[Q] Best ways to secure personal data in case of theft? - Android Q&A, Help & Troubleshooting

Hi, so Ive gotten around securing my phone and privacy with Xprivacy and AFWall+, though theres something im curious about and that its not very much talked about. My doubts are regarding what are the best practices for securing a phone in case of being stolen, im not talking about tracking apps, lets say I dont care I got my phone stolen and dont want to recover it but what I want to is for my data to be safe from the thief.
The more obvious answer to this is encryption but my current htc sensation is painfully slow with it and there are some bugs that make it hard to use and if it can be bypassed by means im unaware of then itd not be worth the problems. Ive asked on other places and never got a straight answer, assuming I encryption is on and usb debugging (its very easy to get around it afaik) is off too how safe would my data be with a simple pattern lockscreen on it? things like accounts, passwords, bookmarks and all that, I know someone can take out the sd card and see everything on it but I dont store anything but music on it anyway. The only way I cant think of is through the recovery but im not sure about it. The thieve can wipe everything from there but thats all he could do I think.
Im also aware of apps like Cerberus and such but I know these people are not dumb and first thing they do is make sure the device is cut out from any external communication, thats why Im asking for other possible solutions..

[Q] Questions about security of data stored on Atrix

Assuming that my Atrix is always locked (requiring fingerprint scan or PIN to access) when I'm not actively using it, how secure is the stored data? (All data is stored in internal memory, with no removable SD card in the phone.)
I'm specifically wondering about this situation: Say one or more of my Contacts has sensitive info (e.g. a bank account number or the like). Then the phone gets stolen. Could a knowledgeable (or even unknowledgeable) person access that data without the phone being unlocked?
As far as I can tell, accessing the files through USB requires the phone to be unlocked, but is there a way someone could get around that?
Could files be extracted over WiFi from a locked phone?
Does it make any difference whatsoever if the phone is rooted vs. non-rooted?
Is Contacts data stored in a form that could be read by any text editing program?
I know there are third party apps like Moxier Wallet that will encrypt personal info, but for the moment, I'm just trying to understand accessibility to data when the phone is locked.
Anyting is possible if you are smart enough.
Probably the biggest threat to your security is pirated apps. If you are downloading paid apps for free from illegal sources you are at risk of installing malicious software on your phone. Not to mention that an app you use everyday is worth supporting the developer with 99c.
Other than that I know there are data sniffer apps like Shark but I'm not completely sure how those apps work or what information is at risk because I have never used those apps.

Sure, but that's not a very helpful response. I'm not talking about a scenerio where the CIA has unlimited resources and unlimited time to throw at hacking into my phone in the hopes of finding the whereabouts of al-Qaeda's #2 guy.
Can you provide any insight into by what means an individual with above average computer skills might be able to access the data on a locked phone in a few minutes, or even a few hours?

Granted, that's a risk of the phone internally revealing data while it's unlocked, but let's assume that the phone does not have any pirated apps.
The scenario I'm interested in is: A hacker has stolen or found a phone sitting in its locked state. Could he get at its data before, for example, the phone's owner realizes the phone is gone and has the opportunity to remotely wipe its contents via MotoBlur or the like (say an hour or two)?
If they knew what they were doing yes I am sure they could. However, its very unlikely that your phone would be recovered by someone who could extract the info. Most likely your phone would be found by someone without the skills to steal your personal info, unless they have your finger. If you are hanging out with a group of Atrix hackers I guess my advice would be dont piss them off. I think there are more concerning security risks with the apps you use than physically loosing a phone that is fingerprint locked.

I have noticed traces of my own fingerprints on the screen and case. Not sure if there would be enough there for someone to pull and copy the print and use it to unlock the phone.
Since most of my touch screen use is with the index fingers and/or thumbs, it occurs to me that it might be a good idea to set up the fingerprint scanner with my middle fingers, rather than index fingers, even though the phone specifically asks for the index fingers. That way, it's highly unlikely that a suitable fingerprint would be left on the screen. Perhaps that's being overly paranoid, but as the old saying goes, just because you're paranoid, doesn't mean they're not out to get you.

