Constant pop-ups, intrusive banners in the browser and sudden advertising integrations in system applications can turn the use of a modern smartphone into a real nightmare. Many users perceive this as a necessary evil, believing that a free operating system Android has to contain advertising for monetization. However, this is a dangerous misconception that deprives you of control over your own device.
In fact, there are many proven methods to completely block the flow of visual noise. From simple settings private DNSavailable to every smartphone owner, to more advanced methods using specialized software. In this article, we will analyze in detail the algorithms of actions that will help you return a clean interface and speed up the operation of your gadget.
Before taking radical measures, it is important to understand the source of the problem. Advertising can be broadcast by the browser itself, a specific application, or even be built into the firmware by the manufacturer. Correct diagnosis of the source will allow you to choose the most effective method of combating without unnecessary actions.
Using a private DNS for global blocking
The most effective and least resource-intensive method is to set up a private DNS server. This method does not require the installation of third-party applications and works at the level of the entire operating system, filtering traffic before it even reaches your screen. The technology DNS-over-TLS encrypts requests, preventing the provider or malicious scripts from replacing website addresses with advertising servers.
To activate this function, you do not need superuser rights or complex manipulations. Just go to the network settings of your device. The path may vary slightly depending on the model, but usually it looks like this: Settings → Connections → Other connection settings → Private DNS. In some shells, for example MIUI or ColorOS, this item may be located in the “Advanced settings” section.
After entering the menu, select the “ISP Hostname” mode DNS" (or "Manual"). In the field that appears, you must enter the address of a reliable blocker. The most popular and stable solution is the service AdGuard DNS. Enter the following line:
dns.adguard.comSave the settings. Your phone will now automatically reject requests to known ad servers. This will remove banners not only in the browser Chrome, but also in many free games and utilities that use standard advertising networks for monetization.
⚠️ Attention: After enabling private DNS, some applications that use aggressive advertising as the only source of income may stop launching or work incorrectly. If a critical application stops functioning, temporarily disable this setting.
If you are unable to connect to the Internet after entering the DNS address, check that the domain is spelled correctly. Extra spaces or typos in one letter can lead to a complete lack of access to the network.
Cleaning from malicious applications and hidden miners
Often, the source of intrusive advertising is not system services, but accidentally installed apps. Users can download a “memory cleaner,” “flashlight,” or “battery optimizer,” which turns out to be spyware or miners. Such applications often do not have an icon in the menu, but continue to work in the background, generating pop-up windows on top of all other apps.
The first step in the fight against such evil is a thorough audit of the installed software. Go to the Settings → Applications section and carefully review the entire list. Look for apps with no name, no icon, or a suspiciously simple name that you don't remember installing. Pay special attention to applications that you gave permission to “On top of other windows.”
- 🔍 Check the list of recently installed apps and remove everything that appeared before the problems with advertising began.
- 🛡️ Scan your device with the built-in antivirus Google Play Protect or a third-party solution from a reliable vendor.
- 🚫 Revoke administrator rights from suspicious applications in the menu
Security → Device administrators.
If you find an application that is not removed in the standard way (button “Delete” is inactive), most likely it has received administrator rights. You need to first go to the security settings, find this application in the list of administrators and revoke the rights. Only after this procedure the delete button will become active.
☑️ Malware diagnostics
Settings built-in browser and tracker blocking
Even if system advertising is disabled, web surfing can remain a source of irritation. Most mobile browsers have built-in security mechanisms, which are often disabled by default or set to a minimal level. The correct browser configuration Chrome, Firefox or Samsung Internet can block up to 90% of banners on visited sites.
In the browser Google Chrome go to settings and find the “Privacy and Security” section. Activate Safe Browsing and make sure the pop-up blocker option is turned on. However, standard browser tools often miss native advertising. For deeper cleaning, it is recommended to use specialized extensions or switch to browsers with a built-in blocker, such as Brave or DuckDuckGo.
For users who prefer to remain in the ecosystem Google, it is possible to install extensions through special versions of the browser or use DNS filtering, which was mentioned above. It is also important to regularly clear cookies and cache, as advertising networks use them to target and re-serve ads.
| Browser | Built-in protection | Support for extensions | Recommendation |
|---|---|---|---|
| Chrome | Basic | No (on mobile) | Use with DNS |
| Firefox | Enhanced | Yes (uBlock Origin) | Excellent choice |
| Samsung Internet | High | Yes (via plugins) | Recommended |
| Brave | Maximum | No (custom engine) | Best of the box |
Do not forget that some sites may require blockers to be disabled in order to display content correctly. In such cases, it is convenient to use the “White List” function, adding trusted resources to exceptions in order to support the authors of the resource without sacrificing security on other pages.
