security flaw on lockscreen

DISCLAIMER*** I DO NOT OWN A NEXUS 5, AND DO NOT FOLLOW IT HEAVILY THIS IS PURELY BASED ON MY EXPERIENCE TODAY AND MY YEARS OF USING ANDROID OS. I DO NOT USE IT DAILY AND ONLY USE IT EVERY NOW AND THEN FOR CALLS. MY INFORMATION MAY NOT BE ACCURATE AND PURELY BASED ON PREVIOUS USES OF DIFFERENT DEVICES FROM DIFFERENT BRANDS.
THIS MAY BE DISREGARDED OR/AND DELETED
Today my sister nexus 5 (aosp 5.1 "newest") was "stolen".
We spent the day looking all over the place for it and went back to a few stores we visited that day and asked the staff. But it was of no hope. No one has seen or heard of it, so we regarded it as stolen. So after awhile we went home we went to ADM (https://www.google.co.uk/android/devicemanager) and set up a lock and number to call as you would.
After a few hours my dad found it in his car :/ so yeah...
But that's just the bread of it. HERE is the butter:
1)The lock we set up was 100% not in place even tho ADM said it was "sent". AND the mobile data is ON, but this is just how ADM works and it doesn't check if the device receives it or not. Maybe google should add this feature.
BUT even after we got it back and connect to WIFI, the lock did NOT get put in place. Proving the phone does not check for any lock requests at screen unlock. But maybe because she already has a normal pincode in place and it couldn't over ride that :/
after that I took a interest in the security.
2)So i took a deeper look into the security and it flaw, and first off. EVEN locked I could access the status bar and turn on AIRPLANE MODE. This was without the password and I could turn on torch, wifi, mobile data ext off as well. The only thing I couldn't access was the "settings". But I had a great deal of control of the device's connectivity and from there a thief could make his way out without any calls or ANYTHING affecting him.
3)THIS was truly shocking. I'm not sure if this is by default or by accident. But by using the status bar "exploit" i was able to get into the users page and switch to guest mode. From there i was able to grant adb access and access the market. If this phone was rooted I guess you could install some apps to get rid of the lock screen or even install a custom recovery. But them i guess it's up to you to take the action.
As i said before. I do not use it. My sister does. But she does not root or mod, and only follows the AOSP path.
Some exploits may only work because of a few careless button presses. And may not even affect anyone at all if you don't spam the settings with random presses.
Thanks for listening to me and feel free to point out any mistakes i made and share if you could post if these "exploits" work for you. If someone already made a thread please delete this one. Thanks for listening

Actually the only serious thing is the guest mode option.. About the airplane mode, for a thief it would be much easier to simply turn the phone off.. Anyway I completely agree with you.. Google should take more seriously the security part.. It should even be impossible to turn off the phone without a code..

And make the back impossible to open so a thief can't pop out the battery.
Once a phone is out of your physical control, consider everything on it to be compromised, regardless of whatever security you have.

Please delete this. None of this is news or exploits. People have known and been disappointed by it from day 1 of Lollipop going live.

Well removing the battery of the n5 is not immediate.. If a thief want to resell it probably he won't do that until he's at home or wherever and if he couldn't turn it off you could track the position or at least erase your data..

You say Google should take security more seriously. Take that advice. Never assume a thief would act in a manner that accommodates you.

That's right.. Anyway I should try to make his life as complicated as possible ?

It should even be impossible to turn off the phone without a code..

with some aluminium fold will easily to block any signal, the phone will eventually turn off.
p.s. If I am the thief which stole a useless phone, I will just break it and throw away. I don't think any thief will say "hey, I can't unlock it, let's return to the owner"

HELP : Phone asking for PIN instead of Fingerprints after MarshMallow update.

Hi,
I'm in need of help urgently!
Last week I had updated my Note 5 to MarshMallow and it was working fine. I remember the phone had never been off or restarted after the update until today when the battery ran out. Connected to charger and when I turned on the mobile it showed this message :
"Enter PIN instead of using fingerprint recognition after restarting device to protect fingerprints"
Now I've been unlocking screen using fingerprints from the time I got this phone. Unfortunately, I forgot the PIN and now I can't use fingerprints to unlock the screen. After a few failed attempts the wait time keeps increasing and now it has reached 30 minutes.
Is there anyway I can unlock my phone?
Please help ASAP!

Login into this website using your Samsung account
findmymobile.samsung.com/mindex.jsp
Find "Unlock my device" section
And make sure your device is connected to the internet then unlock you device

On the MM build, after a reboot you have to use the pin but subsequent times will be fingerprint, I have no idea why they did this. Sorry that happened to you, I have no idea how to get around that other than to keep searching, someone else had had that happen I'm sure.

Yep, I'm screwed, too...
I even kept a list of every iteration of PIN numbers I would ever use (they are generated by an algorithm). I have tried every one - and I am still locked out - with 60 minutes in between tries!
I have very, very important legal documents, notes, and recordings on my phone that I didn't get to backup yet. Unfortunately, most backups do not "dig" well enough under App directories to get all files generated by all Apps. So sad...
And "No", I can't access any sdcard or SIM bc it's an S6 edge+, and they are all locked into the case! The supposed Samsung "unlock" feature does not work, though it says it does.
Dying here! HELP...

