Issues with Fingerprint Scanner - Atrix 4G General

Is anyone else having problems with the fingerprint scanner? I'm trying to set it up to accept my print but it won't scan it.

No problems at all. Set up quickly and easy.

swipe slowly. good swipes take at least a full second it seems. mine set up just fine and works for unlocking the phone.

Mine was shockingly easy to set up.

Thanks! That's all it took...

You don't really need to exagerate the swipe, but the 1 second rule is not a bad one to follow.
Make sure that the way you swipe to enroll is roughly the same as the way you swipe to authenticate. Holding the phone in the same way helps a lot.
Swipe from the base of your finger pad, to the tip of your finger.
Always use a pulling motion. Do not push your finger across the sensor.
You can actually unlock the device whether you pull toward the bottom of the phone from the top, or flip the phone around and pull the other way during the swipe. This can be very useful when the phone is in a dock.
If your finger crosses the sensor at a strong angle, you may not be able to authenticate or enroll. Remember that the finger should be aligned as indicated in the animation.
Enjoy! And remember, this is serious security. It's way beyond the pattern lock or a pin. And yet, it's easier to use than either. How often can you add security and make something easier to use at the same time?

How does fingerprint scanner compare to iPhone in terms of success rate?

I know that mechanically, the S5 fingerprint scanner works DIFFERENTLY than the iPhone. But I'm curious how it compares in terms of reliability. For many people, the iPhone fingerprint scanner works virtually 100% of the time, so it is very quick and easy to unlock phone.
How is it on the Samsung Galaxy S5? Are you constantly having to reswipe your finger and readjust your grip to get it to work? Or, once you get the hang of it, does it reliably work the first time, every time?
Especially interested in hearing from people who have used both the S5 and an iPhone touch ID.
..
In order for it to ever be as good as the iPhone finger print scanner would they have to make some hardware upgrades or would it just be work with the software?
It's awful. Hardly ever gets mine right and I've scanned multiple fingers multiple times.

The trick is to scan just one finger multiple times. For example, you need to scan your thumb 3 ways - swiping down with the phone laying on a table, swiping down the way you would normally swipe with one hand and swiping down at an angle. This way the scanner will work much better, because it will have registered your finger in all possible situations you might swipe

Yeah I know that and have done. It's just a crap fingerprint sensor. OP is comparing to the iPhone. TouchID works flawlessly.
I second the previous posters comment on Touch ID, it is unbelievably impressive. It's worth the extra configuration time when you choose finger print scanning. My worry is that this may be patented to Apple? If so, is there an alternative for Android?
TouchID is easier to use and more accurate.. Its like put your hand in your pocket and your thump on the button and it just works.. While on S5, you have to swipe and sometimes it doesn't work, won't use it for my lock screen, still would use it for private mode

No problem here, way better than the sensor on the Note5. Have you used one before? I wonder if your fingers just don't work well with them.

Go to setting, security, imprint and setup another finger, you can use the same finger if you like. Make sure if you are using a case on the phone that you setup the imprint with the case on. If you setup the imprint with no case, then put a case on your phone, your phone will read your finger differently, therefore it may not work correctly. You scanner should read your finger 9/10 times if not more
if it works that bad, delete all prints and RE DO
mine has yet to fail
i have set up my finger again, the problem im having is that i can access my phone by the power button thus by passing the finger scanner most times. Surely i should only be able to access my phone when my finger print is confirmed.?
You should just be able to use the finger print scanner and not touch the on button at all. About 99% accurate for me.
When you set it up, did you keep moving your finger on the sensor between presses (not during) to make sure it had a good cross section of the finger to recognse?
All is working fine now after the recent security update from google

How fingerprint scanning works on the G4 plus?

Hi,
I need to know something. I hope you'd help me.
On the g4 plus, how fingerprint scanning is working? the sensor is excited for finger's sense at all times or only when the phone's held in the hand ie when the phone detects a motion? Asking this 'cause I'm having some weird problem. My sensor doesn't sense my finger at all when I don't hold it in my hand. I just put a finger on the sensor when phone's absolutely still on the ground in sleep mode, not moving. But the sensor was unable to respond. I have to press it harder to make it detect my fingers. Quite irritating.
But the sensor properly detects and senses my fingers when the phone's in my hand. What could be the problem? Is the sensor defective or it's perfectly normal ?
It doesn't work when is horizontal on a table. If you press slightly harder, the phone moves (tilts "up" the top part a little) and it works.
Weird for me to test since I have registered only my thumbs. I never use it like that. On table I see the notifications and if I need to do something about them, I always lift the phone up from the table.
Mine (UK model) works just the same on the desk or in the hand. no added pressure required. maybe try re-doing the finger registration
Are you sure that the phone's in sleep mode when you touch the sensor? Just put the phone on table for 2-3 minutes and then try to touch the sensor without touching anything other than it. Could you please check it again... Can you unlock the phone?

