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?
Screen used as finger print reader

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?

The fingerprint capable Japanese and Korean phones have built in dedicated fingerprint sensors.

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.

Hey is there an apparently that allows you to have a lockscreen that is turned off with your fingerprint?
Sent from my ADR6400L using XDA Premium App
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.
Hello to all, am going to ask if anybody of you have a problem in TPs Touch Capacitive Pad? I used this app
Nav Debug Tool by HTC
http://forum.xda-developers.com/showthread.php?p=2511016
To check out this multi touch stuff in my TP (though I know before that it has a multi touch feature, I just want to check if it's working properly) but it seems that the pad has a problem. The problem was sometimes, it can register my touch and most of the time, not.. sometimes it can register the multi touch, and most of the time, not .. even the nav wheel has a problem which doesn't register the rotation most of the time. Is this a common problem in TPs or even Diamond??
I even use the signed os WM6.1 but still has a problem.. so I wonder if any of you guys having the same..
thanks!
It's been happening to me for about a year already as well. Seems like it's just defective. It resets thought after sleeping the phone and waking it. I'm not sure if it was because I used to use Sensor scroll or it's a little scratched up.
I hear the d-pad was a good conceptual idea but that is about it... I personally don't use the d-pad at all because of this, much less any of the buttons (to include the power button). On the other hand, from what I can tell about the d-pad "sensor" from using the NDT(Nav debug tool), it does seem pick up points but it seems to not like repetitive touches. It almost seems like the sensor overloads the processor to the point that it fails in terms of keeping up with the actual location that is being touched; if that makes any sense?

that made sense but why would HTC permit a buggy front pad???
You know, it seems many phone brands/cooperations come under fire due to lack of something or another; maybe proof of concept? Perhaps the debug tool is to blame? Or even the sensor degradation over time? One can only speculate so far before it becomes a volatile thought... Again, I point out the idea being good, conceptually. So, I don't know where that exactly puts us as being end users? Then again, I've never really had a decent experience with phones, much less with newer phones; my thoughts and expectations may be slightly on the negative/lesser side of things because of this.
I have the same issue. I used to use GScroll to flip pages in e-books, but finally it got so buggy I had to dump it (other GScroll features were almost impossible to use). I've used NavPad DBug. What I do find is that running the compact heaps command of SK Tools will temporarily fix things, at least most of the time. When I have NavPad DBug running, if it's logging compact heaps will clear out the traces. Somehow or other, it cleans things out when the nav pad gets confused or overloaded with inputs. But even compact heaps doesn't work all the time.
It would be sweet if the capacitative area really worked, but unfortunately it appears to get worn out about the time that you figure out all the things you can do with it. Lol.
Edit: I wonder if the device has problems distinguishing a single touch of your finger vs. several touches. That could really screw up the function of the device.
Hi
After downloading an app calles Sensor Box I saw that on my rooted device (sm-g3858) (stock rom) the orientation sensors, magnetic and gyroscope sensors are missing. Is there any way to add them? Are these sensors hardware based? GPS works fine for me so is there a way to implement these 3 mentioned sensor functions? Available in the phone are accelerometer and proximity sensor so I want to know if I can add the others by adding certain xml files

Sensors are indeed hardware. You can't simply "add" them. If my memory serves me, the only practical use of a gyroscope sensor is for Photosphere. Lots of devices are missing this. It's odd that your phone doesn't have a magnetometer. It's also odd that there's no orientation sensor. To be honest, I don't think that your phone is missing a magnetometer or orientation sensor. I mean, if you're watching a video or viewing a webpage and the display rotates, then clearly it has that sensor. And most phones have a magnetometer. Your phone (Galaxy Beam 2) is kinda a specialized device, so I guess it's possible that certain things common to other phones were omitted. If that's the case, it's unfortunate, but sadly, you can't "add" them via software.

thank you for your reply. Maybe that function is not activated? Samsung pretty much sucks when it comes to software support so maybe some files are just missing. Do you know where I could find the location of these files? The problem is that compass apps for example need that function (unless you know of an app that doesnt..)and I might not be suprised if Samsung just didnt add the files to /system

I really couldn't help you with that. I doubt anyone could. I would suggest, however, that you try a couple other apps. Phone Tester, Sensor Kinetics Innovations, to name a couple. Also, some basic apps that use these functions. Most compass apps use the magnetometer, and there's also metal detector apps (obviously, you'll need something steel or iron, not just any random metal). And as I said before if you're viewing a webpage or video or something, and you turn your phone sideways and what you're viewing changes its orientation, then you've obviously got that sensor as well.

I tried Sensor Kinetics and when I change the orientation the Accelerometer is effected. So basically the orientation sensor is the accelerometer in this phone. And I can also see that in the demo option. But anyway I tried several metal detector apps and there is 0 reaction. So I guess thats it. Thanks for your time.
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.
Hello,
This is my first post probably after 6-7 years.
In my Pixel 7 Pro [which is a little over one month and one week old] I have found the onscreen FP scanner does not always work when the phone is in AOD mode. If I touch the FP scanner nothing happens; it feels as if it is an image LOL.
Searched internet a bit and found this phenomena is a common problem with phones that have onscreen FP scanner [perhaps more specifically with optical scanner? I dunno].
Checked the solutions and none worked until I found out that if my default finger [which happens to be my right thumb] does not activate the FP scanner it has always been my left thumb that works perfectly fine. It is as if the Scanner was waiting for my other finger to press LOL.
Both my thumbs are clean/have same state of cleanliness during operation.
I think this could be helpful to those who probably scratch their head wondering as to why the FP scanner does not work in AOD. If you have more than one finger assigned, just try the other one.
This also raises a question to me [which might be lame], is Google doing it intentionally requiring the other fingerprint sometimes?
Agreed. Fingerprint scanner is unreliable regardless of AOD. Adding multiple fingers can help, but the reader is just wonky (that's a technical term)
It's worthless. Such an aggravation I just use the login code.
Don't know what you people are doing, my fingerprints (both thumbs) work just fine, once in a blue moon it might miss the first time, however I have never had a failed fingerprint unlock from either AOD or lock screen.
I never have issues with my fingerprint scanner on all 4 fingers I added
