Post OxygenOS 4.7.6 update, when "face unlock assistive lighting" turned on, in complete dark, OnePlus 5T can be unlocked with both eyes totally closed. How I noticed this? even when both eyes are closed ?...... In complete dark the screen becomes very bright to scan the face(one can feel it with both eyes closed in complete dark as the screen becomes pale/unbright suddenly signalling the screen being unlocked). And then moved away the phone to a distance where the phone no way can see the face. Saw the phone already being unlocked. Did it many times to see, every-time it showed the same result. Then I asked my friend to hold the phone in front of my face(with my eyes closed, in total dark) to verify. He clarified it unlocked even when my eyes were fully closed. Did repetitively, same result. I did check this with another OnePlus 5T that I have in my house, got same result. Also, I factory reset the phone, re-registered the face data and checked it a few more times only to get the same result everytime. This is to be noted that in well-lit environment face unlock doesn't work if both eyes are closed with the same settings. Lastly, I experimented it with 2 different friends of mine ,face unlocked with both eyes closed with one, didn't work with the other one. I request OnePlus 5T owners to check this on their own..... What it proves is that, anyone can unlock the phone when the actual owner is sleeping by holding the phone in front the face in dark. This is unsafe. Now is this an issue? I leave it to the users.
I posted this experience in other forums as well, got mixed reactions from users as some said it unlocked with both eyes completely closed like mine and some said it did not. For me, it works every-time in dark ,both eyes closed
Conditions:
(a) The environment has to be very dark or completely dark.
(b)Face unlock, Auto unlock when the screen is on & Face unlock assistive lighting has to be on in Face unlock settings.
(c) Phone should be 10 inches or more away from the face.

Yeah, but does not unlock in well lit environment if both eyes are closed.
I don't see this as a security flaw, since it's already established that face unlock is not a fully secure method of unlocking and not used for mobile payments or banking. It's just a shortcut. Just like a fingerprint can be used from a sleeping or dead person. Not safe. Pin/password is still the safest method to unlock a phone.
It doesn't have a Samsung retina scanner...and it doesn't scan your eyeballs. Just the points of your face...
Now, if the fingerprint scanner works in the dark with my eyes closed, then I'll be worried
Seriously, I can't get face unlock to work with my eyes closed on Oreo Beta, but I'm not that worried about it. Like has been said above, face unlock isn't the way to go if you're worried about security.
I'm getting quite the opposite effect. I tried to do what the op is saying. So it's 2am, I'm in my bedroom pitch black. Try to unlock my phone with eyes closed but it doesn't work.
As soon as I open my eyes, it unlocks. Damn this face scanner is so fast and accurate!

One improvement I can say is that when assistive lighting is on, to still show notifications.
The notifications are white even with substratum themes so it shouldn't affect the assistive lighting much.
So in the night, when you wanna check your notifs but the phone puts the assistive light on instead and you have to press close.
Just skipping that close step really.
I think the OnePlus's implementation of face unlock is flawed to begin with, and the fact that you are able to unlock with your eyes closed in the dark is the least of your problems. I've been able to unlock the phone using a picture taken with a camera phone and displayed on that phone's screen. Heed OnePlus's warning that face unlock should be used as a convenience and not as a security measure.

Definitely enjoying the Nexus 6P after getting it yesterday. After bringing it to work that, I have to say that it's a little frustrating having to pick it up to unlock it with the fingerprint reader on the back. Coming from a Galaxy S6 this wasn't an issue since it was on the front. Besides that I'm definitely enjoying this phone more.
I was thinking about getting a dock for it, but realizing it would be the and issue. This is where double tap to wake would really come in handy if a dev ends up figuring out a way to get that to work (if it's even possible).
I was going to try to look into making my fitbit a trusted device if possible which could help the issue. Anyone else struggling a bit with the same thing? I really like having the fingerprint reader on the back otherwise. Or anything else people are using for this? I definitely don't want to set a trusted location at work...
Thanks in advance!

are you to lazy to press the power button on the side and punching in a code?
While the phone is face up on the desk you can still unlock the phone by swiping up from the bottom of the screen and using your normal unlock method. The other option is to lay it face down and touch the sensor before picking it up.
I was thinking about not using Smart Lock because of the finger print sensor. I found it convenient to have it unlock paired to my smart watch because of this reason. I don't have to pick it up to unlock.
I Smart Lock with my Pebble Time, and a 5 second lock delay when not paired. I wear my watch when I'm out of the house but it usually stays within range and unlocked when I'm at home as well. I do find myself still using the fingerprint scanner to wake the device as I take it out of my pocket even when a PIN isn't required.

