Fingerprint sensor - Samsung Galaxy S8+ Questions & Answers

Hi
I’m considering buying the s8 plus,would really appreciate if someone could answer this question.
Can placing or tapping the fingerprint sensor wake the phone,I mean,without pressing the power button then fingerprint to unlock screen?
Cheers.

I use always on display and the fingerprint sensor unlocks my phone without me having to double tap the home button.

Yes...

Yeah, I use it on mine.

Yes it does. As long as our fingerprint is recognized it will unlock it. Very fast as well.

Fingerprint scanner problem

I can open my phone by the fingerprint scanner and open encrypted apps but I can't lock the phone using the fingerprint scanner. Purchased the phone yesterday.
Lock the phone? As in locking the device? I'm sorry AFAIK, the oppo r7 plus does not have that feature. If the unlocking and app encryption are working like it is suppose to, then there is no problem with your phone.
lock it by pressing the power button as normal or you can double tap the home button to lock the device - need to be set in Gestures settings first.

Screen off and lock PIN Bug

Hi all,
I've always used the application "Screen off and lock" to quickly turn off my Z5 without pressing the side lock button. My button works fine I just find this to be quicker.
However now with marshmallow after I lock the phone using the application, when I wake it up again it won't unlock with my fingerprint, it forces me to unlock the phone with with my pin. It vibrates as if my fingerprint is accepted, but it won't unlock beyond the pin screen.
If I lock the phone normally by pressing the side lock button it will unlock with my fingerprint like normal.
I've tried multiple applications that do the same thing and have made sure to give them the lock permission but I keep running into the same pin screen issue.
Has anyone else encountered this problem?
Don't use the fingerprint icon, it locks your phone so it requires pin to unlock, you can slide to unlock as previously, or just use the power button to lock screen, then you can unlock with the fingerprint sensor with exception of first boot where you are forced to use pin first time unlock.
Don't quite understand maybe what you are trying to explain, to wake phone you have to push the button, IMO it is faster to just hold your thumb there for a second longer for unlock. Also not sure this is a bug

So when I use this application
https://play.google.com/store/apps/details?id=com.katecca.screenofflock&hl=en
to lock my Z5, when I wake it back up it won't unlock with my fingerprint it keeps asking for my pin.
But when I lock it with the lock button then wake it up it accepts my fingerprint instantly.

Sorry now I am with you, same issue here. Although it would seem the app is not compatible with the 6.0 fingerprint framework, because it doesn't work on pretty much any phone from what I can tell
same here.. i guess it's a bug and we need to wait for the next update that includes Stamina Mode perhaps?
Also for me it's a bug. With lock screen program the fingerprint sensor does not unlock the phone. The fingerprint sensor works only with using a button lock.
I face the same issue with Tasker and Nova Launcher. Worked fine on 5.1.1.
me too
+1 for me too

There's a ticket in Google Android about this, it's the same in Nexus phones. You have workarounds if rooted.
all screen lock apps are not compatible with Marshmallow yet - it requires to use the back up pin/pattern after using the fingerprint . Though, if you uninstall the app - the fingerprint will work without using the pin anymore T_T
I use gravitybox shortcut to sleep the phone. It work.

Fingerprint unlock does not work

Hello,
I always have to press the powerbutton first, before I can unlock the phone via the fingerprint sensor.
Is that normal?
yes, thats how it works on sony phones ... and i must say i like it, because of accidental touches i used to have on nexus 6p
If you are using tap to wake you don't have to press power button just put your finger on fingerprint scanner
doesnt work. Still have to press the power button first.
By the way...tap to wake up does not work on the XZ like it should: https://talk.sonymobile.com/t5/Xperia-XZ/Double-tap-to-wake-not-working-properly/td-p/1168519
People are so lazy that they can't even press a button nowadays.

yup, but he is right tap to wake is little off on xz( this feature worked fine on g3) and after awakening screen it should be possible to unlock it by touching fingerprint scanner
Once the screen is on, just touching the sensor unlocks for me.

Yes, this works. I am coming from a HTC 10 and here things are different.
If it helps, check out Gravity Screen, which can mimic Ambient Display-like functionality by waking up the notification screen via either proximity sensor or motion or a whole bunch of other stuff. Personally, I only use proximity sensor so the phone wakes up as I take it out of the pocket, then I just have to tap the sensor to unlock.

is it me or is it a pain in the @@@ to turn thid phone on

I don't know, maybe it's me, but i always feel like there is a moment of frustration when i have to turn the device on.
On my mate 9 I literally picked up the device and easily touched the fingerprint sensor which is placed away from anywhere else and obvious to find. Bang, it's on. On this device OMG it's so freaking frustrating, whether I have e a case or not. I'm always fiddling around trying to find it.
If i want to use face or Iris, it's two steps. First I have elto find the power button and then switch it on, then stuff this thing in front of my face. Also annoying, never that quick and obtrusive if you are with other people, . If I'm in the car at a red light, and there's any movement it often takes a few seconds. Really annoying.
If I'm in a meeting and I want to quickly check something i have to find the power button and them use a pin or pattern. Again, front fingerprint sensor is better for that.
The always on would be better served if it could double tap to wake, then when on a table at least i could check for messages without ping up the phone.
All in all I'm finding it frustrating. Or is it just me.
I agree completely. I'm forever forgetting that picking up the device doesn't just turn it on and that I have to press the button. Does anyone know of an easier way to wake the device so all I have to do is tap the fingerprint sensor?

