Modern smartphones based on the operating system Android have become an integral part of our lives, providing instant access to information. However, the constant stream of notifications, sounds and system messages can seriously irritate the user, especially at inopportune moments. It is often necessary to remove intrusive sounds or completely deactivate certain types of alerts in order to focus on important matters.
The process of disabling alerts may vary depending on the version of the operating system and the shell installed by the manufacturer. Whether it Samsung One UI, Xiaomi MIUI or pure Android from Google, the basic principles remain similar, but the paths to the desired settings may differ. In this article, we'll take a closer look at all the possible ways to manage system and user notifications.
It's important to understand the difference between regular app notifications and system alarms, such as Cell Broadcast or disaster alerts. Some of them can be disabled completely, while others, especially those related to emergency services, may not be deactivable without special rights or deep intervention into the system.
The difference between app notifications and system alarms
The first step to quieting your device is to understand the nature of the incoming alarms. Application notifications generated installed apps: instant messengers, social networks, games and news aggregators. They appear in the notification shade and are often accompanied by a sound or vibration. They are managed through the settings of each specific application or through the central notification menu.
In contrast, system alerts come directly from the operating system or are broadcast through the cellular network by the telecom operator. These include warnings about low battery, computer connection, security updates, as well as emergency messages Cell Broadcast about emergencies in the region. These signals have higher priority and are often ignored by Do Not Disturb modes.
For effective control, the source of the signal must be clearly identified. If you're bothered by a constant sound when you receive an email, that's one thing. If we are talking about a loud siren-like sound that occurs once a month or when testing the system, the approach should be different. Ignoring these types can lead to the fact that you turn off important work notifications, trying to remove the system sound.
Before changing the settings globally, watch the phone for a couple of days: write down at what exact moment and for what action the annoying sound appears. This will help you find the exact source of the problem.
Configuring application notifications through the system menu
The most common source of noise is applications. Android provides powerful tools to control them. Starting from version Android 8.0 Oreo, the notification channel system allows you to flexibly configure which events can interrupt the user and which should arrive silently.
To access these settings, you need to go to the application management section. Here you will see a complete list of installed software. Select the app you want, such as a social network or game, and find the Notifications option. Inside this section, a detailed breakdown of event types is often hidden.
- 🔔 Notification categories: Inside the application, you can disable only certain types, for example, “Recommendations” or “Games”, leaving personal messages active.
- 🔇 Silent mode: You can allow the icon to be displayed in the curtain, but prohibit the playback of sound and vibration for specific categories.
- 🚫 Full blocking: A radical method that completely hides any signs of attention from the selected application.
Pay attention to the “All notifications” switch at the top of the settings menu for a specific application. If you turn it off, the application will no longer be able to harass you in any way. This is useful for rarely used apps that you do not want to delete.
☑️ Checking application settings
Managing emergency alerts and Cell Broadcast
The so-called “Emergency Alerts” deserve special attention. This is a state warning system for the population, working through technology Cell Broadcast. It is intended to inform about threats to life: tsunamis, earthquakes, terrorist attacks or testing a communication system. The sound of these alerts is often described as high-pitched and frightening.
In most regions, users have the ability to turn off some of these notifications, with the exception of those marked as “Emergency Threat” or “Presidential Alert” (in the US), which are technically impossible to turn off without modifying the firmware. Settings are usually found under Security or Apps & Notifications.
⚠️ Attention: By turning off emergency alerts, you risk missing out on critical information about dangers in your area. Do this only if the system testing sound makes you panic or bothers you at a particular moment, and be sure to turn them back on later.
The path to the settings may look like Settings → Applications and notifications → Advanced → Wireless emergency alerts. In some shells, for example on Xiaomi or Samsung, this item may be placed in the “Security” or “SIM cards and mobile networks” section. Inside you will see a list of alert types with switches.
| Alert type | Description | Ability to disable |
|---|---|---|
| Emergency threat | Immediate danger to life (tsunami, fire) | Often unavailable |
| AMBER Alert | Search for missing children | Available |
| Test message | Checking system functionality | Available |
| Notification of a radiation accident | Threat of radiation contamination | Depends on the region |
If you cannot turn off the sound using standard methods, you can try temporarily turning on airplane mode, but this will deprive you of communication. A softer option is to use third-party profile management apps, which can automatically turn on Do Not Disturb mode at certain times, although system alerts may bypass them.
Do not disturb modes and sound profiles
The built-in concentration modes are ideal for temporarily solving the noise problem. Mode "Do Not Disturb" (Do Not Disturb) allows you to create a whitelist of contacts and applications that can break through the blocking, while all others, including system sounds (except the alarm clock), will be muted.
