How to hide notifications from the lock screen on Android 10: a complete guide

The lock screen on Android 10 is not just protection against accidental clicks, but also a potential “loophole” for prying eyes. Even if you use a password or fingerprint, notifications from instant messengers, email or social networks can display confidential information: sender names, message fragments, email subjects. In this article, we will look at all the available ways to hide notifications on a locked screen - from standard settings to hidden functions for advanced users.

The feature Android 10 is the flexibility of notification management: the system can be configured to completely hide all notifications, or to selectively display only important ones. But there are nuances: some manufacturers (Samsung, Xiaomi, Huawei) modify the standard interface by adding their own options. We will focus on “pure” Android 10 (for example, on Google Pixel or devices running the app Android One), but we will point out the key differences for popular shells.

If you have never looked at the notification settings, be prepared for surprises. For example, by default Android 10 can show the contents of messages from all applications, even if the screen is locked with a password. This applies not only to SMS, but WhatsApp, Telegram, Gmail and other services. Next, you will learn how to fix it in 2 minutes.

1. Standard notification privacy settings

The most obvious and secure way is to use the built-in system options. T Android 10 here they are hidden in the settings menu, but they are not difficult to find if you know the way. Here are the step-by-step guide:

1. Open the application Settings (gear in the menu or on the desktop).

2. Go to the section Applications and notifications → Notifications.

3. Tap on the item On the lock screen.

4. Select one of three options:

   • 🔒 Show all notification contents (default) - icons, application names and message text are displayed.
   • 🔐 Hide notification contents — only application icons and the number of new notifications are shown.
   • 🚫 Do not show notifications at all —the lock screen remains blank.

Option Hide the contents of notifications —the gold standard for most users. It allows you to see that a new message has arrived (for example, from Viber or Instagram), but does not reveal its contents. This is convenient if you often check your phone in public places, but do not want others to read your correspondence.

It is important to consider that these settings apply to all applications at once. If you need to hide notifications only from individual instant messengers (for example, Signal or Slack), proceed to the next section.

⚠️ Attention: On some devices (for example, Samsung Galaxy with shell One UI) the path to the settings may differ: Settings → Lock screen → Notifications. If you don’t find the item you need, use the search in the settings (magnifying glass icon at the top of the screen).

2. Selectively hide notifications for individual applications

If you need to leave notifications from Google Messages or Calendarbut hide messages from Facebook Messenger or Discord, use individual settings for each application. This method works even on customized firmware (MIUI, ColorOS etc.).

Action algorithm:

1. Go to Settings → Applications and notifications.

2. Select the application whose notifications you want to hide (for example, Telegram).

3. Tap on the item Notifications (or Alerts on some devices).

4. Find the section On the lock screen and select:

   • 🔍 Show notifications (with or without content).
   • 🚫 Do not show notifications.

For example, for Gmail You can leave the option Show. notifications, but select Hide contentso that only “New message from [address]” is displayed on the lock screen, and not the subject and text of the message. Alternatively, you can completely disable the display of notifications on the locked screen. WhatsApp You can also completely disable the display of notifications on the locked screen.

Some applications (for example, Slack or Microsoft Teams) have their own privacy settings inside the app. To find them:

1. Open the application.

2. Go to its settings (usually through the profile icon or three dots in the menu).

3. Find the section Notifications → Privacy or Lock screen.

⚠️ Attention: After updating the application, its privacy settings may be reset to default values. Check them after each major update (especially important for Facebook Messenger i VK).

3. Using Do Not Disturb mode to temporarily hide

If you need to hide notifications on the lock screen only at certain times (for example, in a meeting or at the movies), use the Do Not Disturb (DND)mode. It allows you to flexibly. set up rules for displaying notifications, including the lock screen. Android 10 it allows you to flexibly configure the rules for displaying notifications, including the lock screen.

