Fingerprint While Screen is Off? - Samsung Galaxy S8+ Questions & Answers

My wife just got her S8+, and we were trying to get the fingerprint sensor too unlock to the home screen the way her pixel would. The way it works now, she has to awkwardly reach for the sensor, then swipe up to unlock the device. Any suggestions, or are we out of luck unless Samsung devices to make this a feature in an update?

Did you enable 'Fingerprint unlock' in the settings? I'm able to unlock my S8+ while the screen is off just by putting my finger over the scanner without swiping anything.

I'm not sure of this caused it, but we ran a system update and it started working as expected. Again it may be a coincidence, but it started working right after the update. Mods can delete this thread of they want, it's not a relevant question since it seems to have been a bug.

Yeah, same here

How is the fingerprint unlock supposed to work? On my Nexus 6P, with the screen off, you just put your finger over the sensor and the phone turned on, unlocked. But it seems the S8 requires you to push the power button, then use the fingerprint scanner. Is that correct? Is there a way to have the fingerprint sensor turn on the screen?
(Yes, I do have "fingerprint unlock" turned on in settings.)

I don't have to push my power button to get it to unlock. I just place my​ finger over the sensor with the screen off and it works instantly and doesn't show the lock screen.

Don't delete it, I almost gave up on this option, reading this made me try again and it's much improved, thanks!

Interesting. I'm not sure what I'm missing, but I can't get mine to do that.
Edit: I may have bigger problems. I can't actually get the phone to lock. I have smart lock turned off and only pattern selected for screen unlock type, but I can just swipe on the lock screen and go to the home screen, without entering the pattern. I assume these two issues are related.
Further edit: OK, the second issue was because of the "secured lock time" setting. So, unrelated.

Well, I got it to work. It actually was the "secured lock time" setting. Basically, if the phone isn't actually locked (because the time in that setting hasn't passed), even though the screen is off, the fingerprint sensor won't wake it. But if more than the set time has elapsed, it does.
Not the best design, but that explains it. My advice: set the secured lock time to zero ("instantly with the power key or when the screen times out").

Hmmn, I have mine lock instantly via power button and tried it... Still works for me

I didn't explain it well. Locking instantly is the way to go.
For some reason, it's set up to use biometrics only if the screen is locked, not just off.

Posted this before but with all the setting correct.
You can simply put your finger on the sensor and it will unlock right to the home screen.
You need to habe the finger print unlock turb on.

This has to be my favorite feature on this phone, beside using it to pull the notification bar down

Does it work on s7 edge?
Is there anyway so I can unlock my phone when it's off using fingerprints?

This is the S8+ forum. You would get a better response in the S7 Edge forums.

Potential fingerprint scanner issue?

I have a S7 from AT&T, non-edge. I have the lock screen setup with the fingerprint reader and a pin code.
95% of the time, the fingerprint scanner works the first time.
4% of the time, it will work the second time.
1% of the time, it does something VERY strange. If it fails the first and second time, it will NOT unlock the screen using the fingerprint reader unless i enter the pin code. It will let me keep trying my fingerprint, but it will says its not valid. I can enter the pin code, unlock the phone, relock, then boom, the fingerprint reader works again. Its like once it fails twice, even though the phone lets you keep trying, it doesn't really read it.
Has anyone else experienced this? It's very annoying and I am wondering if I should RMA, or if this is a software issue.
Finger print scanner indeed suck.. Just make multiple imprints of same finger.. Get every angle possible.
Only time I have to enter my pin is when I reboot the phone. It wants my pin instead of my fingerprint. After that first time though the fingerprint is all I have to do.
when entering a fingerprint each time change the angle of the chosen finger slightly as you press the home key having multiple images at diff angles lessens the chance of not getting a match.

This has taken some getting used to, coming from the Nexus 5x... its fingerprint scanner is so much better.
On the nexus, you go from a black locked screen straight to the home screen in a split sec with a touch of the scanner that's way more accurate and gets it 99% of the time .
With the S7, I'm having to press the power/home button, then scan, which gets it right more like 65% of the time. And is a 2 step process. Or hold the home button down and try to time it just right- too soon and it doesn't read.. too long and i open google now... haha too complicated. I'm almost thinking there's an issue with mine it's so inaccurate. Or maybe i'm just spoiled to the nexus...
Bottom line= LG & Google implementation= much much better.

