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-

Samsung Internet (Just Clear Cache)

It works for a time and then after some time Chrome stops working, but only over Wifi. Mobile data always works. I've had this problem for ages, also with the adblockers that use a local VPN, exact same thing. I did the async dns disable and clearing dns cache as in the first post. It works for a while and then Chrome just stops loading.
