SM-710 Multi-user mode broken? - Galaxy Tab S2 Q&A, Help & Troubleshooting

I recently retired my son's Galaxy Tab 2 (7") for a new SM-710 (updated OTA to 5.1.1). The old Tab 2 (running CM12) was setup in multi-user mode with him as a restricted user. It worked great - I could limit his access on an app by app basis, his data didn't cross-over into my data, he could log into services with his own account etc etc.
So I had intended to setup his new SM-710 the same way - me as the primary user, him as a restricted user. One HUGE problem - the Samsung (TouchWiz) version of Lollipop seems to be missing a critical menu item that is present on stock Lollipop devices. I can't find the "add users from lockscreen" option in the USER settings. On stock devices there is a menu button (top right) where this option is located. It is usually defaulted to unchecked, however on the Samsung version, the device behaves as if the option is checked, and yet there is no menu item to uncheck. This results in both the "GUEST" and "ADD USER" items appearing in the multi-user lockscreen menu when the device is locked. This is a problem for a multitude of reasons. My son could simply create a new user from the lockscreen and use that account to bypass all the restrictions I have placed on his account. Moreover, anyone else could do the same thing, making it impossible to secure the device.
I have tried a few fixes that I found here and elsewhere. All of them required me to root the device, none of them worked (build.prop edits, sql db edits etc). Happy to describe in detail what I tried, but didn't want to make the post any longer that it had to be). Has no one else noticed this problem/error/bug? Am I missing something obvious?
Any help / insight would be appreciated.

Have a look at Samsungs' "Kids Mode", available in the Galaxy Apps store. It is supposed to be their solution for handing your tablet or phone to your children. It requires a pin code to leave the Kids Mode. However, I suspect it is targeted at rather youngish kids.
My T815, which is still at 5.0.2, doesn't even have the options you describe. I'm a bit annoyed that Samsung has spent time disabling features that just come for free from Google.
The build.prop edit should have worked according to other threads. I'm not rooted, so I can't tell.

Thinking of switching, but I'm looking for 2 specific apps

I have been using Android since the G1 launched, I took one break from it about a year ago to give the Nokia N9 a try (great phone, poor battery life). I am considering switching to Windows Phone 8 (Lumia 920) after it launches. There are two apps that are really important before I make the switch though.
- LBE Security Equivalent. This is a 'firewall', but for application permissions. You can have it prompt you that application 'x' is trying to read from contact data, for instance. If something this exact isn't readily available, is there at least a network based permission firewall? Some applications are fine to use, but I don't necessarily want them to connect to the internet.
- Tasker. This is the bigger of the two that I need to have. If you're unfamiliar with it, Tasker lets you change any device settings, based on any other condition. E.g., if it's between 8am-5pm and I can see the wireless network, "Work", then put the phone on silent... if it doesn't meet those conditions put it back on loud. Very basic example, but I need something like this because it makes my life a lot easier.
I searched around and couldn't find anyone really talking about either of these options too much, can anyone help me out?
Neither one of them is possible with the current SDK, maybe when wp8 pops up.
Windows Phone does not allow any Apps to interfere with System Settings or other Apps. All Apps are sandboxed with only certain interaction points to exchange data or embed themselves into the Hubs. Having looked through the leaked SDK this is not changing with WP8, although there are additional interaction possibilities other Apps functioning as well as system settings are still off limits.
You can look at what permissions certain Apps request before installing them but the only thing youncan do then is to decode not to install them (aside from using background processing and using location data - those can be configured separately).

