Realtime Privacy Monitoring on Smartphones Android sends out info without permission
appanalysis.org

This is the very reason why i use adfree.
I buy my apps if there is an option, but i can't stand some of the adware associated with a lot of apps. it isn't the devs fault as they are probably unaware of the code they were given for the ads. for example there isn't a single reason why Connect4 needs to know my location!

All apps when installed from the market give a list of of all permissions. It's up to the user to not let a tic tac toe game that can access personal data to be installed. As users we need to check permissions for apps we download. Their is great security built into android but as users we must utilize it. Not Accepting suspicious looking apps is on us, but at least we know. Check it out when you get an app. It's give's a permissions list.

yup, i totally agree. the average android user needs to be more aware of their security than an average iphone user.
android users just need to be logical about the internet in general. I find it a GOOD thing. people need to start thinking about their privacy on the internet these days.
apple makes their users believe they have nothing to worry about.... i just find the long term philosophy of this strategy to be bad. i don't care how strict apples policy is for apps, in the end, the internet it becoming a huge part of society and no company will be able to stop exploitation.
i like android because it "should" teach users that the internet is NOT the safest place.

Android Security: A neglected subject (long)

First of all: I'm an OSS advocate and love the idea of open source. Don't forget that while reading this.
Some 2 month ago, I got myself a Galaxy S. It's not exactly cheap, but on the other side, it's really good hardware. This thread is not about Samsung or the Galaxy S. It's about the missing parts of android security.
We all know it from our home computers: Software sometimes has bugs. Some just annoy us, others are potentially dangerous for our beloved data. Our data sometimes gets stolen or deleted due to viruses. Viruses enter our machines by exploiting bugs that allow for code execution or priviledge escalation. To stay patched, we regularly execute our "apt-get update;apt-get dist-upgrade" or use windows update. We do this to close security holes on our systems.
In the PC world, the software and OS manufacturers release security bulletins to inform users of potentially dangerous issues. They say how to work around them or provide a patch.
How do we stay informed about issues and keep our Android devices updated?
Here's what Google says:
We will publicly announce security bugs when the fixes are available via postings to the android-security-announce group on Google Groups.

Source: http://developer.android.com/guide/appendix/faq/security.html#informed
OK, that particular group is empty (except for a welcome post). Maybe there are no bugs in Android. Go check yourself and google a bit - they do exist.
"So why doesn't Google tell us?", you ask. I don't know. What I know is that the various components of Android (WebKit, kernel, ...) do have bugs. There's nothing wrong with that BTW, software is made by people - and people make mistakes and write buggy code all the time. Just read the changelogs or release notes.
"Wait", I head you say, "there are no changelogs or release notes for Android releases".
Oh - so let's sum up what we need to stay informed about security issues, bugs and workarounds:
* Security bulletins and
* Patches or Workaround information
What of these do we have? Right, nada, zilch, rien.
I'll leave it up to you to decide if that's good common practise.
"But why is this important anyway", you ask.
Well, remember my example above. You visit a website and suddenly find all your stored passwords floating around on the internet. Don't tell me that's not possible, there was a WebKit bug in 2.2 that did just that. Another scenario would be a drive-by download that breaks out of the sandbox and makes expensive phone calls. Or orders subscriptions for monthly new ringtones, raising your bill by orders of magnitute. Or shares your music on illegal download portals (shh, don't tell the RIAA that this is remotely possible).
The bug is probably fixed in 2.2.1 - but without changelogs we can't be sure.
But that's not all - there's a second problem. Not only are we unaware of security issues, we also don't have automated update mechanisms.
We only receive updates when our phone's manufacturers release new firmware. Sadly, not all manufacturers support their phones in the long run.
In the PC world, most Distros have a central package management - that Google forgot to implement in Android. Agreed, some phones can receive OTA updates, but that depends on the carrier. And because of the differences in Android versions it's not possible to have a central patch management either. So we do not know if our Android devices might have security issues. We also have no easy way to patch them.
Perhaps you knew this before, then I apologize for taking your time.
What do YOU - the computer literate and security aware XDA users - think about this? Do you think that's a problem? Or would you rather say that these are minor problems?
Very intresting, thanks! The update problem should be fixed with the next release, no more custom UIs and mods from phone manufacturers,at least google said that

Excellent post and quite agree with you. The other significant problem looming is the granularity (or rather, lack thereof) in app permissions which can cause problems you describe without bugs and exploits. I install an app that does something interesting with contacts and also has internet access to display ads. How do I know that my contacts are not encrypted, so making sniffing useless, and beamed back to mummy? Nothing other than blind trust!
I love Android but it's an accident waiting to happen unless the kind of changes you advocate are implemented and granularity of permissions significantly increased. I don't like much about Apple but their walled garden app store is something they did get right although IMHO, they also abuse that power to stifle competition. Bring out the feds!

