Low Level Settings guide

Inside Adguard for Android 'Advanced settings' tab there is a 'Low Level Settings' button. Once you tap it, you will see a big list of various settings, many of which might be confusing to an average user.

WARNING! Changing any of these settings without knowledge of what that particular setting does may lead to undesirable consequences! Ask our support for advice if you are in doubt about this or that setting.

Below we will try to describe what some of the most important and often-used low level settings are for.

pref.net.exclusions

If you tap this button, you will find a list, and each entry of this list is a package name of some application. The whole reason of this section is to whitelist any app on a level deeper than you would get using Adguard Firewall. Traffic of apps from pref.net.exclusions list will not even go through Adguard, so it can't be modified in any way by definition.

To add an app to this list simply add a new entry with app's package name. For apps from Google Play it is really easy to determine the package name. Just open the apps page in GooglePlay and look at the address bar. The part after 'id=' is exactly what you need to look for. For example, for YouTube app the whole link would be

https://play.google.com/store/apps/details?id=com.google.android.youtube

with com.google.android.youtube being the package name.

HTTPS filtering preferences

We united several settings under this category: pref.https.apps.exclusions, pref.https.domains.blacklist and pref.https.domains.whitelist. They are essentially the same settings you can find in HTTPs filtering settings tab. You can find more information about them in our blog:

pref.vpn.ipv6.bypass

Nowadays, more and more often SMS and MMS are sent via network, and when they are, non-standard IPv6 network is often used. When we try to filter this traffic, it is not extremely unusual that we interfere with sending and even receiving MMS. If you suspect this is your case, we recommend checking the pref.vpn.ipv6.bypass checkbox or adding the app responsible for MMS managing to pref.net.exclusions.
