Hi,
I know this issue is covered a million times, but it never made sense why ABP doesn't block ad in mobile data mode even when all the instructions are followed.
I have a LG F6 w/Android 4.1.2 unrooted on t-mobile, and I can see ABP is blocking in wifi mode when the proxy is set to localhost/2020. But when I tried it in data mode, by following the usual routine of creating a 2nd AP with the same parameters as the orig AP except for proxy being localhost/2020, ads are not blocked. Trying to rule out it being some arcane root access issue, I set the proxy port to 2021 (or kill ABP) and non of my apps can access the cybercloud. Thus I know all my data goes thru ABP in data mode, but it somehow it doesn't do any filtering.
Is the phone encapsulating all the data to t-mobile's own proxy, thus ABP can't discern ads from real data?
