The lock screen of modern smartphones Samsung Galaxy has become a powerful information hub that instantly reports new emails, instant messenger messages and system events. However, too many notifications can clutter up useful space, hide important widgets, or simply irritate the owner who wants to maintain privacy. The issue of privacy is especially relevant when the phone is on a table in a public place, and any passerby can read the contents of a personal message.
The operating system Android in the shell One UI provides flexible tools for managing this flow of information. The user can not only completely disable the display of notifications, but also customize their appearance: hide the text, leave only icons, or allow display only for selected applications. In this article, we'll take a detailed look at all the available customization methods, from simple switches to advanced automation scripts.
You don't need to be an IT expert to get your lock screen in order. Just go to the appropriate settings section and choose the best option for yourself. Below are step-by-step guide that will help you configure the device to suit your own security and comfort needs.
Global settings for display on the lock screen
The easiest way to control the flow of information is to use the system security settings. This method allows you to set a single rule for all applications at once, without going to the menu of each of them separately. To begin, unlock your device and go to the main settings menu.
Find the section Lock screen. Depending on the version One UI, this item may be located directly in the top menu or inside a category Biometrics and security. Here is a switch Notifications, which is responsible for globally enabling or disabling the display of notifications.
If you want to completely clear the screen of any attention signs, simply turn off this toggle switch. However, the system offers more fine-tuning. By clicking on the text of the item Notifications (and not on the switch), you will be taken to a menu of detailed content visibility settings.
⚠️ Attention: Completely turning off notifications on the lock screen may cause you to miss important calls or urgent messages while the phone is in your pocket or bag.
In the detailed settings menu you will see three main options for system behavior:
- 📢 Show contents: the application icon, title and full text of the message are displayed on the screen.
- 🔒 Hide content: only the application icon and title are visible, but the message text is replaced with dashes or an inscription "Hidden content."
- 🚫 Do not show notifications: The lock screen remains completely blank, no icons appear.
Choosing the option Hide content is the golden mean for most users. You immediately see that a new message has arrived, for example, from Telegram or WhatsApp, but strangers cannot read its essence without unlocking the device.
Individual settings for specific applications
Sometimes global disabling is inconvenient, because you want to see messages from loved ones, but don’t want to advertise notifications from games or news aggregators. In this case, fine tuning is necessary. The system Android allows you to control the behavior of each application individually.
To do this, return to the menu Settings → Notifications. Here you will find a list of all installed apps that have permission to send alerts. Scroll down the list and select the desired application, for example Instagram or Gmail.
Inside the menu of a specific application, find the section Lock screen. Here you can override global settings. Even if you have the "Hide content" mode set for the entire system, for this particular application you can select "Do not show notifications."
This approach is useful for clearing the interface of visual noise. Users often forget to turn off notifications from long-deleted games or food delivery services that continue to send advertising push notifications.
☑️ Notification audit
Please note that some system applications may not have a separate switch for the lock screen if they are subject to strict device security policies. In such cases, changes are applied only through global settings.
Using Do Not Disturb mode for silence
Mode Do not disturb (Do Not Disturb) is a powerful tool that allows you to temporarily hide all notifications not only with sound, but also visually. This is an ideal solution for meetings, sleep at night or time when you need to concentrate.
You can activate this mode through the quick settings panel by swiping from top to bottom twice and clicking on the icon with a crossed out circle. However, for fine-tuning, you need to go to Settings → Notifications → Do Not Disturb.
In the parameters of this mode there is a section Hide visuals. Here you can configure the behavior of the lock screen while the mode is active. You can select the option Hide notificationsto keep the screen clear even if applications continue to run in the background.
An important feature is the ability to create exceptions. You can configure the system so that even in Do Not Disturb mode, only repeated calls or messages from selected contacts are displayed on the lock screen.
| Event Type | Standard Behavior | In Do Not Disturb Mode | Custom Exception |
|---|---|---|---|
| Incoming call | Sound + Screen | Silent + Vibration | Only from selected ones |
| Messenger message | Icon + Text | Hidden (curtained) | No (usually hidden) |
| Alarm clock | Sound + Screen | Sound + Screen (always) | Not configurable |
| System event | Icon | Hidden | No |
Using a schedule for this mode allows you to automate the process. For example, the phone itself will go into notification hiding mode every night from 23:00 to 07:00, providing you with a restful sleep and a clean screen in the morning.
