How to disable advertising in Chrome on Android Samsung

Smartphone owners Samsung Galaxy often encounter intrusive advertising that interrupts reading articles or watching videos directly in the browser. Pop-up banners, redirects to dubious sites and auto-playing videos with sound - all this is not only annoying, but also reduces traffic and reduces the performance of the device. Fortunately, built-in tools Google Chrome and system settings Android allow you to effectively deal with this problem without installing third-party software.

In this article we will look in detail at how to set up pop-up blocking, disable notifications from sites and use secure DNS technology to filter traffic at the system level. These methods are suitable for most Samsung models, from budget series Galaxy A to flagship Galaxy S. You'll learn which settings are security-critical and which simply improve the user experience.

Before making changes, make sure your browser is updated to the latest version via Google Play Market. Outdated software may not support new content blocking standards. Let's start with the basic settings of the application itself.

Built-in pop-up blocker settings

The first and most obvious step is to activate the browser's built-in filter. Developers Chrome We have implemented a mechanism that blocks most aggressive ad formats by default, but sometimes you need to check it manually. Go to the settings menu by clicking on the three dots in the upper right corner and select Settings.

Next go to the Site settingssection. Here is the key switch Pop-ups and redirects. Make sure the slider is in the Locked position. If it is active, the browser will prevent new tabs from opening without your knowledge, which is the main source of annoying advertising.

Also in this section it is worth paying attention to the item Advertising. Google uses Better Ads Standards to filter content. When this option is enabled, the browser automatically hides ads that violate usability standards (for example, those that take up the entire screen or have a countdown). However, it is worth remembering that this does not block all advertising, but only the most annoying types.

⚠️ Attention: Complete blocking of all types of advertising may disrupt the work of some free news portals that exist solely by displaying banners. The site may ask you to disable the blocker to access the content.

Remember to periodically check the list of exceptions. Sometimes users accidentally add trusted sites to the white list, after which advertising on them begins to be displayed in full. Removing a site from the list of permissions will restore protection.

Blocking notifications from sites

Often users confuse advertising on a page with push notifications that arrive even when the browser is closed. This happens when you accidentally click the "Allow" button on a site's pop-up request. Such notifications may contain links to phishing resources or casinos.

To fix this, return to the menu Site settings and find the section Notifications. Here you will see a list of all the resources that you have given permission to send messages. Please study this list carefully. If you see unfamiliar domains or sites with suspicious names, revoke their access immediately.

• 🚫 Click on a specific site in the list and select the option Block or Delete.
• 🔒 For greater security, you can completely disable the notification slider at the top of the screen, prohibiting all sites from asking permission.
• 🧹 Regularly review this list, especially after visiting new resources.

On smartphones Samsung with a shell One UI Chrome notifications are integrated into the general notification shade. Blocking at the browser level will prevent them from appearing in the system. This is especially important for saving battery power, since constantly synchronizing background advertising processes consumes energy.

Using private DNS for global blocking

The most effective method that works not only in Chrome, but also in other applications on your Samsung is setting up a private DNS (Domain Name System). This method redirects requests to ad servers to "nowhere", preventing banners from loading before they even reach the screen.

You do not need root access for this. Go to the main Settings of your phone, then select the section Connections. Scroll down to Private DNS (or Private DNS). By default it is set to "Auto". You need to select the "DNS Provider Hostname" mode and enter a special address.

dns.adguard.com

After entering the address, click Save. Now all DNS queries of your device will go through the service filters AdGuard. This means that advertising will be blocked systematically. The method is characterized by high speed of operation and no need to install additional applications.

Parameter	Default value	Recommended value	Effect
DNS mode	Auto	Provider host name	Filtering activation
Host address	-	dns.adguard.com	Ad blocking
Security	Standard	DoT encryption	Protection against interception
Speed	Depends on the provider	High	Speed up page loading

It is worth noting that if you use public Wi-Fi networks that require authorization through a web page (captive portal), enabling private DNS may interfere with the connection. In such cases, you will have to temporarily disable this function in the settings Android.

Clearing data and resetting browser settings

Sometimes advertising appears due to accumulated site data, cookies or malicious scripts cached in the browser memory. If the previous methods did not help, it is worth performing a deep cleaning. This will return Chrome to the state "as after installation", but will save your bookmarks and passwords (if synchronization is enabled).