Sad but true. I'm just curious what Google will do when the first problems arise and the first users will have groundshaking bills.
If that happens to just a few users, it'll get a kind media coverage Google surely won't like.
I've seen quite a few android exploits posted on bugtraq over the years. It's a high-volume email list, but with some filtering of stuff you don't care about, it becomes manageable. It's been around forever and is a good resource if you want the latest security news on just about anything computer related.
http://www.securityfocus.com/archive/1/description
People are bashing a lot about the Android security model but the truth is you can never have 100% protection with ANY solution.
Apple is not allowing any app in their store. Fine. but mostly they are only filtering out apps that crash, violate some rules or they just don't like them or whatever. but they can never tell what an app is really doing. Therefore they would neeed to reverse-engineer every app they get etc. That's just impossible considering the amount of apps....
Speaking again of Android. I think the permission model is not bad. I mean, no other OS got such detailed description about what an app can do or not. But unfortunately it can only filter out very conspicuous apps, i.e. a Reversi game asking for your location and internet access. But then you never know... if the app is using ads it requires location and internet access, right? so what can you do?

Not really, they do blackbox testing and let the apps run on emulated devices they then check if the app "behaves" as desired...
Of course you can't get 100% security and I don't think that's what we're saying, but there is a lot you can do.
Take for example internet access which is the biggest worry I have. The only reason most apps request internet access is to support ads. I now have a choice to make, don't use the app or trust it. That simple, no other choice.
If I installed an app that serves ads but did not have internet access, then the only way that app can get information off my phone is to use exploits and I'm a lot more comfortable knowing that some miscreant needs to understand that than the current situation where some script kiddy can hoover up my contacts.
However, if internet access and ad serving were separate permissions, you could in one hit address, taking a wild guess, 90% of the risk from the wild west that is Marketplace. With a bit more design and work, it would be possible to get the risk down to manageable and acceptable levels (at least for me).
I absolutely agree with you on Apple, one of the main reasons that I chose a Desire instead of an iPhone, but the Android approach is too far the other way IMHO.
Just my tuppence, in a hopeless cause of imagining someone at Google paying attention and thinking you know what, it is an accident waiting to happen.

Well, so why did a tethering app once make it into the appstore?
Also I think there are many possibilities for an app to behave normal, and just start some bad activity after some time. Wait a couple months until the app is spread around and then bang. Or remotely launch some action initiated through push notifications etc.
If there is interest, then there is always a way....

I agree that a seperate permission for ads would be a good thing.
But there are still many apps which need your location, contacts, internet access.... all the social media things nowadays. And this is where the whole thing will be going to so I think in the future it will be even harder to differenciate.
Getting back on topic: I just read that Windows 7 Phone will get updates and patches like desktop windows. That means patchday once a month plus when urgency is high...

But, how do you distinguish them? Today, (as a developer) I can use any ad-provider I want. In order to distinguish ads from general internet access, the OS would need one of:
A Google-defined ad interface, which stifles "creativity" in ad design. Developers would simply ignore it and do what they do now as soon as their preferred ad-provider didn't want to support the "official" ad system or provided some improvement by doing so.
An OS update to support every new ad-provider (yuck^2).
Every ad-provider would have to go through a Google whitelist that was looked up on the fly (increased traffic, and all ads are now "visible" to Google whether Google is involved in the transaction or not). This would also make ad-blocking apps harder to implement since Google's whitelisting API might not behave if the whitelist was unavailable. On the upside, it would make ad-blocking in custom ROMs be trivial.
Even if Google did one of these things, it still wouldn't provide any real increase in privacy or security. The "ad service" would still need to deliver a payload from the app to the service (in order to select ads) and another from the service to the app (the ad content). Such a mechanism could be trivially exploited to do anything that simple HTTP access could provide.

