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.
I am facing difficulty on my PK1 deodexed rom while trying to unlock the screen. After swiping my finger, ut won't unlock and won't give any reason, just stuck. When i try using the backup password, keyboard won't come up for me to type my password until i lock/unlock with power button and change my keyboard back and forth multiple times before working.
I have checked for possible solution online, cleared cache and wiped data on both app manager and Titanium backup app.
Please any information will be gladly appreciated.
Thanks
Solved!!!
I was able to solve it after troubleshootibg by myself.
Found out its peel remote notification causing it. On the lock screen, the remote icon is always visible and accessible. I turned off its notification and viola, fingerprint and password now working as they should.
Hi, my fingerprint not working after unlocking bootloader, when i restart the phone he work, but after sometime appear "fingerprint hardware not available", and not work more.
I really need a help.
My phone is E6683.
Hello, I had just flashed the firmware on this demo store unit (G900VM, originally G902V) from a liquidator. Surprisingly mobile data works but the fingerprint scanner is not accepting any. In the menu to add prints it notices the touch and turns green, but does not go any farther than that. Did not bootload and unable to enter service menu due to no IMEI. Thanks in advance

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.