Haha, I like that quote. I do have to say tho you are being WAAAY over paranoid. You really thing somebody is going to lift a print from your screen and replicate it in a way that can be swiped and recognized on your phone? I say if someone goes through all that trouble they deserve to have the information in your phone! I mean, the Atrix is the only phone I know of that has a fingerprint scanner, most people are content with a pattern or 4 digit number.

[Q] unlock pattern lock

Ok, before everyone jumps to conclusions on multiple accounts let me get this out there.
1. I am not a noob when it comes to forums and no how to search ie my search results:
http://forum.xda-developers.com/showthread.php?t=989241
http://forum.xda-developers.com/showthread.php?t=1067003
http://forum.xda-developers.com/showthread.php?t=913958
2. I am not a noob when it comes to android devices and would call myself moderately knowledgable in the subject and really cant think of any other ideas also google nor sprint is not helping in the slightest ( and honestly I dont expect them too).
3. The story below is true and i DID NOT STEAL or receive a STOLEN phone, nor am i some jealous boyfirend. I am doing this for a friend, so here it goes.
My coworkers son commited suicide and has asked me to look at his phone to see if i can find away to unlock it so he can either know if anybody knew this was happening or most likely i think for closure of this whole ordeal. When given to me he had already given the phone to many gestures and gives me the google account lockout screen. the father just wants to see the latest messages on the phone as well as anything that might have come up. now this is what i have done so far:
PHONE: EVO 4G
Status: Stock AKA NOT ROOTED
1. I have taken out the SD card to see if i can grab anything off of there but the last time the text messages were backed up were on 7-31-2011, so that really doesn t help me there. I cant think of any other folders to look in in order to find anything else.
2. The phone was never set to USB debugging so there is no chance of rooting the phone (although i am not sure this would even unlock the phone at this point)
3. His father does not know the gmail account and I have only found a few other accounts through facebook and odd random searches that you can scarely do on the internet. After reading some other posts though I am not sure i could do what i was thinking with this because it only updates the computer and not the password on the phone.
4. Tried calling the phone. The phone doesnt even register as if someone is calling. The father said he didnt turn off the phone yet, and it makes since as i am creepily getting text messages as we speak.
So this is where i am at. I cannot think of too much more. Like i said i dont want the phone, it isnt stolen, and i am really just trying to help the guy out. Google told him becaus ethe kid is older then 18 ther eis nothing they can do and if that is there policy then that is BS especially in this situation. and sprint told him they can do a factory reset on the phone. so those are out of the question.
If you're positive that usb debugging is off, then there's not much you can do.
If you can reset the password to his Google account, and the phone has an internet connection, then inputting the new Google information should unlock the phone. I'm not sure if a connection is automatically created during this process. If you'd like, I can test the theory on my own Evo if you can't get any further.
Most people use the same password for everything. If you can find a password for anything, it's likely that's the password for his Google account. Check his computer as well. If he has saved his login information in his web browser, you should be able to pull that information.
Unfortunately you would have many more options if the phone was rooted. You could do a nandroid backup then sift through the data.img. I'm not sure if the stock recovery allows for anything that will help you. When you get into the stock recovery, it looks like you don't have any options. I believe holding both volume buttons simultaneously on the screen with the red triangle/exclamation point will give you a list of options.
If you cannot get into the phone, the SD card is probably going to be your best source of information - though it's unlikely that you'll get much. Browse through all of the directories. He could've switched SMS Backup apps and the information could be stored in a less obvious location. Try /sdcard/data and /sdcard/android/data.
If I can think of anything else I will post it. Both ADB and MyPhoneExplorer (I'm not positive that's the name) would be helpful in this situation, but without usb debugging on I don't think you'll be able to use them. Research further into enabling usb debugging without access to the OS.
I'm sorry for your friend's (and your) loss. I hope that in some way, even if not through the phone, he can find closure.

