I didn't see this readily available and had posted it on the Galaxy S5 forums, but it works on most devices. This will work on both wifi and mobile data.
--First step would be to install Adblock Plus APK. I got mine from: https://adblockplus.org/en/android-install
--After installing, run the app once and activate filtering. It should now be blocking all ads on wifi only. To enable adblock on mobile data you need to add a proxy to your APN.
--Go to your APN settings: system settings>network connections>more networks>mobile networks>access point names (could be different depending on phone and android version). What you need to do now is go to you default APN and copy down all the settings. We only do this because you cannot edit the original APN it seems (If you can edit your default APN, you can add the proxy to the existing APN). Now create a new APN and enter in the copied settings. The only additional settings you add to add to the new APN is:
---Proxy: localhost
---Port: 2020
Make sure you set the new APN you created as active and adblocking should be working! I have done this on my T-mobile S5. Hopefully some of you will find this useful.
