[Q] Is our information really secure from theft?

If you are like me, you should have all your favorite apps, documents, pictures etc. stored right on your phone that basically gives a full picture of who you are as an individual. You also have been pretty satisfied with the pattern, pin number, password or face unlock or all of these together as a security you have in place to prevent unauthorized access. But here is something that happened by accident that led me down this thought process. While trying to yank out the phone from my pocket while driving (which when you are getting a phone call especially becomes the most impossible task), I noticed that the phone "Power Down", "Restart", "Airplane Mode" pop up was on. This is on top of my regular swipe to unlock with pin number lock screen. This made me curious and noticed that the back button will work to close this pop up and also the power button works to reactivate this pop up. I hope everyone is with me till here. What surprised me was that the phone will actually turn off or restart from this point without the need for an unlock code. This means anyone with rooting and backup knowledge can steal my phone, restart my phone into recovery and wipe it to make the phone their own or just create a backup (CWM) and through that access my personal information. I know that photos and documents stored on the external card is open unless encrypted. But I hoped the internal data would be secure.
What do you guys think about this? Is there any app that would prevent access to the phone while locked via hard keys? What do you do to keep your information safe?

TL;DR version
If phone is stolen and person has knowledge of android they can factory reset your phone, even if you have a password setup. If they enter recovery they can wipe data and factory reset your phone and now it is usable for them.
My theory if you have your phone rooted I wish there was a way to lock the recovery with a password. Unfortunately ODIN will always be available able to get back to stock. Cerberus is a great app to have full control of phone if stolen FYI

As soon as I realize it is missing I would activate the wipe feature in this software.

If I have your phone in my possession I guarantee I can hack it regardless of any security measure you make take, so the best solution is to be able to wipe it remotely.

technically even a remote wipe is not enough if the thief is knowledgeable. I accidentally wiped flashing in Odin with nand erase checkd and recovered everything that was on it using this
http://forum.xda-developers.com/showthread.php?t=1994705 so your never completely safe

Exactly my point like everyone else confirms it here. We have advanced so much to a point that even a 9 year old (not that 9 is too young to know computer basics) who is familiar with basics on rooting after reading through forums after forums can get away with stealing a smart phone now a days. At this point the only way I could think of protecting my data (first priority) and then track my phone is if the tracker is incorporated into the boot loader or recovery itself on top of what ever software you have installed in the OS. So if the thief tries to unlock my phone after a restart, the installed software should take care of the rest but If he/she is smart enough to go via boot loader or recovery then the incorporated tracker can do its thing. Anything of that sort exists?

Did you forget you could just pull the battery to get into recovery?

Why do you need to pull the battery?

You don't, but its easier than going through all of the steps OP posted.

I really doubt my data is worth anything. Pictures of my cats aren't exactly hot commodities and I don't store anything on my phone that I wouldn't publicly reveal, anyway.
I wouldn't be worried about my worthless information, just annoyed I was dumb enough to let it get stolen. Yeah, I know that basically anyone with half a brain can wipe a phone and re-sell it - it always amazes me when people think that thieves aren't smart enough to do that.
I'm cynical. Saves a lot of worry since I just expect the worst, I guess.

They get into your email where it may be more info to compromise.

I would be less worried about the minute possibility of a phone thief targeting your personal information than I would be about your personal data being mined from your phone by numerous applications.
Bottom line is, if you use Google or Facebook, you personal information is already in the hands of giant corporations who will never be held accountable for the theft of your personal info.
Take Facebook for example - within the app, the only time it should ever ping your location is if you are using FB chat and have the location setting enabled. However, even when you disable location within FB chat, every single time you open Facebook it uses your GPS to get your location. Every time.
In addition, although you are unable to see it in action because there is no notification icon for it, I would bet a million bucks it's also pulling your network location if your GPS is off.
Facebook is constantly working in the background - even if you never opened it.
Google? I won't even begin to try and explain the amount of data they are collecting from you. As is T-Mobile, Sprint, Verizon, ATT, etc. every single second that your phone is on with data enabled.
Should we be concerned with some random thief who knows the ins and outs of Android pulling your data? Sure, we should think about it. But the reality is, if you own a smart phone your information is already out there in the hands of companies who will use it to any end they can in order to turn a profit. Period.

