[Q] Face unlock doesn't work in android 5.0 - Nexus 5 Q&A, Help & Troubleshooting

Hello guys,
As I said in the title, face unlock doesn't work for me in android 5.0 LRX21O. It didn't work in preview versions also.
I have read several reviews on this feature, watched several videos, but i have never managed not once to unlock the device this way. I think i have registered almost 20 conditions for face matching, in different light condition, but the result is the same, it doesn't unlock the phone this way.
How is your experience with this feature?

Workinbg fine her ei don't see any proble mat all

probably your face is not compatible with this feature.
I had no problems here

Lol.
Probably, that's the only face I have unfortunately.. But seriously, it worked in KitKat.
Well, gonna ask a friend to set up this with his face and see how this will turn out.

it doesn't work for me either! I've tried to improve the matching also. It worked better when it first came out on the Galaxy Nexus.
I flashed the image via Mac and each partiton one at a time. I'm wondering if you did a full wipe including the user data? I didn't so I'm going to try that next maybe, or maybe wipe a particular folder in the system data to try again. I haven't bothered to root the phone yet I was going to do that at some point in the next few days.

It works for me if the room has good light conditions

you might be expecting it to open to your homescreen like it used to. it doesn't do that. it simply (and very subtley) just unlocks the lock icon at the bottom which then allows you to swipe up without having to enter your pin or pattern.

nop, i know how it works.
i have discovered what the problem was. i was locking the screen with an app and not by power button, so for a reason i do not know, the face unlock doesn't work if you lock the device this way.

[Q] io6 like unlock to camera with pin lock screen?

hi all. quick question for you guys: is there anyway to get unlock to camera with the pin lock engaged on the Nexus S like the iOS implementation?
I have to say that iOS implementation of unlock to camera with pin lock is the best in business for the time being.
for those who haven't seen it: on the iOS implementation, when facing a pin locked screen, anyone can still unlock directly to camera and take photos. AND they can even browse the gallery but the gallery only allows access to the photos that are just taken (phone still locked).
it's even session based. the next time the phone locks again, the user can still unlock directly to camera and gallery like the last time, but the photos taken from the last session while the phone was still locked are now hidden and not shown. so each time the gallery only shows the photos the are just taken.
all photos, of course, are added to the gallery.
it's brilliant! is there any way to get something close to this on a custom ROM on a Nexus S?
Thanks, all! :good:
Yes, it's called android 4.2. Watch it in youtube its quite interesting

This did not show it working with Pin Lock Screen though (as requested by op)...
I did have the video on mute due to being at work and might have missed him saying that it also works with pin lock screen...
It does work with pin lock. Saw a review from a guy at Google. Looks awesome. You can add the camera to one of the widgets. You can take pictures and view the pictures you just took. Upon switching to sleep mode and on again you can't see the pictures you just took.

Pocket unlock

Had anyone experienced their device being unlocked while in their pocket. Mine had several times, even some quick toggles have been changed from where I had them set. Apps opened, not just opened but digging into multiple button presses. Even today mi wife says I called her twice while phone in pocket. I use fingerprint security with pin backup and somehow phone is bypassing both of theses in my pocket. I've tried numerous times to replicate out of my pocket with no avail. I'm on stock TMobile no mods or rooted.

It happened many times for me.. you might be having Smart Lock enabled... even then, proximity sensor on OnePlus 7 Pro isn't good.. but disabling smart Lock should fix your issue
Yeah I checked and smart Lock has always been off
I encountered the same issue today

Weird. Do you have fingerprint lock enabled?
Yes I do. From what I can find on the web previous OnePlus devices had a Pocket Mode which is not present on the 7 pro. But viewing T-Mobiles website under settings list it shows it is in the utilities section under settings. But not on my phone. I even searched for it with the search option at the top of settings menu.
I've also noticed that in settings under utilities there is a section called app locker, when I click on it, it asks for pin and then just resorts back to the utilities menu giving me no option to add apps to list. It does nothing.