[Q] Capture Stylus events before they go to Apps

Reposting from where I previously put this, on the suggestion that folks here might have more idea what I am talking about.
Yes, this is a question but I couldn't see that it fit in better to one of the other forums. If I am wrong please accept my apologies and redirect me, thanks.
I'm trying to work with a custom build of Android based on KitKat to incorporate a stylus, copying some of the functionality (though not code) from Samsung which sells Android-with-stylus builds for e.g. the Note 3. I'm not including details of the specific device because right now I am working on a custom dev device and my aim is to write code which is generic enough to be usable from any Android (based on KitKat). The build (written by others) already incorporates drivers and sends stylus events correctly as motion events etc. Programming at the app level I can receive onHover, onTouch, onClick etc
The specific functionality I am trying to achieve is to pick up a stylus-button-click while hovering. It's perfectly possible to do this in any app, using an onGenericMotion Listener.
However, I want to make my "stylus-action" have system-wide effect - so that anywhere (in any other app, or in the launcher or whatever) I will pick up the event (prior to any other app) and bring up my custom menu. (just like AirCommand in Samsung Note 3) I guess in my custom Android this would then make that particular action somewhat protected or unusable for other users, but I'm ok with that.
In older Android (prior to ICS) you could try something by putting up a System Overlay (i.e in regular app code, without hacking the ROM at all), but this is no longer possible.
This is not an attempt to tapjack or whatever, I understand why this functionality has been removed from the domain of the regular programmer, and I don't want to regress my ROM back to pre-ICS behaviour by allowing the System Overlay hack. Now I am programming the system (if my change is good enough I'd like to submit it back to AOSP) so I would like to know the best method to address this. Since Samsung have already done this, it must be legal (using legal in the terms of "Android will allow it"), and I want to do it right.
Is it possible to write something similar to the System Overlay when you are running from a system service? Or is there a good choke-point to capture events before they are broadcast to the current running apps?
I was looking at (sorry, not allowed to post links) AndroidXRef /frameworks/base/core/java/android/view/View.java specifically in the function dispatchHoverEvent() which looks like a promising place. My naive idea is that I would place code here checking the MotionEvent to see if the button is pressed and if it is, don't call any listeners and instead call my little menu app (or broadcast a custom message, or something anyway). However, I've never written code on the ROM level before (LOTS of experience writing app code) so I don't know if this is a really bad point or a good point to add in code. Should I be putting things at a higher level or a lower one? Will this capture all events or not? Is it all just trial and error?
If this is the wrong place to ask questions like this, please tell me where on XDA I should be asking it. If it's the right place - please answer
Thanks

Quick Qs - Wanam Xposed, Tethering, and disabling OTA

Hey folks!
I followed the instructions posted by allcaps33 at http://forum.xda-developers.com/showthread.php?p=53549710 to get provisioning disabled, and the native hotspot app is working for me now! I just wanted to confirm if this was an operation similar to running Wifi Tether Router on an unlocked/rooted device (I had an S2Sky prior that I tethered off of regularly). I've got one of those too-rare Unlimited Data plans and am traveling cross-country, made possible by being able to tether my laptop to my phone to work. Just wanting to confirm that this was relatively as secure as using the Wifi Tether Router on my S2Sky. On a semi-related note, that app doesn't seem to want to run properly on my S5; when I click Enable Router it turns on the Wifi, which immediately connects to the house's wired router. It still broadcasts but doesn't send data, and it's hit or miss if a device can even connect to it from there.
Next question - I'm used to flashing a CM ROM within the first couple days of getting a new phone, which doesn't seem feasible just yet with the S5 (from what I can tell anyway; I'm not used to having a current-gen device). I've heard about the myriad evils of OTA updates, and was hoping to get help on how to disable them. I would like to avoid my device upgrading to a point where my above-stated desired functionality is disabled. Ideally, I'd like to get rid of the various bloatware apps as well, though am not sure how to go about that.
I appreciate your time and support, and thanks for being a community that's always been there for me as I derp along with my fancy internet boxes!
Hi!
The absolute easiest way is to use Rom Toolbox. I have the pro version, but I believe it's available in the lite version as well.
Download and open up RTB.
Tap on "App Manager"
Then scroll down until you see "AT&T Software Update"
Tap on it.
A popup will display. Swipe from right to left, and you will be on the "Advanced" tab.
Scroll down and tap on "Advanced Freeze."
You will come to a screen which shows you the Activities, Recievers, Services, and Providers. Tap on EACH box/line. This will Disable OTA services.
We're not done yet!
Go back to the App Manager screen again, and repeat the process for an app called "LocalFOTA"
Finished!
I also Disable most of the bloatware and Knox this way.
Have fun!

Now for the hard part...
Yes this can be as secure as the other the tether. Ensure you use and change the password service with the app.
As for the tether turning your wifi on, it is supposed to do that. The best way to get this to work is to turn the tether on and off (then on again). If this does not work, try emptying the data/cache for the built-in tether app. And start from scratch.

KNOX - What is it? I'm under the impression it's some sort of security for the phone, to protect from malicious activity that you might not be aware of, but also that it'll "tattle" on you if you mod your phone in a way AT&T doesn't approve.
Knox is two things.
1) It is a security container for apps. It works as both a license/drm type software for Samsung official apps.
And
2) Android contains a root environment at all times. This is what makes SU possible. It used to be quite easy to invoke Android system calls as root.
Root is actually separate from super user. Knox, like SEPolicy, helps dev companies detect, halt, and/or hinder apps, not su itself, but apps that that use these root system calls.
Be wise, even though Knox itself does not "report" these types of actions, it still logs them. And there are other apps that can read these logs and send out these reports. I should say (and I'm only guessing) that only work/company issued phones are setup like this. Not your personal phone.
In fact, our phones actually contain a file which logs all root system calls. It has nothing to do with Knox but, I believe this binary is what hinders us open devs, but makes it easy for Samsung and AT&T to restore/repair our phones.

