Mobile advertising has become an integral part of the user experience, often turning into an intrusive element that blocks content and irritates the eye. Developers of free applications are forced to monetize their products, but aggressive banners and pop-ups seriously reduce the usability of the device. Fortunately, the operating system Android provides flexible tools for filtering network traffic, allowing you to effectively deal with unwanted content without the need to obtain root access.
There are several approaches to solving this problem: from changing system DNS settings to using specialized software and the command line. Some methods require minimal effort and work out of the box, while others involve deeper intervention into the system. The choice of a specific method depends on your technical background and the model of smartphone you are using.
In this guide, we will look at the most effective and safe methods for blocking ads. You'll learn how to set up private DNS, what apps to install to filter traffic, and how to use USB debugging to specifically disable ads in system components. These steps will help you regain control of your device and make its use more comfortable.
Using the Private DNS (Private DNS) function
The easiest and most effective way to remove advertising in most applications is to use the built-in function Private DNS (Private DNS). This technology allows all of your device's DNS requests to be redirected through a secure server that automatically blocks domains known to be advertising sources. You do not need to install third-party software, just change one setting in the system.
To activate this function, go to menu Settings → Connection → Other connection settings. In some interfaces the path may be different, for example Settings → Network and Internet → Private DNS. Select the option DNS provider hostname and enter the address of a reliable blocker. The most popular and stable solution is the service from AdGuard.
Enter the following line in the input field:
dns.adguard.comAfter saving the setting, the system will begin filtering traffic at the domain name level. This means that requests to ad servers simply will not be fulfilled, and instead of banners you will see empty space or a stub. The method works globally for all applications that use standard connection protocols and has virtually no effect on the Internet speed.
⚠️ Attention: If, after enabling this function, some applications stop downloading content or display a network error, try temporarily disabling Private DNS. Some services may conflict with blockers at the DNS level.
Use the address dns.adguard.com - this is a free and time-tested server that does not require registration and works stably on most versions of Android 9 and higher.
Installing local blockers and filtering traffic
If the built-in system tools are not enough, Specialized blocking applications come to the rescue. They create a local one on the device through which all traffic is passed before it is sent to the Internet. Inside this tunnel there is a powerful filter that cuts out advertising scripts, trackers and miners. VPN tunnel on a device through which all traffic is passed before it is sent to the Internet. Inside this tunnel there is a powerful filter that cuts out advertising scripts, trackers and miners.
One of the most popular solutions is the application AdGuard. It offers advanced capabilities over system DNS, allowing you to configure rules for specific sites and applications. The app is able to filter HTTPS traffic, which makes it effective even against complex advertising built directly into the application body.
Another powerful tool is Blokada. It is an open source application that regularly updates its block lists. It works on the principle of a domain blacklist: if the ad server address is in the database, the connection to it is blocked. The application is lightweight, does not require root access and has an intuitive interface.
- 🛡️ AdGuard: Full control over filters, anti-phishing protection and parental controls.
- 🚫 Blokada: Open source, minimalistic design and low battery consumption.
- ⚙️ DNS66: Lightweight solution that works solely based on host lists without complex filtering content.
When installing such apps, the system will ask for permission to create a VPN connection. This is a standard procedure required to intercept traffic. It is important to understand that with an active blocker, you will not be able to use other VPN services at the same time, since Android only supports one active VPN profile.
Disabling personalized advertising in Google settings
Although this method will not remove advertising completely, it will significantly reduce its intrusiveness and prevent the collection of data about your interests. Google allows users to limit the use of their data for targeted advertising. This makes advertisements less relevant, but more privacy-friendly. To change these settings, open the app on your smartphone and find the section. Inside the menu, select
To change these settings, open the application Settings on your smartphone and find the section Google. Inside the menu, select Advertising. Here you will see the option Remove advertising ID or Opt out of ad personalization. Enabling this switch will reset your unique ID, which ad networks use to track your behavior.
It is also recommended to check your settings internally specific browser or application store. For example, in Google Play Market you can go to settings and turn off interest-based ad personalization. This action will not hide the banners, but will stop analyzing your search queries and browsing history to select advertising content.
| Parameter | Description of action | Impact on advertising |
|---|---|---|
| Reset ID | Removing the current advertising identifier | Advertisers will start collecting data about you again |
| Refusal of personalization | Prohibition of using interests for targeting | Showing random or contextual advertising |
| Deleting history | Clearing data on actions in Google services | Reduces the accuracy of selection of advertising offers |
Regularly resetting the advertising identifier is a good hygienic practice for maintaining digital privacy. Do this once every few months to make it difficult for marketing algorithms to build your digital profile.