Two more things to have in mind:

Virus

Ok so I have another noob question. Do I need some kind of firewall and antivirus program on my tab? I mean I spent a ton protecting my laptops and desktops, so is the tab already somehow pretty well protected or do I need something?
And if so what do you recomend
Sent from my SCH-I800 using XDA App
Get Lookout from market, it's free. Thats what I use as a antivirus program. It has some other extra features with it too.
By default Android does not accept connections from the outside unless you tell it to.
So for a firewall, to stop applications from accessing the internet (wifi or 3G) you can try Droidwall. It doesn't work with ClockWorkMod though because of the older version of busybox built in to it. So if you are not using ClockWork for your recovery, it should work.
There are very few (only heard of one so far) viruses that have hit smartphones as of yet. But it is good to be prepared.
you do NOT need an antivirus for an android device as it is present... All those reports you see of viruses on android are done by the company MAKING the antivirus software

What do you mean it is present? I didn't know android came with antivirus software. Yes, I have heard teh argument that antivirus software company are the ones making the viruses. But the fact is ( whatever the truth is) if you get hit with one, its still a pain. Since its free for now, go for it.
PS. Viruses has been on a decline though for computers and none made for smartphones yet. Lol maybe symanctec is had to cut cost and got rid of their programmers. I know Mcafee just got sold to Intel. Or maybe they are all waiting for the right time to release them when everyone's guard is down. Do I smell conspiracy Either eay, if the stuff on your phone is important, protect it.
You don't need one.
bpt888, drksilenc didn't mean the antivirus app makers were making viruses, he said that they were the only ones reporting on them.
What has been reported so far have not actually been viruses. It seems you have fallen into the trap those who make apps like lookout want people to fall into.
They report on things like, apps requesting device id's etc. You can see that an app will do this by looking at the permissions it asks for. eg, no need for an "antivirus" app.
If you actually read the "virus" reports from these companies, you'll see nothing is needed.
There are no viruses on Android.
None
Zero
Nil
Android anti-virus programs are a worthless waste. Actually less than worthless, as these useless programs just slow down your system for no benefit.
Android isn't Windows, it doesn't have holes the hackers can easily drive through.
If you concerned about your privacy install firewall (Droidwall for example) and tune its setting to block wallpaper or some other apps connecting to somebody you don't know.
Sometimes applications request internet access without good reason raising doubts in their purpose.
You will need to obtain root privileges to run firewall. Ironically this might lower your Tab protection against network intrusion. However, none of this is known threat unless you unknowingly install trojan and any other malware.
No virus software needed. Seriously it is a waste of time.

Sorry, but this is just FUD.
Windows is far more secure than most people give it credit for - it's just that it is the target for 99% of all attacks because it is so ubiquitous.
If and when Linux achieves some sort of relevance on the average consumer desktop, I'd expect to see a lot more attacks targeted its way and a corresponding increase in security issues.

I agree, but surely the way that Linux (and Android) is made makes it inherently more secure? Without root access there's not much that can be done to truly compromise a Linux system, and Android sandboxes everything

I agree there's a certain degree of additional security provided by sandboxing, but we've already seen APKs (e.g. Z4Root) that can gain root access, so it's not infallible. It is one of the reasons that I use Chrome on all platforms - if you check out Pwn2Own, Chrome has yet to fail, and that it mostly due to sandboxing - however, it is not a panacea!
There is definitely an element of "security through obscurity" around non-Windows OS's. Note the use of the word "element" - I'm not saying that Linux or any other OS are insecure, just that they are attacked less than Windows.
The point is that modern Windows is far more secure than most people realise - any OS given the same amount of attention by the "bad guys" in comparison to others. Vulnerabilities exist in all OS's and will continue to found and exploited.
I'm in full agreement that currently the real security threats on Android are down to users not paying enough attention to the permissions that an app requests when it is installed, but this will likely change as Android gains popularity.
I do pay attention to the apps I install, so I personally don't feel the need for any kind of security suite on Android at present.

Dave

How can free apps generate revenue without ads?

