Advertising banners that suddenly pop up on top of the desktop or inside system applications can turn using a smartphone into real torture. They not only block useful content, but also significantly slow down the device, using up battery power and mobile traffic. Users often encounter the fact that even after closing applications push notifications continue to appear, forcing them to look for an urgent solution to the problem. In this article, we will look in detail at how to remove ads on Android, using both the built-in functions of the system and specialized software.
There are many reasons for the appearance of annoying ads: from legitimate advertising in free versions of games to malware secretly installed along with useful utilities. Understanding the source of the problem is already half the battle in the fight against digital waste. We will look at methods from simple browser settings to deep system cleaning that will help restore your gadget to its former speed and clean interface.
Diagnostics of the source of advertising spam
Before taking active blocking actions, you need to determine exactly which application generates pop-up windows. Often the culprit is a recently installed flashlight, QR code scanner, or memory "optimizer" that requires unnecessary permissions. To identify the offender, open the recent applications menu immediately after the banner appears. app namedisplayed in this list will indicate the source of the problem.
If the banner appears spontaneously on the desktop, it is worth checking the list of installed applications for the presence of suspicious icons without a name or with a transparent icon. Such apps are often disguised as system services. Go to Settings → Applications → All applications and carefully study the list, paying attention to installation dates and access rights. Removing suspicious software often solves the problem instantly.
⚠️ Attention: If you cannot remove the application and the “Delete” button is inactive, the malicious app may have acquired device administrator rights. In this case, first revoke the rights in the security menu, and only then uninstall.
Another sign of infection is rapid battery drain and heating of the case during idle mode. Advertising modules constantly run in the background, downloading content and sending data about your activity. Use built-in battery monitoring to see which app is consuming the most power in the background, even if you haven't used it. This is an indirect but sure way to find a hidden spy.
Blocking ads by setting up DNS (Private DNS)
One of the most effective and safest methods, which does not require installing third-party software, is to use the function Private DNS (Private DNS), available starting from version Android 9. This method redirects requests to advertising servers to nowhere, blocking the loading of banners at the level of the entire system, including browsers and many applications. To configure, go to Settings → Connections → Other connection settings (the path may differ depending on the shell).
In the DNS settings menu, select the "DNS provider host name" mode and enter the address of a reliable blocker. The most popular and stable solution is the service from AdGuard. In the input field you must enter the following address:
dns.adguard.comAfter saving the settings, the system will begin to filter traffic, cutting off requests to known advertising networks. You will notice that the empty spaces where the banners used to be will remain empty, and the pages in the browser will begin to load faster. This method works globally and does not require any application to be constantly active in the background, which saves processor resources.
If, after enabling Private DNS, some applications stop loading content or pictures, try temporarily disabling this feature. Some services may be blocked by mistake, although this rarely happens.
It is worth noting that this method does not block advertising within Google or YouTube applications, since they are loaded from the same domains as the main content. However, for the rest of the Internet and most free utilities, this solution is the gold standard. If you have an older version of Android that does not have a built-in Private DNS setting, you will have to use third-party clients.
Managing notifications and system permissions
Often, what users mistake for viral advertising are actually legal, but overly aggressive push notifications from sites that you accidentally subscribed to in the browser. To stop this flow, you need to go to your browser settings (Chrome, Yandex, etc.) and find the “Notifications” section. There you will see a list of sites that have the right to send you messages.
- 🚫 Disable the switches next to all suspicious or unfamiliar domains.
- 🧹 Completely remove sites with unclear names or icons from the list.
- 🔒 Prevent all new sites from asking for permission to show notifications by default.
- ⚙️ Check your pop-up settings in the "Privacy" section of your browser.
In addition to browser notifications, it's worth checking the permissions of the apps themselves. Go to Settings → Applications, select a specific app and click "Notifications". Here you can flexibly configure exactly what types of messages the application can send, or disable them completely. For games and utilities that are not instant messengers, a complete ban on notifications is usually recommended.
Pay special attention to applications that have the “On top of other windows” permission. This feature allows the app to display content on top of any other interface, which is often used by adware creators. Find this item in the advanced application settings and revoke the right from all apps that do not need it for their main function (for example, instant messengers need it, but a calculator does not).
Using specialized ad blockers
If the built-in system tools are not enough, specialized blocking applications come to the rescue. The leader in this niche is AdGuard, which works locally on the device, creating a local VPN tunnel to filter traffic. Unlike the DNS method, such applications are able to cut out advertising blocks directly from the web page code, making website browsing as comfortable as possible.
