Removing ads on Android once and for all

The modern smartphone user encounters digital noise every day. Banners, pop-ups, and videos interrupt your reading, interfere with your gaming, and are just plain annoying. The problem is especially acute on devices running Android, where the openness of the system allows application developers to implement aggressive monetization models. Sometimes advertisements even appear on the desktop, covering the icons of important apps.

There are many ways to combat this phenomenon, from simple settings in the browser to deep modification of system files. However, not all methods are equally safe. Some require receipt root access, which can lead to loss of warranty, while others are available to any smartphone owner in a couple of minutes. In this material, we will analyze the most effective and legal methods of cleaning your device from intrusive content.

It is important to understand the nature of the appearance of advertising. Often the culprit is not the phone settings themselves, but specific applications that you installed recently. Free utilities, flashlights, QR code scanners and simple games often live by displaying ads. Our task is to find the source of the problem and neutralize it without disturbing the stability of the operating system.

Search and remove culprit applications

The first step in the fight for a clean screen is an audit of installed apps. Attackers often disguise malware as useful utilities. Such an application may not have an icon in the menu, but continues to run in the background, generating pop-ups on top of other apps. You need to carefully study the list of all installed software.

Go to the settings of your device and find the section Applications or Application Manager. Scroll to the very end of the list. Look for apps without a name or with a blank icon. Often viruses are hidden at the very bottom of the list or have names similar to system processes, for example System Update or Wi-Fi Service, but with a suspicious developer.

If you notice that advertising appears immediately after launching a specific game or utility, try removing it and checking the result. In some cases, the standard “Delete” button may be inactive. This means that the application has been granted device administrator rights. To fix this, go to Security → Device Administrators and uncheck the suspicious application.

⚠️ Attention: If the application is not removed in the standard way and continues to return after a reboot, it may have set itself as a system one. In this case, you may need to reset the settings to factory settings, but before that, be sure to save important data.

After removing suspicious apps, it is recommended to scan the phone with an antivirus. Dr.Web, Kaspersky and Malwarebyteshave proven themselves well. They are able to find remnants of malicious code that may have been stored in the system cache.

Configuring a private DNS to block ads

One ​​of the most elegant and effective ways to remove advertising at the system-wide level is to use the function Private DNS (Private DNS). This method does not require the installation of third-party applications and works on Android 9 and above. The essence of the method is to redirect all requests to advertising servers to “nowhere.”

To implement this method, you will need the address of a reliable DNS server that blocks trackers and advertising. One of the most popular and proven solutions is the service AdGuard DNS. Its address is easy to remember and enter into the smartphone settings. This method blocks ads not only in the browser, but also inside many free applications and games.

To activate the function, follow these steps:

• 📱 Open Settings your smartphone.
• 🌐 Go to the section Connections or Network and Internet.
• 🔒 Find the item Private DNS (may be in the “Advanced” subsection).
• ⚙️ Select mode DNS provider hostname.
• 📝 Enter the address in the field: dns.adguard.com.
• 💾 Click “Save.”

After saving the settings, the system will begin filtering traffic. You may notice a slight increase in loading time for some pages when you first launch it as your phone establishes a secure connection. However, in the long run, this saves traffic and battery by preventing the loading of heavy advertising banners.

It is worth noting that this method does not block advertising that is “hardwired” directly into the application content (for example, promotional materials on YouTube or native advertising on Instagram). For such cases, other solutions are required, but this method eliminates pop-ups in the browser and simple games almost completely.

Cleaning the browser and blocking trackers

The main source of advertising garbage for many users is web browsers. Standard Chrome or Samsung Internet often skip annoying banners if you don’t install additional extensions. Fortunately, mobile browsers have become much more functional in recent versions.

The easiest way is to change your browser to one that has built-in protection. Browser Brave or DuckDuckGo block trackers and ads by default. If you are used to the interface, you can install the extension, but this will require a version of the browser that supports addons, or the use of alternative assemblies, such as Firefox for Android. Activate the option Chrome, you can install the extension uBlock Origin, but this will require a browser version that supports addons, or the use of alternative builds such as Firefox for Android.

In the settings of any modern browser, you should pay attention to the “Privacy” item. Activate the option Do Not Track (Do Not Track). Although many sites ignore this request, it signals your intention to maintain privacy. Also regularly clear your cookies and cache, as they store the identifiers by which advertising networks recognize you when you visit again.

Browser	Built-in blocking	Support for extensions	Working speed
Brave	High	No (built-in Shield)	Very high
Firefox	Average	Yes (uBlock Origin)	Medium
DuckDuckGo	High	No	High
Chrome	Low	No (on Android)	High

For advanced users, it is possible to use local proxy servers. Applications like AdGuard (full version) create a local VPN tunnel on the device and filter all traffic passing through it according to specified rules. This gives maximum control, but may consume more battery resources.

