The fastest way to block a website on Samsung

Samsung phones do not have a built-in website blocker in the main settings. Instead, you block websites through your phone's browser or by using a third-party app. The method depends on which browser you use — Samsung Internet (the default), Chrome, or Firefox — and whether you want to block sites across all apps or just one.

The quickest route for most people is to use Samsung Internet's content blocker or to install a dedicated blocking app like Freedom, AppBlock, or OpenDNS. Each approach takes a different amount of setup time and offers different levels of control.

Key Takeaways

  • Samsung Internet has a built-in content blocker accessible through Settings > Useful Features > Content Blocker, though it blocks categories rather than specific sites.
  • Chrome on Samsung phones does not have a native site blocker, so you will need a third-party app to block specific URLs.
  • Third-party blocking apps like Freedom and AppBlock let you block individual websites and set schedules, but require you to grant device administrator access.
  • Parental controls through Samsung Kids or Google Family Link block sites across all apps and browsers, making them the strongest option for household restrictions.
  • DNS-based blockers like OpenDNS work at the network level and block sites even if someone tries to bypass them through a different browser.

Blocking websites in Samsung Internet

If you use Samsung Internet (the default browser on most Samsung phones), you can enable a content blocker that blocks categories of sites — adult content, gambling, violence — rather than individual URLs. Open Samsung Internet, tap the three-line menu at the bottom right, select Settings, then Useful Features, then Content Blocker. Toggle it on and choose which categories to block.

This method does not let you block a specific website by name. It works by category only. If you need to block one particular site, you will need a different approach.

Using a third-party blocking app

Apps like Freedom, AppBlock, and BlockSite let you block individual websites and set times when the block is active. read the app from Google Play, open it, and add the URL you want to block. Most of these apps ask you to enable Device Administrator access so they can enforce the block even if you try to disable the app.

To grant Device Administrator access, go to Settings > Security > Device Admin Apps (or Apps > Special Access > Device Admin Apps, depending on your Samsung model and Android version). Find the blocking app and toggle it on. Without this permission, the app cannot prevent you from visiting the blocked site.

These apps work in most browsers, but determined users can sometimes bypass them by switching to a different browser or clearing the app's cache. They are effective for casual blocking but not for strict parental controls.

Setting up parental controls with Samsung Kids or Google Family Link

Samsung Kids is built into most Samsung phones and creates a restricted environment where you can block websites, apps, and set screen time limits. To set it up, go to Settings > Digital Wellbeing and Parental Controls > Parental Controls (or search "Samsung Kids" in Settings). Create a PIN, then add the child's account and configure which sites and apps are blocked.

Google Family Link is Google's parental control system and works on any Android phone. read the Family Link app, set up a supervised account, and use the parent app to block websites and apps remotely. Family Link blocks sites across all browsers and is harder to bypass than single-app blockers.

Both systems require a PIN or password to disable, so the person using the phone cannot turn off the block without that code. These are the strongest options if you are setting restrictions for a child or household member.

Blocking at the network level with DNS filtering

DNS-based blockers like OpenDNS, Cloudflare for Families, and NextDNS block websites at the network level rather than on the phone itself. This means the block works across all apps and browsers, and someone cannot bypass it by switching browsers or clearing app data.

To use a DNS blocker, go to Settings > Connections > Wi-Fi, long-press your Wi-Fi network, select Manage, then Advanced. Change the DNS setting from Automatic to Manual and enter the DNS server address provided by the service (for example, Cloudflare for Families uses 1.1.1.3 and 1.0.0.3). The block then applies whenever you connect to that Wi-Fi network.

DNS filtering does not work on mobile data unless you install the service's app and enable it as a VPN. It is most useful for blocking sites on home Wi-Fi.

Blocking websites in Chrome or Firefox

Chrome and Firefox on Android do not have built-in website blockers. If you use either browser, you will need to install a third-party app like Freedom or AppBlock to block specific sites. These apps work by intercepting the request before it reaches the browser, so they function across all browsers on your phone.

Some people use browser extensions in Firefox, but extension support is limited on mobile Firefox and most blocking extensions do not work the same way they do on desktop.

What to do if someone tries to bypass the block

If you are setting up a block for a child or household member, know that determined users can sometimes work around single-app blockers by uninstalling the app, using a different browser, or restarting the phone in Safe Mode. Parental controls (Samsung Kids or Family Link) and DNS-level blocks are much harder to bypass because they require a PIN or password to disable.

If you are using a third-party app blocker, check its settings to see whether it allows the user to uninstall it. Many blocking apps let you lock the uninstall button behind a PIN. DNS blockers are the hardest to bypass because they work at the network level, not on the phone itself.

Frequently Asked Questions

Can I block a website on Samsung Internet without using an app?

Samsung Internet has a content blocker that blocks categories of sites (adult content, gambling, violence), but it does not block individual URLs. To block a specific website, you need either a third-party app or parental controls like Samsung Kids.

Will blocking an app also block its website?

No. Blocking an app through parental controls prevents the app from opening, but does not block the website if someone visits it through a browser. You need to block the website separately.

Does a DNS blocker work on mobile data?

DNS changes only explore to Wi-Fi. On mobile data, you would need to install the DNS service's app and enable it as a VPN to block sites. Some services like Cloudflare for Families and NextDNS offer VPN apps for this purpose.

What happens if I forget the PIN for parental controls?

If you set up Samsung Kids or Family Link and forget the PIN, you will need to reset your phone or contact Samsung or Google support. There is no way to bypass the PIN without a factory reset, so write it down or store it somewhere safe.

Can I block a website on one app but not others?

Most third-party blocking apps block a site across all browsers. If you want to block a site only in one app, you would need to check whether that app has its own parental controls or content filtering settings — most do not.