Unfortunately I've never found smartlock with a fitbit reliable. It only senses the fitbit when the fitbit syncs....it's not always connected. But for real....press the side button and punch in your pin. 1st world problems.
I turned off the finger print scanner for this reason alone. Now I'm just waiting for NRT (I'm too lazy to manual root these days) to be updated so i can root it and fix the rotation on the lockscreen and hopefully add double tap to wake as well. I normally have my phone on a cell phone stand when I'm at my desk, so its always in landscape. Not having the lockscreen able to rotate is dumb, especially in the car. I'm also thinking of just putting one of those NFC stickers on that cell phone stand at work. Just need to find the ones i have.
Dt2w is available with flar2's kernel now
Double tap to wake is available with stock kernel, as well. Just need to enable it using the code in flar2's kernel thread. Of course, this requires root.
On topic, I find myself lifting the phone up to use my fingerprint to unlock the device. Sure, I could double tap it and input my pattern, but it seems easier to just pick it up.
Wasn't trying to come across as lazy (although I'm sure I did!) Just adjusting to the fingerprint reader on the back and was trying to get different thoughts. I'm possibly going to give double tap to wake a try, thanks for mentioning that.

Dont worry about it, I don't like it either. A sensor in front is just as easy to use and unlike the rear sensor can be used without picking up the phone. Nor do I want to enter in my very long and complex password every time I want to check my notifications, use the calculator, etc. as the phone sits next to me on the desk. Calling this lazy is baffling to me, I work hard to lay out my phone out and configure it so it can perform with absolute maximum efficiency allowing me to get get to and use any application or the phone itself with the minimum time invested. Of course everyone knows they can enter their password as an alternative, suggesting it is pointless and why anyone would want to I cant guess.
For me in the most part it's a non issue because the majority of times when I have the phone sitting next to me in that scenario it's at work or at home and the phone is already unlocked. Double tap and I'm rolling. Course I knew all this going in but I had hoped I'd make friends with the rear location and that hasn't happened and probably wont. I like this phone, pretty darn solid device but its not perfect.
If the sensor was on the front, people would complain it wasn't on the back. Can't please everyone with that.
In my opinion, it's in the perfect spot. Coming form a Nexus 6 and before that a Moto X 2013, I loved the dimple and always put my finger there naturally. The Nexus Imprint is the same way. Today I forgot my Pebble Time on the charger so Smart Lock isn't active. Using the sensor is working great instead of entering my PIN. I think the placement on the back makes the most sense because there is already a way to unlock from the front (touch screen). Putting both on the front would likely mean a bigger device/smaller screen or very odd placement (off the the side of the speaker or something). The only happy medium would be putting it on the side with the power button, but that could still mean you'd wear out the physical power button using it all the time. The Nexus Imprint has no moving parts and saves your power button for the good stuff like getting into the bootloader.
I use smart lock with locations for my home and office so i don't need to unlock the phone when it's on a desk at work or at home. I also set my phone lock to 20 min after sleep and to not lock instantly when power button is pressed. I don't see the need for your phone to be constantly locked. If I leave it somewhere it will lock in 20 mins but if I'm actively using it then I don't want to to keep locking.

I do the same thing. I made home and work trusted places and use the phone at my desk without having to worry about unlocking it.
I personally use Smart Lock with my Moto 360. Works well for me.

I could never get smart location to work for me. it's really odd that yours stays unlocked at home.

I don't use it, but I've seen people say that it works better if you setup four locations directly around your home instead of just one centered on it. This way they overlap and if you're in any of them, you'll be unlocked. The very center being the most saturated area with all four circles overlapping.
i came from Lg G3 so it may have been removed from previous models but if not, does anyone know where the smart screen setting would be (keep screen on while looking at it) and if its no longer available on the G6 anyone knows of an app that would do the job?

No longer an option and not sure why it was removed. I don't remember it being there on the G5 either. Could me an Android limitation now. You can enable "on body" detection which essentially does the same thing.
As far as for an app, I don't think there's one out there.

on body detection is not the same as stay on while looking at the screen. the on body detection is only good to keep phone unlocked which is useless for me since i dont even set up a lock on my phone anyways. i like the double tap to go to the main screen rather than unlocking it, although i have tried the finger print scanner which 90% of the times takes me direct to the main screen and 10% fails and takes me to the lock screen.

Ah, right. Guess most apps stay alive now that I need to. Although reading would be nice, except probably wouldn't recognize my eye at night in the dark.

