Advertising on smartphones has become a real scourge for millions of Android users. It pops up in the most unexpected places: on top of the desktop, in the notification shade, and even in system applications that previously worked flawlessly. Intrusive banners not only irritate the visuals, but also consume precious battery power, as well as mobile traffic. For many gadget owners, the issue of digital hygiene becomes a top priority.
There are many sources of advertising content. These can be either legitimate but aggressive notifications from applications you have installed, or malware secretly installed along with useful utilities. Sometimes the problem lies in the settings of the Google Chrome or other browsers, which allow pop-up windows by default. Understanding the nature of advertising is the first step towards its complete elimination.
In this article we will look at all possible ways to combat digital waste. We'll look at system-level settings, using dedicated DNS servers, and manually cleaning applications. You no longer have to put up with the fact that your smartphone turned into an advertising stand. Let's return control of the device to your hands.
Analysis of sources of advertising spam
Before taking radical measures, it is necessary to identify the hero of the occasion. Most often, advertisements appear due to a recently installed application that you downloaded from a third-party source or even from the official store. Carefully analyze the list of apps added over the past week. Particular attention should be paid to utilities for “memory cleaning”, “flashlights” or simple games with low ratings.
Sometimes advertising modules are built directly into the code of a legal application. Developers monetize their work by showing you banners. However, there are parasitic applications that do not have an icon in the menu, but continue to run in the background. To find such hidden software, go to settings and carefully study the list of all installed apps. Look for strange names or empty icons.
⚠️ Attention: If advertising appears suddenly and covers the entire screen, immediately turn off the Internet (Wi-Fi and mobile data). This will prevent loading of new banners and will allow you to safely find the problematic application.
For accurate diagnostics, you can use the built-in tools of the system. The Digital Wellbeing or Battery sections often display app usage statistics. If some unknown app is actively running in the background, although you did not launch it, this is a sure sign of malicious activity. Removing suspicious software often solves the problem instantly.
Blocking ads through DNS settings
One of the most effective and safest ways to remove advertising at the entire level systems is to change the private DNS settings. This method does not require the installation of third-party applications and works on most modern versions of Android, starting with version 9. The essence of the method is to redirect requests to advertising servers to nowhere.
To activate this function, go to the settings menu of your device. The path may vary slightly depending on the manufacturer's shell, but usually it looks like this: Settings → Connection → Other connection settings → Private DNS. In the window that opens, select the "DNS provider host name" mode and enter the address of a special server that filters traffic.
dns.adguard.comAfter entering the address, save the settings. Now your smartphone will send all DNS requests through AdGuard servers, which automatically block known advertising domains. This solution works globally: advertising will disappear not only in the browser, but also inside most free applications and games. It is important to note that this method may not work in some applications that use encrypted connections to download content.
If, after changing the DNS, some sites or applications no longer open, try temporarily disabling this function or using an alternative address, for example, dns-family.adguard.com.
Using third-party DNS servers can also slightly speed up the loading of web pages by filtering out excess junk. However, it is worth remembering that you are entrusting your requests to a third party. In the case of AdGuard DNS the reputation of the service has been proven over the years, but you should always be careful when entering unknown addresses. You can return the standard settings in the same menu by selecting “Auto” or “Disabled.”
Configuring notifications in the Chrome browser
Often users confuse system advertising with notifications from sites to which they accidentally subscribed. When visiting various resources, we often click “Allow” on the pop-up window without reading the text. As a result, news portals and dubious services begin to send push notifications directly to the curtain of your phone. You can disable this stream through the settings of the browser itself.
Open the application Google Chrome and click on the three dots in the upper right corner. Go to Settings, then select Site Settings. Here you are interested in the "Notifications" section. In the list you will see all the resources to which you have given permission to send messages. Ruthlessly remove or block all strange domains.
- 🚫 Click on the suspicious site and select "Block" or "Delete".
- 🛡️ Turn off the "Notifications" switch at the top of the screen to prevent all sites from asking permission.
- 🧹 Clear your history and site data to reset all previous permissions.
In addition to notifications, you should disable pop-ups in your browser. In the same "Site Settings" menu, find the "Pop-ups and redirects" item and make sure the slider is in the "Blocked" position. This will prevent new tabs with advertising from opening when you click on links. Browser security Directly depends on your attentiveness to these parameters.
☑️ Checking browser security
Searching for and removing hidden viruses
If advertising appears on the desktop or when you unlock the screen, most likely a virus has settled in the system. Such malware is often disguised as system services or does not have a name in the list of applications. Detecting them using standard methods can be difficult, but possible. First of all, check the list of applications with administrator rights.