I've gotten the impression (maybe incorrectly) that a lot of the developers here are against ads in apps. I don't understand that, as I believe it to be the only way to generate revenue for free apps. Possibly, it's an issue of youth and it's naivete (the idea that everything is not about about money...ha ha ha). I don't mean that to sound offensive. I was once young too, but as you age and become responsible for more than a couch, a tv and pizza, you realize that money is what makes the world go round.
Anyway...Evernote...this a pretty major app (over 9 million users) with what I'm guessing are some actual employees that support it. That means they're not doing it "for fun," and probably require those pesky little paycheck thingies. It's free and it has no ads. How does it generate revenue?

Donations of course!
But seriously, free apps generate revenue in several ways. Probably the biggest way is companion products or services. Evernote has a premium type subscription that is probably where the revenue comes from.
Even if the app and service is completely free, maybe they sell other products and the app is "Free Advertising" in that if that app is useful, other products by that company are useful and thus I'm going to buy them.
Finally, one of the newest ways that free apps are generating revenue is through in-app purchases. Look at Facebook apps for examples.
Either way, if your company is big enough, there is less of a need for ads in apps to generate funds. This forum is a group of hackers/enthusiasts/developers that for the most part do development in exchange for other people's hard work. Since we do a lot of free apps, we have the "right" to complain about ads in apps We put in the hard work and give our products away for free, and we survive, why can't everyone else!?
I kid of course.
Cheers
Any rooted user is going to be running adfree and droidwall, so looking beyond ads is probably a good idea.

DONATION! Haha. I always donate to those who created apps and make my life easier.
And also not to forgot those who created ROM and KERNAL.
It is a good point to say that some of the most successful and widespread programs and sites are not profitable nor nearing it. Skype loses money, but it's been bought at high sums already twice. Twitter hasn't ever broken even, but it keeps getting lots of funds.
Therefore, if you think you have a successful app in the oven, make it, make it real good, and funding will come later.

You don't need to be young or naive to write free software. It can be a hobby that you do in your spare time (rather than golfing or watching TV).
It can be more economical than other popular hobbies because it does not require major investment or expenditure.

Not any rooted user. Some of us understand that ads generate revenue for the developer so we don't block them.
As to the OP: some less reputable developers will also collect and sell user data for revenue.
The dominant ad business model is pay-per-click. Making money from pay-per-view ads is limited to a handfull of large companies.
With hundreds of thousands of apps the audience is so diluted that most ads mainly serve to annoy the users into paying to get rid of 'em.
Blocking banner ads is not really a problem. If a small percentage of users blocks them the revenue loss is close to zero. If a large percentage blocks them then developers will have to think of something else, just like web site builders had to think of something else when every browser came with a built-in popup blocker.
Popup blockers didn't kill the internet, and AdFree won't empty the app stores.

Unless you program the app to close if the user is using "ad-blocking" software, which is what i do.
And then the next generation of ad blockers will make your app believe that there's no ad blocker running.

Anyone here actually believe that just because you pay money for an app it will not steal your data or open a back door to your device?
Think again!
Even in the PC world, the biggest companies like Microsoft constantly spy on their users, with the official excuse of "fighting piracy".
So pleas don't assume that application price is any guarantee of security, or for that matter, quality.
Also, there are other types of very real and very useful gain to be maid from Free Software (I am reffuring to what people often call "open source", not apps that simply cost 0$).
One example is reputation. When software companies hire developers, they often ask for years of experience, so it is hard for someone fresh to get a job in the field, and even when they do, as all starting positions the pay is relatively low.
Open source projects however, can be worth much more on programmers resume, then simply claiming X years of work for a given company.
The reason is that such projects allow potential employers to evaluate the actual skill of the applicant by looking at his work.
^^^ That is very true.
I just got hired to work for a new startup company based solely on a couple of free Android apps that I made in my spare time.
I do have years of experience in non-android programming though, but still, without those two private projects I couldn't have found a paid-job in Android...

