Pop-up banners, sudden transitions to the application store and intrusive notifications can turn the use of a modern smartphone into a real challenge. Many users are faced with a situation where advertising junk appears not only in the browser, but also directly on the desktop, covering important interface elements. This is not just annoying, but also significantly reduces the performance of the device, using up battery power and mobile traffic.
Fortunately, the operating system Android provides flexible enough tools to combat this phenomenon without the need to obtain root access or purchase expensive subscriptions. In this material we will look at the most effective methods, ranging from simple settings in the menu to advanced methods of filtering traffic. You will learn how to identify a malicious application and permanently block unwanted content.
Before taking drastic measures, it is worth understanding the nature of advertising. Most often, the culprits are free utilities that you installed recently, or aggressive browser settings. Sometimes the source of the problem is the smartphone manufacturer itself, which introduces promotional materials into the system shell. Having understood the mechanism of operation of these processes, you can specifically eliminate the cause, rather than fight the effect.
Identifying and removing culprit applications
The most common reason for pop-up windows appearing on top of other applications is the installation of a app with a hidden advertising module. Such utilities are often disguised as useful tools: flashlights, QR code scanners, memory cleaners, or simple games. They may not have an icon in the application menu, which makes them difficult to find through the standard interface.
To find a hidden parasite, you need to go to the device settings and open the app management section. Look for an app that doesn't have a title or the icon is a blank white square. Often such apps are located at the very bottom of the list or, conversely, at the top if they were recently installed. If a suspicious object is detected, it must be uninstalled immediately.
If the standard menu does not show obvious signs of malware, use the application manager to analyze the resources consumed. Go to section Settings → Applications → Special access → Display on top of other applications. Here you will see a list of apps that have the right to display content on top of the desktop. Carefully study this list:
- 🔍 Check for unknown names or apps with suspicious permissions.
- 🚫 Disable the right to display on top of other windows for all unnecessary utilities.
- 🗑️ Uninstall applications that you do not remember or that were installed before the ad appeared.
⚠️ Attention: Some Google system services may also have this permission, but it is not recommended to disable them, as this will disrupt the functionality of notifications and widgets. Remove only third-party software.
☑️ Diagnosis of hidden advertising
Sometimes a malicious app gains device administrator rights, which blocks the delete button in the normal menu. In this case, you need to go to the security section and find the item Device administrators. Uncheck the suspicious application, then return to the app management menu and follow the standard uninstallation procedure. This action will deprive the virus of its privileges and allow you to clean the smartphone.
Disable personalized advertising in Google settings
Even after removing viruses, you can continue to see advertisements in Google services, the Play Market and other official applications. These are legal advertisements that are targeted based on your search history and online behavior. You can’t completely remove it, since this is the main way to monetize free services, but you can reset the advertising identifier and disable personalization.
To do this, open your phone settings and find the section dedicated to privacy or Google account. The path may differ depending on the version Android and shell manufacturer, but usually it looks like Settings → Google → Advertising. In this menu, you will find a switch responsible for using the identifier to show relevant ads.
Disabling this feature will not make the screen completely clear, but the ads will become less intrusive and will no longer track your interests. In addition, a reset advertising identifier button is available here. Regular use of this option confuses data collectors' algorithms, making your digital profile less clear to marketers.
| Action | Effect | Difficulty |
|---|---|---|
| Reset ad ID | Disconnects with accumulated interest profile | Low |
| Disable personalization | Advertising becomes random and not targeted | Low |
| Deleting action history | Clears the database of your search queries | Medium |
| Revoke consents in Activity | Prohibits saving location and application data | High |
Change your advertising identifier periodically (once every 1-2 months) so that the algorithms do not have time to build a stable profile of your preferences. This is especially true before purchasing expensive goods.
It is also worth looking into the Google Play security center. In the menu Play Market → Profile → Settings → General → Security Center you can check whether installed applications have permission to display advertising in system notifications. Although this is a rare scenario for certified applications, double-checking will not be superfluous.
Blocking ads via private DNS (the most effective method)
One of the most powerful and yet easiest ways to get rid of from advertising in all applications and browsers is the use of the Private DNS (Private DNS) function. This technology, available starting from Android 9, allows you to redirect all device requests to a server that automatically filters out advertising domains before they load on the screen.
You do not need to install additional software or obtain advanced access rights. Just go to the network settings. The path to the desired menu is usually as follows: Settings → Connections → Other connection settings → Private DNS. On some models Xiaomi or Samsung this item may be located in the advanced Wi-Fi settings or in the "Connections and sharing" section.