You're screwed really and this is why a lot of devs on here say to make backups! Your only option at this point is a firmware reinstall..

But without root, I can't find a backup that will catch all the files well nested under App directories. With root, there are too many "gotchas" nowadays.
Besides, I know I have tried every PIN I would have ever set - so this MM "PIN" is a joke! There should have been a warning, as this is a serious disruption of service.
Wiping is just not an option - I have files created Friday, before the Upgrade, which would not have gotten backed up anyway. Besides, No update should block data access. One of you Gurus can't think of a workaround or push Samsung or Google for a fix? I'm thinking more like "Class Action Lawsuit" for disrupting normal access to my data and my lawsuit...
Anyone else that pissed?

You need to learn to "manually" back your stuff up yourself and don't rely on any programs/apps to do it...
There's seriously nothing the dev community could do because for 1 it's not the right way to go about this because if someone's phone is stolen or whatever basically they'd be able to come to XDA-Developers and find a way around the phone being locked for 2 that's definitely not what devs do, we don't look for ways to break into a phone or circumvent the security. You should have backed up anything you knew was important, simple as that .. You need to factory reset at this point. Sorry.

UNKNOWN SOURCES keep's turning itself off...? Anyway to make it stay enabled?

Not sure why, but a friend has a S8+ tmobile and the install from unknown sources ALWAYS turns itself back to OFF....? Is there some trick to making it stay enabled?

I'm pretty sure it's happening to everyone. Feel like it's their way of saying repeatedly that they would rather you not sideload apps that you probably got for free instead of paying haha. I've done research on this as well as its more of an annoyance. Most likely will have to wait for root

Yep happens on mine also

Yup, here too. Waiting for root sucks! Hopefully something will be verified soon. You guys should really google "SM-N950U root and you'll find a slew of root methods, I'm just too scared to try them. I wish they would just say error and nothing happens rather than have the potential to brick your phone. Oh well, waiting it is.

Trust me, as a dev myself, you dont want to listen to those. They have been tried already. And if they worked, it would be posted all over here as all the s8's on each carrier are the same phone. We are all working diligently to figure it out.
Except me right now. I'm at the doctor refilling my adderall so I can binge work on it all weekend hah

Haha yup I hear you. Thanks for your help on this. Keep healthy bro!

Well I'm sorry the unknown sources not sticking is a real thing... but I'm glad its not just her phone. I was convinced something was wrong and almost reflashed the firmware just because.... but it's obviously that way for whatever the reason. You just have to turn it on before each install I suppose. No big deal.
As for root, the eng boot was leaked or developed or whatever you want to call it... bottom line its in the wild now, so I think sooner rather than later there will be at least a eng boot type of root. Nothing compares to a real unlocked bootloader. *IF* I get a Samsung again, it will be the Exynos ###F model with a unlocked bootloader... But I'm a flashaholic....... otherwise ROOTING is becoming like jailbreaking is for the iPhone (non-existent).... at least for us USA owners anyway

I had this issue at first. This is my first Samsung phone since the Note 3. I thought it was something to do with KNOX. But after a week, I reset my phone, set it up as usual. And now the unknown stays. I can't recall what I did different, but I know wiping it did something.

It's a bug. Should be corrected with a future update.

From what I've done, I believe it's actually Google turning it back on with the feature in settings, verify apps. Just turn it off and it shouldn't turn off the untrusted sources anymore. Since turning it off, I haven't had issues

I think that did the trick for me. I had thought I already turned that off but it came back. Once I disabled that though my unknown sources has stayed at least for a few hours now and through me installing some stuff.
EDIT: there it goes back off again! doesn't seem to be anything we can do

How were you able to change the navigation bar icon colors from the default white to green on your sm-N950?

I have turned ON "UNKNOWN SOURCES" on my phone 2-3 days ago and it is still on.

Anyone still having this problem?

What about the built in security app lookout, I have that and the google play verify off and have never had the developer option turn its self off I think it may be that app blocking harmful apps that we want to sideload by keeping that turned off maybe lol:good::highfive::goodI have had mine on since about mid sept. when i got the phone)

How do I require pin at startup

I have a Pixel 4 XL and just like I had on the Note 8 I would like to require a pin at startup. I know the phones encrypted already but I would like that extra layer of security. Does anyone know if such a thing exists on my Pixel 4 XL and could you point me in the right direction please. I've been looking everywhere on settings and I can't find it if it's there. Thanks in advance for any help I can get.

Do you mean in addition to face unlock, you also want a pin to unlock the screen? Or do you just want a PIN to unlock the screen? I don't think the first question is possible without and app or mod. The second one would just require you to not use face unlock, and use a PIN/pattern instead. Hope I explained that clear enough :good:

Settings > Security > Screen Lock
from there select PIN and set any of the other options you desire.
after doing so, the phone will require PIN on reboot or start up.

