Advertising on mobile devices has long ceased to be just a way to monetize free services and has turned into an aggressive tool that reduces system performance and wastes traffic. Smartphone owners are faced with intrusive banners in the browser, pop-ups in games, and even system notifications from low-quality applications. Complete ad blocking on Android requires an integrated approach, since there is no single magic button for all cases.
In this article we will look at the most effective and safe ways to clear your device of visual noise. We'll cover low-tech methods that are suitable for most users, as well as more advanced configurations for those who want maximum control over network traffic. The effectiveness of each method varies depending on the version of the operating system and the model of your gadget. root access, which are suitable for most users, as well as more advanced configurations for those who want maximum control over network traffic. The effectiveness of each method varies depending on the version of the operating system and the model of your gadget.
System setting up private DNS
One of the simplest and most effective ways to remove most of the advertising traffic is to use the “Private DNS” function built into modern versions. Android starting from version 9. This method works at the system level and filters requests before they reach ad servers, which allows you to block banners in browsers and many applications without installing third-party software.
To activate, you need to go to the menu Settings → Network and Internet → Private DNS. In the window that opens, select the “DNS Provider Hostname” mode and enter the address of a reliable blocker, for example dns.adguard.com. After saving the settings, the system will begin to redirect all DNS requests through servers AdGuardthat automatically filter out domains known as sources of advertising and trackers.
This method has virtually no effect on the speed of the smartphone and does not require additional battery resources, since filtering occurs on the remote server side. However, it is worth considering that this method will not be able to block advertising that is loaded from the same domains as the main content of the site, or embedded advertising on popular social networks and video hosting sites, since they use HTTPS encryption.
⚠️ Attention: When entering the private DNS address, make sure that the domain is spelled correctly. An error in one letter can lead to a complete loss of Internet access on the device, since the smartphone will not be able to resolve any domain names.
If, after enabling private DNS, some sites no longer open, try temporarily disabling this function or changing your provider to the standard automatic mode to check the network's health.
Usage DNS filtering is an excellent first step for those who do not want to overload the device with unnecessary applications. This solution works globally for all connections, including mobile network and Wi-Fi, providing a basic level of protection against intrusive banners and malicious advertising.
Setting up a private DNS is the fastest way to block ads without installing additional apps, working at the level of the entire operating system.
Installation specialized blockers
If the built-in system tools are not enough, specialized blocker applications such as AdGuard, Blokada or DNS66come to the rescue. These apps create a local one on the device through which all traffic is passed, analyzing it in real time and filtering out advertising requests before sending them to the network. VPN tunnel on a device through which all traffic is passed, analyzing it in real time and filtering out advertising requests before sending them to the network.
Unlike system DNS, full-fledged applications offer flexible filtering settings. You can choose specific block lists, set exceptions for your favorite sites or apps, and block trackers and analytics counters that monitor your activity. Some of these solutions require installing a user certificate to be able to filter HTTPS traffic within applications.
The installation process is usually standard: download the APK file from the official website of the developer (since such applications are often limited in functionality on Google Play due to store policies), install it and provide the necessary permissions to create a VPN connection. Once launched, the application will start running in the background, and you will immediately notice faster page loading and the disappearance of banners.
- 🛡️ AdGuard - a powerful all-in-one tool with the ability to filter HTTPS, tracker blocking and parental controls.
- 🚀 Blokada 5 - a lightweight open source solution that focuses on speed and minimal resource consumption.
- 🔒 DNS66 - a simple tool that uses only DNS filtering without creating a full-fledged VPN tunnel, which saves battery.
It is important to understand that running such applications in the background can slightly increase battery consumption, although modern optimization algorithms reduce this effect to a minimum. Also, when using free versions of some blockers, you may encounter restrictions on the number of updated filters or connection speed.
Blocking ads in mobile browsers
A significant part of advertising is consumed through web browsers while surfing the Internet. Standard Google Chrome has built-in protection against intrusive advertising, but it is far from ideal and often misses many types of banners. For comfortable browsing, it is better to use specialized browsers or install extensions.
The optimal solution is to use browsers with a built-in blocking engine, such as Brave, DuckDuckGo or Firefox with an installed addon uBlock Origin. These browsers are initially configured to protect the user's privacy and automatically block mining scripts, trackers and advertising networks without requiring complex configuration on the user's part.
If you prefer to stay in the ecosystem Chromethen the options for expanding functionality are limited. The mobile version of the browser does not support installing classic extensions from the Chrome Web Store. In this case, you can try to activate experimental flags by going to chrome://flags and finding options related to security and advertising, but their effectiveness is extremely low.
⚠️ Attention: Browser interfaces and settings names may change with each update. If you do not find this option, check the official help from the developer or update the application to the latest version.
Using browser extensions or specialized browsers allows you to not only remove visual noise, but also significantly speed up page loading, since the browser does not need to download heavy advertising media files. This also saves mobile traffic, which is especially important when using limited tariff plans.