Ad blocking via USB debugging (ADB)
For advanced users who want to achieve maximum results without installing unnecessary applications, there is a method of using tools ADB (Android Debug Bridge). This method allows you to send commands directly to the system, disabling system components responsible for displaying advertising, or blocking access to known advertising domains through the hosts file.
Before you begin, you must activate developer mode. Go to Settings → About phone and quickly click 7 times on the item Build number. After the message about enabling developer mode appears, go to the new menu For developers and activate the switch Debugging USB.
Connect your smartphone to your computer with a cable. On the computer where ADB is installed, enter the command to test the connection:
adb devicesA request for debugging permission will appear on the phone screen - confirm it. Now you can use commands to block. One effective method is to set a global setting that prevents data collection for advertising, although a complete ban often requires modification of system files, which is impossible without root. However, you can disable specific Google services that are responsible for advertising.
Command to disable the Google advertising service
adb shell pm disable-user --user 0 com.google.android.gms.ads
Be careful when entering commands. Disabling critical system services may result in device instability or loss of functionality of some applications. Always check the name of the package before disabling it.
⚠️ Attention: Interfaces and names of system processes may differ depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS). Before running commands through ADB, check the documentation for your specific model.
The ADB method gives maximum control, but requires a PC and basic command line knowledge. An error in the command can lead to a software failure.
Configuring browsers with a built-in blocker
A significant part of advertising is displayed while surfing the Internet. Using a standard browser often means agreeing to display many banners. The solution is to install web browsers with built-in security mechanisms or configure extensions.
The browser Brave is positioned as a private solution “out of the box”. It automatically blocks trackers, pop-ups and video ads without the need for additional configuration. The browser engine is based on Chromium, so it supports all extensions from the Chrome store if you install it manually or through third-party stores.
If you prefer Firefox for Androidyou have the option of installing full extensions. The most effective addon is uBlock Origin. It consumes few resources and has a huge database of filters. To add it, open the browser menu, select “Add-ons” and find the required plugin in the list of recommended ones.
- 🦁 Brave: Built-in protection, high page loading speed, support for crypto functions.
- 🦊 Firefox + uBlock: Flexible filter settings, script support, open source code.
- 👁️ DuckDuckGo: Focus on privacy, automatic encryption of connections, assessment of site privacy.
There is also a browser Opera with a built-in free VPN and ad blocker. In its settings, you can activate the function of blocking pop-ups and trackers. This is convenient for users who need everything in one application without unnecessary configuration.
Specifics of blocking in games and system applications
The gaming industry has its own characteristics of monetization. Advertising in games is often divided into two types: in-game banners and rewarded videos. Complete blocking of video advertising, for which they give in-game currency, can disrupt the game's economy or lead to account blocking by the developer.
System applications from smartphone manufacturers (for example, Xiaomi, Samsung) may also contain advertising in their utilities: memory cleaner, themes, music player. In such cases, blocking via DNS may not be sufficient, since advertising is loaded from the manufacturer’s internal servers.
For devices Xiaomi (MIUI) there is a separate procedure for disabling advertising in system applications through the “Receiving recommendations” menu. You need to go into the settings of each system application and find this switch. This is a manual but effective way to clear the interface of debris.
☑️ Checking system advertising
Remember that aggressively blocking all traffic in online games may result in connection errors or inability to load levels. Test the settings gradually, observing the behavior of the application.
Frequently asked questions (FAQ)
Will enabling Private DNS slow down the Internet?
In most cases, the speed will not change or even increase due to the absence of loading advertising content. However, if the selected DNS server is geographically far from you, the response time (ping) when opening new sites may increase slightly.
Do these methods block advertising on YouTube?
Standard DNS blockers and most applications cannot remove advertising inside the official YouTube application, since the video stream and advertising are transmitted from the same domains. To block ads on YouTube, you need specialized clients (for example, YouTube ReVanced) or viewing through a browser with the uBlock Origin extension.
Is it safe to use applications like AdGuard?
Yes, if you download them from official developer sites or from trusted application stores (Google Play, F-Droid). These apps work locally on your device and do not transfer your personal data to third parties, but only filter incoming traffic.
What to do if an application stops working after being blocked?
Some applications (especially banking or government services) may block work when they detect an active local VPN or changed DNS. In this case, add the problematic application to the list of exceptions in the settings of your blocker or temporarily disable Private DNS.
