Fingerprint lockscreen - General Questions and Answers

Hey is there an apparently that allows you to have a lockscreen that is turned off with your fingerprint?

I'd say no, since no current lcd has the capability to scan a finger print.
Sent from my HTC Evo 4G on the Now Network.

The Mtorola Atrix does it with hardware. It has a fingerprint scanner built in, i dont think theres another way.

There is one that's made to look like that's what it does, but it actually has some sort of trick - a hidden swipe along the side, or something.

you would need a biometric scanner in hardwired into the lcd to make it work! which is possible the technology is there just havent seen an android with this as a feature yet...

there is an app in the market called fingerprint screensaver... it will make ou scan your finger/thumb 3x times to get a match... then when your phone goes into sleep/screensaver/ or lock screen you have to scan your the digit you used to unlock it.. it will run a green line to scan your print then shows a little print animation like how the feds scan prints then it unlocks or says scan failed...it only will work with the finger you scanned... I use it on my incredible its cool...

LOL that'snot how that app works AT ALL

I actually developed a lock screen replacement in partnership with google that does exactly this. It looks exactly like the stock lock screen, except while you slide to unlock it scans and validates your fingerprint. We forgot to put settings to add/remove fingerprints(users) though, so anyone who slides will gain access. Sorry.

edit: Ha, i only just got the post above
I believe the phone with the most simultaneous multi-touch points available at the moment is the Lg Optimus 2X, which has 10. 10 is theoretically enough to scan a fingerprint, but touch points on android phones get very confused when close together or on opposite axis and, as mentioned, no LCD screen is capable.
The Atrix 4g has a hardware fingerprint scanner and is the ONLY android phone that can do this. Saying you can do it via the touchscreen is complete crap.

Is there a fingerprint security app ?

Hi all,
Is there a security app out there that allows fingerprint login, as well as unlock.
thks.....
I don't see how that can be possible? THere's no fingerprint reader on the HD2, unless its hidden very well
What do you think this phone is? a futuristic phone made in 2030? lol
How about ear-print recognition via multi-touch?

Before you mock too much, my guess is the original question is being asked because the LG eXpo phone supports this (albeit by a specific finger print reader built into the navigation rocker). It uses this finger print read instead of a password on the unlock screen (very cool).
I'm not sure whether this function could be applied to a section of the touchscreen on the HD2 as I imagine the specific finger print reading technology is quite different from a capacitative screen interpreting a press...
missing hardware, therefore impossible.
I don't think it's such an outrageous question.
Supposedly LG already implemented this feature, so it can be done.
Could fingerprint recognition software be developed based on barcode reading software?
If so, I think there might very well still be an issue with using the camera for fingerprint recognition if you'd want to use it for device access purposes.
Being "logged off" the camera would be logged off too I guess...
But hey, a lot of wizzkids frequent these forums...
Facial recognition would be possible I think.... er... it would also be easier if there was a 2nd front camera!
Honestly, I dont need it... but it would be cool I guess and some people would. I use EWallet for all my sensitive stuff...

erm.. actually japanese phones have had these features for the past 2 - 3 years already...
They also have facial recognition access.. and also various gesture unlocking features...
The screen can only detect areas os pressure, not the individual parts needed for fingerprint. The LG one I assume works by sliding your finger over the joystick?

You spot on! We just need a good developer to take in initiative.
The HTC sedna (which has its own section here) has a fingerprint scanner.

The iPaq pocket pc already did it BUT.. yes.. BUT that is hardware dependent. Fingerprint scanners are hardware depended. Don't ask too much.. If you are talking about using the camera as a fingerprint regconition scanner, I wouldn't rely on it too much.. its like using the camera as a name card scanner.. not accurate enough..besides, it would be a hassle to aim the camera to the finger just to unlock the device..
facial recognition is totally different from fingerprint sensor.
if you recognise fingerprint (which is far more complex than just facial expression) then you are probably going to recognise a dozen (or more) fingerprints to be the similiar one. For facial recognition application, this might be acceptable, but for fingerprint application, due to its nature/purpose of it, this will not be as it'll be a security breach.
so it has nothing to do with competency of the developer, w/o the hardware, regardless if you have a world class developer or s/w.
come on people, think!
as long as there's no hardware sensor for fingerprint scanning, there will never be a piece of software that's able to scan your fingerprint from a touchscreen, whether it's capacitive or not.
a touchscreen recognizes finger presses. but in order to get a fingerprint you really need the ability to read those small, fine lines of your fingerprint.
You guys are just too much! We can hack these phones a lot but not everything can be accomplished by changing a registry setting or installing a patch!
Looking for fingerprint recognition on the HD2 is like trying to take pictures on a phone without a camera. There's no app for that, just as there's no app for driving your HD2 to work or making toast with it.
Every single device that can recognize fingerprints (like the Toshiba g900 I used to own, and also the LG one) needs the dedicated hardware.
The capacitive screen is absolutely unsuited for this (see the explanation above) and I don't believe the camera can do it either. Barcodes are simple black and white lines for a reason. High contrast makes them look more or less the same in most lighting conditions so they're easy to recognize. Try taking a few pictures of your finger in different lighting: the difference between those pictures will likely be much greater (to a computer doing visual analysis) than between two different fingers in the same conditions.
I don't want to discourage thinking outside of the box, but this is a bit too far out I'm afraid.

