OpenDNS filtering not working on Android but works with DNS changer apps?

[georgekolasa1]

So I've been able to get OpenDNS filtering to work with DNS changer apps and the like on android. 

But I'd really like to get it to work without the app and just by following these android setup instructions I already followed and tried many times without avail: https://support.opendns.com/hc/en-us/articles/228009007-Android-Configuration-instructions-for-OpenDNS 

It doesn't work on either Firefox nor Chrome when done the traditional way. I've tried:

-resetting the router

-clearing browser cache

-re-entering the OpenDNS servers

-re-starting phone

But it still doesn't work. Any ideas on how to fix this?

Android is a bit resistent with such configuration changes, especially if you also have IPv6 connectivity.  In fact, a DNS changer app is the better way to use a 3rd party DNS service of your choice like OpenDNS, especially if you connect in different networks including mobile ones.

How did you check that you don't use OpenDNS on the Android device?  Visit http://welcome.opendns.com/ on it to verify it.  If you're not using OpenDNS, you could visit http://dnsleak.com/ to perform the test showing what DNS services you're actually using which may give you some clue.

Do you know that this feature is available only in networks you own, not for your devices in other networks?
