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)

1. You won't be able to view most of the video ads in apps and games, so if you want to get free coins for watching the video ads in some app/game, you'll probably have to turn off the private DNS.

2. I have trouble connecting to public wifi hotspots. When you connect to such hotspot, it should open an authorization page, where you need to enter the phone number and wait for an SMS with the code to connect (at least in my country so). Adguard blocks access to these pages and I have to disable it so they load up.

3. Some web-sites are not working properly (don't load, don't fully load or load crooked and so on) . I have met problems very rarely, but still met.
