Suspicious App data usage

[ThrowawayAcc]

Hi guys, I found this post on stack exchange today

https://android.stackexchange.com/questions/246229/suspicious-data-usage-by-apps

 

I have the same phone as OP and the same packages+ some other suspicious packages. Each of them send out 50-750 kb of data and I don't know to whom does it send.

Here is some more details

 

Why is my factory test app and fingerprint app sending data? Are my fingerprints recorded in external server?

They send out 50-750 kb per day, much more than the person on stack exchange

Hi @ThrowawayAcc,

Looking at the package names, they all look clean.  However, if you want to stop the internet traffic you could use a firewall that can block/track apps internet traffic.  I personally use NoRoot Firewall: https://play.google.com/store/apps/details?id=app.greyshirts.firewall&hl=en  Warning though, NoRoot Firewall is very chatty!  Therefore, you are going to need to allow a lot of things, especially when first using.

I have DNS 66, could I use it as a firewall app as well?

Hi @ThrowawayAcc,

You could.  However, it would be a lot easier to block traffic from an app rather than tracking down the DNS to block.  If you want to stick to F-Droid for apps, it looks like this has a feature to prevent apps from connecting to the internet: https://f-droid.org/en/packages/com.celzero.bravedns/