What Pocket Mode did (I had it on my 3T) was ignore screen touches, if the proximity sensor sensed an object nearby (assuming it was your pocket).
Even without Pocket Mode, a press on the screen, or movement of the gyro should only turn on the "ambient display" screen. You can't do anything from that screen except scan your fingerprint (which you confirmed you have fingerprint security enabled). So I'm puzzled how the butt dials or other things occurred in your pocket.
I suppose it's possible the power button is being accidentally pressed in your pants. Which brings up the lock screen - slightly different from the ambient display screen, as it gives access to the quick toggles, camera and voice assist. But it would seem like a strange combination of accidental power button pressing and screen touches happening in your pants, to make the things you mentioned happen. TWSS

Can anyone who has converted to international firmware confirm that pocket mode is or is not present in the settings under utilities?

If you just look in the settings there is custom mode under natural that allows adjustment. Stock room stock kernel.

What is the most missed feature, compared to past Pixels?

For me, it'll have to be the notification LED I really miss that. Had different colours for different apps and even people, so I knew who or what it was without even picking up my phone to check.
I also miss the fingerprint sensor on all the banking apps etc but that'll be resolved in due course once the developers switch to the biometric API for Face Unlock.
What is it for you?

+ 1 on everything you have statted.
I have not yet purchased the Pixel 4 xl
And dont know if I will
Definitely rather have a LED light than AOD for sure.
Only the original quality photos and videos backup but not really. I'm actually using my 100GB Google One storage which I hardly touched. At my current rate of 1GB per 12 days, I'll be needing more space in just under 3 years. [emoji23]

Hands down the finger print sensor. ? Unlimited Full Photo Backup as well. Wide angle selfie camera. I didn't think it was a huge deal on the 3 but I ended up using it quite a bit.
For sure LED notification and fingerprint sensor. I like the face unlock but also want to have the choice to not use it and use a fingerprint instead. There's many times I will pull my phone out just to see the time then POOF...unlocked. Ugh! lol
(yes, I know PIN/Pattern can be used in lieu of face unlock)

There is also a setting to face unlock then go to the "lock screen" rather than all the way in. That's what I do. So tap the screen to see notifications or face unlock then swipe up.
Settings -> Display -> Lock Screen Display -> Skip Lock Screen toggle : On skips directly to last screen used (like your home screen). Turn it off and Face Unlock goes to your lock screen and you just swipe up to then go to the home screen.
nothing. I thought I'd miss the fingerprint sensor, but I don't Face unlock is so fast it would be unlocked before I could place my finger. I would like an ultra wide lens and top bezel to shrink but that was not on the older models either...just hoping those 2 are done on P5
I have a TB on Google one, so not a huge issue for me with photos. I save original quality. I had my subscription last year as well.
Autofocus for the front-cam, no doubt...
Biometric API is really bugging me and I bet we could wait a very, very long time before Devs start actually updating for it.
Nothing really. I thought I'd miss the LED, but I haven't really noticed it being gone much. The fingerprint sensor some, but mainly because a lot of my apps use it. Definitely miss the convenience of it. I'll be very happy once they start using the new API. I sort of miss the metal back of the 2xl. But, wireless charging is awesome, so it's kind of a toss up.
I DEFINITELY don't miss the notch on the 3. I didn't think it bothered me, until I got this phone. Now I can't understand how I went a full year with it...
At least for as long as only a few apps support biometric unlocking, it definitely is the fingerprint scanner. But I'm sure it's only a medium-term loss, and we'll see more apps being able to use biometric unlock very soon.

Android 11 Dev Preview new stuff

I just flashed the new Android 11 beta on my Pixel 4 to just check out what's new and thought we could have a little discussion about some of the bigger changes and opinions. The changes I immediately am excited about are:
1) Finally added a pause/play gesture to project Soli!! (Works fantastic)
2) In the display settings, there is now a toggle to increase display touch sensitivity for screen protectors
3) Added a new qs icon for the built in screen recording
While testing the new Soli pause/play, I also immediately noticed how much more improved all of the hand gestures are. Not just the new pause, but also the skipping forward and backwards are so much more accurate and successful for me. It's an extremely welcome change and while Soli always worked decent for me, on the 11 beta I'm getting about 95%-99% success on all hand gestures compared to my about 80% on Android 10.
The screen sensitivity is another welcome addition for me personally. I have a glass screen protector and with the new option enabled, I can absolutely feel a difference in display response. I will admit that before updating, I hadn't had any screen responsiveness complaints but now that there's an option to improve it, I am very pleased with the results. If anything, it may be a tiny bit too responsive. While typing this post out, Gboard seems to occasionally hit a letter before I actually make contact with the screen. Other than that, it's fantastic. My back gestures seem to be the most beneficial from this.
The screen recording qs icon is a cool new addition, although I had native screen recording enabled on Android 10, there was no super quick way to start a recording session.
Lastly, I noticed a few new things in developer options but as I'm no Dev, I really don't know what they do. Oh, they did add a screen frame-rate overlay so you can see the current refresh rate of your screen.
I will be running this for a few days to see if and how battery life is affected and I'll post my findings here. Feel free to comment additional findings or opinions on the new Android 11 beta!
Here are some screenshots of my findings so far.