Hello, my iris scanner totally doesn't detect me in the dark. I am always struggling to set it up and it takes several attempts to do it. Also it works not really fast. I thought this is how it should be but then I saw a video where guy unlocks his s8 in total darkness. I can't do that. Tried re registering iris at dark, but it doesn't detect my eyes at all. Stays at 0%. Ofc I cleaned the sensor. The image in the iris camera is still blurry I don't know if it's ok.
Anyways, anyone had such problem? Or it's a hardware issue? Thanks in advance.
UPDATE LOL just after making this thread I tried registering iris in the dark again and it worked. Xda helps

Bring the phone close to your eyes it works well in pitch dark.

Yeah I already updated the post, suddenly it started working, thanks.
Still it takes around 5 seconds to unlock in low light condition and few attempts to unlock in the dark. On YouTube people unlock it instantly in low light condition. Cabln somebody recommend a fix? Maybe factory reset? I have a rooted phone and often flash custom Roms with full wipes but it doesn't seem to help.
IRIS Camera registration and usage
To register your irises:
Find somewhere with good light,
Look straight ahead,
Lift your phone so that you are looking at the top bar and your phone is perpendicular (flat) to your face,
Blink a few times,
Activate the registration procedure and blink just as it starts and before it succeeds - that might cause a retry.
Now your eyes are registered without dust, dirt or excess fluid on the surface. Try "face recognition" first, and a few times, to get the hang of holding your phone for a 'registration selfie' (not quite the same as your usual selfie).
Once you have registered in good lighting it should work in the dark. If the phone is giving you instructions (hold phone higher, closer, further away) be certain to follow those instructions. While it is detecting your irises be certain to blink once - with the Galaxy S9+ it should recognize you almost instantly (less than a 1/10 of a second).
Cleaning the lens is a good idea, so is holding the phone correctly during registration and detection - but don't forget to 'clean your irises' - remember to blink!
Hi, some days ago I decided to fully reset my OP5, because of some software problem caused by me. Then I chosed the last stable software, without Root acces. Then I configured my phone and I noticed some little delay when trying to unlock the phone in both methods. I did not know wich was the problem, so I decided to perform another hard reset, chosing the last beta firmware. Nothing to do, I have the same problem. Specifically if I use ambient display and I try to unlock the phone via fingerprint when it shows the time (maybe bacause I take my phone by a table), all work good, but if I try to unlock when screen is totally off I have to wait for 1 second and more. This problems disappear If I do not use ambient display. Instead, If I use Face unlock, I always see the vertical fade animation, even if I am perfectly in front of my phone, but until some days ago the unlock was very quick, like a "not protected phone". I hope you can help me guys, it's difficult to have a very quick phone and not being able to use it. Thanks.
P.S. I'm sorry, but my English isn't perfect.
It's a small thing, but it bugs me in my daily use of my phone. I recently got my A40 and upgraded Android from 9 to 11, and now I can't lock the phone by touching the fingerprint sensor anymore . But unlocking works fine though. I have been googling around but noone seems to have this problem.
Do anyone in here have aclue to what might be the problem here ?
Since when could you even lock the phone using the fingerprint sensor?
Nonetheless, this is the XDA community of developers, and im sure a random person just needed this functionality on their phone, so they made and app for it..
Anyways, here's a link to a tutorial. It covers exactly what you want, and apparently the app is developed by a couple of XDA developers, so it should be safe too

From the get-go, when I bought my phone. Thought it was normal. My old Moto G5 did same thing. Really handy when you just need to view whatever is on the screen for a short moment.
Locking the screen means turning it off.. (and locking your device so that you have to scan your finger or use a pattern to unlock it again)

Otherwise yes, the phone's screen will turn on on the lock screen if you touch the sensor and the fingerprint isnt recognised. That's not the same as locking your phone. Locking your phone is the equivalent of pressing the power button once, which puts your phone into sleep and forces you to unlock it again (via fingerprint/pattern etc)
Can you clarify what you're asking for here?
Do you want the screen t oturn on when you tap the sensor or do you want the screen to turn off when you tap the sensor?
And do you want it to unlock when you tap the sensor, or do you want it to turn the screen on onto the lockscreen so that you can see the time/notifications etc?
(The links I posted are for LOCKING your phone using the sensor (turning the screen off and locking it, causing you to have to unlock it again when you turn it back on), because that's what you asked for..

I found the app. But somehow it didnt work on my phone. Only worked while app was open. And it made me unable to unlock with fingerprint
Thx anyway for the fast reply. Looks like I have to live with it for a while. Im pretty happy with my phone otherwise!