You can configure this mode through quick settings in the curtain or in menu Settings → Sound and vibration → Do not disturb. This sets the rules: who can call, whether repeat calls (if a person calls twice in 15 minutes) can go through, and what visual effects are allowed. This is a great way to ensure silence during sleep or a meeting.
In addition, many manufacturers implement their own “Profiles” or “Scenarios”. For example, Samsung has the “Work”, “Home”, “Meeting” modes. You can set up a scenario so that when connected to the office Wi-Fi network, the phone automatically goes into silent mode with vibration, ignoring all unnecessary notifications.
- 🌙 Sleep mode: Automatically activates at night, mutes the screen and blocks all sounds except the alarm clock.
- 💼 Work profile: Separates personal and work applications, allowing you to turn off notifications only from work apps on weekends.
- 🎮 Game mode: Blocks pop-up windows and sounds when launching games, so as not to interrupt the process.
Using these tools is much more effective than full turning off the sound by the speaker, as it allows you to maintain control over the situation. You won’t miss an emergency call from a loved one if you add it to the exceptions, but you will get rid of the information noise.
The secret of repeated calls
The “Do Not Disturb” mode setting has the “Repeat calls” function. If the same number rings a second time within 15 minutes, the phone will ring. This saves you in situations when someone is trying to reach you on an urgent matter while you are sleeping.
Disabling system interface sounds and actions
Often users are annoyed not so much by notifications as by the sounds of the interface itself: keyboard clicks, screen locking sounds, beeps when charging or connecting a USB. These sounds are classified as system sounds and are controlled separately from media volume.
To remove them, go to Settings → Sound and vibration → System sounds (or “Other sounds”). Here you will find switches for each action type. By turning them off, you will make interaction with your smartphone absolutely silent, which is especially important in cinemas or libraries.
It is also worth checking your keyboard settings. Often, keypress sounds are enabled by default. To disable it, you need to go to the settings of the keyboard itself (usually through the gear icon on the keyboard panel or in the general language and input settings) and find the “Sound when pressed.”
Do not forget about navigation sounds - clicks when dialing a number in the dialer or Touch-tone sounds when entering passwords. They are also located in the system sounds section. Completely disabling these elements makes using the device more comfortable and less intrusive.
The system sounds of the interface do not depend on the volume of the media or ringtone. They must be disabled separately in the corresponding subsection of the sound settings.
Using ADB for advanced control
For advanced users who want to achieve absolute control, there is a tool ADB (Android Debug Bridge). With its help, you can disable system components responsible for alerts, or change hidden settings that are not available in the regular menu. However, this method requires caution.
To work, you must enable “Developer Mode” and “USB Debugging” in the phone settings, as well as install drivers and the ADB platform on your computer. Once your phone is connected, you can send commands to change global settings.
adb shell settings put global zen_mode 2This command, for example, puts the phone into “Complete rest” mode, blocking all notifications. You can also use commands to disable specific system applications if they are the source of the problem, but this requires knowing the exact package name.
⚠️ Attention: Using ADB commands can lead to system instability or data loss if you are not sure of your actions. Always check the syntax of commands and understand their purpose before executing them.

There are also graphical shells for ADB, such as ADB AppControl or Universal Android Debloaterthat simplify the process. They allow you to see a list of all applications and safely disable system components responsible for unnecessary notifications with one click.
Frequently asked questions (FAQ)
Is it possible to disable emergency alerts on an iPhone?
Yes, you can also disable most test and warning alerts on an iPhone. Path: Settings → Notifications, scroll to the very bottom to the “Government Alerts” block. There you can turn off "Disaster Alerts" and "Emergency Alerts", but "Emergency Alerts" (maximum threat) cannot be turned off.
Why does the alert sound sound even when silent mode is on?
System High priority alerts (especially Cell Broadcast) often ignore silent and do not disturb settings as they are intended to save lives. You can disable them only in special settings for wireless alerts, if this is permitted by the laws of your country.
How to turn off the charging sound on Android?
The charging sound refers to system sounds. Go to Settings → Sound → System sounds (or "Other Sounds") and find the "Charging" or "Connect to Power" switch, then turn it off. On some models, this option may be hidden.
Does turning off notifications affect the operation of the alarm clock?
No, the standard Do Not Disturb and mute modes do not affect the operation of the built-in alarm clock. The alarm clock has the highest priority and will work even when the phone is turned off (if it was set before it was turned off and the phone turns on according to a schedule, which not all models support) or in airplane mode.
What to do if the notification settings are lost after updating Android?
After major OS updates, the settings may be reset or moved. Check the Notifications section in Settings again. If the problem is the Cell Broadcast menu disappearing, try resetting your network settings or contact your carrier, as some settings may be managed through your carrier profile.
