Facial recognition? - LG V30 Questions & Answers

Just started using it today. Seems like it works okay so far. Anybody else use it? Have you been able to trick it? Just curious about how well it works and security on it.

I find it not working correctly more often than not, however, that is because I only really use it while my phone is lying down, so the angle of my face might be tripping it up. I can't imagine what it will be like on the iphone x where this is the only way to unlock the phone. Holding my phone up to my face is not how I want to unlock my phone every time.

Yeah. I still have the fingerprint set up and mostly use that. True, I have bought iPhones too but I really wasn't interested in the X at all.

I redid the facial recognition for face unlock and I am now finding it is more accurate than before. Win!

**Yes i was being stupid, found it
Am i being really stupid, but i cant find this feature at all.
Im sure i saw it on set up but cant find it again now.
Andy ideas chaps?

Face unlock option gone?
Sorry for bringing this old thread up again, but i wanted try the face unlock option recently and i can't find it anymore.
I've set it up when I got my phone but switched it off till now.
Does anybody have the same problem? It it possible LG removed the option with one of latest updates?
Cheers

Nevermind, i've found it. Apparently i've removed lg face recognition from trust agents...

[Q] Question about NFC tag activation

Hi guys,
Desire S user here, currently looking for my next phone and seriously considerin the Experia S. I have a question about the NFC operation, which I can't find answered anywhere else.
I understand that the default for the phone is to only interact with NFC tags when the screen is unlocked - so that you can't "accidently launch an application". Is there any way around this. The reason I ask is that, when I get into my car and put the phone in my screen-mounted holder, I will want to activate GPS and Bluetooth and launch Sat-Nav, but don't really want to have to manually unlock the screen on the phone first.
I hope this question makes sense.

There is no way. It is a limitation of the framework AND always having NFC enabled will drain battery.

Thanks for the quick reply - I suspected that would be the case.
How are people finding this whole NFC thing? Does it work well?
I find it very useful especially when I get home or out.. I've set up two tags to work with what I desire.. Unlocking the screen is not that big deal.. Takes a second

You just need to activate the screen,there is no need to unlock the screen.

That's not correct, I do have to unlock it to get it to read the tag. I have just double checked this now and confirm it.
On my Nexus S with Gingerbread I used to be able to just wake the screen and it would read even if locked but when I upgraded that to ICS, unlocking was required. I assume they also introduced this in the later updates to GB that we have on the XS
I agree it is slightly annoying as putting the phone in my car charger wakes up the screen for a second anyway so having it then read the tag was very handy. Now I have to unlock it first.

glitchy face lock?

has anyone enabled facelock for your LTEVO yet?
I've had it running since yesterday and very often when I try to unlock the phone it'll try to use the camera but all i get is a black screen then it reverts to the alternate pass code.. this'll happen maybe... every third time? i suppose it may have to do with the camera process running in the background...
anyone else sharing my pain?
I use it but I haven't got a black screen from the camera...
I've been using it since I got the phone and I've only had that happen 3 or 4 times seemingly when I had a lot of stuff already running.

No problems here. Freakin fast as hell unlocking

I do get that too occasionally unfortunately.

Ok I am getting it too...Maybe one out of ten face unlocks will be just a black screen instead of the camera working.
Depending on the lighting it is 50/50 for me.

Lighting has to be somewhat decent, this feature doesn't seem to work in low light. I recommend you all use the 'Improve face matching' feature in different types of ambient light.
Mine unlocks very fast, quicker than I could type my PIN, if the lighting is decent.

Works flawless on my phone, but as a note:
I don't like it, its unsecured. In days where Facebook is famous, anyone with a good picture of you can unlock your phone, even by holding a picture of you they got in their phone close to your phone...

Agreed...but it's a pretty cool feature
Too bad there isn't a way to combine security features, for example, have face unlock plus PIN or pattern. Might get annoying in practical use though.
I'd love to use it but it won't recognize me with glasses on and I won't take them off everytime I go into my phone lol
How do you enable this? Or is it a separate app from the Play Store?

Lucky for me, I'm not famous. Anyone likely to have my picture would also likely return the phone to me.
Since I haven't bothered with using a screen lock in the past, maybe I'll try it.

