Block Ads on Android 9.0+ (Without downloading any app)

[Aashish]

In android 9.0 pie and above we have an option to set Private DNS, this can be used to block ads on your phone.

STEP 1- Under Connection in Settings, scroll down and select More Connection Settings.

STEP 2- Select the Private DNS Option

STEP 3- Select Private DNS  provider hostname and enter the following in the text bar

For Adguard DNS: dns.adguard.com      

For Adguard DNS and removing adult content: dns-family.adguard.com

Additional STEPS for using this with Google  Chrome-

Since Google Chrome uses its own DNS resolver, we need to disable that for ad block to work. 

STEP 1-

• Launch Chrome app.
• Enter the URL “chrome://flags”, without quotes, into the address bar.
• You will see a new window with many flags.
• Search for “dns”.
• Set the “Async DNS” option to “Disabled” and close the tab.

STEP 2- You will also need to clear the prebuilt DNS cache.

• Enter “chrome://net-internals”, without quotes, into the address bar.
• Select the DNS tab, and tap on “Clear Cache”.
• Restart Chrome.

Confirmed Working on-

Google Chrome

Samsung Internet (Just Clear Cache)

No S8+ wont get android 10, you can try custom rom like Lineage but that too wont be perfect.

make your post smaller so it be easier to know what's that all about
and atleast write "try on your own risk" bcos who knows if that dns provider is collecting user data and selling them?
u know! people forget that they added dns and in future if something happens! they can't figure out what's the cause of this problem.

Bro the title says it all, also the post is small and only the images take up space.

In my S9plus some aweful pages are opening randomly and ads are showing unexpectedly. Can u tell me how to fix it? Pls reply

[Aashish]

You have to remove and 3rd party app you downloaded recently. When these things pop up press the recent bar to see what caused them.

Very helpful, also we can use BRAVE browser, based on Chromium (so it looks like Chrome) without Ads.