Resetting the advertising identifier (AAID)

Google assigns a unique one to each device Advertising ID (Advertising ID). It is used to target advertising: systems analyze your interests and show ads that are more likely to interest you. While this does not eliminate the number of ads, it does confuse the algorithms and make ads less personalized and intrusive.

You can reset this ID at any time. This action is similar to changing your passport number for advertising networks: they stop linking your current activity to your previous browsing history. In addition, you can completely disable personalization, which will make advertising random and less relevant to your behavior.

The procedure is performed through the Google settings menu:

1. Open Settings phone.
2. Find the section Google (usually at the very bottom of the list of system settings).
3. Select item Advertising.
4. Click on the button Reset advertising identifier.
5. Confirm the action in the window that appears.

Here you will see a switch “Turn off ad personalization”. Activating it will not remove banners completely, but will prevent Google from using your data from Search, Maps, and YouTube to select ads. This is an important step to protect your digital privacy.

⚠️ Warning: After resetting your ID, you may notice that your ads become weirder or more irrelevant. This is a normal reaction of the system, which begins to collect data about you again from scratch.

Managing notifications from sites

Users often confuse system advertising and spam notifications from sites. You might have accidentally clicked “Allow” on a request from some news portal or horoscope site. Now this site has the right to send you push notifications with clickbait article titles directly in your notification shade.

To get rid of this, you don’t need to delete your browser. Just go to the notification settings of a specific site. In the browser Chrome this is done through the menu: click on the three dots → Settings → Notifications. Here you will see a list of all sites that have permission to send messages.

Check out the list carefully. If you see unfamiliar domains or sites that you don't want to see, click on them and select Delete or Block. This will instantly stop the flow of spam. A similar procedure is available in Yandex Browser and Opera in the content settings sections.

What what to do if the site is not removed from the list?

Sometimes malicious sites block access to their settings. In this case, go to Android general settings → Applications → Your browser → Storage → Clear data. This will reset all permissions, but will also delete saved passwords and browser history.

Be careful when browsing sites with adult content or pirated movies. This is where you most often find scripts that massively subscribe a device to notifications. The best protection is not to click the “Allow” button unless absolutely necessary.

Advanced methods: Hosts and root access

For users who are not afraid of complex settings and want total control, there is a method for editing the system file hosts. This file determines which domain names are translated to which IP addresses. By adding addresses of well-known advertising networks there and directing them to a local address 127.0.0.1, you will block the loading of advertising at the operating system level.

Without obtaining root access (superuser rights), it is impossible to edit the system hosts file. Obtaining root access (via Magisk or SuperSU) opens up great opportunities, but carries risks: you may lose your warranty, some banking applications will stop working, and if you make an error, your phone may turn into a “brick.”

If you are all If you decide to take this step, there are ready-made solutions that automate the process. Modules for Magisksuch as AdAwayautomatically update lists of advertising domains and apply them to the hosts file. This is one of the most powerful methods that works even without an Internet connection (advertising simply cannot load).

Let's compare the risks and benefits of different approaches to blocking:

Method	Complexity	Efficiency	Risks
Private DNS	Low	High	Minimal
Browser with blocker	Low	Medium (web only)	No
Reset ID	Low	Low (target only)	No
Root + AdAway	High	Maximum	High (loss of warranty)

Remember that developers of free applications live off advertising. By completely blocking it, you deprive them of their income. If an app is truly useful to you, consider purchasing the Pro version or subscribing. This will support developers and get rid of banners in a legal way.

Frequently asked questions (FAQ)

Why do ads appear even after deleting applications?

There is probably a hidden virus on your device or you have subscribed to notifications from sites. Check the list of device administrators and browser notification settings. Also try resetting your network settings or using Private DNS.

Will turning on an ad blocker slow down your phone?

Using Private DNS or light blockers has virtually no effect on performance. On the contrary, the phone can run faster since the processor does not need to handle heavy advertising scripts and animations. However, applications like the full-fledged AdGuard can consume more battery.

Is it safe to enter the address dns.adguard.com?

Yes, this is an official and verified server from AdGuard. It encrypts your DNS requests, which improves security when using open Wi-Fi networks. Your personal data is not transmitted through this server, it only filters requests to advertising domains.

Is it possible to remove advertising on YouTube without a Premium subscription?

Officially - no. Standard blockers are often powerless against advertising inside the YouTube video player, since it is loaded from the same domains as the video itself. This requires modified clients (for example, YouTube ReVanced), which are more difficult to install and carry certain security risks.

Does resetting the advertising ID delete your search history?

No, resetting the advertising ID only affects ad targeting. Your search, location, and app activity history is saved in your Google Account unless you clear it separately in the “My Activity” section.
