Hi,
first of all, my apologies if i am posting this in the wrong section, i read the sticky but i consider this more a discussion rather than a request for help.
Most of you probably know the little exclamation point next to the wifi symbol in the status bar that you get since Lollipop when the network does not offer Internet connectivity.
I tried to locate the feature in the AOSP codebase but was not apt enough to come up with anything relevant, though i did log the network while disabling/enabling wifi to see what it does, and apparently it sends out a couple of DNS queries. I have yet to check it more thoroughly with Wireshark.
So in theory, from a privacy point of view, Google could trace your account/model/network anytime you connect etc.
I am quite interested in how it works exactly, and if i, for instance, could hard code my own server's address into it.
I have read some things that relate this connectivity check to a setting "global captive_portal" (or similar), but was unable to reproduce on Lollipop.
It is also quite strange that apparently no one discussed this before (from a privacy point of view).
So i would be happy to hear what you people have to say about it.
Ciao