Thanks for the response good ideas, and I will try them. Turns out this kid never had a computer and in talking with the friends they only had his other email accounts so I will think of someway to get around that, but anyways thanks again.
Your best bet would be something like the Cellebrite UFED that was getting some attention a few months ago. There are other mobile forensics utilities - I'm not sure if they can be purchased by a single person or if there are guidelines these companies must follow before selling the devices. I'm also sure that they're not cheap, so unless you or your friend are very well off, you probably couldn't buy one yourself anyway.
I took a Computer Forensics course and we spent a week on mobile forensics. This was before Android was popular, and I believe that we used the device on a BlackBerry. The device (I don't remember the name) made an image of the contents which we then looked through using Forensic Toolkit or something similar.
If you know anyone in a computer program, ask if they have access to a similar device. We were allowed to use whatever tools were available during specified times (mainly for lab work, but we could use them for other reasons), so this would be your best bet for getting information off of the phone. Other places, like repair shops (and police departments) may have access to similar technology. If you can find someone empathetic to your situation with access to mobile forensics tools then you may be able to get somewhere.
It's a long shot, but I had the thought & wanted to bump your thread for you in hopes that someone with more knowledge could help you out.
If the device happens to have wifi on & is connected, you can also hack into it over the network. If this is the case and you need more information, shoot me a pm and I'll give you what information I know on ways to do so.

If You Bought a Used Android You Could Be Being Tracked!

I believe this information should be out there for all Android users and i dont recall seeing it anywhere but i hang out here right now and thought i would share what i discovered on accident.
i reference a RAZR M here but INSERT any Android phone as far as i can tell.
***please Devs and such i am not one so ignore my possible misuse of how exactly it operates but i just wanted to share the point of this not how the Android OS operates
i had a RAZR M with ROOT and installed Avast Mobile Security (i believe many others would do this as well) and since i was root i installed it as a /System app. this as some of you may not know makes it kinda part of the OS now. this means that a Factory Reset does not remove it but instead installs it again. i will explain how i discovered this:
- had a RAZR M as mentioned and i installed Avast as /System
- you can rename the app itself to whatever you want like "fletch33" and so anyone who finds your phone wouldnt know it was a security app and try to uninstall it. this is a great feature so i renamed it.
- this will do the standard stuff like locate your device, wipe it, make it beep, etc....
- i decided to give the phone to someone else and they wouldnt want root items or anything so i did a factory reset forgetting i had installed Avast as /System so they would have a clean start with the M
- since Avast was /System it became part of the Factory Reset process and so a what i thought was a clean fresh phone actually still had Avast on it but now since it was fresh and clean there were no signs like an app to remind me i had installed it as root. i honestly forgot it was on there.
- i had selected to get notifications of where the phone is if it traveled a distance but could see it whenever i wanted with a browser login to website and although i had reset it that STILL WORKS! i am getting emails when it moves and can login and see it.
- there are no visible signs that this is on the M (insert any phone)
- in my knowledge the only way the tracking etc... would stop is if i were to ODIN or SBF or whatever the equivalent is on that particular device or i would have to re-install Avast and it would then allow me to put in my passcode and then i could uninstall it.
the moral of the story is that any used phone could have had this done and if not by accident like mine but on purpose for whatever reason.
fortunately i gave the M to a family member and i will fix it for him but it really made me think what it could be used for ....
if this has been mentioned or i am incorrect i apologize in advance but when i started getting emails about where the phone i gave away was located all the time from Avast after a Factory Reset i decided i should share this so that others might take precautions with their second hand Android device.
1. I always Odin my phone and procedure to rooting with in a few short hours of owning device.
And if not, I'm pretty sure unlocking the device will erase everything. (in a lot of my previous cases)
2. And I see nothing wrong with the previous owner being able to track me picking up his wife and taking her back to the white house to make her my First lady
Yep, first thing I would do is wipe the phone properly.
"Factory reset" is a really bad name for the process...it does nothing of the sort.
Um, makes complete sense that you can still track the device. I assumed that before you even posted it. Same way you can track devices through android device manager, moto software, etc etc.
You're forgetting a huge oversight here.......it doesn't really do much good if stealing someones phone, then wiping it, would get rid of all tracking options. Kinda defeats the purpose. Otherwise people would steal someone's phone, factory reset, then go about their merry way and you're SOL...

sure but since most Android phones dont offer a iPhone like recovery and most users dont even know what root it then to me its those people that should have concern.
i always ODIN or SBF etc.. myself if i pick up a used phone but most people woudnt even know about that.
Manufacturers should release iPhone like recovery system so that an average person can clean their phone without tech knowledge and downloading a file somewhere.

Scamware? Tablet locked - should I factory reset?