T813 6.0.1 - Open with once, set as default option missing.

Hi all,
So this has been bugging me for a while and I can't seem to find much info on it on the net regarding our Galaxy Tab S2's. In all their wisdom Samsung removed the ability to open a file/link etc with a app just once, instead when you choose a app to open a file with it will automatically set that app as the default. Really annoying when you open certain files with multiple apps (eg links, media files etc). Only way to chose another app to open with is reset the apps defaults, which is tedious and extremely annoying. I've tried 'better open with' but that doesn't work for all media types (links from Chrome is one type that comes to mind).
So does anyone know how to reenable this basic functionality that has been present in Android for a very long time? Hell, currently it's worse than idevices
(On a side note, when I first used this device I thought to myself 'wow, Samsung hasn't butchered the Android interface this time'. How wrong I was... Why Samsung, why!?!?! You've removed functionality with zero benefit!)

Samsung services dialling home to China (360.cn and 360safe.com) after Pie upgrade

Having ran NetGuard in logging mode for a few days now I've noticed that many of Samsung's in-built services are contacting web services associated at multiple DNS subdomains under:
- *.360.cn
- *.cloud.360safe.com
A lot of them on unsecured HTTP port 80 (some go via HTTPS port 443).
Services I've observed this behaviour so far are:
- Samsung ApexService
- ANT+ HAL Service
- Application installer (com.sec.android.preloadinstaller)
- Assistant Menu
- AirCommandManager (com.samsung.android.aircommandmanager)
- Plus too many other default services to list (most of which cannot be disabled)
Phone's running on stock unbranded SM-N960F build number PPR1.180610.011.N960FXXU2CSA2.
I've scanned the phone using bundled Device Care's McAfee security scan with no findings.
Has anyone else observed this behaviour?

I haven't looked at this as closely as you have,but,I'm guessing it's all tied-in from the Device Maintenance section of the phone.
The name of the company Samsung is currently in bed with is QIHOO:
https://en.wikipedia.org/wiki/Qihoo_360
https://seekingalpha.com/article/4165136-cheetah-mobile-lost-samsung-relevant-risks
Remember/heard of Cheetah Mobile (of Clean Master infamy) ?
https://www.prnewswire.com/news-rel...mobile-security-and-innovation-300043298.html
Well,that's who used to be in partnership w/Samsung & the Device Maintenance aka built-in Clean Master to most,if not all Samsung mobile products.
Fast-Forward to present day & we still have the crapware on our phones,likely scraping info & selling it to anyone interested.
Now,it's just with another company,presumably one with friendlier terms for Samsung.
As you've probably noticed,you can't fully disengage/disable/deny all permissions here,less root (or ADB disabling/package disabler apps).
At least you have a phone that's rootable & can cruise the ROM scene for one that leaves this crap off the phone.
If root isn't an option:
Set up your phone & apps,fine-tune as you like for battery optimization on a per app basis/permissions/etc....
Then,either via ADB or a package disabler,disable the apps responsible for the crapware,especially the ones related to Device Maintenance.
https://forum.xda-developers.com/ga...laxy-note-9-bloatware-removal-thread-t3857508
Follow the link in the OP to the S9/S9+ forum/thread,it gives a better idea of what each .apk actually is/ties into.
Here's the app I use to disable crapware/things I don't use:
https://play.google.com/store/apps/details?id=com.wakasoftware.appfreezer
As to which apps to disable,the S9/S9+ thread,while not an exact match,should give you info on what to disable to stop the phone from pinging the 360 mothership & hopefully,not having any ill effects on the apps you want to keep on-board.
If you want a better idea of how each app is interconnected throughout the phone,use these two apps to take a look:
https://play.google.com/store/apps/details?id=com.ubqsoft.sec01
SD Maid (Pro):
https://play.google.com/store/apps/details?id=eu.thedarken.sdm&hl=en_US
(See the App Control & file manager sections of SD Maid for detailed app info).
Anyhoo,back to curbing the nonsense:
Whichever method you use to disable,should you choose to do so,start with this one:
com.samsung.android.lool (Device Maintenance).
This will make the entire Device Maintenance section inaccessible as well.
That is why I suggest disabling vs outright uninstalling (which necessitates a factory reset to get it back).
You may need to access Device Maintenance for whatever reason from time to time,hence the recommendation for disabling vs uninstalling.
Continue monitoring for a day or so & see if the pinging to the Mothership subsides,or hopefully puts a full-stop to it.
Please keep us updated on what,if any actions you take w/the results. :good:
Excellent overview, it's quite an eye opener thanks for the info.
I've disabled and force-stopped "com.samsung.android.lool" (amongst other junkware) and so far NetGuard hasn't shown a single network log entry to any of the 360 domains. I've uninstalled all 4 Facebook packages. Continuing to monitor this closely. My thought is that I can re-enable "com.samsung.android.lool" from time to time whenever maintenance is needed and then disable it again. Even better Adhell3 might be useful for blocking "com.samsung.android.lool" network attempts whilst retaining it for device management purposes however I haven't tried this yet.