One thing I did find is that if you set up the fingerprint scanner, that touching the fingerprint scanner immediately unlocks and turns on the device.
Iris scanner not a problem for me at all, I set the virtual home button force press to activate it straight away, power button or home button doubletap lets me see my notifications without activating the iris scanner. I always hold my phone in the angle that the iris scanner works in, so it usually takes less than one second to go from screen off to home screen, with the iris scanner and force-touch combo. But everyone has different ways of using their devices, so a non-issue for me might be a big issue for someone else
I turned off the always on display. Less frustrating!
Is there a way to make power go on when you pick k up the device?
When AOD is on you can just double tap the home button to wake the device. Just an fyi

Yep it is just you, you a a special kind.
Iris scanner works for me driving in the dark when phone is mounted on my magnetic windshield mount. Took a while to get the placement right tho but rest assured-iris is wonderful it just takes trial and error

For the first few hours I was regretting upgrading. Now I could never go back. It just takes getting used to.

The issue for me with the read scanner is the stupid placement. i constantly have to tap it twice because to hit it the first time i have to kinda slide my finger across the back to find it, then lift off and press down again to activate it. It would be a lot better if i didnt need to lift and press again, then if it didnt read it when i slide my finger over it into position (because it has tried to read it before my finger was properly over the scanner), then it would read it 5ms later when it was actually in the correct place. instead it fails to read it and i need to lift my finger off it before it will try again.
The second issue for me is even bigger, if phone is sitting on the desk, there is no quick easy way to unlock it. i cant get to the fingerprint scanner, and to use the iris scanner i would have to stand up and move my head over the top of the desk. so the only option without picking the thing up is to activate it with a hard home button press and then type in the pin. if the fingerprint scanner was on the front, then it would be perfect, just put my finger on it and its done.
The only thing keeping me sane at the moment is that I just came from an S5 where the only way to unlock it was home key, THEN swipe away the stupid false second lock screen, THEN entering pin/pattern. Even hitting the fingerprint scanner wrongly a couple of times is still so much faster than unlocking my s5 was but this could have been so much better if it was on the front (or one the back in a sensible place like slightly below the camera and in the middle.
Sounds like you guys need to change some settings.
MY phone is fast and easy. Pick it up and put my finger on the fingerprint sensor and im at the home screen.
Press power button and the iris picks up right away and im at the home screen.
To start off make sure you setup your iris scanner good. Make sure your in well lite lighting and the front camera is clean and clear.
Second in your settings under Lock Screen > Iris Sensor > Iris Unlock ON , Iris unlock when screen turns on ON,
Then for finger print the same thing. Fingerprint Scanner > Fingerprint unlock ON
I find it easier just use the fingerprint sensor or the virtual home button. When the phone's off, you can just put your whole fingertip on the sensor and it automatically unlocks (if it verifies you print properly). Also the virtual home button works when the screen's off. you can hold the home button when the screen's off, then choose your unlock method. Other than that it's a pain to press the power button, then use the fingerprint sensor or pattern unlock.
I bounce between fingerprint and facial recognition. It's taking some getting used to but it isn't that bad.
You can also set it to just use force touch to unlock the phone

Quick tip, In display settings -> navigation bar -> enable home press to unlock.
Found that by doing this its so much quicker accessing the iris scanner or going straight to pin/pattern screen.
In case you didn't know, you can press the home button when the screen is off [yes, you can totally press it when the screen if off!]
Phone is super fast for me. Scanner could be in a better postion but it works fine. Also try out smart lock. It let you trust certain places and not have to use anything to unlock.
I haven't had issues turning on the phone, but if you have the AOD on, it is a lil annoying since you have to press the home button on the screen with some pressure before you go to the lock screen, especially if you use anything else, besides the fingerprint sensor as it will unlock while being on the AOD, to unlock you phone.
I will say that setting up the fingerprint scanner is slightly annoying since if your finger isn't on there just right, it'll give you an error. After it's setup, I've found that it works pretty well. And, if you use a case on your phone, thicker cases might be a slight problem. I noticed that while locating the sensor is easier with a case, thicker case, like the Spigen Slim Armor, will be harder because of the added lip.

Unlock through fingerprint with no lockscreen?

I'm interested in buying the OP7 but want a fast and uncomplicated fingerprint unlock experience. In all the videos I saw people first double tap the screen and then unlock through fingerprint, so my question is if it's possible to skip the step of double tapping somehow to directly unlock the phone.
Thank you!
Well there's an option to turn on ambient display on pickup, so you can activate the fingerprint right after picking it up.
On the other hand you can try using the face unlock after powering the screen on through the power button or double tap. Face unlock is super fast too!
Cheers.

Fp sensor is not as fast as a sensor that is not behind the screen like the OP6 and since you can't feel the location of the sensor you can't just guess where it is and always need to look at the screen but it works well enough. Especially in combination with face unlock. One or the other will unlock quickly enough.
