**(28) Why is Google connectivity services allowed internet access by default?**
The Google connectivity services system application checks if the current network is really connected to the internet.
This is probably done by briefly connecting to some Google server.
This is probably accomplished by briefly connecting to some Google server.
If this is not the case, there will be an '!' in the Wi-Fi or mobile icon in the system status bar.
Recent Android versions seem not to switch connectivity from mobile to Wi-Fi when the Wi-Fi network is not really connected,
even though there is a connection to the Wi-Fi network (or the other way around). On Android 6.0 and later you might get a notification asking you if you want to keep this connection on or not.
To prevent a bad user experience there is a predefined rule to default allow the Google connectivity services.
To prevent a bad user experience, NetGuard includes a predefined rule to default allow the Google connectivity services.
You can find all predefined rules [here](https://github.com/M66B/NetGuard/blob/master/app/src/main/res/xml/predefined.xml).

**(30) Can I also run AFWall+ on the same device?**
Unless you are just testing NetGuard, there is no current reason to use them both, since they cover the same function (firewall),
although with different base needs (AFWall+ needs a rooted device) and ways of doing their thing (AFWall+ uses iptables).

**(31) Why can some applications be configured as a group only?**
For a lot of purposes, including network access, Android groups applications on UID and not on package/application name.
Especially system applications often have the same UID, despite having a different package and application name, these are set up like this by the ROM manufacturer at build time.

This is because Android counts battery and network usage which is normally counted for other applications

Profiles are inconvenient because they need to be operated manually.
Conditions like '*When screen is on*' are on the other hand convenient because they work automatically.

**(34) Can you add a condition 'when on foreground' or 'when active'?**
Recent Android versions do not allow an application to query if other applications are in the foreground/background or active/inactive
without holding an [additional privacy violating permission](https://developer.android.com/reference/android/Manifest.permission.html#PACKAGE_USAGE_STATS)
and at the expense of extra battery usage (because periodic polling is required) anymore,
so this cannot be added without significant disadvantages, like [this one](http://www.xda-developers.com/working-as-intended-an-exploration-into-androids-accessibility-lag/).

NetGuard "asks" Android to start the local VPN service,
but some Android versions contain a bug which prevents the VPN from starting (automatically).
Sometimes this is caused by updating NetGuard.
Unfortunately this cannot be fixed from NetGuard.
What you can try is to restart your device and/or revoke the VPN permissions from NetGuard using the Android settings.
Sometimes it helps to uninstall and install NetGuard again (be sure to export your settings first).

On most devices, NetGuard will keep running in the background with its foreground service.
On some devices (in particular some Samsung models), where there are lots of applications competing for memory, Android may still stop NetGuard as a last resort.
Unfortunately this cannot be fixed from NetGuard, and can be considered a shortcoming of the device and/or as a bug in Android.

Developing NetGuard was quite a challenge and [really a lot of work](https://www.openhub.net/p/netguard/estimated_cost), but fun to do.

A good product deserves good support, which means, in practice, that I am spending 30-60 minutes each and every day answering questions and solving problems.
Just about 1 in 1000 downloaders purchase any of the pro features, so support is basically one way.
This is not maintainable in the long run and this is why advertisements were added.
Purchasing any of the pro features will completely disable advertisements and help keep the project going.