How to enable:

1. Open the quick settings panel (swipe down from the top edge of the screen).

2. Find the icon Do not disturb (usually depicted as a crossed out bell) and hold it for 1-2 seconds.

3. In the menu that opens, select Settings → Rules.

4. Create a new rule or edit the existing one by specifying:

   • 🕒 Action time (for example, from 20:00 to 8:00).
   • 🔕 Type notifications: select No sounds and no vibration or Only important.
   • 🔒 Lock screen: check Hide notifications.

The advantage of this method - automation. For example, you can set up a rule that will be activated according to a schedule (daily from 22:00 to 7:00) or when connected to a specific Wi-Fi network (for example, at work). At the rest of the time, notifications will be displayed as usual.

Please note: in mode Do not disturb can be configured exceptions. data-i="168">4. Hiding sensitive notifications through security settings. For example, allow notifications from Google Clock (alarm clock) or repeated calls from one contact. This is useful if you do not want to miss an important call, but at the same time hide all other notifications.

4. Hide sensitive notifications through security settings

V Android 10 there is a little-known feature that allows you to hide notifications from all applicationsmarked as "sensitive". These include instant messengers, banking applications, email clients and other services that work with personal data. This method is useful if you want to automatically hide notifications from applications that could potentially contain sensitive information.

How to enable:

1. Go to Settings → Security → Additional settings (the path may differ on some devices).

2. Find the item Notifications on the lock screen or Notification privacy.

3. Activate the option Hide sensitive content.

After activation, the system will automatically hide notification text from applications that:

• 🔐 Have access to SMS or calls (for example, Truecaller).
• 💳 Are working with payment data (Google Pay, SberBank Online).
• 📧 Manage mailboxes (Gmail, Yandex Mail).
• 💬 Are messengers (Viber, Skype).

This method is convenient because it does not require manual configuration of each application. However, it does not provide flexibility: you cannot choose which “sensitive” notifications to hide and which not. For example, if you want to see notifications from WhatsAppbut hide from Tinder, this method will not work.

5. data-i="198">If the standard settings do not suit you, you can go further - use

If the standard settings do not suit you, you can go further - use ADB commands or third-party utilities. These methods are suitable for experienced users who are willing to sacrifice security for additional control.

Method 1: Disable notifications via ADB

Using Android Debug Bridge (ADB) you can completely block the display of notifications on the lock screen for all applications. To do this:

1. Connect your phone to the PC and enable USB Debugging in the developer settings.

2. Open the command line on your computer and enter:

adb shell settings put global lock_screen_show_notifications 0

To get everything back, use:

adb shell settings put global lock_screen_show_notifications 1

B Google Play there are utilities that expand the capabilities of managing notifications. For example:

• 🛡️ Notification History Log —keeps a log of notifications and allows you to filter their display.
• 🔧 AutoNotification (requires Tasker)—creates complex rules for displaying notifications.
• 🔒 Lockscreen Notifications —suggests flexible settings for the lock screen.

⚠️ Attention: Using ADB or third-party applications may disrupt the stability of the system, especially if you change system settings. Before experiments, create a backup copy of your data. In addition, some applications for managing notifications require permission Accessibility Service, which is potentially dangerous (attackers can intercept your data).

7. Checking the result and fixing problems

After applying any changes, check how notifications are now displayed.

1. Lock the screen (with the power button or gesture).

2. Ask a friend to send you a test message in the messenger or send yourself an email.

3. Unlock the screen and compare what was displayed before and after the changes.

If notifications are still not shown correctly, check:

• 🔄 Application cache: sometimes cache reset for Settings or System UI helps to apply changes. To do this, go to Settings → Applications → Show system → Settings → Storage → Clear cache.
• 📱 System updates: on some devices, bugs with notifications are fixed in new firmware versions.
• 🔧 Conflicting applications: antiviruses (for example, Avast) or launchers (for example, Nova Launcher) may override notification settings.

If you are using Android 10 on a rooted device, the cause of the problem there may be a modified system file. In this case, try:

1. Install the original SystemUI.apk.

2. Check the settings in Xposed Framework (if used).

⚠️ Attention: On some devices (for example, Samsung Galaxy c One UI 2.0) after a factory reset, the notification settings on the lock screen may be reset to default values. Before resetting, write down the current settings or take screenshots.