ButWhile I see the pros and cons of different parts involved in using social networks and so forth, one thing we can (at least for now) be certain of is that they won't use your credit card information etc. to make illegal purchases and so forth. I know of a person who routinely used the credit card app to check balance, pay bill etc. and next thing he was getting phone calls to see if the purchases made at a casino in Spain are OK?! This is without ever losing the phone!!. So, it could be worse in the case of phone loss. Sure, personal data, pictures and even email to some extent is not as bothersome to me as identity theft. Thank to some anti-fraud features of the banks etc. one can deny and simply not be associated with that activity (of course in legitamate cases). My friend ended up getting another card with different number and they closed the online banking account. He had to re-register all over with another id. So, it can be a big hassle. I heard of cases where people had to hire lawyers and run around courts to prove their innocence due to identity theft. Of course if you keep a picture of your driving licence on the phone, you are really asking for it so... (trust me, one girl was doing this because she didn't want to carry her purse/wallet on night outs)
Having said that, I am always worried if the roms we download here in XDA have trojans or backdoors built into kernels and system files... I know that it is like doubting even the good devs but how do we know for sure? Unless you are really an in-depth expert and figure out all the details such as processes and ports that are open and so forth, how do you really know? The phone's data icons keep pinging back and forth every now and then and at times I wonder what's being sent and what is it receiving... just sync'ing contacts...or...??
Call me paranoid but, after what happened to my friend, and similar stories, I am a bit skeptical about the security and integrity of the ROMs in the first place... Now, mostly I download and try different roms and settle on one that suits my preferences. I use the phone for calls as well as to make general tasks easier in many aspects except financial transactions. In short, I don't trust my smart phones.
For those of you wondering what Google is tracking, (not by any means the only place to look) login to your gmail account and look around different settings. You'll see web history, phone data to name a few..

What security options do we have?

A little while ago my brother had his iphone6 snatched. Now with Iphone, I know cannot be mounted to usb directly or even via recovery.
I know pin, fingerprint etc block access to the phone. I want to understand about other ways to access internal storage to gain access to photos and any other documents
That makes me ask - What security options we have for android - in particular OP3 (have 2 of them) and how can we make it more secure. ? Both my phones have Blu_spark TWRP + Freedom OS 2.10, if that matters.

Just to share, I found following to be foolproof
- Setup Pin + Fingerpints
- Setup Pin / Password for phone startup
This
- Keeps the device encrypted
- Unable to boot without pin
- Unable to access TWRP without pin
- Doesn't auto-mount on USB connect
Still, it would be interesting to hear about any cons of the above setup.

The easiest is to not get it snatched. Or if it does you chase them down and get your phone back. But barring that not alot you can really do and ill explain why.
When someone steals a phone, they dont care about the data on it. They are either gonna sell it or use it. Either way The device has the sim removed with in sec of it being taken and then it is reset or flashed to stock to remove any and all locks. This normally happens within minutes if not seconds of a device being stolen.

Interestingly that was not the case. They remained in contact and kept on asking for phone passcode; which we did not give.
I'm not aware if its equally east in iPhone to enter into (kind of) fastboot mode and erase entire storage. In such case the loss remains of the phone and nothing else ; specially when we may have financial apps too on the phone.

No apple doesn't have the option. Main reason the fbi had to pay to have an iPhone unlocked not to long ago.
Part of the reason I never advise doing any sort of banking on a device as there is just too many security risks. I, mean even android keyboards monitor what you type.

Cerberus is a really nice app... You have alot of options sadly it isn't free! But heyy, it's cheap and it's functional! Other then that keep your device encrypted and a boot password should do.

As long as you're not rooted and unlocked, it will be a bit hard for an thieve to have access to your phone. Leaving ADB on, might as well decrease the overall security of the phone.
I for example was given a tablet which had a Google account synced with it, and resetting from recovery only made me renter the credidentials previously used to be able to pass the setup.
My luck was that the guy left ADB on and with a simple command I bypassed the setup screen.

Not sure about iPhone's but for newer Android phones as long as you are encrypted and have a pin/password set for boot, a thief would just wipe the phone return to stock and sell or use it. 99.9% of the time they just want money so the likely reason they wanted your pass code is they couldn't sell it cause they were blocked from resetting it temporarily. As long they have a physical device and unlimited time they will eventually reset it and get rid of it.

Exactly. If someone steals your device 99.98% of the time it is too use it or sell it. With way your data is meaningless.
As for them wanting your pass code the above is right. But as they couldn't reset it you could have reported it stolen and the police may be able to find it but most of the time they have better things to do then recover a lost cell phone.
I used to work with people that felt with stolen cell phones. I can say the normally. Withing 30 min of a device being stolen the data is gone. And when I say that I mean a complete DOJ style wipe, format and imei change.

this is exactly why that semi-recent feature added by google which requires you to log in with the previously added google account in the phone before initial setup following a factory reset is very useful - it makes the phone unusable/unsellable (unless im missing something?)

That can easily be bypassed by wiping the data off the device and flash a stock rom to it. The only the the FRP does is prevent them from getting at the data.
No its not really. It's so they can send relevant ads. Those that remember smartphones before Apple or Android knows that it is not really needed.

but how can they flash a stock ROM onto the device if the "require PIN before startup" option is selected? how can they flash if recovery has a PIN on it?

Because that is before startup and not the bootloader, even with those set up they normally dont cover download mode or what ever mode that particular OEM uses (not all use the same). In extreme cases with some apps that make it a bit harder or people just dont want to be bothered to mess with things too deeply there are tools available that Will push the update right to the board bypassing all security. Sure its a little extra work but it is a sure bet when you cant get into a device and cant be bothered hunting down getting around it.
Also for the passwords on startup. any password cracker would take out the average password in a matter of min.

This has been very interesting and so much to learn. Thank you all for great inputs.

