Hi! I have an S7edge with full encryption enabled with a password. My phone was acting slow and firefox was not being responsive, so I power cycled it. It came back to the normal black screen with "Your phone is encrypted for security. To start up your device, enter your password." I entered in my normal password, but it was rejected. I tried this several times, which resulted in a message asking me to restart my phone. I thought that this was odd, since I changed the setting to never wipe, but instead just lock out for an increasing amount of time. After a few iterations of this, I'm at the 7 attempts left until a full data wipe.
I'm thoroughly confused as to
1. How my password is no longer working?
2. How the setting for lock out time vs. data wipe was reset?
Is there any way to solve this issue, or I'm out of luck and will need to perform a full data reset?

I know that Encryption issues have been discussed in the forum previously, and I have tried the various methods to encrypt / decrypt my OnePlus but its extremely flakey and I end up eventually losing my data and wifi until I flash the stock userdata image.
I have tried on a completely fresh and clean install.
As advised in another thread (OnePlus Forum), I don't set up wifi or google account and make no changes except to enable encryption.
As advised, I dont touch the phone for 5 - 10 minutes after encryption reboot before entering decrypt password.
Some of the time, after waiting the 5 minutes to enter my password, the robot appears quickly, the phone will stall for a min or two (led notification light functional and capacitive keys are lit) and then come to life.
More often than not, after entering my password, the phone just dies. No lights and capacitive buttons are dead. It takes a hard reboot to get the device to power up again and when it does, my data is gone.
It doesnt matter what ROM (AOSP or CM11/s) or Kernel I use, I am not getting consistent encryption. The wait for phone reboot is incredibly long and terrifying as I dont know if my data will be intact.
Not to mention this happens on TWO different OnePlus... One with build date in July and the other has a October build date.

Didn't know about the encryption issues and lost all my data yesterday m(
Anyone with a solution?
Would really like to know my data to be secure in case the phone gets stolen/lost/confiscated/...
Data is "Safe" in case of loss or theft because its encrypted.
Data is "Not Safe" bc the device decides to corrupt itself.
The problem, I believe, is the lack of any status/feedback once you input your pin/password. The screen goes blank. On a nexus device, the screen shows the boot animations after entering Pin and thereby giving feedback.
Its been my observation that any interruption in the boot process will corrupt the device and you will lose your data.
By advice, be extremely... EXTREMELY patient when the screen goes black and just wait for it to come back alive.
A good example... I switched to ART after encryption. It look the device about 20 mins to rebuild cache. But again, there is no status/feedback to let you know it's rebuilding the cache as there is without encryption.
I believe the new OTA 44S is addressing data corruption in an unused partition. Maybe this will help with encryption corruption.
Already running 44S. At least I lost all data...
Thank you very much for your explanation.
I think, I'll wait for now and maybe all of us could contact 1+1 support...?
one dead
On 44s i activated encryption. After 1 hour it was done, waiting 10 minutes after reboot to enter pin. After that the androiod starts with the language question, so all data is gone. But after 2 seconds it reboots, ending up in a loop. Tryed to start recovery, but there seems to be no recovery, only the one plus icon comes up.......
I hope i can get it back to life.
I did a factory reset on my S7 today to fix some strange notification reminder errors, and found out that my home button no longer likes to let me register my fingerprints. The button was working fine to unlock the device today before the factory reset, and I've already attempted the clear cache partition method to get it working again. Any time I attempt to register my fingerprints, it simply says "Make sure that the Home key is clean and dry, then try again." I assume this is due to the fact that the home button got scratched a couple of months ago, but again, it was working just fine with the scratch up until I lost my fingerprint profile.
So, is there any way (including if I have to root it) to "sideload" a fingerprint profile or suppress the "Make sure that the Home key is clean and dry" message when setting up fingerprints?
Thanks
Fingerprints are stored securely by the TEE, so there is no way to sideload, not on official firmware at least. The message you see about wiping the button is also hardware initiated. It should display in any situation where a scan is done, not just when registering. So something happened to the physical scanner at some point. I'd recommend just sending it in if you dont manage to fix it yourself.
It was hot. I don't think the phone was necessarily feeling the heat like me... but... the way it was acting... maybe so?
The second to last day of my vacation at Walt Disney World (first time!), my S8+ started acting wonky. I tried to take pictures and the application wouldn't work right.
So, I rebooted.
Now, I'm staring at a screen with a textbox at the bottom of the screen and some text near it (I don't recall it verbatim) "Enter your emergency password".
What? What's an emergency password? Typing in the textbox, it was obvious that it wasn't a numeric-only textbox (for PINs) but it was alpha-numeric. I simply don't recall registering anything but a pin and my fingerprints.
Freaking out, I kept trying to restart and worked with the power and volume buttons.
All I continued to see was the Samsung logo.
Suddenly, I got a black screen with text telling me things were being erased. I then see a blue screen with an android bot telling me stuff was being erased.
After a bit, I was back at the language selection.
Gone. Pictures. Data. SSD... entire phone... fully erased. (Thankfully, a majority of my pictures were immediately put into Instagram... the lost pictures I used the phone's camera app because it works better than the Instagram camera).
Don't have my laptop... so I don't have my password database, so I cannot get into ANY applications.
I know there are requirements for Microsoft Exchange, and other applications that require special security for being a device administrator... I'm not aware of Exchange requiring a password for the phone but... who knows? I didn't enter the password wrong too many times.... even as hot as it was I still used my print to unlock the phone.
Man, that is horrible. My condolences. If you can boot the phone into recovery mode (Hold down volume up, then the Bixby button & then the power button...all at once). Once in recovery, do a factory reset and you shouldn't have to enter that 'Emergency Password'. Unfortunately, everything is lost unless you ran a backup into the cloud or on your 'puter.
Sorry for the post if you've already reset the phone as it sounds like you might have since you mentioned the language screen.