I was gonna post this in a bit (just noticed it myself this afternoon,LOL) ,but,it looks like you have added the other two .apks to your disabled list:
https://forum.xda-developers.com/showpost.php?p=78103170&postcount=123
It'a a shame the mfgs aren't required to be more up-front & state ,in common use language where the print is larger than a gnat's ass, the exact nature of the .apks & even more control over the services installed on them.

The closest to a manufacturer application list I came across was:
- https://support.samsungknox.com/hc/en-us/articles/115015195728-Common-Criteria-Mode
- For example https://docs.samsungknox.com/CCMode/N960F_O.pdf
This seems to relate to computer security certification known as Common Criteria:
- https://en.wikipedia.org/wiki/Common_Criteria
So the dial home behaviour seems to have passed this security certification (or perhaps the network flows were not part of the certification process). We can only guess...
I've had to reenable the following items to get APK installs to function (either through Play Store or locally stored APKs):

com.samsung.android.sm.devicesecurity

IIRC,something like this was mentioned in the S9/S9+ debloat thread.
I didn't mention it earlier as you hadn't reported any issues,but,glad you were able to figure it out/find the same info I'd stumbled upon.
Well after a day of usage I can say that battery life is poorer without "com.samsung.android.lool". I've enabled it again now and blocked its domains via Adhell 3:
Code:
360.cn
360safe.com
*.360.cn
*.360safe.com
Furthermore I have disabled its WiFi and Mobile network access in Adhell 3. However this block is bypassed whenever applications using Android's native VPN facility are switched on so its not absolutely fool proof. Similar blocking can be done using NetGuard itself as long as you keep it switched on and filtering continuously.
I'll keep an eye on which other domains it attempts to contact.

Well after a day of usage I can say that battery life is poorer without "com.samsung.android.lool". I've enabled it again now and blocked its domains via Adhell 3:
Code:
360.cn
360safe.com
*.360.cn
*.360safe.com
Furthermore I have disabled its WiFi and Mobile network access in Adhell 3. However this block is bypassed whenever applications using Android's native VPN facility are switched on so its not absolutely fool proof. Similar blocking can be done using NetGuard itself as long as you keep it switched on and filtering continuously.

How much of a difference in battery life are we talking about?
It felt to be about 20%. Is Pie without Device Maintenance expected to put applications to sleep? I am guessing sleep is the major factor here (opposed to cleaning up caches and other storage capacity functions of Device Maintenance app).

I would like to think so,hoping Device Maintenance isn't ingrained to the level where it breaks the native Doze feature in Android.
JMHO,Device Maintenance seems to be just like Clean Master,running on top of Android/counterproductive,putting a hat on a hat,so to speak,LOL.
I haven't had a Nexus device since the N6 & never had a Pixel,but,I'm pretty sure none of 'em have DM..................................
Whenever I decide to update to Pie,I'm going to continue as I am now:
Battery Optimize all apps that I don't rely on for auto-updating or push notifications & then disabling Device Maintenance.
If something starts acting up,only then do I re-enable DM,take a look at Battery Optimizing for whatever is affected & again,disabling DM.
Guessing you've just recently updated to Pie.......
If it were me,I'd continue to disable DM & give the new OS upgrade a week or so,see what your battery life looks like then.
Battery life loss could be due to some user-installed apps that aren't playing nice w/Pie & not due to DM being disabled.
You will find the logo or text "powered by 360" on storage screen in Samsung device management app.

I have taken your advise a few weeks ago and have concluded that removing DM whilst manually optimising all individual apps has resulted in no battery loss (in fact it has probably improved but this is within a margin of error). Thanks for your guidance.
Unless you need to connect to a Chinese domain for whatever reason, just block *. cn for good and forever about it.

Was original poster was the only one who had this issue?
Is this a samsung thing or all androids?
Can this be a security risk?

Should be only Samsung phones. Interestingly i haven't seen it dial home since my original post and up until i uninstalled the Device Care package. Samsung might have changed the domains the tool dials home to.