Why do ads sometimes still appear?
Some sites use methods to bypass blockers (Anti-Adblock), detecting the presence of a blocker and requiring it to be disabled in order to view the content. In such cases, temporarily disabling protection for a specific domain or using Anti-Circumvention filter lists helps.
Clearing notifications and pop-up windows
A frequent problem is not banners on sites, but intrusive push notifications from sites to which the user accidentally subscribed, or advertisements from installed applications that pop up on top of the desktop. Such notifications are often disguised as system messages or messages from instant messengers.
To get rid of spam in the notification curtain, you need to go to the notification settings of a specific browser or application. In Chrome this is done through the menu Settings → Site Settings → Notifications. Here you will see a list of all sites that are allowed to send notifications, and you can block suspicious domains with one click.
If ads pop up on top of other applications even when the browser is closed, most likely the culprit is some installed application with aggressive monetization. Often these are “flashlights”, “memory cleaners”, simple games or weather widgets. You need to carefully analyze the list of recently installed apps and remove those that cause suspicion.
To identify malware, you can use the “Battery Usage” function in the smartphone settings. Apps that display ads in the background often rank high on this list, even if you don't actively use them. Removing such software will instantly stop pop-up windows from appearing.
- 🔍 Check the section
Applicationsand sort them by installation time to find recent suspicious apps. - 🚫 Block notifications from displaying for all sites in the browser settings, if you do not use this function consciously.
- 🧹 Use the built-in security scanner Google Play Protect to scan your device for malware.
Advanced methods with root access
For users with rights root (superuser), system ad blocking capabilities are opened that are not available to ordinary users. Having root access allows you to modify the system file hosts, redirecting requests to ad servers to nowhere (to the local address 127.0.0.1) at the deepest level of the operating system.
The most popular tool in this category is the module AdAway. After granting superuser rights to the application, it automatically updates the lists of advertising domains and makes changes to the system hosts file. This method is the most effective, as it blocks ads before they even try to load, saving processor and battery resources.
In addition, root access allow you to use modules for Magiskthat can cut ad libraries directly from system applications or block ads inside other applications, emulating the lack of network connection only for advertising domains. This allows you to remove advertising even in places where regular VPN blockers are powerless.

echo "0.0.0.0 adserver.example.com" >> /system/etc/hosts
However, obtaining root access is fraught with risks: this can void the warranty on the device, make it impossible to use banking applications (due to the SafetyNet/Play Integrity protection being triggered) and, if done incorrectly, turn the smartphone into a “brick”. Therefore, this method is recommended only for experienced users.
⚠️ Attention: Modifying system files and obtaining root access is done at your own peril and risk. Always make a full backup copy of your data before starting any manipulations with the system partition.

Comparison of blocking methods
The choice of the optimal method depends on your goals, technical training and device model. There is no universal solution that would ideally suit everyone, so it is useful to compare the main approaches according to key parameters of efficiency and complexity of implementation.
Below is a table that will help you navigate and choose the appropriate option for your situation. Keep in mind that a combination of several methods (for example, private DNS + browser with blocker) often gives the best result.
| Method | Difficulty | Efficiency | Impact on battery | Root requirement |
|---|---|---|---|---|
| Private DNS | Low | Medium | Absent | No |
| Applications (VPN) | Medium | High | Low | No |
| Special. browsers | Low | High (in browser) | Absent | No |
| AdAway (Root) | High | Maximum | Absent | Yes |
Remember that completely blocking all advertising may negatively affect the operation of some free services that exist solely by displaying ads. In such cases, it is ethical to add the site to exceptions to support developers with content.
Combining system DNS for general filtering and a specialized browser for surfing provides the optimal balance between security, speed and ease of use.
Frequently asked questions (FAQ)
Will an ad blocker slow down my smartphone?
On the contrary, in most cases the device’s operation speeds up. Ad blocking prevents heavy graphics from loading and tracking scripts from running, reducing CPU load and saving internet bandwidth. Only in rare cases, low-quality blocking applications can consume a lot of resources.
Is it safe to use ad blocking applications?
Using proven open source applications such as AdGuard or Blokadadownloaded from official websites is absolutely safe. However, you should avoid dubious apps from unknown sources, which may themselves carry malicious code or collect your data.
Why are YouTube ads not blocked by these methods?
Advertising in the application YouTube is broadcast from the same domains as the video content over a secure HTTPS connection. Conventional DNS filters and VPN blockers cannot distinguish an advertising video stream from the main one without disrupting the operation of the application. Blocking YouTube ads requires modified clients or specific settings.
Does the blocker application need to be kept running all the time?
Yes, for methods that use a local VPN (for example, Blokada), the application must run in the background to intercept and filter traffic. System DNS operates continuously at the network settings level and does not require a running application. Browser blockers are active only while the browser itself is running.