My wife bought an S7+ from Amazon and it's been fine for a couple of months. She had a popup today which warned that the device would be locked because it was part of a trade in scheme and there was some sort of problem. I assumed some sort of malware but I was working so I didn't do much with it but now the device appears to have locked into a sort of "kiosk mode" where we just get 2 screens:
https://imgur.com/a/Z4N9TLy
All the blurb is plastered with "Samsung Electronics UK" but the domain the email is going to is "tradeinresponse.co.uk" which after some Googling seems to have been linked with some scam stuff in the past.
I've tried safe mode with the same locked screen, plugging the tablet into a PC results in it locking to the first screen.
I can get into recovery and I wanted to try a wipe, but the wife has some drawings on there she's done in Sketchbook that she would like to keep.
I'm a software developer by profession but I work with Windows/.NET and SaaS stuff so I've not got much experience with droid devices (a bit of java here and there in the past, but not so much XP with the OS itself)
So my questions are:
Does anyone know if this is any sort of official thing or is this malware/scam stuff as I suspect?
Is a factory reset likely to resolve the issue?
If I want to factory reset, can I pull files off the devices internal SD via ADB or some other tool before I do it?
Do I have any other options?
Kind of a wind up - I'd just have factory reset it by now to find out but like I said, I don't want to lose any of the wife's data if possible. If she gets anything back I'm going to make sure she sticks it in the cloud.
Any help would be appreciated and thanks in advance!
Always backup critical data redundantly to at least 2 hdds that are physically and electronically isolated from each other and the PC.
Or you will lose data eventually.
Factory reset but you will lose all data. If the drive is encrypted, you likely already have.
Sounds like ransomware. Contact Samsung and do some Google searches. See what you got and if there are any work arounds.
You may need to reload the OS completely if it's a rootkit and running on Android 8 or below.
This could be a nasty little bugger...
If it wasn't present on the device when purchased, your wife either downloaded or installed it. She needs to be more careful!!!
Maybe this will impress that onto her...
Thanks for the advice but I've already googled as much as I can. The domain doesn't go anywhere except a holding page though through reverse lookup it seems there are also other domains on the same host including some legitimate businesses that appear to do Samsung second life schemes for devices.
I've googled the actual lock message but no-one on the net seems to have seen it before.
The wife hasn't installed anything, she got the device a few weeks ago (from Amazon, supposedly new) and did a transfer from her old s6 (that has gone to my daughter) to the s7 using Smart Switch. Since then she's not installed any other applications.
It's not "critical data", per se, it's just drawings she'd like to keep, plus copying stuff onto physically disparate hard drives seems a bit overkill given she can just drop the files into a cloud storage account and have way more redundancy than you/I could ever reproduce by doing manual backups.
I'm posting in an s7 forum about an s7 so it's going to be running Android 10 at the minimum (given that's what the device ships with). Not sure why the comments about Android 8.
Anything she could have installed would have been from the Play store (and I don't believe she installed anything other than what automatically installed from what was on her old s6), plus her apps are from a reputable vendors (Autodesk etc). My son has a tablet and he installs all sorts of crap and hasn't had this issue because the OS prevents stuff like this from happening unless you allow side loading.
Is it possible to install a rootkit from the play store? I didn't think so ..?
So, either it was on there when we got it, it's legit or it's a vulnerability that exists in the OS and we are some of the first people to see it...
You can do what you want but any backup database that requires a password can be lost.
I have close to a dozen backup hdds, there's no way to I can lose my entire database.
At least use 2 OTG flashsticks to completely backup the data but hdds are still preferable.
NEVER encrypt data drives... and verify the backups are complete and readable.
As to how it happened you're going to have to sort that out or suffer the same fate possibly again in the future.
A factory reset seems inevitable at this point.
Afterwards change all passwords.
Malware has always existed on Playstore albeit not much or for long. She may have imported from your daughter's phone.
You got some potentially gigantic problems now.
Personally I would have already gone full nuke by now. It's simply not worth the risks.
In the future hawk the download folder daily for files you didn't authorize. Delete any unknowns without opening. Scrutinize all downloads and installs carefully, always. Scan as needed with Malwarebytes. Online Virustotal can be used to scan smaller files and apks.
There are also maliciously scripted jpegs too that can cause damage to any files in the same folder when opened. Be aware of any changes or strange behavior in the download folder. Vet all downloads before moving into your database.
Use a good brower like Brave and be careful what links you click, in the browser, emails and texts.
I can't even begin to estimate how many websites I backed out of, closed that tab or wiped the browser data over in the last year alone. Better safe than sorry. Zero malware infections in over 1.5 years and that's running on outdated Pie.
Almost all malware, rootkits etc are loaded by the user. Some will self install if the device's security isn't configured correctly or if not spotted on a timely basis. Androids, even ones with out of date OSs are generally very secure unless the user does something stupid... learn or get burned.