Disable personalized advertising on Google
The Corporation Google collects a huge amount of data about your preferences in order to show relevant advertising in the company's services, including YouTube, Gmail and search results. While it's impossible to completely remove ads from Google's free services without a subscription, you can turn off personalization. This will not reduce the number of banners, but will make them random and less intrusive. YouTube Premium is not possible, you can disable personalization. This won't reduce the number of banners, but it will make them random and less intrusive.
To manage your advertising settings, follow the path Settings → Google → Advertising. Here you'll find a toggle for "Turn off ad personalization." Activating this setting resets your advertising identifier GAID (Google Advertising ID), breaking the connection between your search history and the ads that are shown.
It is also recommended to go to the “My Google Activity” section through your account and disable the saving of activity history in applications and web services. This will prevent the accumulation of a user profile that is used for targeting. Remember that these settings are tied to your account and are synchronized across all devices where you are signed in.
⚠️ Attention: Turning off personalization does not guarantee the complete disappearance of advertising in Google applications. You will continue to see ads, but they will be selected randomly, and not based on your interests.
Combating system advertising in manufacturers' shells
Owners of smartphone brands Xiaomi, Huawei, Samsung i Realme often encounter advertising built directly into system applications: “Explorer”, “Music”, “Downloads” or lock screen. Manufacturers thus subsidize the cost of iron. Fortunately, in most cases, these functions can be disabled manually in the depths of the settings.
Consider an example of the popular shell MIUI from Xiaomi. To remove advertising, you need to disable the service MSA (MIUI System Ads). Go to Settings → Passwords and security → Access to personal data. Find "msa" in the list and disable the switch. The system will try to dissuade you by asking you to wait 10 seconds - be patient and click “Recall.”
Next you need to go through each system application. In Explorer, go to Settings and turn off “Get recommendations.” In the Downloads app, tap the three dots in the corner, select Settings, and uncheck Show recommended content. Similar actions are required for the "Security" and "Music" applications.
Secret code for Xiaomi
On some Xiaomi models, entering a secret code in the "Phone" application helps: ##6485##. This opens a hidden battery menu, but in older firmware versions you could find additional logs and debug settings there, useful for diagnostics.
For devices Samsung advertising is less common, but may appear as “recommendations” on the home screen or in notifications. Turn off the Samsung Daily (or Google Discover) feature by swiping left on the home screen and going to Settings to remove the news feed. Also check the notification settings for Samsung system applications.
System advertising in Android shells is not disabled with one button, but requires sequential visits to the settings of each built-in application. Patience is the main tool here.
Installing advanced blockers and firewalls
If standard methods are not enough, specialized blocker applications come to the rescue. The leader in this niche is AdGuard. Unlike the version from Google Play, which has limited functionality due to the rules of the store, the full version, downloaded from the official website of the developer, creates a local VPN tunnel to filter all traffic.
The application works as a local one proxy server. All Internet traffic passes through it, where it is filtered by databases of well-known advertising domains. This allows you to remove ads even in applications that do not support system DNS filtering. However, it is worth considering that the constant operation of such a filter may slightly increase battery consumption.
For advanced users with root access, there are even more powerful tools, such as AdAway. This application modifies the system file hosts, redirecting requests to ad servers to nowhere (to address 127.0.0.1). This is the most reliable method, since it works at the lowest level of the system and does not require a constantly active connection or the creation of a VPN tunnel.
- 📲 AdGuard is the best solution for users without root access, has a user-friendly interface.
- 🔓 AdAway is an ideal choice for enthusiasts with an unlocked bootloader and Root access.
- 🛡️ Blokada —an open solution with flexible settings for filtering lists.
Remember that installing applications from unknown sources requires increased vigilance. Download blockers only from official developer sites to avoid fakes, which themselves can be a source of viruses.
Is it safe to use ad blocking applications?
Using proven open source applications or from well-known vendors (like AdGuard) is safe. They do not transfer your personal data to third parties, but only filter traffic. However, avoid dubious “boosters” and “cleaners” from unverified sources.
Does ad blocking affect the operation of sites?
Some sites may detect blockers and ask you to disable them to view content. In such cases, you can add the site to exceptions in the blocker settings. This will not affect the overall protection of the device.
Do you need root access to remove all advertising?
No, in 95% of cases it is enough to use private DNS and configure system applications. Rooting gives you more control, but opens up security risks and can void your device's warranty.
Why do ads appear again after a factory reset?
When you reset your device, all your settings, including DNS and app disables, return to factory settings. You will have to repeat the blocking setup procedure after turning on the phone for the first time.