Installing such apps requires care. Once downloaded and launched, you will be prompted to activate your local VPN. This does not mean that your traffic goes to a third-party server; all filtering happens inside your phone. In the blocker settings, you can select the level of protection, add your own filters and create a white list for trusted sites that you want to support.
| Application name | Type of work | Presence of Root | Efficiency |
|---|---|---|---|
| AdGuard | Local VPN / Filters | Not required | High |
| Blokada 5 | DNS + Hosts file | Not required | Medium/High |
| AdAway | Modification of hosts | Required (Root) | Maximum |
| DNS66 | Local DNS | Not required | Average |
The application AdAway deserves special mention, but is required for its operation root access. It edits the system hosts file, redirecting advertising domains to a local address. This is the most reliable method with minimal resource consumption, but it is only suitable for advanced users who are ready to unlock the bootloader and gain full access to the system.
⚠️ Attention: Application interfaces and available functions may vary depending on the version of Android and the specific smartphone model. Always check the names of menu items with the current documentation of your device.
Why can blockers slow down the Internet?
When you enable a local VPN to filter traffic, a small overhead (delay) is created for the processing of each data packet. On modern powerful smartphones this is not noticeable, but on older devices the speed can decrease by 5-10%.
Cleaning from viruses and malware
In cases where advertising appears even after blocking notifications and setting up DNS, there is a high probability of a full-fledged virus trojan in the system. Such apps are often disguised as harmless utilities and have self-healing mechanisms. To combat them, standard removal may not be enough.
It is recommended to scan the device using reputable antivirus solutions such as Dr.Web Light or Kaspersky Internet Security. Run a full system scan, paying special attention to quarantine. If your antivirus finds a threat, follow the instructions to remove it. In some cases, you may need to reboot into safe mode to delete a file that is blocked by the system.
☑️ Algorithm for treating an infected smartphone
If the malware is not removed using standard methods, you may have to resort to extreme measures - resetting the settings to factory settings. Before this procedure, be sure to save important contacts and photos, as all data will be deleted. After resetting, do not restore applications from a backup copy immediately, but install them manually so as not to return the virus back.
Advanced methods: ADB and disabling system advertising
For users who are not afraid to work with a computer, there is a powerful debugging tool ADB (Android Debug Bridge). It allows you to disable system components and pre-installed applications that cannot be removed through the normal interface. This is especially true for smartphones from Chinese brands, where system advertising is built into the shell.
To work, you will need to enable “USB Debugging” in the developer menu and connect the phone to the PC. You can use the command line to send commands to disable packages. For example, to disable advertising on a Xiaomi system, you can use the command:
adb shell pm disable-user --user 0 com.miui.msa.globalUsing ADB requires caution: disabling critical system processes can lead to unstable operation of the device or a “bootloop” (cyclic reboot). Always check the package name before disabling it. There are ready-made scripts and GUI utilities (for example, Universal Android Debloater) that simplify this process and tell you which packages are safe to disable.
Using ADB is the most powerful way to customize Android, allowing you to remove ads at the system level, but it requires a PC and care when entering commands.
Frequently asked questions (FAQ)
Is it safe to use free ad blockers?
Yes, using proven open source blockers or from well-known vendors (like AdGuard) is safe. They do not steal data, but only filter traffic. However, avoid downloading dubious “anti-virus” applications from unverified sources, as they themselves may contain advertising.
Why do advertisements appear even in airplane mode?
If advertisements appear without the Internet, this is 100% a sign of a malicious application installed on the phone, or cached advertising. It is urgent to check the list of applications and conduct a full anti-virus scan, since DNS blocking will not help here.
Does ad blocking affect the operation of sites?
Some sites may detect the presence of a blocker and ask you to disable it to view content. In rare cases, the site's layout may "go wrong" if the advertising unit occupied an important place in the page structure. This is usually solved by adding the site to the blocker's exclusions.
Are root access needed to effectively combat advertising?
For most users, Root is not needed. The Private DNS method and applications like AdGuard block up to 90% of ads. root access make it possible to remove system advertising forever and use AdAway, but this complicates the use of banking applications and reduces the overall security of the system.
How to remove advertising in specific games without purchasing Premium?
Removing advertising inside free games is the most difficult, since it is often built into the application code. The DNS method helps partially, but the best way is to disable the Internet for a specific game in the traffic consumption settings if the game does not require an online connection for gameplay.