With all due respect we aren't getting anywhere here, I don't want backup advice or malware advice, I want to know the answers to the few small questions I asked about whether this is legit and if I can access the device files or not.
You seem to be convinced it's malware, you also seem to be skim reading my posts which is fine - but I don't think your input is helping me.
I'm not going to use a different "paranoid" browser - chrome is fine, the tablet doesn't have a "security configuration" that is any different from the hundreds of thousands of other S7+ devices out there since it's a tablet and out the box it's ready to go. I'm not checking the downloads folder daily just in case some random malware has somehow "installed itself" onto my device, I'm also not keeping random flash sticks and hard drives lying about - I'll just use that geo redundant pretty solid cloud storage like most of the populace.
Yes you can put malicious content in a JPEG or a JPEG header, but it requires that there's an exploit in the OS or the app opening it (for example hiding a javascript eval in the file metadata); I don't think that's an attack vector on a tablet as far as I know given that she only browses, watches Netflix and draws using her S-pen on the device.
She's not imported "malware" from someone else's phone because if you read my post properly you'd understand that it was HER device that she transferred her data from - one that she's since given to the daughter (who has no issues). If you know how Smart Switch works you'd know that it's an unlikely vector (it just transfers data from application storage and then reinstalls the apps from the play store), plus the fact the original device doesn't have the issue...
Stop telling me to "learn or get burned". This is not a "misuse" problem. The wife is on Android 10, it's a relatively new and secure O/S and she didn't install anything she shouldn't have (she didn't actually install anything at all - it was the stock samsung application and the play store that installed the apps she ALREADY HAD on her previous device). It's not a "learn" scenario. Nothing she did should have caused this - if it is/was an OS exploit or some sort of security issue what could she have done to prevent it? Nothing.
What I have done is:
* Contacted the vendor of the device (we can still send it back if they've sent us a refurbed device instead of new as advertised)
* Sent an email to the address advertised to see what response I get (if they demand money then clearly a scam)
I've checked and the domain in the above shares a host with a company called MTR which happens to be a DCC Group company (one of the groups of companies I actually consult for) so worst case I'll speak to someone from DCC Group and see if they can shed any light.
Seems like it might be legit and quite possibly a mix up.
Do what you will... if you understand the origin of that phrase.
Anything that can't be IDed is considered malware until proven innocent
The fact that you're now completely locked out speaks volumes.
Good practices and backup are your only defenses. They apply to the future not the past... so much for flavors
Personally I think it's already too late for that device's OS load and data.
Of course I could be mistaken.
If you really want the data, take it to a data recovery specialist. They may be able to recover it.
When your at the beginning you can determine how potential data lose will end. When at the end, the outcome has already been predetermined by your actions or lack of.
You are now at the end... likely a dead end.
Been there, done that... actions have consequences.
@Charleh: if I were you, I would back up all important data and do a clean firmware flash with Odin. And a factory reset on top of that, just to be sure. Definitely sounds like you got hit by a scammer.

Like I said there's not really any important data on there, just some drawings the wife would like to keep. Also, I can't backup anything since I can't access the device.
I'll probably just speak to DCC group and see if this company is one of theirs.
If the data is lost we are just talking some drawings the wife has done, there's nothing important on there, she just loses the layers (they are stored as multi page tiffs and sketchbook uses those as layers). She has all the images as flat renders on her cloud storage drive and on Instagram.
Think we just need to invest in some extra cloud storage as the free 15gb that Google give you isn't enough to store what she wants at the moment as the images are tens of megabytes each.
Worst case scenario I factory reset and flash it, best case I get someone at DCC telling me what's what.
The bit that gets me is that there are no ransom demands at this point so I can't be sure what's what. Usually by now with crypto ransom malware you are already being given demands...
We will see.