Strange, I haven't heard of this being an issue for anyone else yet. I even dirty flashed the 11 beta, didn't erase my userdata so I was expecting issues and it's been flawless. Try re-flashing the Android 11 factory image, that we almost certainly fix your issue.

Face unlock working fine here too, only issue I had was I didn't extract the zip into its entirety of the platform tools folder. That took me 2 hours to figure out how to flash without error.

Yeah, Google pay does not work on it. I received a pop up about it earlier this morning.
For those having face unlock setup issues: Factory reset your phone either in recovery or the settings menu. This happens when you don't clear face unlock before flashing a factory image with the -w option.
(Also, finally hitting my 1000th post with this 10 years later... Can't believe it's been that long)

Hmm. Was afraid to read that. So if we are able to use Google pay we have to wait until Google ads the preview to safely net to pass i think... So i wait... G-Pay is evident to me.

Nope, unfortunately the Pixel line will most likely never have hardware HDMI out capability due to the Chromecast's existence. I have a Chromecast and still would love to have HDMI over usb-c, it's just not going to happen.

Improve face unlock

Anyone have problem with face unlock about bad angles or not working under bright sunlight! Just set up face unlock under direct sunlight! make sure sunlight sight direct into your face when setting up. Hope that's helpful, it works for me at least
Ps: if you are wearing glasses, put them on when setup.
My biggest issue with face unlock is random challenge to unlock with PIN for "added security".
I say random because I've not rebooted the phone. The message is different when rebooting. I've sent numerous feedback with logs to Google but Google doesn't respond to feedback. I have no idea why this happens. It's annoying. This can happen as often as once a day at random unless I'm missing the reason for it. Maybe it works for days without error. Maybe this is required at intervals I've not recognized?
Patterns I've noticed otherwise include a pause to unlock when I grab my phone and it's upside down. It usually gives me time to recognize this and get screen upright. My phone is usually on a stand upright in portrait mode so it's rare that I pick it up with screen not orientated correctly.
I've not tried setting up face unlock in bright setting though.

your problems is totally different with what I mean to. However, It think your problem could be from software or setting. you would reset your phone. And if that keep going, using google warranty is best choice.

Thanks. I should talk to Google Pixel support again. I've been reluctant since they couldn't resolve an issue with Google Home app. They referred me to Google Home app support but they kept getting stuck on the fact they support hardware, not the app. I could link Google and Philips Hue but couldn't add Philips Hue to Google Home app. Failing every time.
Long story but the mobile apps kept telling me that that there was an issue getting provider information for Philips Hue. Yet it went through all the steps and failed at the end, never adding Philips Hue. This once worked until it stopped; nothing I was doing was working, even asking Google and Philips for support was pointless with them refusing to talk to each other or continue support with me until resolution. One day my phone had a notification to control my lights and the linking and final step worked that time. I followed the notification and seemingly skipped several steps I've went through to failure but this time everything went as expected and I can control my lights again. Finally! What was the issue? Google won't say but I suspect they discovered it long after I gave up. Months!
I've seen face unlock improvements in the notes of the monthly updates so I've thought Google is aware but like before, not on my timetable. Low priority. With my past slate now clean, start a new one.

The issue you explained about the seemingly random pin requirement is actually not an issue at all. It's coded into the software as an extra security measure. If you lock your phone and do not unlock it for XXX amount of time (eg. 1 hour) then the phone requires your pin or pattern to verify its still you and your phone hasn't been physically compromised. The other trigger for this happening is at or around 6 hours since the last time your pin was physically entered, it will require you to enter it for the same reasons I listed before. Using face unlock doesn't reset the 6 hours, only physically entering your pin code will.
Hope this helps you understand a little better what's going on with your phone. We all have the same thing happen to us, just most don't notice it when it happens.

