[Samsung Galaxy S8 Questions and Answers] OgreTactic:
Backstory: I've always used iPhones, was tired of the bull****, and wished for Android especially the S8. Was shocked, and I'm rarely shocked, but the agressive violation of privacy, the crazy amount of bloatware, and the unoptimised UX and system services overall.

Now, I'm in charge of a wide ecosystem of people using smartphones in our company as well as other companies I consult for. While people always blab about personal privacy (which is a concern of course), what I don't understand is how people dealing with either sensitive, contractual or strategic informations could use Android devices given that it *excuse but there's no better terms* rapes your privacy in every, but also I'm pretty sure, illegal, ways.

For exemple the Sound Detector app, even when disabled, is constantly listening to your environment without your priori knowledge or permissions. In fact it's mainly the permissions scheme that baffles me: on iOS or any PC or Mac, you can install any app without being constrained to accept giving out information or accessing functions that have nothing to do with the app, THEN you can choose what precise permissions, when and why. And of course there's the whole wider problem of usage and data tracking (which I apparently have to install...a firewall??) or even malware (I have to install a separate antivirus for...on a smartphone). Worst exemple being that of course: www.theverge.com/2018/1/2/16842294/android-apps-microphone-access-listening-tv-habits

Now I like Android for all their efforts, development and implementation, as well as Samsung efforts...but I'm on the verge of having to present a report to ban all Android phones (for a "leave at door" Policy or either iPhone, BBMs and any other "more" secure smartphones) like I just realise they did in the US government and other official institutions as well as some corporations...or...understand very well how it works, and devise a clearly guide on how to completely optimise and secure Android smartphones like I would for PCs/Macs.

So here's my mission if you accept to help me:

1. I want to deconstruct how Android works in a very simple scheme for noob.

2. From that I want to list all the system packages and services, to determine those that are critical, optional or bloatware, and actually describe exactly what they're for so people have a clear idea.

3. I want to list all the base applications, stores or packages apps, to determine those that are critical, optional or bloatware, then what they're for and most importantly the best alternative apps to these.

4. I want to list and make a simple schemes of how the device components (sensors, cam, mic...), the different data canals, and the the different permissions are circulating or violating privacy while screwing cpu time, battery and data.

5. Finally I want to learn, understand and create a simple noob introduction to the different tools like Xposed (and XprivacyLua which seems to be the best options), package disablers (I personally went for BK), Firewall, Adblockers and Antivirus (honestly didn't even think I would need those on Android).

So I guess first, I'll list all the apps, packages (and sub-services) that my Galaxy S8 came shipped with that overwhelmed me, so as to know for a basic Galaxy S8/+/Note what is a consensus of what to disable, why, how and by what to replace if there's alternative, while listing basic how-to's of the tools to that. Note that I only know about BK Disabler as of now.
