find the item Do Not Disturb. Clicking on it will take you to a menu with detailed options. This displays the current status of the feature and the time it will automatically turn on, if it has been scheduled.
To completely deactivate the feature, move the main switch at the top of the screen to the "Off" position. The system will instantly apply the changes, and all previously blocked notifications will begin to arrive as usual.
In the same menu, you can view the activation history or set up automatic rules. For example, the phone can turn on silence itself at a certain time of day or when connected to a specific location.
Control via the side panel and buttons
Modern models Samsung Galaxy are equipped with a convenient side panel that duplicates the functions of the notification curtain. You can call it by swiping your finger from the side of the screen to the center. This is especially convenient when using the phone with one hand.
On the toolbar, find the sound control icon. In some firmware versions One UI there is a separate button for cyclically switching modes: “Sound”, “Vibration”, “Silent” and “Do not disturb”. Press it until the lock icon disappears.
It is also worth paying attention to the combination of physical buttons. On some devices, repeatedly pressing the volume down button all the way down may activate vibration or complete silence mode. Check the button settings in the Settings → Accessibility → Improved visibilitysection to change this behavior.
- 🔘 Use the sidebar for quick access without unlocking the screen (if configured).
- 🔊 Make sure that the call volume slider is not in the far left position.
- 📵 Check to see if Airplane mode is activated, which also blocks communication.
⚠️ Attention: The sidebar interface may vary depending on the device model and version of the Android operating system installed.
Setting exceptions and priorities contacts
Often users do not want to completely disable silent mode, but only want to allow calls from certain people. The settings "Do not disturb" on Samsung provide a flexible exception mechanism.
Go to the function menu and find the section Permissions or Exceptions. Here you can select categories of notifications that will pass through the blocking. For example, you can allow only repeat calls: if the same subscriber calls twice within 15 minutes, the second call will go through.
You can also set it to skip calls from selected contacts. To do this, you must first add numbers to the “Favorites” list in the phone book. Then, in the silent mode settings, select the “Calls from favorites” option.
This allows you to sleep peacefully without the fear of missing an emergency call from close relatives or colleagues. The system will ignore advertising mailings and regular application notifications, but will miss important signals.
How do repeat calls work?
If the caller calls you a second time within 15 minutes, the system considers it an emergency and will skip the call, even if Do Not Disturb mode is active. This protects against missing urgent news.
Automatic modes and schedules
One of the common reasons for unexpected silence is the operation of automatic schedules. The smartphone can be configured to turn on the sound blocking mode at certain times, for example, at night or during classes.
To check for such rules, go to Settings → Modes and scenarios (in older versions Bixby Routines). All active automations are displayed here. Find a scenario associated with sleep time or a specific location.
Within the scenario, look for an action related to sound. If it says to turn on Do Not Disturb mode, you can edit the duration of its operation or remove the scenario completely. This will prevent automatic activation of silence at an inconvenient time for you.
Also check the section Digital Wellbeing. The Bedtime feature can force silent mode and turn the screen to black and white at specified hours. Disable this timer if it interferes with your communication.
| Schedule Type | Where to find | How to disable |
|---|---|---|
| Bedtime | Digital well-being | Turn off the "Sleep time" switch |
| Sleep mode | Modes and scenarios | Delete or change the "Sleep" scenario |
| Meetings (Calendar) | Calendar → Settings | Uncheck “Do not disturb mode” |
Automatic scripts are often the hidden reason for activating the silent mode, so checking them is mandatory when searching problems.
Solving problems and resetting sound settings
In rare cases, a software glitch can cause Do Not Disturb mode to freeze or not be turned off using standard methods. If the switches do not respond or the icon returns immediately after turning off, deeper intervention is required.
The first step is to restart the device. This will clear RAM and restart system services responsible for processing notifications. In most cases, this solves the frozen status problem.
If rebooting does not help, check for software updates. Go to Settings → Software update → Download and installation. The company Samsung regularly releases patches that correct errors in the interface One UI.
As a last resort, you can reset accessibility settings or sound profiles without deleting personal data. However, before doing this, you should make sure that third-party applications do not have rights to manage Do Not Disturb mode.
- 🔄 Completely restart your smartphone to reset temporary errors.
- 📲 Check the access rights of installed applications in the "Special Access" section.
- 🛠 Update firmware to the latest available version through the settings.
⚠️ Attention: Third-party memory cleaning applications or antiviruses may have their own silent mode settings that conflict with Android system settings.

Frequently asked questions (FAQ)
Why does the phone ring but the screen does not light up in Do Not Disturb mode?
This may be due to screen or power saving settings. Check to see if Ultra or Power Saver mode is enabled, which disables the Always On Display feature. Also make sure that Do Not Disturb exceptions allow visual notifications.
Can you turn off Do Not Disturb with a voice command?
Yes, if you have a voice assistant set up Bixby or Google Assistant. Just say: “Hey Bixby, turn off Do Not Disturb” or “Ok Google, turn off Do Not Disturb.” The phone will execute the command instantly.
Does Do Not Disturb mode affect the alarm clock?
By default, the system alarm clock Samsung should work even when the silence mode is active. However, if you are using a third-party alarm app, it may be blocked. Check the exception settings for a specific alarm clock application.
How to find out which application has enabled silent mode?
Go to Settings → Applications and select the three dots in the corner of the menu. Click Special Access → Do Not Disturb. There will be a list of applications that have permission to control this mode. Disable access for suspicious apps.
Why does the mode icon not disappear after a reboot?
Most likely, you have an automatic schedule or scenario activated in the “Modes and Scenarios” section. Also check if the Bedtime mode is enabled in your digital wellbeing settings, as it takes precedence over manual settings.
