How to Block Porn on a Samsung Phone in 2026 (Galaxy S, A, M and Z)

On a Samsung Galaxy phone, open Settings, tap Connections, then More connection settings, then Private DNS. Choose Private DNS provider hostname, type family.cloudflare-dns.com and tap Save. Adult sites now fail to load in every browser and app. It takes two minutes and it is free.

The catch is that the same five taps switch it off. A Samsung phone also comes with a second browser and a second app store, Samsung Internet and the Galaxy Store, and both need closing off. This guide covers the free setup step by step, where it stops working, and how to get a block that holds when you are the one who wants it gone.

These steps are for One UI 6, 7 and 8, which covers Galaxy S, A, M and Z phones from the last few years. If a menu name on your phone is different, open Settings, tap the search icon and type the name of the setting. Samsung's search finds it.

Step 1: Set Private DNS to a Family Filter

Private DNS sends every web address lookup on the phone through a filter. When a lookup is for an adult site, the filter refuses to answer and the site does not load. It works in Chrome, Samsung Internet, Firefox and inside apps, on Wi-Fi and mobile data.

1. Open Settings.
2. Tap Connections.
3. Tap More connection settings.
4. Tap Private DNS.
5. Choose Private DNS provider hostname.
6. Type family.cloudflare-dns.com and tap Save.

Check it worked: open Samsung Internet or Chrome and try an adult site you know. It should fail with a connection error. If it still loads, a VPN is running on the phone, or the browser is set to use its own DNS. Step 3 fixes the second one.

Cloudflare's family filter is free and blocks malware too. family.adguard-dns.com works the same way if you prefer it.

Step 2: Lock SafeSearch On in Google

Private DNS blocks adult websites, but image search results can still show explicit pictures. Turn on SafeSearch so Google filters them out:

1. Open the Google app.
2. Tap your profile picture, then Settings.
3. Tap SafeSearch and choose Filter.

This setting is tied to your Google account, so it follows you to Chrome and Samsung Internet when you are signed in. It is one tap to turn back off, so treat it as a second layer, not the main one.

Step 3: Keep One Browser, and Check Its DNS

Every Samsung phone ships with two browsers: Samsung Internet and Chrome. Two browsers means two sets of settings to watch. Pick one and disable or uninstall the other.

• Samsung Internet has a switch called Block unwanted webpages. Despite the name, it stops pages that redirect you somewhere you did not ask to go. It is not an adult filter.
• Samsung Internet's Secret mode is a private window. It does not get around Private DNS, but it leaves no history, which is why people reach for it.
• Chrome has a setting called Use secure DNS, under Settings, Privacy and security. If it is set to a custom provider, Chrome can skip your filter. Leave it on the default.

Then delete any other browser you do not use.

Step 4: Turn On Auto Blocker

On One UI 6 and newer, Samsung's Auto Blocker stops apps being installed from anywhere except the official stores. That closes one easy route: downloading a browser or VPN as a file from a website.

1. Open Settings.
2. Tap Security and privacy.
3. Tap Auto Blocker and switch it on.

Like Private DNS, it is one switch away from being turned off.

Step 5: For a Child's Phone, Add Parental Controls

Samsung has two options for children.

Google Family Link is built into Samsung phones. Go to Settings, Digital Wellbeing and parental controls, Parental controls, and follow the steps. It filters mature sites in Chrome, keeps SafeSearch on and controls Play Store installs from a parent's phone. Two Samsung gaps to close in Family Link:

• Its web filter covers Chrome only, so block Samsung Internet as an app.
• Its Play Store rules do not cover Samsung's own Galaxy Store, so block that app too.

Samsung Kids is a separate child mode with its own home screen and a short list of approved apps. Open it from the quick settings panel. It is good for young children. Older ones can leave it with the parent's PIN, so the PIN has to stay secret.

Where the Free Setup Breaks

Everything above is set up by you, so it can be undone by you, usually in a few taps and with no passcode. Nobody is told when that happens.

A Block That Holds on Samsung: QuitPorn

QuitPorn is built for the case the free setup cannot handle: the person who set up the block is the same person who will try to remove it. It works on every Samsung Galaxy phone running a current version of Android, and it installs from Google Play.

• A timer, not a switch. You choose a lock from 1 day up to 365 days while you are thinking clearly. Until it ends, the filter stays on.
• No passcode at all. On Android there is no code to guess, write down or ask support for. The lock ends when your time is up. Changing the phone's date does not end it.
• Nobody can switch it off. It can't be deleted until the lock ends.
• Every browser, every app. Samsung Internet, Chrome, Firefox and the rest are all covered. A new VPN or a new browser does not get around it.
• Your own triggers. Add any app or site to the block list, and it stays blocked until the lock ends.

The same lock covers up to 5 devices from one account: Android, iPhone, iPad, Windows and Mac. A Galaxy Tab or a laptop with no block is the usual way around a phone that has one.

Set it up on your Samsung:

1. Sign up at quitporn.io and open the dashboard on your phone.
2. Install QuitPorn from Google Play. The setup page links straight to it.
3. Follow the guided setup, under 5 minutes with a video.
4. Choose your lock length and confirm.

Plans are $15 a month, $78 for six months, or $120 a year. If you have not started a lock yet, you can get a refund within 7 days. See the plans.
