[CLOSED][APP][6.0+] NetGuard - No-root firewall

[M66B]

I use this app to save data. I have really limited data as I am student and also I don't need more luckily. So I got this question. What controls the Data Usage (Found under Settings) of Android? I mean which system package is responsible for it? I ask cause I want to learn more about Android but I don't have technical background. Thank you for this app. Saves me so much data.

Probably this is just "android" uid 1000.

Probably this is just "android" uid 1000.

I did a little experiment. I pulled out all apps using adb and use developer forum to read their description. They say they have this since android 7. They didn't say which package or packages are behind this.

So I went ahead and started removing them. I am stupid as I went into boot loop. Now I am on a more stable state where I have come across something more interesting.

I broke Data Usage. Nothing happens if I click on it.

But I can turn on Data Saver Mode. So I started Googling... And here I am with no idea what did I do and which system app is behind this.

You made a backup before doing this high risk stuff, right?

I am on stock rom. So no. Pretty much went all in. I didn't know that I'd break my phone. Now I know so I am no longer taking risks. So only removed few apps which are known bloats of Google and some system apps too!

Can you help me find this package? I tried finding answers for hours now but my knowledge is not there to even ask the right questions.

 

[datadoom]

I just found out: com.oneplus.security
I am a developer now. I am a pro!

As a rule of thumb: avoid blocking system apps unless you know what you're doing.

I currently have some system apps blocked, some Samsung stuff, Samsung Bixby, Galaxy, Pass, Pay, etc.
Should all system apps be unblocked? Does this still protect my privacy?

Thanks for the advice.

No, that's not what I mean. You can block some system apps as long as you pay attention to what you're doing.

In your example, blocking preinstalled Samsung apps (like Bixby, Pay, etc.) should be fine as long as you understand that these apps won't be able to access the Internet and work as Samsung intended.

Blocking Android system apps, Download Manager for example, will definitely cause issues - as in your phone won't be able to download stuff and all of the apps that depend on Download Manager to work, eg. your web browser, will stop working properly as well.

TLDR;

You can block system apps but if you're not careful things might stop working / break.

I realized Yandex Navi and Signal were not working. I did not block Google Play Store,Framework and Services. After i remove Netguard, both started to work.

NetGuard is a really good firewall with a correspondingly good logged representation of the data traffic.
The problem is, the firewall is only as good as the more or less savvy user in front of it.
You can completely close or completely open the data traffic of an app, but above all fine-tune it with the host file, which can then also prevent the corresponding tracking / ads.
It would be ideal to have a host file that is relatively easy to manipulate to avoid the sometimes green data traffic / to mark as red (not allowed) in the app and simply add it automatically to the host file (or, conversely, delete it).

"... to avoid the sometimes green data traffic / to mark as red (not allowed) in the app and simply add it automatically to the host file (or, conversely, delete it)."
What does it mean please ?

There is a (unfortunately) German Website (G-Translate) that deals with the perfectly reported firewall NetGuard (Pro-Version) and its setting options. The article is extensive but so far explanatory that you will then understand how the data traffic displayed in green and red (filter setting possible for each individual app) in connection with "ideally additional entries in the host file that are created automatically" (Wishful thinking) was meant.

 

[AndroAlex]

Btw, I'm pretty sure that apps of larger (marketing) companies that are not open source and that are often updated with so-called "renewals" are updated accordingly their IP addresses of tracking and ads in their apps ... ; - )
That's why the IP addresses of host files that are used for tracking and ads protection sometimes change ... ;-)
But of course I can be wrong

Thanks for your reply.

It's difficult to analyze all informations in the German website. Google translate is not "perfect" ;-)
It's too bad because it sounds interesting.

If someone can help us to analyze in english informations of this website, it would be very nice.

Which Host-Lists do you use?

 

[AndroAlex]

NetGuard has already included one host list that you can download and update yourself under Settings, but like any other host file, it is a static list ... you should just keep that in mind.
Here you can find one of the many other information.

 

[orgshooter]

That I am know and it is not the answer of my question.
The more Host-Lists you use the less rules you need per App (red marked entries).

 

[AndroAlex]

The author from NetGuard put a lot of effort into using it as good as possible, so I trust the included (static) host list (from StevenBlack).

 

[AndroAlex]

Everyone surfs and updates differently ... therefore the host list with the IP entries is also an individual matter. Some will have problems with 40,000 "blocked" IP addresses, while the other will have no problems with 250,000 "blocked" IP addresses.

 

[orgshooter]

That's right.
In addition to the Standard List I use the Energized Basic, Goodbye Ads Jerryn70, and Steven Black Unified hosts + fakenews + porn + social (all downloaded from Github).
And i don't have any trouble with several apps or websites.

 

[AndroAlex]

You made a lot of work and effort, or did you just copy everything into one list for a Host file?
A long time ago I used Excel to prevent double entries ... was very informative ...