Once a phone is lost, there's little chance to get it back. Device loss is one thing and data loss (or rather data access) is another. The later at times can have more problems.
I used to keep my id papers (for ease of printing anywhere as needed) on phone (Nokia N5). Lost that phone .. and till date I hope no one used those to buy services, do illegal stuff. That was a lesson learnt hard way

You don't need to steal someone's phone to get a fake ID with their info. 1500 usd will get you that without it.
As for getting nothing in hand. They got exactly what they wanted. The device. Unless you work for the government in a high place. Then your data is meaningless on your phone. You already put it in enough places on line while using a pc that if they want it they already have it.
I could easily steal someone identity with a little more then what they post on Facebook or other social media outlets.

How to Encrypt Micro-SD Card.

The Internal memory is encrypted by default, But i cannot find a way to encrypt the micro-sd card and that`s where i store all my data, photo`s, video`s ect.
If i loose my phone or it`s stolen the micro-sd can easly be removed and read on multitude of devices.
So what am i missing, Maybe i am blind and have missed the option.
Thanks.

Backup Rule #1 Never encrypt backup data.
YOU are the one most likely to get locked out, permanently.
No one will be able to recover the data if this happens, you will be boned.
Meh anyone trying to steal my phone will see red... and lots of it.
Don't flash your phone when out and about. Stay in real time were your attention needs to be!!!
Phone in pocket, out of sight.
Never lay the phone down; get in the habit of putting it in your pocket in unsecured locations.
If the data is that sensitive it probably shouldn't be on the phone...
Always have redundant safeguards for if the data is compromised. Plan ahead!
A rootkit could turn your Android into an open book...

S20 - Configuration Assistant PIN Forgotten

Hi Everyone,
i'm facing a big issue with my Samsung Galaxy S20. here is the story : i forgot my PIN code and decided to factory reboot it in order to recover my configuration without having to remember the PIN I've forgotten, thinking that my Google account will make it for me. When i restarted my phone, the configuration assistant is offering me to deliver the config with all pictures, messages, screenshots etc etc to restore the mobile as it was before the hard reboot. The problem is that it is requiring the PIN code i've forgotten, and i don't know how to proceed to recover it (and the system is telling that there are 5 remaining attempts before removing it from the phone). There are a lot of cherish pictures i'd love to recover on this save and i don't know how to reach it without the PIN Code. Do you know if there is a way to do it ? (maybe with the source code or something ? ) that would be really helpful ! many thanks for your help !

Is it possible to use your Samsung account to recover it?
Can you connect with adb?
Pause, relax, and explore all other possibilities.
Try Samsung and Google tech support, you may get lucky.
You have a SD card slot. Why didn't you use as your data drive? Too late now but learn from your mistakes.
It's possible you didn't forget that password and it became corrupted. I got locked out of a laptop bios like that.
In the future don't set password unlocks for the phone.
NEVER encrypt backup data.
You are the most likely to be locked out, sometimes by no fault of your own... other than using the lock or encryption in the first place.
Always redundantly backup critical data to at least 2 hdds that are physically and electronically isolated from each other and the PC.
I've lost databases, not fun... but educational.
Regardless of the outcome consider this experience a course from the U of Hard Knocks.
My backup protocols may seem like overkill (I use way more than 2 hdds for backup) but it's what's needed to prevent critical data lose. Cloud backup is ok to use but the primary archive should always be hdds that are well maintained and protected.

A5 2017 - Issue when SIM and SD card removed - Your device was reset

Hello,
As the title says, I have an issue with A5 2017 that has Android 8? and current software is A520FXXUGCTKA.
Girlfriend used it before the new phone she got, transferred most of the data, SIM and SD card but A5 suddenly went into some kind of lock.
"Your device was reset recently and it needs PIN to be unlocked. You can't use fingerprint until you unlock it with PIN" - something along those lines.
Is it possible to unlock or flash some recovery to bypass that lock? She already tried a ton of different pins and still can't unlock it - only makes the timer go up.
The phone is not stolen or anything like that. My girlfriend genuinely needs leftover data from there to transfer to new phone.
Hope I am not breaking any rules and if you have any more questions or need more info, feel free to ask me.

Someone may have a better Plan.
The data may be lost if not.
Meh... always redundantly backup critical data to at least 2 hdds that are physically and electronically isolated from each other and the PC.

Your backup plan is easier said then done when a person is not that knowledgeable in tech realm.
She didn't care about backups but she always kept pictures and small amounts of data on a laptop.
Anyway, would you recommend any of the "unlocker apps" you linked?

I was completely computer illiterate in 2004.
Completely Android stupid in 2014. You identify what you need to do and go from there. If you play with what you need to learn, you will learn it.
One needs to learn about hardware as well to make good choices.
There are no shortcuts, it takes time.
One of the first priorities should be data backup. That's one of the main reasons to use a computer, to catalog and store data.
There are only two types of computer users, ones that have lost data, and those that will.
Being of the former group I can safely say that you can never have too many backup hdds and drives.
As for unlocker apps, no clue. I have done everything I can to avoid that unpleasant situation.

Really? I think the data is already lost.
The reason you're in this situation is because you choose to be. Actions or lack of, have consequences.
Most things can't be fixed after they're broke.
