Cloud Search [Q] How to stop Android data usage leaks?

Hi!

I have a rooted Xperia M dual (C2005) with factory firmare (4.2.2). Installed Afwall+ and blocked all network activity except Firefox and K9mail.
But there is still network usage (Android OS).

There is a blog post about this, but I can't link it. Google on "How to debug/examine data usage leaks in Android using iptables"

Does somebody have an idea how can I block these types of data transfer?

Thank you,

Tim

Last time this kind of issue popped up from a few days ago, it was because of tethering. Do you tether? And sometimes the Android OS reads traffic from other apps and is included there. Like for instance, you use K-9. If you use it to access your Google account for mail, that could explain the data traffic there. I'm not an expert in these matters though, so might be a better answer out there.
Need some help, advice, something fixed? Hit me up on Hangouts @ es0tericcha0s and check out my site: http://mobilemojo5280.com for more info!

Hi, es0tericcha0s!

Thank you for the answer. No teething, no Google mail, absolutely no Google account registered on the phone.
Why could a @gmail e-mail account in a 3rd parity e-mail client make traffic on the OS level?

Cheers,

Tim

Weird. Can't even imagine not having a Google account on my devices. lol But most of the IP addresses were Google's so, was assuming that the OS would detect that and thought it might be linked to a Google account and you mentioned having 2 apps and one of them was an email. Stretching a bit for the answer. lol But android is funny and doesn't necessarily work the same across different updates, carriers, and manufacturers, so this kind of stuff can be tricky.