Go to the section Settings → Security → Device administrator applications. There shouldn't be anything extra here other than Find My Device or corporate profiles if you're using a work phone. If you see an unknown application with a check mark, immediately uncheck it and uninstall the app. Without removing administrator rights, the "Delete" button may be inactive.
| Virus sign | Action | Risk |
|---|---|---|
| Advertising on the desktop | Searching for an application without an icon | High |
| Rapid battery drain | Checking energy consumption statistics | Medium |
| Device heating at rest | Mining or hidden activity | High |
| Unknown SMS | Blocking paid subscriptions | Financial |
Another detection method is using safe mode. Press and hold the power button on the screen until you are prompted to reboot into safe mode. In this state, only system applications are launched. If the advertisement disappears, then third-party software is to blame. Uninstall recently installed apps one at a time, rebooting into normal mode after each uninstall until the problem goes away.
⚠️ Attention: Never download antivirus software from pop-up advertising windows. This is a classic trick of scammers. Use only proven solutions from the Google Play Store, such as Malwarebytes or Kaspersky.
Disable Google personalized advertising
Even if you remove pop-ups, Google continues to collect data about your interests to display targeted advertising in its services and partner applications. You can't completely disable advertising in the Google ecosystem, but you can reset your advertising ID and disable personalization. This will make advertising less intrusive and unrelated to your search history.
To do this, open your phone's settings and find the "Google" section. Go to the "Advertising" menu. Here you will see two important switches. The first one is “Remove Advertising ID”. This operation resets your accumulated interest profile. The second is “Turn off ad personalization.” Activating this item will prevent Google from using your data to select ads.
It is worth understanding that after disabling personalization, the number of advertisements will not decrease, only its content will change. You will see random ads instead of those that match your searches. However, this is an important step for protection Privacy. Repeat the ID reset process regularly to prevent algorithms from building an accurate user profile.
What is an Advertising ID?
An Advertising ID (AAID) is a unique number assigned to your device. It allows ad networks to track your activities across apps and build a profile of your interests. Resetting this number breaks the connection with previously accumulated data.
Use of specialized blockers
For advanced users for whom standard tools are not enough, there are powerful blocker applications. The leader in this niche is AdGuard. Unlike the DNS method, a full-fledged application can filter traffic more deeply, removing advertising on YouTube (in the browser) and blocking trackers in applications. However, for such apps to work, they often require the creation of a local VPN connection.
When installing such a blocker, the system will ask permission to create a VPN connection. Don’t be alarmed, the traffic does not go to third-party servers, filtering occurs locally on the device. In the application settings, you can select filtering levels: ad blocking, phishing protection, parental controls. Flexible configuration allows you to adapt the app to specific needs.
- 📱 Install the application from the official website of the developer, since versions in the Play Store are often cut down.
- ⚙️ Set up filters for specific applications if blocking interferes with the operation of the necessary services.
- 🔄 Regularly update filter databases to protect against new types of advertising.
There are alternatives, such as Blokada or DNS66. They work on a similar principle, but may have a different interface or set of functions. Some of them are open source, which increases confidence in data security. The choice of a specific tool depends on your technical skills and functional requirements.
Third-party blockers with a local VPN function are the most powerful weapon against advertising, but they can have a slight impact on connection speed and battery consumption.
Prevention and safe installation of applications
The best way to combat advertising is to prevent its appearance. A culture of digital hygiene begins with caution when installing new software. Always read reviews before downloading an app, especially if it's free. Pay attention to the permissions that the app requests: why does a flashlight need access to contacts or geolocation?
Avoid installing APK files from unverified sources. Hacked versions of paid games and apps often contain embedded adware or Trojans. The official Google Play store has built-in protection Google Play Protectthat scans applications for malicious code. Although it is not perfect, it is the first and important line of defense.
⚠️ Attention: Android interfaces and menu names may vary depending on the phone model and firmware version (MIUI, OneUI, ColorOS). If you cannot find the item you need, use the settings search.
Regularly audit installed applications. Remove anything you haven't used for more than a month. The fewer apps on the device, the fewer potential sources of advertising and vulnerabilities. Follow system updates, as new versions of Android introduce improved mechanisms for controlling the behavior of applications in the background.
Frequently asked questions (FAQ)
Why do advertisements appear even after deleting applications?
There may be an advertising identifier or cache of an old application left in the system. Try clearing your browser cache and resetting your advertising ID in Google settings. Also check to see if the application has any administrative rights left.
Is it safe to use DNS to block ads?
Yes, it is safe to use reliable DNS servers such as AdGuard DNS. This is a standard network setup that does not require root access and does not share your personal data with third parties other than request domain names.
Can an ad blocker affect the operation of banking applications?
In rare cases, aggressive filtering can block the operation of some scripts in banking applications or websites. If you notice any glitches, add the application to exceptions in your blocker settings or temporarily disable DNS.
How to remove ads on YouTube without a Premium subscription?
Officially, you can remove ads only through a subscription. Third-party clients (for example, YouTube ReVanced) allow this, but their installation requires complex manipulations and carries security risks. Using DNS blockers is often ineffective against video advertising inside the YouTube application.
What to do if the "Delete" button is grayed out for the application?
Most likely, the application has received device administrator rights. Go to Settings → Security → Administrator applications, uncheck the desired app, and then try to remove it again through the regular application menu.