Go to your phone settings Applications, find it in the list Chrome and select Storage. Press the button Reset or Memory management -> Clear data. Confirm the action. After this, when you launch it for the first time, the browser will ask for basic settings again.

• 🗑️ All are deleted temporary files and image cache.
• 🍪 Clears cookies, which will log you out of most sites.
• 🛡️ Resets all site permissions, including pop-up blocker (will need to be turned on again).

This procedure is especially useful if you notice that that the browser began to work slowly or open strange pages on its own. On devices Samsung with a small amount of RAM, clearing the cache can also significantly speed up the interface.

⚠️ Attention: Before resetting your data, make sure you remember passwords for important accounts or that synchronization with your Google account is enabled, otherwise you may lose access to saved form data.

Extensions and third-party solutions

Unlike the desktop version, mobile Chrome on Android does not officially support installing extensions from the online store. This is a security limitation, but it makes fighting ads more difficult for advanced users. However, there are workarounds.

One ​​option is to use alternative Chromium-based browsers that support addons. For example, Kiwi Browser or Yandex Browser with the "Anti-shock" mode. You can install classic extensions like uBlock Originin them, which provide the maximum level of protection.

If you absolutely do not want to change your browser, you can use blocking applications that work through a local VPN. apps such as AdGuard (version from the developer's website, not from the Play Market) or Blokadacreate a local tunnel and filter traffic before it reaches the browser. This requires permission to create a VPN connection in the system. Samsung.

Why don’t extensions work in regular Chrome?

Google deliberately limited the functionality of the mobile version of the browser so as not to reduce performance on weak devices and control the ecosystem. Support for extensions may appear in the future, but has not yet been officially announced.

Using third-party blockers over a VPN may slightly increase battery consumption, since the filtering process is constantly running in the background. However, for most modern smartphones Galaxy this influence is invisible.

Security and infection prevention

Sometimes advertising is a symptom of a more serious problem - the presence of an advertising virus (adware) on the device. Such apps can disguise themselves as flashlights, QR code scanners, or wallpaper. They generate ads on top of all windows, even outside the browser.

If you see banners on the desktop or in the application menu, the standard Chrome settings will not help. In this case, you need to check the list of installed applications. Go to Settings -> Applications and carefully review the list. Look for apps without an icon, with a transparent name, or those that you did not install.

Removal of such malware is carried out in the standard way. If the "Delete" button is inactive, then the virus has acquired device administrator rights. To remove, go to Settings -> Biometrics and security -> Other security settings -> Device administrators and uncheck the box next to the suspicious application.

⚠️ Attention: Avoid downloading APK files from unverified forums and sites. In 90% of cases, advertising that cannot be disabled by settings gets onto the phone through such installation files. Regular use of the built-in antivirus will help prevent re-infection. On smartphones

Regular use of the built-in antivirus McAfee or Google Play Protect will help prevent re-infection. On smartphones Samsung protection is built into the system and works in the background, scanning new applications when installed.

Frequently asked questions (FAQ)

Why do ads appear even after pop-up blocking is turned on?

Most likely you allowed the site to send Push notifications. Advertising does not come through the browser, but as a system notification. Check the "Notifications" section in Chrome's sites settings and remove unnecessary permissions.

Does enabling private DNS affect Internet speed?

Usually the speed even increases, since DNS filters respond faster than the ISP's servers. However, in rare cases, if the connection is poor, there may be a slight delay when the page initially loads.

Can you block YouTube ads through Chrome settings?

No, Chrome's built-in tools cannot block video ads inside the YouTube player. This requires the use of specialized clients (for example, YouTube ReVanced) or blocking at the DNS level, which does not always work stably for video hosting.

Is it safe to enter dns.adguard.com into Samsung settings?

Yes, this is a safe and legal method. You simply change the Internet phone book address to a server that does not issue advertising network numbers. The data is encrypted using the DNS-over-TLS protocol.

What should you do if, after setting up DNS, some sites no longer open?

Some sites may block access from known DNS filters. Temporarily switch Private DNS mode to Disabled or Auto to test the resource. If the problem is confirmed, add the site to exceptions in the blocker application, if you use it.