Who in this world has time to read all that? Have you ever tried to read Google’s conditions and policies while creating a Google account? Certainly the answer would be ‘NO’. Do you know that Google had 60 different policies that helped them to collect data from your personal Gmail and other Google apps? Now do you know that they had merged all these in to one policy?
Google will know more about you than your wife does. Everything across your screens will be integrated and tracked. Google noted that it collects information you provide, data from your usage, device information and location. Unique applications are also noted. Sure you can use Google’s dashboard and ad manager to cut things out, but this policy feels Big Brother-ish. Google is watching you as long as you are logged in. It’s also unclear whether this privacy policy move will be considered bundling in some way by regulators. This unified experience hook appears to be at least partially aimed at juicing Google+. Google responded with clarification: Google noted that it already has all that data, but it’s now integrating that information across products. It’s a change in how Google will use the data not what it collects. In other words, Google already knows more about you than your wife.( not my comment go read this.... http://m.zdnet.com/blog/btl/googles-new-privacy-policy-the-good-bad-scary/67893)
Now my question is whether Google is good or bad? Do you need Droidwall to defend your privacy? Or do you still believe in your Brain(better do not believe in brain but use it to think rationally)?
Conclusion: we need a new definition to “virus”...My contribution is Anything that steals your private data is a virus.( no flames needed, no harm meant...just my thought about the relevancy of protective apps like Droidwall, comodo, avg, etc. ...etc)

And if too don't have anti virus then don't use Google. Josin your explanation is wrong. Brain and antivirus both useful.
No need for 2 topics about one thing but thanks for sharing!!!

BOSTON (Reuters) - Cybersecurity experts have uncovered a flaw in a component of the operating system of Google Inc's widely used Android smartphone that they say hackers can exploit to gain control of the devices.
Researchers at startup cybersecurity firm CrowdStrike said they have figured out how to use that bug to launch attacks and take control of some Android devices.
CrowdStrike, which will demonstrate its findings next week at a major computer security conference in San Francisco, said an attacker sends an email or text message that appears to be from a trusted source, like the user's phone carrier. The message urges the recipient to click on a link, which if done infects the device.
At that point, the hacker gains complete control of the phone, enabling him or her to eavesdrop on phone calls and monitor the location of the device, said Dmitri Alperovitch, chief technology officer and co-founder of CrowdStrike.
Google spokesman Jay Nancarrow declined comment on Crowdstrike's claim.
Alperovitch said the firm conducted the research to highlight how mobile devices are increasingly vulnerable to a type of attack widely carried out against PCs. In such instances, hackers find previously unknown vulnerabilities in software, then exploit those flaws with malicious software that is delivered via tainted links or attached documents.
He said smartphone users need to prepare for this type of attack, which typically cannot be identified or thwarted by mobile device security software.
"With modifications and perhaps use of different exploits, this attack will work on every smartphone device and represents the biggest security threat on those devices," said Alperovitch, who was vice president of threat research at McAfee Inc before he co-founded CrowdStrike. Researchers at CrowdStrike were not the first to identify such a threat, though such warnings are less common than reports of malicious applications that make their way to online websites, such as Apple's App Store or the Android Market.
In July 2009, researchers Charlie Miller and Collin Mulliner figured out a way to attack Apple's iPhone by sending malicious code embedded in text messages that was invisible to the phone's user. Apple repaired the bug in the software a few weeks after the pair warned it of the problem.
The method devised by CrowdStrike currently works on devices running Android 2.2, also known as Froyo. That version is installed on about 28 percent of all Android devices, according to a Google survey conducted over two weeks ending February 1.
Alperovitch said he expects to have a second version of the software finished by next week that can attack phones running Android 2.3. That version, widely known as Gingerbread, is installed on another 59 percent of all Android devices, according to Google.
CrowdStrike's method of attack makes use of a previously unpublicized security flaw in a piece of software known as webkit, which is built into the Android operating system's Web browser.
Webkit is also incorporated into other software programs, including Google's Chrome browser and the Apple iOS operating system for the iPhone and iPad.
CrowdStrike said it had not attempted to create software to attack iOS devices or the Chrome browser.
Ok, now a group of hackers control 500000000 devices... an antivirus will slow the phone down more than a hacker trying to run a phone from another continent over your 2G network... just think about it... how can your screen be monitored over 3G in real-time? It can't be done on my 5Mbps PC...
And if you turn data off, then 1GB of data will be sent to google when you turn it on??? Think logic...(where the f**k do you store that??? I think the effect will be noticed right away, and the attacker has no time to take control, unless you are stupid enough to see a 1GB file and not suspect anything...) PCs have real-time protection, but that is because there are terrible threats out there, and they are optimized, they don't slow down... on your phone, you will regret having a phone for 2 years running like **** and then dropping in water, while you could have best performance in those 2 years...
We are not windows, but we are android, and it is the most unsafe mobile OS, if you want a safe one, get from apple... just 2x price at ½ quality...

well i use avast antivirus
but not for scanning viruses
but rather for anti-theft feature and firewall(blocking apps)
and isnt android a java based OS ??
im sure there are not many virus's
that can cause heavy damage

[Guide (Making One)] Please help do a thorough guide to optimising an Android.