Yeah I didn't have the choice -- the phone decided to reset to a fresh install point. Once I got back home I restored to a previous backup after trying everything I could to undelete stuff on my SDCARD.... but none of the software I tried would work... kudos Samsung... your deletion of my SDCARD was VERY complete...
Did you have the SDCard stand alone or merged with the internal storage? I'm surprised that got wiped also.

The only reason I see for this to happen is if on the "lock Screen and Security", inside the "Secure Lock Settings" have enabled the "Auto factory reset".
Biometrics won't trigger a device wipe, they will only force the pin/password field on too many attempts.
You say Exchange. Is this a corporate account? Is there a possibility that someone remotely wiped your device? Log into OWA (the web interface of your Exchange), navigate to Options -> See All Options, then click the Phone tab and see if a wipe was sent to it. Because what you described sounds a lot like a remote wipe. (Though I've never seen the emergency password field.)
Also make sure that you're not violating your corporate policies. Granting admin access to the Exchange app gives your company full control over your device. They can see you accessing your email with it, and if you're doing something that you shouldn't be, they will wipe your device.

No way of knowing but I don't recall ever setting that (I wouldn't).
something corrupted your ROM it sounds like, somehow!
if it was the red box that says like "enter password" I believe it is actually "default_password"
My phone is Samsung Galaxy Note10 Lite (Android 12, One UI 4.1).
The device was working normally before I put it in my suitcase with many other phones without protection. After a while I took the Note10 Lite out and saw the wallpaper had changed to default like when I activated the phone the first time. A "Safe mode" text also appeared in the lower left corner of the screen.
I unlocked the device using password and it took me to the process looked exactly like a factory reset with Language/Region options and privacy settings to choose. I followed all of these steps.
After the "factory reset alike" was done, my 3rd apps were all gone, only system apps were kept. I opened Settings>Apps and no longer saw 3rd apps in apps list. I moved through the internal storage and noticed 15gb of data was loss. The strange thing is my media files (musics, videos,...) and documents are still intact, nothing has been deleted.
I tried to restart the system, also press the "turn off Safe mode" notification but it always show an error message when the phone boot up:
"Phone started in Safe mode. There's a problem that's preventing your phone from starting normally. You'll need to factory reset your phone to exit Safe mode. you can use Safe mode to back up your data to a computer or SD card before resetting your phone."
As far as I know, phone which turns into Safe mode isn't supposed to do a factory reset automatically. Does anyone know what problem am I facing with? I don't want to do a factory reset as the message said, because there are apps contain important data which will be lost if I reinstall them.
Booting into Safe Mode DOES NOT FACTORY RESET Android OS:

It's my GF's, and she uses a pattern unlock along with fingerprint. No new apps were installed or settings changed that she recalls.
Began as phone locking immediately after correct pattern was entered, but using fingerprint would unlock correctly.
With this immediate locking, the phone will by itself turn off the screen then turn it back on for two seconds as though the power button was pressed, then turns the screen off again.
When entering incorrect pattern, it says incorrect pattern and does nothing else.
She tried restarting the phone, which disabled the fingerprint unlock feature until the phone is successfully unlocked once.
Phone still locks immediately after entering correct pattern, and now she can't unlock it using fingerprint.
Now unable to unlock phone.
EDIT: If I repeatedly enter the correct pattern, after a random number of tries it will go to the 'starting phone' screen, but then will either restart by itself or sit there until I restart the phone. It really is random, once it took 7 tries, another time 20 tries. The phone doesn't show up on my windows PC as a mounted device during any of this.
USB debugging was not enabled, so I don't believe I can run any ADB commands. She didn't backup her phone and our focus is at least to get the photos off the camera, at which point doing a factory reset would be acceptable.
I've tried:
Entering a lot of bad patterns, trying to get to an option of unlocking with the google account associated with the phone, but the option never comes up.
Removing the phone case, only external item on the phone now is the stock screen protector.
Starting into recovery, clearing cache, repairing apps.
Starting into safe mode.
Booting in and out of root.
Letting the battery discharge completely to do a hard power cycle.
But no luck. The phone still locks immediately after entering the correct pattern. I haven't tried taking the phone's stock screen protector off, but will probably do that in case there is something wrong with the proximity sensor.
This is the international two SIM version of the Note 10, the only Note 10 variant which was rootable. I haven't worked on the phone for at least a year since it was rooted and setup.
SEU or a hardware failure. Either way when this happens your only option is to backdoor in. If it was a SEU after resetting you're good to go. If hardware it will likely reoccur... Even with a hardware failure many times nothing happens if no lock is set, you still have access. Setting a lock password introduces added failure modes.
SEU's are very rare but they do happen, randomly and just one bit of data is flipped. Interesting they cause no hardware damage. Higher altitudes elevate the risk as does exposure to man made high energy particles. That's one reason why spacecraft have 3 or more redundant computers. Apollo fights have logged half dozen or more SEU's per flight.
I never screen lock my N10+'s, double tap on/off. This is one reason why. Same with PC bios, no password is ever set. Once bitten, twice shy as the user is always the most likely person to get locked out... as I learned the hard way
@blackhawk, I hear you on getting burned with device security. And for any electronic device, secured or not, backups and redundancy are the only reliable difference between your device being useful and useless. It's been hard not to say any 'I told you so' about this, since I was telling her both to use a pin instead of pattern and to let me setup a regular backup. I don't know that a pin would have been different, but I think it would have since the fingerprint was working before the restart.
Do you have any resources you could point me to on how to backdoor into an android with a password/encryption? I know you can unlock a device using ADB, but I believe you need USB debugging enabled first and I don't know how to make that happen without first unlocking the phone.

Samsung repair can do it. A local shop or yourself, maybe. If there's an associated Samsung or Google account, start there. I never had to do that but the information isn't hard to find. The data will likely be lost though.
Meh, it's a very rude surprise.