Configure automatic activation of Do Not Disturb mode by geolocation. The phone will hide notifications when you come to the office or library.
Hide sensitive content through biometrics
Modern smartphones Samsung are equipped with advanced biometric security systems. The function Hide content can work intelligently, reacting to whether the device owner is looking at the screen.
This function is closely related to the operation of the proximity sensor and front camera. If the option is activated in the security settings Show details only when unlocked, then the phone will show the full text of the message only after successful scanning of the face or fingerprint.
Until authentication, only a blank will be visible on the screen. This is especially convenient when the phone is face up: you can see that there is a new letter, but to read it, you need to touch the sensor or look at the device.
To activate this function, go to Settings → Lock screen → Notifications and make sure that the mode Hide contentis selected. Then check the biometrics settings in the Biometrics and securitysection to make sure that face or fingerprint recognition works correctly.
⚠️ Attention: The function of hiding content before unlocking may not work if you use an unreliable unlocking method, for example, a simple pattern or PIN code without biometrics.
It is also worth considering that when using a mask or in the dark, facial recognition may be difficult, and the phone will remain in hidden view mode until you enter the password manually.
Setting up pop-up notifications and banners
In addition to static icons on the lock screen, there is a category pop-up notifications. They appear on top of the current screen or lock screen as a banner and disappear after a few seconds. They can also be controlled.
To remove these intrusive banners, go to the settings of a specific application through the menu Applications. Select the desired service, go to the section Notifications and find the category of notification channels (for example, "Private messages" or "Calls").
Click on the category name (not the switch) to open additional settings. Here you will see an option Pop-up notification. Disable it, and the message will only come to the curtain or to the lock screen, without interrupting your current activities with a bright flash.
This is especially true for video players and games, where the sudden appearance of a banner can block an important part of the image or lead to an accidental click.
Why notifications still appear?
Sometimes applications create new notification channels after updates. If you notice new pop-ups, check your application settings again - there may be a new type of alert that is turned on by default.
The system One UI also allows you to customize the display style of these banners: they can be brief (disappear quickly) or detailed (stay on the screen until you interact with them). The choice depends on your reaction speed and need for information.
Advanced methods: Good Lock and Bixby scripts
For users for whom standard settings are not enough, the company Samsung offers a module Good Lock and its plugin LockStar. This is an official customization tool that allows you to change the appearance of the lock screen beyond recognition.
Using LockStar you can completely redraw the notification interface. You can reduce the font size, change the transparency of the background, move icons to another corner of the screen, or even hide them visually, making them transparent, leaving the functionality working.
Another powerful tool is Modes and scenarios (formerly Bixby Routines). Here you can create an automatic rule. For example: “If Bluetooth headphones are connected, then turn off notifications on the lock screen.”
The algorithm for creating a scenario is simple:
- Open
Settings → Modes and scenarios. - Click Add mode.
- In the condition, select "Device connected" (headphones or watch).
- In the action, select "Lock screen" and set the "Notifications: Hide" option.
This approach allows automate privacy. When you put on headphones and go for a walk, the phone itself hides personal messages from prying eyes. When you return home and take off the headphones, notifications become visible again.
Using automation scripts allows you to change the visibility of notifications dynamically, depending on the context in which you are using the phone, without the need to manually switch settings.
Frequently asked questions (FAQ)
Why notification settings after updating Android reset?

Is it possible to remove only application icons, leaving the text?
Standard means Android this cannot be done. The system always displays the application icon along with the text. Removing the icon, leaving only the text, is only possible using third-party launchers or Good Lock modules, which change the system interface.
How to remove notifications from already deleted applications?
If an application is deleted, but its notifications hang on the lock screen, try restarting the device. If this does not help, go to Settings → Applications, find system services in the list (for example, Google Play Services) and clear their cache.
Does disabling notifications on the lock screen affect the operation of the alarm clock?
No, disabling visual notifications on the lock screen does not affect the operation of the alarm clock. The alarm clock is a system priority process and will always work with sound and turning on the screen at the appointed time, regardless of privacy settings.
Why is the camera or phone icon not visible on the locked screen?
Shortcut shortcuts (camera, phone) are configured separately from notifications. Go to Settings → Lock screen and find the section Shortcuts. Make sure the switches for the apps you want are enabled. They may also disappear if the power saving mode is turned on.