Press and depress the home button quickly, but instead of taking your finger off the button immediately, keep it on there lightly touching for a split second. It's not that difficult.
It works for me on the first try 95% of the time. The other times it's my fault for not covering the button but instead getting just a corner of it.
I also set it up with both thumbs and both index fingers and it works with all. I'm quite pleased
I've been having aroung 50% success rate on the first time with the fingerprint scanner and about 95% on the second attempt. I don't know if I'm doing anything wrong. I've made the fingerprint profile many times, change position and angles but I still can't get it to work reliably. I wish i could see if theres any gaps, or maybe tone down how "strict" the scanner is.
I've found another flaw in the finger print reader... I'll describe the issue, then upload a vid to show it.
My screen is set to lock/dim/shut off after 30 seconds. At which time you'll have to press the home button OR power button to wake the phone, followed by using your finger print to open the phone.
However, within a few seconds of the screen shutting off you can just press the home button with any finger even ones you've never registered a print for and it will unlock the phone.

There is a setting, which by default locks the phone 5 seconds after the screen turns off. During that time you can just push the button and no need to unlock.
But if you push the power button to turn the screen off, if locks immediately. There is a setting for that as well.
Yea...that's not a good thing. Should not be on by default.

It works 100% of the time for me if i press the home button and leave my finger on it. Its not even a tiny bit innacurate. Maybe your fingers are greasy.
The reading from screen off sounds a bit better but is essentially the same thing. Just on S7 you have to actually press the button down rather than just press the finger on the sensor. Im not sure why the added pressure makes it that much worse.

No it shouldnt be on by default. Its a great feature, if you dont like it you turn it off.

That's an android thing. My previous LG and Motorola phones had the same settings by default.
It is convenient because if the screen turns off due to timeout while you are reading something you can quickly turn the screen back on without having to unlock it (password unlock can be very annoying). I gotta tell you if that feature didn't exist, I would have to set a really long screen timeout because I do quite a bit of reading where I don't touch the screen for a while and the constant need to unlock would drive me crazy.
Plus, an extra 5 seconds (added to the screen timeout) is unlikely to make it insecure. If you hit the power button to turn the screen off, it locks immediately. I think it's the best combo of convenience and security.
i'm just saying i feel like that goes against the "security" of having your phone.... your phone could get stolen while unlocked, and all they have to do is set your screen to never time out and now they have access to all your info...

I someone steals your phone, while it's unlocked, they already have access to all of your data. The 5 second delay isn't going to make a difference.

Getting pin/pattern on fingerprint unlock A LOT?

I know it asks for pin/pattern in certain instances like after reboot, when changing users, and after an extended period of time (like 48hrs), but I'm getting the pin screen like 75% of the time. Been like this since I got it. I've re-scanned my fingerprints.
Is the fingerprint scanner relegated to a novelty feature if it's almost always asking for your pin/pattern?
Anyone else getting it to this extent?

I get it sometimes but it's because I have tasker lock my screen when I unplug it from my car. Because it was locked by the "administrator" it requires a pin in addition to my fingerprint.

So having "power button instantly locks" under security/screen lock/settings counts as locked by administrator I assume?

It could be a haywire app. Power button instantly locks is not the reason, because mine is enabled.
I have had this happen to me a few times though... nowhere near 75%, but maybe 1 or 2 times a day with no explicable reason.
I've only used the phone for a day now, but I haven't had it ask for any additional unlock other than the print so far(besides the software update reboot). I'll update once I've used it for a bit longer.
Apparently it was 'power button instantly locks' because I've had no probs since I unchecked it. Just don't remember having that issue on other phones. It locks when you press the power button anyway so don't get the point of that feature.

It must be a system bug then, and I suggest you report it from your phone using the feedback/bug report function. I have "power button locks immediately" enabled and like I said, 99% of the time it works fine and unlocks with fingerprint. So it must just be a software bug.

