This one is even harder to analyze, without doing reverse engineering. My advice is to allow it only to local LAN (via AFWall+, if FTP server functionality is needed) or disallow it completely to access any network. Real impact on privacy cannot be learned, because this thing is encrypting some of data it uploads to its servers (in my case they were in mainland China). Complete list of spoils it is making can be found on Androlyzer. This proves that this is not the most privacy-friendly app, to say the least. There are a lot of queries done by File Manager app ( ). Let’s try to identify services one by one. I started tcpdump on my access point and this is the list of queries I received. At this point, we won’t be able to learn which app is responsible for particular query, but we should get a feeling of what to expect.

The first thing to check is DNS queries, the phone is sending to its primary DNS server. They were: Termux, AFWall+, F-Droid, Magisk and Aurora Store. Rest should not have any influence on the results.

Only one is known to contact strange servers – File Manager (). Before performing the test I installed few APKs. But how much data is sent to the outside world on first connection to WiFi? Which apps are responsible for pushing the data into the web? I will try to show that on example of Xiaomi Redmi Go.įor the purpose of the test, I created network that is not forwarding any packet outside.

The fact that Android knows a lot about its user and don’t keep that information for itself is quite well known.