Select the "Hostname" mode provider" (or "Manually") and enter the address of a reliable blocker. The most popular and stable solution is the AdGuard DNS service. In the input field you must enter the following line:
dns.adguard.comAfter saving the settings, the device will redirect all DNS requests through the filters of this service. Banners in free games, pop-ups in browsers, and analytics trackers will stop loading. This will significantly speed up the Internet and save traffic, since advertising content simply will not be downloaded to the phone.
The Private DNS method blocks advertising at the level of the entire system, including applications where built-in blockers are often powerless. This is the best free solution today.
⚠️ Attention: If after enabling this function some sites or applications no longer open, try changing the address to dns-family.adguard.com or temporarily disabling the setting. In rare cases, some legitimate services may conflict with filters.
It is important to understand that this method is not a panacea for video hosting sites like YouTube. Ads inside video streams are often loaded from the same domains as the video itself, so DNS filtering will not work there. However, for web surfing and most mobile utilities, the effectiveness of this method reaches 90-95%.
Setting up a built-in blocker in the Chrome browser
For many users, the main source of annoying banners is the mobile browser. Google Chrome, which is installed by default on most smartphones, has built-in protection mechanisms against annoying ads and pop-ups, but they are often disabled by default or not configured strictly enough.
To activate protection, open the browser, click on the three dots in the upper right corner and go to Settings → Site Settings. Here you are interested in two main points: “Pop-ups and redirects” and “Advertising”. Make sure the slider next to pop-ups is in the "Blocked" position.
The "Advertising" section allows you to block ad formats that block content or automatically play sound. Enabling this option makes browsing sites much more comfortable. However, it is worth remembering that this will not remove all banners, but only those that violate the Better Ads Standards coalition.
- 🛡️ Activate pop-up blocker for all sites.
- 🔇 Prevent automatic playback of sound and video.
- 🚫 Enable the filter against intrusive advertising in the content settings.
If built-in tools is not enough, consider installing specialized browsers such as Brave or DuckDuckGo. They have aggressive built-in shields that cut out ads and trackers on the fly without the need for additional configuration. This is a great alternative for those who don't want to tinker with system settings.
Alternative Browsers
The Brave browser uses Brave Shields technology, which blocks tracking scripts and ads by default. This can speed up page loading up to 3 times compared to regular Chrome, but sometimes it can break the layout of some sites.
Managing notifications from system applications
A separate layer of problems consists of push notifications from system applications of the smartphone manufacturer. Companies like Xiaomi, Samsung or Huawei often use their services (for example, GetApps, Galaxy Store, Mi Video) to promote games and products directly to the notification shade. These messages are legal from the system's point of view, so antiviruses do not see them.
You need to combat them through detailed notification settings. Go to Settings → Applications and find suspicious system utilities: “Security”, “Cleaning”, “Music”, “Video”, “Themes”. Go to each of them and select "Notifications".
Inside you will see many categories: "Recommendations", "Promotions", "News". Ruthlessly turn off all marketing-related toggle switches, leaving only critical alerts (for example, when a virus scan is completed). This action will return silence to your notification panel.
⚠️ Attention: The MIUI, OneUI and EMUI shell interfaces are constantly changing. If you can't find the switch you need, use the settings search by entering the word "Notifications" or the name of a specific application.
It's also worth checking the "Accessibility" or "Recommendations" section in the main phone settings. Manufacturers sometimes hide general switches there such as “Get recommendations” or “Personalized offers”. Disabling these global settings can remove advertising from several system applications at once.
Frequently asked questions and additional security measures
Even after completing all the steps described above, situational questions may arise related to the features of specific models or software versions. Below are answers to the most popular user requests that will help bring the protection of your device to the ideal.
Will installing an antivirus help remove ads?
Modern mobile antiviruses (Kaspersky, ESET, Dr.Web) have “Anti-banner” or “Web protection” modules that can block ads in the browser and some applications. However, they are not always effective against the manufacturer's system advertising. It is better to use them in conjunction with setting up Private DNS.
Why do ads appear after installing a specific application?
Most likely, you have given this application permission to create notifications or display on top of other windows. Check access rights in the application settings and revoke unnecessary permissions. If the problem persists, it is better to delete the application.
Is it possible to remove advertising on YouTube for free?
Officially - no. DNS filtering and browser blockers do not work inside the official YouTube application, since advertising is loaded from the same servers as the video. Blocking requires the use of modified clients (which violates the terms of service) or the purchase of a Premium subscription.
Is it safe to use third-party DNS addresses?
Using proven services such as AdGuard DNS or Cloudflare (1.1.1.1) is completely safe. They only process requests for domain names. However, do not enter the addresses of dubious servers found on forums, as they could theoretically redirect your traffic.
What to do if advertising returns after a system update?
Major updates to Android or the manufacturer's shell may reset some settings to factory settings. Check the Private DNS status and system application notification settings again. Also update the applications themselves through which advertising is sent to the latest version.