Your hour or six a guess, estimation or actual?
What you described seems true but my use would likely indicate more quiring for PIN than I experience. Just asking.
But if this is intent, I don't agree PIN is added security. Sure face ID can be duped in many ways but at the very least what I'd prefer is safe zone like home where face unlock never dupes to PIN or added security. As I recall, total unlock is only option for designated safe zone like home, unless considering Bluetooth device which I don't prefer unless it can distinguish my Fitbit Versa 2 watch is very near and worn?
Surely there's less invasive methods users can deploy to not be so inconvenienced at home. I've even seen this at work with my wife's iPhone X. More choices seems a logical approach to consider. Why hasn't it?
Phone on charger just now, after just talking to Google Assistant, give a smart home command it interprets correctly, the smart assistant says sure, after you unlock your phone. I dismiss the Google Assistant and promptly unlock my phone without the stupid PIN. Not being very user friendly. I'm under the impression many developers don't just use the device and rethink their intents to be most user friendly.

I feel like I don't see this message more than twice a week... which certainly goes against the every 6 hours idea. My impression was that sometimes movement or Soli will wake it up and it sees something it thinks is a face but it can't unlock with it. If it sees this enough, it may prompt for a PIN unlock with the different message. But sometimes, I think I see this message taking it out of my pocket... where it can't possibly see a face. But maybe it saw part of my face as I was putting it in. It would be interesting to know what the actual rules are regarding this.
I know that when I have the screen upside down, the screen wakes but gives me time to get it upright. Seconds. I don't recall seeing this fail me, thankfully.
I don't have much or any of the Soli features enabled but have screen tap to wake and skip unlock screen enabled.
I've wondered if having the generic stand was causing random face unlock errors but reach for phone is disabled. And I've tried placing my screen down flat instead of the stand and still got prompts to unlock with PIN.
Sometimes I grab my phone and tap to wake doesn't work. But it doesn't mean I get a prompt for PIN every time either. Yesterday, I tapped on the screen repeatedly and it woke and unlocked when it recognized my face. Maybe it's a latent response but I'm usually using the power button to wake by then.

So I did a chat with Pixel support today.
For the issues with frequent queries for PIN and Voice Assistant asking me to unlock my phone first, the agent had me delete storage and cache for Google and Phone app, delete face unlock and add it back. Reboot phone and get back with them if this doesn't help.
The agent indicated there's not a timer that cannot be reset with unlock that would naturally challenge for PIN after counting down. His advice is to do the above for that issue. The face unlock is suspect. I hadn't done this until today. For kicks, I tried it outside in daylight though the agent didn't recommend this idea. Fwiw, I can unlock my phone in the dark but maybe daylight helps better see contours of the face.
I have a case number to chat again if this continues. Agent says it shouldn't reoccur.

I only have a basic understanding of how face unlock works... but from what I understand it uses an IR dot projector and two IR cameras to stereoscopically sense the depth of your face. This is why it works in the dark to begin with and based on this, I would think direct sunlight would be a detriment rather than a boon in this sensing method. But it may not have any effect at all as I don't know exactly how the sun and the dot projector overlap in wavelength and strength.
Having a "bad" face calibration might explain it as the phone is more often unconfident about it being your face. So it triggers more failures which prompts the increased security message.

Agreed. It's unknown if added light is a help, hindrance or placebo. But the agent seemed confident just replacing the face unlock would solve my issues.
Not all of my issues sounded familiar was the reason for suggested extra storage wipes and reboot.

I spoke from my experience. Before that if i will to unlock i have to keep it direct to my face as the right distance or angles and it hardly work with changing light conditions like under direct sunlight. But after set up with aid from sunlight i could say it work quick and more reliable as my iphone xr even in dark or direct sunlight.
I dont know if that is hardware or software problems.
73 hours of uptime. Random PIN for added security prompt has returned when Google Pixel support said it shouldn't after deleting and adding face unlock.
Taking my case ID back to Pixel support. I'm not sure the agent was right about face unlock not occasionally duping to PIN unlock. Very annoying if this is intended or not.
72 hour bug?

So my Pixel 4 XL face unlock did the same prompt for pin after another 72 hours. No reboot; no error or explanation why other than added security. I'm at 146 hours uptime.
I asked Pixel support again about this. They're researching but want me to do a factory reset now and get back to them.