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.
Reserved
Upd: I haven't had time, but I'm starting to do a table with all the packages, what they're for and wether to disable them.
You do know that Silverpush do affect both iPhone and Android, right? And "leave at the door" policy or either iPhone or BBM? There's two errors in this sentence. Are you really what you claim to be? Or just someone with an agenda who just created an XDA account?
why would you need an antivirus for a phone if you stick to play store apps?

There are plenty of play store garbage apps with spy ware and crap in them

iPhone (pretends to) be safe and secure and doesn't straight-up violate your privacy by forcing unneeded permission even before installing the app and running tons of spyware as per unbox while giving all your infos out to apps that demand it and more. It's also a question of procedure: iPhone are really easy to fix/secure with a jailbreak, I didn't even root this Android I got and realised how terribly aggressive their violation of privacy is.
But again, I just want to give people the choice as long as their device is secure, that's why I'm learning all the quirks of Android and how to secure them. All our IT guys confirmed that unless you know exactly how to secure Android devices like we did for our computer park, employees better go for an iPhone.
There's a difference between Apple that might have backdoors to the NSA, and Android that is a crazy open buffet for -permitted- informations stealing without even talking about spyware or silverpush. My Galaxy S8 came with apps and packages that were constantly listening through the mic without my prior knowledge, installation or authorisation, this is intolerable. But I switched for a reason, I'll see if using Android is easily manageable or if it's better to ban them from inside use.

Mate my question still stand: are you really what are you claiming to be or you just have an agenda? Some badass company appointed you to decide what is secure and what not. Really? You? In Op you are talking about thinking to allow only iOS and BBM (it's Bbos BTW) only. BBOSS? Really? BBOS was discontinued one year ago...no more updates no more security patches, no more nothing.

That's not my job, but that's part of mine to decide or push in front of committees what tool we should use, purely from a utilitarian, managerial and system POV. None of us beside IT guys ever realised how Android were intolerably insecure, I've had my head in Apple buttock for years thinking "yeah, that's too limited and I heard Android is now as stable and well made".
But I don't want to go back to iPhone either, so here I am sitting with a Galaxy S8 I'm still not using because I don't where to start to secure it, whether I should try to fix everything on the factory rom or just root it.

Okay...what exactly makes you to feel insecure? I understand you're bothered that some apps are accessing your microphone. That's easy... Settings-Apps. Tap on those three dots and chose app permission. You'll see what apps have access to microphone and deny permission for them. Job done. What else makes you to feel insecure?

I put my S8 away for now I went back to an iPhone. I'm using it off-grid to still try and figure out how it works.
Basically my problems are clear:
1. There's no transparency in background processes/services, the component they use and the data they send.
2. The way permissions are managed is intolerable: forcing you to accept non-necessary and arbitrary access to connected components or private information BEFORE installing the app is a form of extortion. The same goes when running the app: forcing permissions that are not critical to the app code actually running is a form of extortion. Baffles me how Google even allows that today.
3. The fact that there's even a need for a firewall and antivirus, and that the official stores is filled with illegal (copyright infringing app so blatant) and therefor myriads of potential malicious apps like Silverpush-enabled one, without any store control or curation on Google's part.
All this means there is no way I will use an Android rather than an iPhone and allow anyone dealing with private or "sensitive" commercial informations using one inside the company. I'm still trying to figure out if going straight to root is the solution, if I'll have to use cryptography for documents and coms, or if I'll have to spend days figuring out Xposed+Xprivacy, Packages Disablers, MicroG alternative libraries, Firewall and Antivirus and god knows what to make it decently secure like an iPhone (which doesn't aggressively violates your privacy and is really easy to secure with a jailbreak...unless there are hidden backdoors which is still far from the probably illegal open-buffet of private and sensitive informations Google provides to any potential malicious websites, scripts or apps).