It's not a big deal mate.
Stop flogging a dead horse, the most annoying thing is just that the device is unusable, regardless of me making backups or signing a pact with the devil or putting candlewax on my nips, it wouldn't have prevented this from happening..
The only reason I haven't tried a factory reset up to now is because if there's a chance I can get the drawings off the device I'd like to try it first before I nuke it.
Stop talking about my lack of actions, it's getting really boring. There's nothing I could do to forsee this happening and not my fault the wife didn't put the drawings on her cloud storage.
Go bother someone else with your multiple flash disk tinfoil hat backup routines (I bet you've got a tape drive in that routine somewhere too), stop trying to be helpful by saying "told you so" after the fact, instead try answering the questions I asked.
@Charleh: The way I see it is this:
The device's data partition/internal storage (where the drawings are stored) are encrypted by default, by Samsung. So, unless you can manage to use a MTP USB connection or ADB to make copies of them, then you're locked out and there's nothing you can do to recover them. Since they're located in an encrypted area, I highly doubt that even a professional data recovery business would be able to get them back. There are certain encryptions out there that even the US govt (NSA/CIA/FBI) can't break.
I'm assuming that you're not a l33t hax0r with uber skills, so unless you can successfully boot into Android again, your recovery chances are almost zero.
Or, maybe this company can help you out. It's worth a shot. But if I were a gambling man, I'd wager a lot of money that you will end up having to clean flash/reset, without being able to recover anything.
In the future, think about making copies of this stuff before bad things occur. As the saying goes, anything that can go wrong, will go wrong, sooner or later. I rarely lose access to my data because I'm frequently backing it up.
Good luck!

@Charleh: The way I see it is this:
The device's data partition/internal storage (where the drawings are stored) are encrypted by default, by Samsung. So, unless you can manage to use a MTP USB connection or ADB to make copies of them, then you're locked out and there's nothing you can do to recover them. Since they're located in an encrypted area, I highly doubt that even a professional data recovery business would be able to get them back. There are certain encryptions out there that even the US govt (NSA/CIA/FBI) can't break.
I'm assuming that you're not a l33t hax0r with uber skills, so unless you can successfully boot into Android again, your recovery chances are almost zero.

Thanks - that was a helpful answer. I suspected that droid encrypted the data - I was looking at making an ADB connection using Android tools. Might as well give it a try before I nuke.
I can't use MTP as the device auto locks when I plug in a USB cable.
Like I've said a few times it's not a massive issue if I lose the data - I work in IT, I know the importance of backing up important data. I've seen a client lose months worth of data to crypto-ransomware (they cancelled their backup solution a few months before saying they were moving to Azure soon so they didn't need it).
I've explained though, it's not my device and it's up to the wife to put her stuff on her cloud storage if she wants to keep it. She uses Google Drive for her docs etc.
Worst case scenario I complain to Amazon, wife is saying she doesn't remember the screen having a protector/film on it when she opened it and we still have time to return/exchange it since I have a Prime account.
@Charleh: AFAIK, Amazon has a 30 day no questions asked return policy for almost everything. If you're still within that return window, then I guess you just have to decide whether the loss of drawings is worth returning it, assuming all recovery efforts fail. I bought my Tab S7+ new direct from Samsung, I haven't encountered like what you describe. And your edge case is the first one I've seen.
I think it's possible that you bought a refurbished device that was preowned but sold as new. The original buyer didn't finish paying it off, returned it, it's sold to you, you get this message. It's either legitimately locked, or someone has remotely locked it and intends to scam you. Contact that company ASAP.
Another option is to find a local techie/shop that can remove this lock for a fee, preferably without data loss. They make want to see proof of purchase, if they're legit. This would at least give you the ability to use the device again. People used to bring me locked phones/tabs all the time, this is pretty much what I did for side cash. As long as they didn't outright admit they were stolen, I didn't care.
Ok speaking to Samsung support and it's legit - what's happened is that someone's returned the device to the supplier after doing a trade in with it and receiving a new device from Samsung Trade In.
Supplier has refunded us and told us to keep the device until the issue is resolved with Samsung.
Now fighting with Samsung themselves about it. Absolute pisstake.
Basically I have a brick and although Samsung have the capability to unlock the device through Knox they won't do it until a resolution is found with the supplier.
Fun-times. Sent a complaint email to Samsung as they are essentially holding the wife's artwork to ransom because of an issue they have created with the rules of their trade-in program.
I've already received the refund too - sounds like the Amazon reseller is trying to wash their hands of it.
@Charleh: So, they refunded you AND they're going to let you keep the tablet? I'd be quite happy with that.

