[Q] How to unlock the screen with fingerprint?

My Samsung S5 (SM-G900F, 4.4) device has a fingerprint scanner to unlock the screen. It was working perfectly, but now it only asks for the alternative password, but I forgot it. I tried on the Google webpage to lock my phone, I hoped that the password given there will be overwrite the alternative password on the phone, but it said, that it found the phone already locked, so no need to use the password. I don't want to do a factory reset if it possible, how could I get the fingerprint scanner to be an option again, or somehow unlock the screen and use my phone?

This happened to me today in the morning on my S5 mini with stock OS. At first I typed in the correct alternative password, but it was not recognized. Latter I successfully (?) changed password with "Lock" option on Android Device Manager, and it didn't help either...
At the end I did a factory reset and lost all my data
Is this a common bug? Should we report it somewhere or something?

After too many failed fingerprint attempts, it will only ask for the password
Maybe someone else has been trying to access your phone
Factory reset to regain access if you don't know your alternative password (Probably a good idea to write that down)

Yes, you are correct. I tested this again, and I think that, in the morning, I really used wrong password . And the first time I didn't notice the displayed info, about password already being set, on Android Device Manager site, when I tried to change the password.
Thanks for the replay

Sold Nexus 6p

I sold a nexus 6p online. I shipped it out to the buyer. He received it and he is unable to sign into his account on the phone. It is telling him that it's still attached to my account. I was wondering if there was a way to remotely delete my account so the buyer and sign into it with his account.

Search google for FRP (factory reset protection).
As far as I know there is no way to do it remotely. I think you should have signed out of your google account before you reset the phone. Most likely he will have to ship it back to you so you can sign in and then remove your account.

Here: https://security.google.com/settings/security/activity?pli=1
But I'm not sure how that will affect the device.
You could always change your password to something stupid for a few seconds for him to sign in and sign out depends how sensitive data you have on your account..

Will Android device manager do it? Will it remotely wipe the phone and remove my account from it, or will it flag the phone as stolen. I cannot get any solid information from repeated Google searches as to what happens after the device is remote wiped.

Android Manager will wipe the device but when it turns on it will ask for any Google account it was bound to before wipe. The other person needs to enter your Gmail account, then his, then you can either change password to your account or wipe it with Device Manager and next time it boots it will accept your account or his (because both were added before wipe).

You can always set a temporary password to your Google account, send it to the buyer and have him log in with his account. After that, you change your password back and voilà.

Is all of this a working protection against simply Fastboot unlocking bootloader, flashing stock image then rebooting into a working phone?

If the bootloader is currently locked, I believe you would have to go into developer options to enable the OEM unlocking setting... Which you can't get to because of the FRP.

Unlocking bootloader (OEM unlocking in dev options) deactivates this protection but to do it you still need to get in there somehow and you can't without first logging into a Google account it is currently bound to. And as you probably know without unlocked bootloader you can't flash anything.
And even if he could flash new ROM my friend had bought used Samsung S7 Edge and previous owner also left it locked. You can flash different ROMs with S7 Edge out of the box but the FRP survived several attempts at flashing stock/custom ROMs. We had to use the workaround found here at xda S7 forums.

Thanks for all the info.
I did not unlock the bootloader on the phone. I read a little bit about Factory Reset Protection and the only way around it was to sign in to the phone and then remove your account from the phone. It's something that was new this year for Android devices and I was just unaware of it.

It's actually been around awhile, just not widely implemented. If you remember which monthly security update you last installed, he might be able to get around it. YouTuber root ninja has some videos depending on patch. The one I watched just for kicks (since I'd like my 6P to be protected if lost) was a few months old though.

I heard that with a simple factory reset with the stock recovery should remove the account from the phone.

Lol good luck with getting that off remotely it's impossible it's kinda like apple cloud system which is really good.

Forgot Pattern

Trying to help out a family member. She setup a pattern on her phone and forgot it....
Google search returns "dr.fone" but when installed it only shows options till GS3 IIRC
Samsung find my mobile doesn't help as location is off
She has no backup and doesn't sync with Google Photos.
Any idea how to remove the pattern and retain the data?

Pattern/Pin

Hey guys
Im in a bit of a trouble.
Sitting in front of my dads phone trying to unlock it.
Cant ask my dad anymore. He died few days ago. To get access to his password safe i really need to unlock the phone. He stored all of his onlinebanking accounts, insurance data and stuff there. Need to pays all his debts but i have no clue about what to pay and what is paid.
Already found his secret note about the master password of keepass but not the unlock pattern.
Factory reset is of course not an option.
Any chance that i can skip the pattern and unlock it with the PIN?
Its also still connected to his google account if this would help.
Bootloader locked, no root, no twrp.
Found a thread from 2013 that says i can boot to twrp without flashing to delete the pin data but im not sure if it works on this one.

Can you access your dad Google account from a computer? if so, you can use Google Device Manager to remove the PIN/password of the device, but I'm not sure if doing this will erase the data. Also, you should contact Google for a solution, considering that isn't unauthorized access, and have a good reason behind. There is a form to contact them. Sorry for your loss.

Hi,
Thank you for your condolences.
I tried to lock the phone but it wont let me change the password.
There is a message. You already have a screenlock on the phone so it wont be changed.
The link you gave me also only let me get access to the account but not the phone.
Any other ideas how to get access?

This device was reset. To continue, sign in with a google account that was previously synced on thos device.

Hello everyone,
I got a phone Galaxy A 20 and called Boost mobile to sim unlock the phone, what they did.
When done I factory reseted the phone. Now when I try to add an account I got a "your phone was factory reset., type the password to unlock it. If I bypass the request I get "This device was reset. To continue, sign in with a google account that was previously synced on those device."
I don't have those information, is there something I can to to really reset the phone and not get this message?
Thanks

This means that your phone has google lock, also known as FRP (someone forgot to log out from google account). It is possible to bypass it (i successfully did it on Lenovo Tab M10, Lenovo Tab 3 7 and Nokia 5.1 Plus), but sometimes it can be difficult. According to this video, you can enter settings by crashing the setup wizard app. I think installing Apex Launcher is unnecessary, you can search for the Pin Windows feature. I didn't tested it, but I think this should work.

thanks you very much for your answer. Nothing worked for me because I couldn't have access to the launcher adn the settings. I brought the phone to a store and he was able to crack it
