[Security Discussion] nerotNS:
You guys are way too paranoid. First off, if you're all into don't track us down, why are you using the Internet in the first place? Now for the technical part.

The kernel is trying to get the the DNS because guess what? DNS is needed for Internet connectivity. Android is a smartphone and many of its services rely on having an Internet connection. So it's rather normal that a system-level part is trying to establish a network connection. OEM kernels have more of this compared to AOSP because they use their proprietary services.

And sure, you can use 3rd party apps, but they too can contain tracking data, and prior to 4.4/5.0 core system apps were open source, and you still don't have to use gapps.

Next, you can't change hardware embedded data like serial numbers for a number of reasons, security being one of them. If it was that easy you could never track down stolen phones for example. Much like a motor engine serial number in a car. Same goes for IMEI. Then you spoke about the past. Things change over time, it's not the Cold War ETA anymore. Next yes, court orders. According to international law they DO NEED a court order to see your data. And even that is done only in high profile criminal cases. You can read quite a lot about privacy laws online.

Further, yes you ARE good to go. Androids built in encryption system is pretty tough. If your bootloader is locked down, you have no custom recovery, it ain't that easy to get to your data (excluding nexus devices, because of their development nature this can be relatively easily bypassed). Plus, they'd have to have physical access to your device.

They won't receive any of your "precious" data except your rough location and serial numbers as well as your IMEI that will be bound to your Google account. I've already explained why, plus it's for their statistics for example the number of active android devices, new Android device activations on a daily basis etc.

You say you don't use a real name when buying a phone? Well tell me then, what about ID cards? You fake them too when signing a contract? Buying a prepaid SIM card doesn't need a name anyway. And buying a phone? Same thing, unless bought on contract, in which case the ID card problem persists.

Calling encryption dangerous is ridiculous to say the least. And yes, even "two story computers" are gonna have a bad time cracking it. Ever heard of a 256-bit AES?

Finally saying that nobody reviews "boring source code" is ignorant if nothing else. There are tens of thousands of people PAID to do this. It's not a single guy doing it. Plus just because YOU find it boring, doesn't mean everybody else finds it boring too.

Conclusion: Yes, there are ways to compromise security and data. Yes you can block most of those ways. But this level of paranoia is ridiculous to say the least and sounds like something I'd see in a conspiracy TV commercial. Reading trough your posts here I half expected to see "The end is nigh. Hide your children!" kind of sentence. If you believe that we're all monitored, then throw your router trough the window, smash all your tech, and live in a candle lit room. But please don't spread unfounded fear on a public forum based purely on your assumptions, or on what you see on a TV.

Now setmov I'm speaking directly to you. Calling other people stupid because they don't agree with you is a direct violation of xda's rules. Please refrain from doing it again. Thanks in advance.