(REQ) Two finger roatate

How hard would it be to make a app that runs in the back round that works like the new ipod's touch screen rotation feature,
For those who don't known you place a finger and thumb at opposite ends in the corners so top left, bottom right, and twist right or left, and the screen rotates that direction in which you twist, i and im sure others will find this great to have, i normally have screen rotation off, but sometimes need it for messaging and internet etc.
as you can see in this little apple video here.
http://www.youtube.com/watch?v=cZnSKvMP14A
Depends on the phone hardware...
But, in my opinion a useless feature. But then again a normally use the double tap to zoom on the browser.
Im not on about zooming, im on about rotating the screen, with out having to go back and turn it on and off from the home screen lol.

Did you even bother to read the OP or even the the thread's topic? He's talking about screen rotation not zooming.
I love how people declare ideas and apps as "useless" just because *they* wouldn't use it.

I'd like this feature too. I dont like switching rotation on and off, but i sometimes need too. Having it off, and use fingers to rotate would be a good solution.
Trouble in programming this is prolly that it is hard to not let it collide with other apps. (what if another app uses this multi-touch-gesture?) whitelisting apps is an option at this point in time, cause i dont know of very much apps that use this gesture, but they could become more popular with all the new multitouch devices out there

Maybe you misunderstood what he meant. The way I understand it, he only mentioned the zooming with double-tap to signal that he doesn't even use multi-touch to zoom within the browser; henceforth, he finds the idea of multi-touch rotation useless.
And to be totally honest, I find it useless too. The only reason the ipod nano has multi-touch rotation, that I can guess, is because they couldn't fit an accelerometer in such a small space and refused to change the dimensions. Either that, or just something else to cut their costs and make more of a profit.
Id love to see something like this. I too keep auto rotation off, but being able to rotate with a simple gesture would be awesome!

Did YOU even read my post?! I said why it might not work, then proceeded to post MY OPINION!
I could have said it worse like: Don't be lazy and leave it on and rotate the damn phone with your hand.
That ipod touch probably just does rotate by touch because it doesn't have an accelerometer to know when you've physically rotated the device.
Now a way of disabling accelerometer auto rotation would be nice for when I want to do something like read an eBook while laying on my side.
Actually, the iPod Touch DOES have an accelerometer, as does the new nano. The new nano uses its accelerometer to detect when you shake it for "shuffle on shake." WHy they couldn't use it to detect orientation of the iPod, I have no clue. But the iPod touch DOES do auto-rotate. I know this b/c my 1st gen touch does this for many of its apps (which I hardly use.... it's a glorified mac and apple tv remote now).
I think this could be a useful app. I don't like certain apps to rotate and as such turn auto-rotate on and off, but with auto-rotate off I sometimes wish I COULD rotate the screen in certain instances. Something like this would be pretty nice. It'd have to be light on the cpu though and not collide with other gestures (the only gesture I have seen on my Droid X that are multi-touch is the pinch-zoom.... all the other gestures are single touch ones) that are multi-touch.
I'd say go for developing this app. I'd be pretty cool PLUS you'd learn alot about how android handles gestures and such.
I would really like such a feature, iam actually working on an app/widget that turns the screen manually, because just sometimes you need it landscape but dont want to activate the auto-orientation...
I am with this idea 100%. I find the auto-rotate waaaay too sensitive & it rotates constantly when I don't want it to. So I turned mine off. But there are rare occasions when you want to rotate (like looking at pictures) and I have to go into a widget to turn it on & turn it back off after.
A manual rotate would be nice.
PS - A sensitivity thing for rotation would be nice too - ie, only rotate when you're 85 degrees + sideways instead of rotating with like a 15 degree tilt.
Mine will auto rotate at times (my g1 and iPod touch do this too btw) when I pull minor G's while driving (like hairpin u-turns or simply having fun in the curves ). Then again, these maneuvers are ones that can't be pulled in your generic automatic or road boat.

add my name to the list of people that would love to see this!
Hmm.. Would be a fun project to start learning android programming...
Now if only I had some time to spare...
This feature would be very useful, why?
- Auto-rotate : since it's called "auto", that means you can not control your screen with rotation. I usually lie on the bed and use the phone for reading, web browsing and I really don't want my screen from keeping rotating. You would say I should distable the auto-rotation, right? But I don't wanna keep doing that.
A manual gesture would be really nice and very USEFUL!
I think the sensitivity option would really be the best. Not saying I wouldn't use the finger way but I think the "auto" rotation should just work better.

My problems are that it is to slow and that when i am lying on my side surfing it auto rotates.
I am actually trying to find a way to switch it manually but all ways i try wont work

[Q] Gestures?

I was browsing through all the garbage on my phone with Titanium Backup and found "Gesture 2.2.2"
Is this just for things like pinch to zoom?
This is a really cool feature actually.. However its not on the US version. This was one of the selling points for the Optimus 2X. I believe it was imbedded in the LG's andriod overlay.
It basically uses the accelerometer to FF/RW, scroll text, and move app short cuts to different home screens by simply tilting, or tapping the phone. You could even hang up by simply turning the phone over (screen facing gound).
I hear there is a CM Rom that will use this to set up gesture/shortcuts to open apps from the lock screen. This will be even more useful especially when driving.

Yes, and it is really dope but if we didn't have a way to access it I don't get why it would be on our phone.

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.

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.

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.
Sent from my Pixel 4 XL using Tapatalk
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?
Sent from my Pixel 4 XL using Tapatalk
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.
