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) works differently from Chrome or Firefox.

If you use Samsung Internet, you can block sites through the browser's content blocker feature. If you use Chrome, you will need a separate blocking app. For parental controls that block sites across all browsers, you can use Samsung's built-in Kids Home or a third-party app like Google Family Link.

Key Takeaways

  • Samsung Internet has a content blocker that can restrict access to specific websites within that browser only.
  • Chrome does not have a native website blocker, so you will need to install a third-party app to block sites there.
  • Samsung Kids Home lets parents block websites across all apps and browsers on a child's phone.
  • Third-party blocking apps like Freedom, Cold Turkey, or AppBlock work across browsers but require you to grant them device administrator access.
  • DNS-level blockers like NextDNS block sites at the network level, which works on any browser but requires setup on your Wi-Fi router or phone's network settings.

Blocking websites in Samsung Internet

Open Samsung Internet and tap the three-line menu icon in the bottom right corner. Scroll down and tap Settings, then Privacy. Look for Content blocker and turn it on.

Once enabled, the content blocker will prevent ads and tracking scripts from loading on websites you visit. However, this is not the same as blocking an entire website — it blocks ad networks and trackers, not the site itself. If you want to block a specific website entirely within Samsung Internet, you will need to use a third-party app instead, since Samsung Internet does not have a manual blocklist feature.

Using Samsung Kids Home for parental controls

If you are setting up a phone for a child or want to restrict access across all browsers, Samsung Kids Home is built into most Samsung phones. Open Settings, search for Parental controls, and tap Samsung Kids. You will be asked to create a PIN that only you know.

Once set up, you can add a child's profile and restrict which apps they can use. In the Kids Home settings, you can also block specific websites by adding them to a blocklist. This restriction applies across all browsers on the phone, not just one. The child will see a message saying the site is blocked when they try to visit it.

Samsung Kids Home also lets you set screen time limits, restrict in-app purchases, and monitor app usage. The PIN you create is separate from your phone's lock screen PIN, so a child cannot bypass it by knowing your phone password.

Blocking websites with third-party apps

Apps like Freedom, Cold Turkey, AppBlock, and BlockSite let you block websites across all browsers. Download one from the Google Play Store and open it. You will typically need to grant it Device Administrator access, which prevents the app from being uninstalled or disabled without your permission.

To grant device administrator access, open Settings, search for Device administrators or Apps with special access, and toggle on the blocking app. Then return to the app and add the websites you want to block to its blocklist. Most of these apps let you set schedules (for example, block social media between 9 p.m. and 7 a.m.) and require a PIN to disable the blocker.

The downside is that these apps consume battery and memory, and some require a paid subscription for advanced features. Free versions usually offer basic blocking without scheduling or password protection.

Using DNS-level blocking across your network

A DNS blocker works at the network level, meaning it blocks websites on any browser or app that uses your Wi-Fi or mobile data. Services like NextDNS, Cloudflare for Families, and OpenDNS intercept domain name requests before they reach the website.

To use NextDNS on your Samsung phone, go to Settings > Connections > More connection settings > Private DNS. Enter the NextDNS server address (provided when you sign up). You can then log into your NextDNS account on a computer and add websites to your blocklist — they will be blocked on your phone automatically.

DNS blocking works across all browsers and apps, but it requires setup and some services charge a monthly fee for advanced features. It also does not work when you switch to mobile data unless you set up the DNS on your phone's network settings, which some carriers do not allow.

What to do if a website keeps loading despite blocking

If a website still loads after you have blocked it, check which browser you are using. If you blocked it in Samsung Internet but are using Chrome, the block will not apply. Make sure you have blocked the site in every browser your phone has.

If you are using a third-party app and the site still loads, the app may not have device administrator access. Go back to Settings > Device administrators and confirm the app is enabled. If it is, restart your phone and try again. Some apps require you to restart before changes take effect.

If you are using DNS blocking and a site still loads, your phone may be using a different DNS server. Check your phone's network settings to confirm the DNS address is correct, or try switching to a different DNS service.

Frequently Asked Questions

Can someone unblock a website if I block it?

If you use Samsung Kids Home or a third-party app with device administrator access, they cannot unblock a website without your PIN or password. If you only use Samsung Internet's content blocker, it can be turned off in settings without a password, so it is not tamper-proof.

Will blocking a website slow down my phone?

Samsung Internet's content blocker may actually speed up browsing by preventing ads from loading. Third-party blocking apps use a small amount of battery and memory, but the impact is usually not noticeable. DNS blocking has almost no impact on speed.

Can I block a website on mobile data, or only on Wi-Fi?

Samsung Internet and third-party app blockers work on both Wi-Fi and mobile data. DNS blocking works on Wi-Fi if you set it up in your router settings, but on mobile data it depends on whether your carrier allows custom DNS — many do not.

What is the difference between blocking ads and blocking a website?

Blocking ads (through Samsung Internet's content blocker) stops ad networks and trackers from loading, but you can still visit the website. Blocking a website prevents you from reaching it at all. They serve different purposes.

Can I block websites on someone else's Samsung phone?

Only if you set up parental controls through Samsung Kids Home or a third-party app before handing them the phone. If the phone is already set up, you cannot remotely block websites without their cooperation or access to their device.