Depends if the tablet is ever going to be functional again...
Fingers crossed!
Time to reflash, ODIN or do whatever and see if you can and up with his + hers new(sort of) tablets.
Hello, some solution?

still ongoing - Amazon is trying to get hold of the original supplier but they've gone dark; I complained to Samsung and they are looking into it, just waiting for a reply.
They took almost a month to get back to me - only did so when I started complaining publicly on all social media platforms (Twitter, Instagram etc) - they don't like it when you do that.
Will update when I know more.

Sorry to hear it's taking so long. I'd be super pissed. Next time, buy direct from Samsung, you wouldnt have to deal with this ****. Because they wouldnt sell you a used/refurbished device unless it's clearly marked as such, and i'm pretty sure they only sell new devices anyway.
Can you post a link to the seller's Amazon page? They could be a fly-by-night op.
If you cant get your money back or an exchange, just contact your bank/card issuer and do a chargeback. This is a last resort ootion, if nothing else works. Explain the whole situation to them. Chances are, they would force the seller or someone else responsible, to give your money back. The only caveat is that if you wait too long, it might not work. i've inititated chargebacks against sellers who dont respond to support requests, it usually worked in my favor.
Edit: If you go the chargeback route and Amazon is forced to refund your money, they may retaliate by banning your account. it recently happened to a friend. Just so you know.....

Question Help me reverse engineer this mod? How do i get my phone back to stock rom, and regain full control over it? Unroot?