I believe you need to have a locked bootloader and the phone be encrypted for that option to appear after setting pin/pattern/password lock option. I could be wrong and this could be completely removed for this phone. I unlock bootloader day 1 but I don't see the option

You get a prompt on that phone before the lock screen and android boot? Pin after reboot is there and requires you apply the pin/pattern/password after the phone restarts but that's AT the lock screen and not BEFORE it.
Edit: booted up my recently wiped 2xl and the option isn't there in settings either. I think you're referencing pin after reboot to get through the lock screen, which exists. I'm talking about pin to boot the phone, which is before android even boots up.

Yes it is. The new encryption works the following way, if you have your device powered off:
Secure-Start on Stock Android is default ever since the Android 10 update. It can't be deactivate, thus no longer be activated manually.
Until the lock screen appears on pixel 4/4XL, the device simply boots the stock system partition without loading user data, since Android 10 uses a more recent technology for encryption.
If the PIN is then entered on the lock screen, the user data is decrypted, and only then. If you have many apps and/or folders on the home screen of the Launcher, this is especially noticeable, because the first login and building of the home screen then takes much longer than on older Android versions.
There may still be OEMs that change this specific new Android behavior. This is very stupid IMHO. Because if an OEM deliberately disables secure-start as default setting and lets the user decide, it leads to confusion. Just think about it, if a user reads the above change and thinks "oh my device is already in that mode", he wouldn't even look for this option to enable it and run unencrypted.

PIN on booting phone is where you set a SIM PIN so the SIM has to be unlocked on boot.

Greetings. I have a similar problem. My phone starts everything every time I turn it on. All network connections are active. GSM, WIFI, Bluetooth. The pc connection also works! I don't want to enter a sim pin code! There is currently an incoming call even if I do not enter the unlock code. So the phone works on its own without permission! I want the phone to do nothing until I enter the pin code. This is currently just a screen lock, I switch any form. There is no obstacle protection. You can answer a call after stealing your phone! All you need is another sim card. This is not security! My phone Honor 20 is independent. Thanks for the help!

Question i just changed my pattern lock on my s21 ultra and forgot it. help please!

omg.
my friend just seen my pattern when i unlocked my phone so i decided to change my pattern (it had been a real long time since i changed it anyway) so i did it.
i cant remember what i changed it to.
i actually changed it 2x but the first pattern i thought was too easy so i changed it again.
i didnt make it any harder as in more dots to complete the pattern but hard enough i dont remember it.
im on a s21 ultra of course.
is there a limit on how many failed attempts i can do?
so far i think im under 10 but it does make me wait 30secs alot.
if there is an unlimited amount i think i will guess it but if there is a finite i dont want to mess it up and do a factory reset or erase.
i have alot of my grandbabies pics and videos on there.
if there is a way to bypass it please tell me.
i know my google acct on computer etc... thats not a problem and that is the same acct on my phone.

unless you have an unlocked bootloader I don't know that there's anything that can be done. I would just get them all wrong at this point and see if it let's you reset it with a good account. If you BL is unlocked you could boot into a custom recovery and wipe the security file.

Well, at this point you probably need to reset the phone, as you didn't link your Samsung account.
There actually isn't any way to recover the data Unless you can guess the pattern again.
I don't know if Samsung themselves would unlock the phone if you took it to the support center providing proof that you own the phone, but that could get your data back idk
In my opinion it is worth a try in this case

so far i think im under 10 but it does make me wait 30secs alot.
if there is an unlimited amount i think i will guess it but if there is a finite i dont want to mess it up and do a factory reset or erase.
i have alot of my grandbabies pics and videos on there.
if there is a way to bypass it please tell me.
i know my google acct on computer etc... thats not a problem and that is the same acct on my phone.

Your only solution is too wipe your phone. So take better care next time and chalk this one up to experience

Probably 3 then a waiting time, but it's probably more easier to take it to Samsung and get them to unlock it for you, since you own the phone they can do it.

i live in the country. i dont think there is a samsung store even in my state. im in iowa in usa

Samsung can't unlock it... pretty sure.
Once you set a lock screen the security is very good, too good. Sleep on it to see if the pattern comes to you... you still remember it.
That failing, suck it up. It may have not been your fault at all, see below.
I never set a screen lock, 2x tap on/off.
Never set a a bios password.
And most importantly never encrypt data backup hdds, etc.
You are the one most likely to get locked out... lesson learned the hard way.
A firmware failure, or external forces beyond your control (high energy particles of cosmic origin can do it*) can put you in a no win situation once you set an eccess password. While if you hadn't you likely wouldn't be locked out. I had a laptop bios lock me out, the password was simple a simple "S" even years latter I remember it... but the bios doesn't!
*this isn't a joke. Flying or being at higher elevations increases the risk. While it is slight when under the protection of the ionosphere it's still a random failure factor. One high energy particle can change the value of a flash memory cell without damaging it. The data however is corrupted unless redundantly backup which is one reason why spacecraft use at least 3 redundant computers.

omg wut ._.

Even if u hard reset, u will be asked to input your Samsung account and password, anf even with out knowing the pattern you have the option of putting in your PIN.
If you don't know your own PIN code then, something Is wrong!
