You may want to think twice before updating your Galaxy smartphone for now

Multiple reports are coming in concerning the Galaxy S7, the Galaxy S6, the Galaxy Note 5 and even the Galaxy Note 4. It appears people who are updating their devices to Marshmallow for the first time just now are facing an issue related to passwords and fingerprints, in that once the update is installed neither the password nor the fingerprint is being accepted. It doesn’t appear to be affecting all users so you may or may not have experienced this, but it appears to be widespread enough to generate some buzz online.

The easiest way to ensure that this doesn’t affect you is to remove the password and fingerprint login before installing the update. If you are locked out and your device isn’t accepting your password just go over to findmymobile.samsung.com, lock and then unlock your phone. You do need to have a Samsung account associated with your device if this method is to work, if you don’t have a Samsung account and have been locked out then you’ll probably have to take up your case with Samsung customer support.

It’s believed that this issue might be partly caused by encryption being turned on by default in handsets with a certain level of specifications. Unless the feature is turned off, users have to enter a pattern unlock, password, or pin code every time the device is booted up. It’s this feature that’s apparently distorted stored passwords and fingerprints, thus locking users out. There have been reports of this issue appearing on Android handsets from other manufacturers as well, which won’t be surprising since it has more to do with the Android update and less with how Samsung implements device unlocks in its handsets.

Samsung hasn’t commented on the matter yet. We’ll keep an ear to the ground and update you when there’s more information about this issue.

Problem on my wifes S7 Edge after June security update is that circles no longer works at all and also secret mode will not work for he with either pin or fingerprint. And she is not the only one. I’ve talked to others with the same problem. Is it related to this? Maybe it’s a problem worth checking out and finding out if anyone else has the same issue. She doesn’t use either options so much so it isn’t a big problem, however it should be adressed.

FIXED here. 🙂

Yesterday I OTA-updated my Galaxy S6 to G920FXXU3DPDP (Dutch T-Mobile, unlocked).

I disabled unlocking through fingerprints (thus erasing them), then entered a new fingerprint, and re-enabled unlocking through it.

I may have done it wrong until now, but the process has changed (for the far better).
Now it is: casually pressing the Home button with the recorded thumb, then swiping the screen. (It has become as swift, though different, as on my iPhone 6 – restoring the competitiveness of the S6.)

Now I’m scared.
Before, I was excited waiting for my Note4 to have the ‘off screen memo’

Do it but take no chances and also do a factory reset before downloading the update and after if possible.
I didn’t do it with lollipop 5.1.1 and I had small issues like music app occasionally crashing but I decided to not take any chances this time. It’s a hassle but worth it. Back up all your data first. Apart from this small issue of having to type a backup password when I wake up the phone before using the fingerprint scanner everything else is flawless and better now (knock on wood). More reliable fingerprint scanner and faster performance in general.

Updated TabS2 to MM with no issues. Fingerprint was used for lock screen, with backup password and device was encrypted. During or right after the upgrade MM informs you that the finger print lock screen needs an extra backup password, so you’ll just have to set that one as well.

The fingerprint lock screen itself has changed: it immediately allows entry of that extra password, but if you just put your finger on the fingerprint sensor, it unlocks as before.

it seems that not everyone is affected and I doubt that someone knows what the exact reason is.
And till now I only read about problems on smartphones…strange

same issue with my Galaxy s5 after Marshmallow update.. Doesn’t recognise fingerprint but instead have to enter backup password to gain access

At least it is behaving quite strange here on my Note 4 (not encrypted) and it seems like Samsung hasn’t implemented the Fingerprint API propperly. For me, only the fingerprint functions that worked in L are working in M…except the mentioned Fingerprint on lock screen (I get asked “Enter a backup password.”, wenn I enter one, it just says “Sorry, try again” without saying why it failed), even after going to security settings and deleting the credeintially, which fixed such problems on 5.1.1 it doesn’t work.). I also had read, that you could use your Fingerprint for authentication in PlayStore,… Read more »

Having the same issue for more than 3 weeks now. No third party unlock apps installed. Samsung Hungary does not have any solution at the moment except to try a factory reset.

Yep this is what has been happening to me since day one. It was a little bit weird at the beginning but I’m now used to it. I thought it was an extra security level introduced with the update.

It’s already a problem for over a month now and the problem only exist in devices that have 3rd party app for lock/unlock solutions like apps that emulates tap to wake, gestures etc etc to wake the screen. The workaround is to uninstall those 3rd party lock/unlock apps.

It’s been made public that it’s not just Samsung devices. It is a conflict between different security methods in stock and TouchWiz and other OEM security software.

How can it affect the S7 when it launched with MM; please fact check before posting next time.

Yup, says it right on the screen when you setup fingerprint lock. Backup pattern, pin, or password will be needed if you restart the device (which happens when you update) or if the device has not been used for 24 hours.

Hello ,
I have a “note 5 n920s”. Of course update it into marshmallow from lollipop. I did hard reset and my problem is that it is asking “password” instead of going to language selection screen. Still shows a screen with “call me button, Enter password and emergency call button”.

I have done
1. Factory reset
2. Flash through odin
3. Downgrade through odin

But nothing works for me it still shows a screen with “call me button , Enter password and emergency call button”.
Any help please

I think in your case you need to enter your Samsung account password

Marshmallow will ask for the backup password if you use fingerprint lock in certain situations. Seems more that people forgot the backup password created for the lock screen. I believe simply rebooting the device will require the backup password before you can use fingerprints again.

Gotta love stories that use Reddit as the source.

Luckily I’m in the USA and AT&T is my carrier, so I don’t have to worry about upgrading to marshmallow.

I think some US carriers deleted the fingerprints as part of the update in order to prevent this.