I have a A52 5g and a tab S7+ wifi, that are both remotely controled and monitored, and serve as gateway to my home network and basicaly every device connected to it. I noticed it at first and mew NOTHING related to this, didnt even know what open source was. Since then i have come to understand that, somehow, my phone seems to run a custom version of android, my guess is, built from AOSP and designed to disguise itself as oem samsung ui, but in background enables remote access and total takeover of every function. I have discovered, using total commander, that storage has been partitioned in 2 separate locations, and that one folder in there is called root system file, and filled with data/apk/installkits/etc.. this has me asking for help in 2 specific questions:
Am i holding a rooted device or is there another possibility that creates this situation? I was convinced its rooted untill i read here that root prevents from using samsung pass, secure folder etc.. and those seem to work on mine(or is it a version of those apps?) If its indeed rooted, will it wype everything if i flash it with the stock rom? And should i trust a small cell repair store to do that or learn how to do it myself?
2: i have bought 3 brand new phones since august, and made sure not to use my usual accounts, no use backups, not even set it up near my home wifi, and it almost instantly started self installing harmful software in background. I see no other way for it to link itself to be owned by me at initial setup, but for the sim card, new of course, but with my usual phone number and service transfered to it. Is that enough to make a breach and compromise a new device? If so, what would be different after fpashing the stock rom, if everything reinstalls itself? Do i need to change my number? Change cellular service provider even? I know its an unusual request but im a fast learner, i have compiled lots of technical info on specific apps, ip's, servers, build id numbers etc.. that i know would make more sense to anyone more qualified than me, and i am about ready to try and wype/flash the thing myself, i just would feel better with a little help since i have gone this far pretty much alone, since no service provider or manifacturer actualy feels like this is their problem to solve....
Here you can download firmware for your phone and flash with Odin, which you can also download at the bottom of the page, there are instructions on how to do it also.
Make sure to download correct firmware for exact device you have. There are few different A52 5G models.. SM-A526B, SM-A526U, SM-A5260, SM-A526U1, SM-A526W.
You will lose all data after flashing new firmware. After this your phone will be like brand new from Samsung..
If your device is rooted then that means your warranty is void and manufacturers and carriers are under no obligation to help you.
I'm trying to understand your situation but its so conflicting I don't know where to begin.
For example, you say your device runs a custom AOSP with a Samsung UI. Thats exactly how it actually works. Samsung take the AOSP, customise it with their own functionality, then overlay their own skin as the UI. Theres absolutely nothing unusual about that.
I'm conflicted as to whether your rooted or not. If the manufacturer or carrier has physically seen the device and won't repair it then that would suggest your definitely rooted. If you spoke to them virtually and told them your rooted then they will use it as an excuse whether you're truly rooted or not. The partitions you mention could be the internal storage and an sd card which can be seen non-rooted. I dont know what you mean when you mention a "root system file". Is it an actual folder called "root" or is the app you're using just telling you that you've reached the "root" of the filesystem? I can't quite work out what you mean. You also say Knox-powered apps still work which just adds to the confusion.
You stated you have had 3 new devices and they all self-installed harmful software. To get one device compromised is possible. To get three compromised means your either a high profile government target (which I doubt because they wouldn't be so sloppy as this) or your doing something to compromise your own devices such as continuously visiting dodgy websites.
Flashing will fix things but so would having a new device. The only common denominator is you so either you're doing something wrong or you truly are a government target in which case I wish you good luck!
First let me appologise for the long silence, i cut off most online activity for a while and just read your answers. To clarify, i have not solved my prolem yet. But ill try to explain better what you ask about my situation:
About de os version arobase40 got it right. I Asked google play help reps. And a stock samsung version of android would not trigger googles warning about running a custom version of android. So that point to a modified after-the-fact more than to the fact samsung has their propierary version installed.
About beeing rooted or not, ylwhat you are asking is what im not totaly certajn of, also. I know partition can happen without rooting, its seems to have created a "virtual sd card" since its named as such when sd card slot is actualy empty. About the root files folder, i cant say for sure, all i can say is that its holding a large amount of Gigs that dont get taken into account when looking at storage capacity and usage, and accessing that folder gives me a message that root files cant be access from this device. Does it mean my device had root acess privileges revoked to prevent viewing files that hide what is given control of the software remotely, so i dont find out or have the capacity to remove or alter those files?
What is absolutely sure is that if it is rooted, it wasnt done by me. As for the chance the devices were not factory brand new, 1 of them was not, got it opend box from amazon, a saudi arabia version, but my prkblems had started months before getting it, did not keep it more than 2 months, and all others before and since are 100% pure factory new, some directly from my cellular service provider, as financed device came with 2 year agreement of service,(actualy 2 of them i got this way) and the last one is my tab s7+ i got online directly from samsung canada website, on preorder, delivered on release day.
And lastly the fact i cant seem to shake those persistent leeches, is not from having reckless habbits online, but from having careless and uneducated habbits before that all started, usual older lazy dude stuff, like not changing my wifi password after a ruff breakup with bipolar psycho ex gf, or having only a few passwords reused on most my accounts. I have stopped doing those things long ago now that i know better, but i suspect that i could have been unaware something gettnng installed and staying dormant for a while, maybe? The ex had way more opportunities than needed to do something like this and is more than psycho enough to realy do it also. For having the skills to do it, lets say she has "assets" that can easily get her guys willing to help about that. It may also be coming from somwhere else, but as you say im not a super spy or a high ranking gov. Official. Im not even that interesting, and have absolutely no usable id for fraud or anything, my credit history would raise more red flags then there is in all china. So after so long struggling with this still very active, i cant even think of a rational reason to do so much effort into this, theres nothing to gain, i only can imagine that maybe a twisted mind seeking revege, or with a sick way of amusing themselves could see the point to all that, but i dont realy care. I only want to get rid of it.
As for the way it manages to be so much persistent, i can only see one option left i didnt remove from the process, and its through my phone number/account on the sim card, even a new sim on a new phone, still is linked to my cell service. I did initial setup with only that new sim card, accounts freshely created during setup, with no info or anythink linkable to my previous accounts, and even did it sitting outside, far from any building that could get me in range of a wifi network. And it still was no more effective at staying secure.
Thats why i did not yet try to flash a stock rom myself on my device, because it would, at best, become exactly like it was when brand new, and i know that this is not enough to keep it secure, and that means theres still something im missing in the whole picture.