HTC U11 Screen off without locking

I have an HTC U11, upgrading from the HTC ONE M9.
On the M9 I used a utility app called "Screen Off & Lock" which worked really well, since I wanted it to lock.
But on the U11, if you lock it, you can't turn it back on with just the finger print scanner. You have to also use your passcode to unlock.
I need an application that functions exactly like the sleep time expiring, so that the screen shuts off and is unlockable with the scanner and not the pin.
I've tried... a TON of different applications, many that claim to do this. None of them do this. They all lock the screen and the finger print scanner won't work until it's unlocked.
Anyone?
In essence, I need something that simulates the power button, which does NOT lock the screen. It just puts it to sleep.
Again, no luck with the dozen or so apps I've tried.

Still hoping for a solution.
Yes very annoying, I get the power button confused with my Vol - button all the time.
I bought Gravity Screen some time ago and it at least has an option for SmartLock and fingerprint readers. I'm testing it now. It works, but it isn't ideal as there are some bugs with the screen not waking fully or too long of a delay after the fingerprint is read correctly.
I'm not sure I'll keep it up and running, but it may be an option for you.

I might totally be misreading this, sorry if I am. But check in settings/security or lock screen and go to secure lock screen of you have that and see if those options fix it.
Going to hopefully bump this up, as this is still an issue.
As clearly as possible:
- On the HTC U11, if you hit the power button, you can unlock the phone with your fingerprint OR using your PIN.
- All of the screen-off utilities lock the phone and then require the PIN to unlock and will not respond to fingerprint.
- I do not want to disable or alter the security settings of the phone, since this is, obviously, already something the phone can do without changes.
Has anyone created a utility that works for the U11 yet?
For me, I'm using Nova Launcher with double tap to sleep. The remaining problem is that Nova launcher just turn the screen into black and navigation buttons is still functioning for the next 5 seconds. I have to wait for 5 seconds so that I can put it into my pocket. Otherwise, the screen can be accidentally turned on.

Fingerprint unlocks phone while in the pocket

Hello,
I've recently discovered that if you try and place a finger on the fingerprint sensor while the phone is in your pocket, the screen will successfully unlock, which I believe it's not normal behaviour. Every time I pull it out of my pocket the screen turns on and the phone unlocks, leaving it prone to accidental taps and inevitably open random apps every time.
Does anybody else have this issue?
I just tested it. Same here.
If I cover the sensors while the phone is just sitting there and then place my finger on the fingerprint reader - it registers it and unlocks the phone.
If the phone is unlocked and I cover the sensors - I get a message that the touch protection is active and it doesn't allow me to click on the screen.
Great "touch protection", Huawei. Good job on this one.

Yeah, it basically works only once the phone has already been unlocked, lol.
Nice addition to the stupid lock-screen notification issue we are having in the other thread. How awful.
At least I'm glad I'm not the only one, I'll try and open a chat when I have some spare time to waste...

OP 6 Automatically unlocks

Hi,
I have a problem with my OP6. I hae the latest OOS 5.1.11.
When I have the phone in my pocket, it's locked, than quite often when pulling out of the pocket I naturally grab it the way, that mu thumb is in the screen (I am not touching the fingerprint sensor) and when I take it out of the pocket, the screen unlocks itself.
Is this problem related to the issues people have posted regarding pocket mode not working and allowing to unlick with fingerprint while still in pocket or another bug or maybe hardware issue?
Thanks
face unlock??
No, its even before it's able to "see" my face. I just feel a small vibration under my finger and it unlocks. Also, for face unlock to be activated I would need to wake up the screen, but the problem is, it wakes up on it's own.

I think you have enabled the 'double tap to wake' option. Sometimes when you hold the phone and touch the screen, it recognizes it as if you double tap it, and then face unlock kicks in. I personally have enabled an extra required swipe up after face unlock to unlock my phone as a solution.
Yes, I have been using double tap to wake, and everything was fine, as I have the phone since the launch. I have started noticing the issues recently. Also, if just touching the screen activates the "double tap" then obviously something is not right, because it happens quite often. I have disabled pocket mode for now to see if anything changes.