Under improve face matching, you can have more than one picture to improve recognition, I took one with sunglasses on and one with out and it works.

Also, try it under different types of lighting and backgrounds. I've been surprised sometimes when I've been in less than ideal lighting, it still recognizes me.
Of course, I haven't tested with someone else's face.

Can i root if so how?

It was repeated all over in the G5 section, the only unlockable version is the european H850.
Also the H830 has root and twrp, but these are the only two models.
Thats dumb.
Sent from my LGUS992 using Tapatalk
One has to realize that the developers who courageously "get root" for us do so on their own time. Not only that, on their own dime as well. In the trial and error process of unlocking the bootloader the risk of nuking their devices is high (and quite a few developers have nuked this model and others). And they go and buy another, so they can continue development. This gets very expensive.
And most importantly, with devices like the G5 - it takes time.
So while it's easy for one to respond "that's dumb", etc - I guess the above points are completely disregarded. Or perhaps not even known in the first place.
Most importantly, we are at the will of the developers. If they feel they are being disrespected, amongst other things - it would not be unreasonable for them to halt development. Please keep all of this in mind.

I understand all that they go through and are doing and i appreciate it, i meant no disrespect. Im just saying its dumb that lg doesnt let you unlock the bootloader. I came from a moto x 2014 and all i had to do to unlock the bootloader was sign up on a website and do some other stuff.

Its the most talked about in the social media in the few years ago!
At this point, the h830 and h850 are the only models that can be rooted due to being able to unlock the bootloader.
Hey guys, just one question for those of you who already have root. Didn't want to open a new thread.
When using Nova launcher, are you able to unlock the phone without it requesting a pin to be entered?
I really need this answer, going nuts with a stock launcher

Under Lockscreen I selected "None" and never have to enter a pin - I do use Nova, but I'd assume it would be the same with any launcher? Unless I'm completely missing the point here :laugh:

First of all thank you for responding
Well the point is, with LG stock launcher you can set up pin protection but it works in conjunction with the fingerprint reader meaning that when you unlock the screen with fingerprint phone is not asking for a pin entry. You are however able to double tap to power the screen and then enter pin to unlock if for some reason you do not want to use reader.
Let me ask again Are you able to do mentioned above with Nova and root? Can you maybe test for me

Good grief, what a pain to set that up :laugh:
Sometimes I can unlock it by just touching it with the finger I set up, but other times I get "Unable to use fingerprint" and have to use the pin. I'd say it's about 50/50
No idea why it sometimes works and other times doesn't, but I'm removing the lock again now ... way too much hassle

Hey man, I'm also using Nova Launcher on my LG G5 H860 (no root tho - obviously - woe is me!), and I use the finger print scanner AND a pattern. I think LG suspect that the fingerprint scanner alone is not enough security, so they make us use a pattern or pin on top of that. At least that's my guess since I was immediately prompted to add the pin, password or pattern after setting up my fingerprints. Also, upon rebooting, EVERY TIME I have to put in my pattern. The fingerprint alone is not enough to gain access.
I'm guessing it would depend on the ROM you use, not particularly the launcher. But let us know how you go... Have you rooted yet?
Nice avatar BTW. \m/

It's actually a backup option I think, in case when fingerprint reader fails. Makes sense
System is not letting other apps take control over the phone even though they are listed as device administrators. It's a new security measure introduced with MM.
Of course everything changes when you have root privileges
I've rooted the phone yesterday. Nova can now unlock the phone with just a fingerprint. Also installed the Viper audio mod and deleted a few system apps.
Right now I'm investigating how to prolong the super brightness mode so it can last longer than lousy two minutes
Glad to hear someone appreciates the sound of perseverance \m/ \m/

The PIN is, just as you said, a backup security measure. If you're rooted you can go and download a fingerprint add on through Xposed.. that means Only your fingerprint is needed to unlock your device.

Don't have G5 so I can't test or even know if what I'm saying is correct, but I was looking through the G5 git tree and saw the super brightness mode seems to be called HL_MODE standing for LGE_HIGH_LUMINANCE_MODE, there's referenced to it in the code, you could probably edit it there then compile and it will most likely work, however it seems it's also with references to the kernel so you probably gonna have to edit both the kernel and ROM simultaneously to make things easier...