Mine (IN model) works perfectly in both situations...

In that case, my replacement for the phone isn't unnecessary.
What I feel like when we move the phone a little then it activate s the FPS and it works fine.
But if the phone is stationary for some time and touching the FPS doesn't unlock.
So I think it's not a problem.
Mine works fine also... but I can't use the finger print sensor to sign in apps or remember passwords on the browser (I use chrome) ... I used to have a Galaxy S6 and it automaticaly asked me If I'd like to use the sensor for this ... but G4 don't.. can anybody help me with that? thanks

E-ink Lock Screen

Hello everyone,
So, I'm having a bit of a strange problem with my Yotaphone 2...
I did a factory reset on it a while back, and everything went fine, except now, when the screen is locked, I can no longer unlock the e-ink screen by dragging up the lock icon on the bottom of the e-ink screen. I have to use the hardware power button, which is a little bit inconvenient at times. I've spent quite a while trying to locate what setting got effected to make it not function, but with no luck. Anybody have any idea where I can turn this function back on?
It happened to me too, I think it was something related with the Lollypop update, but could be some setting that has changed and that I cannot find. However, I found that if I double tap before tracing the finger motion, it usually works. That's why I didn't look further into the issue.

No luck for me. I'm still on Kitkat anyway...
Looks like I might be stuck...

Actually, scratch that... after your double tap suggestion, I started randomly tapping around managed just once to get it to unlock from a screen touch, but have not been able to replicate the movement so it happens again. What movement exactly do you use to get it to unlock?
Update:
Seems to be some kind of sensitivity issue. I can get it to unlock about once out of every 50 swipes. Less than ideal.
I leave the phone with the E-ink screen facing up (to prevent the gyroscope from switching sensitivity to the amoled display instead), then press twice the lock icon, and on the second time my finger touches the E-ink, I drag it up to the center of the phone. It took a bit of practice but now I can get it to work consistently. The double tap is because if the phone has been inactive for a while, it enters sleep mode, and it looks like that turns off the finger gesture recognition. Other possible explanations are that maybe you don't press the screen firmly enough, or maybe you placed some plastic sheet over the back display and that reduces sensitivity.
I noticed that the unlock gestures on the EPD work only when the phone recognizes that you've it in the hand or you're using it. So I take it and I unlock it effectively. Trying to unlock when it lays down and you haven't moved it for a while brings to your experience.
Thanks to both of you for the advice... unfortunately, neither seems to be doing the trick. Just a caution for any other people who are thinking of doing a factory reset - it seems to seriously impact sensitivity for the e-ink unlock, so be aware.
I never succeed to do slide up unlock even within 1st tutorial. Double tap unlock was the only workaround for me. Also activated glove sensitivity mode.

Make lock screen easier to unlock?

Is there some way to make the unlock swipe more sensitive? Or a shorter swipe required?
Sometimes it takes me 4 or 5 swipes to get it to unlock, it's getting a tad annoying. No other issues with the screen, it just seems to need far too long of a swipe to allow the unlock.
I don't use fingerprint / pin / face unlock.

I don't believe there is, but why wouldn't you use any of the above ? They're all ironically extremely fast, the fingerprint unlock is probably the quickest out of any phone in the world. The face is also rapid.
You could maybe install another lock screen but it would probably be quite similar.
There is more than likely also a setting in the ROM which altered the length of swipe, not in settings but an actual value within a file.

My finger tips/prints get pretty tore up at work and causes finger print readers to be all but useless.
Not a fan of face unlock, too many situations that it would be inconvenient. I suppose I could maybe try a simple pattern unlock instead, I tend to open my phone is awkward situations sometimes and want it to be easy to get into. I have no security concerns.

Have you actually tried the face unlock? I wasn't completely for it, but it's very quick and you barely have to look at the screen, it's also surprisingly accurate.
Did you know you can register several fingertips? So unless your whole hand gets messed up? I used to do ground work and roofing, bricklaying so I know what you mean. Should be ok tbh.

I have the same problem, and it's not only unlocking the screen.
Sometimes I try to swipe down notification 4-5 times before it works.
On Lineage/Resurrection rom it's working like any other phone.
There is one more thing, this bug is inconsistent, sometimes unlocking is working like it should and slightest swipe unlocks the phone.