Biometric not allowed

Has this happened to anyone? Like after a couple of hours of inactivity, it sometimes requires you to enter PIN before allowing users to use biometric unlock method. It says ' For your security, use your PIN to unlock your phone. You can use biometrics next time.' As shown screenshot attached below.
The weird thing is, this happens, sometimes it doesn't, and biometric unlock works fine without needing to enter PIN again.
Not a big issue, but kinda annoying needing to enter PIN from time to time
Yeah, I get that every now and then, too. Guess it's Android's (or Samsung's) way of making sure someone hasn't managed to fool the fingerprint or face unlock.

Greetings,
My S8+ (Oreo) is doing the same since day 1. My S5 (Marshmallow) was also doing it, it was asking for password and not allowing use of fingerprint from time to time. Many people have the same issue but no solution / reasoning explained yet, I believe.

This isn't an issue.
It's a security measure taken time to time to prevent unauthorized access.
I disagree with "This isn't an issue." If it is driving me to turn off all my security because it won't allow me to disable it, then it is an issue. I've read the same sentiment from others.

^ comment makes no sense.
The stupid feature Google has introduced, is randomly demanding PIN instead of fingerprint. It will happen every couple of days or so, even when phone has not been restarted. You might have used it 10 minutes ago, doesn't matter... you will be asked for PIN and it says "use biometrics next time". It's so arrogant, and takes away control of our phone security. They are treating us like children. It's condescending and disrespectful.
The thing is, we can already choose to have no pin if we want, just swipe to unlock. So why can't we have biometrics ONLY without pin? Because we can't have nice things? Why?
It's the worst thing about my new phone by far. I will never stop looking for a way to get around this brain-dead "feature". How I unlock my phone should be up to me, not some crusty old Android developer sitting in a dark room, dreaming up ways to piss people off. If anyone knows how to stop it asking for pin, and use biometrics all the time (except after reboot) then please share knowledge.
"Its a Feature, not a Bug"
The fact that this is a feature rather than a bug does not make it okay. In fact, it makes it worse. It is a problem when a company tries to force its way upon me and upon a product I own and I have zero ability to do anything about it. If its "for my security" then it is MY choice to decide not to be forced to put in some pin at random when I have a perfectly good fingerprint that works just fine. I am not personally worried about someone cutting my finger off and revealing the occult secrets hidden within my phone, so I should be able to turn this off. If you try to force me to do something and make it impossible to get around, I might just leave your stupid platform forever.

Question Fingerprint Sensor not only bad, but unsafe?

I've had my share of grief with the fingerprint sensor on my Pixel 6, but it's totally usable and I was generally fine with it. Until I realised yesterday that all that oh-so complex and safe AI security procedure that allegedly makes the sensor so slow is complete bs.
I was sitting next to a friend who had never used an in-screen fingerprint sensor before and he wanted to mess around with it. After like 5 seconds he unlocked the phone. His left thumb was accepted by the phone. I was in utter shock. He was able to unlock the phone every single time without any problems whatsoever. So I thought ok, this might be rare, but there is a tiny chance that two people have very similar fingerprints. But needless to say, I was not able to unlock his iPhone with my fingerprint.
I have a few things that I dislike about the Pixel, but this safety concern feels major to me.
This has been recently publicised. There is a chance that other people may be able to unlock your 6.

it sure has been reported before but seeing it from others with the simplicity to bypass it is not just scary but hopefully embarrassing for Google and I hope they fix this.

Wow, hadn't heard about that yet. In the past I've heard that those simple face unlocks can be tricked by as little as a picture of someone, but I always thought fingerprint sensors would be precise and safe. Well, leave it to google to mess it up I guess.
I thought google hardware would be worth something in 2021, but this phone does not feel good at all.
Scary potential security problems indeed...
Did you have Smart Lock enabled? Did it actually scan the finger (i.e. did it get really bright on that part of the screen). The screen shows the fingerprint icon even when the phone is unlocked.
I didn't realise it was unsafe as well as being completely useless.
I have a use my pin to unlock it 50% of the time.
It also uses a CCD (i.e. camera) to read the fingerprint, so in theory, a picture of your finger should trick it into unlocking.
