Hey there..
I've had the phone for a few weeks and like most of you I wasn't satisfied with the performance of the fingerprint sensor. After tying all the how-to and walk-through guides to no avail, I decided to give something a try and to my surprise the FP sensor is working flawlessly.
So, here is how;
While registering your finger, touch the sensor as Lightly as possible and keep moving it around till it's registered. While unblocking the phone don't press too hard on the sensor area, use the same light touch that you used to register your finger.
It's been working like a charm without the dreadful 'no match' error for over 10 days.
Hope this helps.
Too much theories, everyone say its, but this phone needs software upgrade indeed.

Give this one a try. :good:
I'll give it a try. Thanks.
I also hate the fact that this phone let's you register only 3 fingerprints.
No way
All the same for me. When you using FP for a continuous time (a couple of a continuous opening) it's working like a charm, but after a "hour" of a rest all problems comes again
That's the truth from me.

I have the same problem. It's absolutely horible in the morning, for the second day in a row had to use pin to unlock. After that - all fine for a hour or two.
Maybe working how a wind blowing as i see

Got it now
Since April Update the fingerprint sensor is a bit better but still needs improvement.
I found two things:
1) We got the habit to just touch the sensor and it unlocks rapidly with our previous phones with normal sensor. The fact is that is when you put you finger on the screen we tend to remove it rapidly or to put too much pressure that the sensor cannot read it. That is my personal findings.
2) Found a post on XDA A50 section but unable to find it now but the trick works for me. When you are registering your fingerprint as example fingerprint 1 put the same thumb from left and right hand each time. Example your percentage registration is 15% your put your right thumb as soon as it increases you put the left thumb and so on until it complete registration. You can use all the three slots with doing so and it increases the responsiveness of the sensor while unlocking. I used only two slots since my girlfriend uses one on my phone and it works very well.
Have a try and let me know.

Hehe yes... I trust her so it is ok
Pay attention please.
Here some tricks to try for FP speeding up.
As 1st, dlete all entered finger prints. After that lower the phone light at minimum (Adaptive Brightness keep ON and slider set to minimum).
As 2nd, form a three fingerprints with only one finger frequently used with such so light screen touching.
As 3rd, return to Adaptive Brightness and OFF/ON it on button.
After that my FP sensor react as a charm in any case. I don't use AOD. Just lock screen.
But i have made som goodness with my wish picture as a lock screen. I have made a light white circle with the dimension and a positin like a FP sensor so it helping me to light the FP area
Here is my picture so You can use it to form Yours own.

Nice one. Did not thought doing this surely it can help, but does it help also during the day when outside?
It could be just better on sunlight. Brightnes slider then jump to max
Report You that.
P.S. Same precission on dyrect sun as in the room or a half shadow...

I couldn't understand what you said in step 2 and 3. Can you please explain?
2nd: Add 3 FP but every FP with the same finger from various angles and just a soft, soft screen touching (not hard pressing) with Brightnes seted to min
3rd: After FP entering, go to Adaptive Brightness and turn it off and on to set the auto brightness vslue.
That's it.

Yes, I used your wallpaper. Kudos to you for coming up with such an innovative idea. But my FP sensor works the same with other wallpapers also. Not much gain in speed.

Sweet. Hopefully it's hacked with front camera access and the ability to enable it by holding the volume rocker to do the scan. Hopefully you don't wake up one day looking really ugly.
Lots to hope for LOL
It would be nice to have the camera key on the side though. There already a couple of face "detection" apps out there, not recognition though. Photofunia, in market, takes face and puts in various backrounds, works well

One example of the motion sensor is that when someone calls you, the Evo quiets the ringtone when it detects you've moved your phone with the intent to pick up the call.
It's actually a proximity sensor, used to turn the screen off when it's held close to your face. The feature of the ringer quieting on pickup uses the accelerometer.
So what does the motion sensor do?

The Light sensor via front of HD2 disables touchscreen of device when held close to face! The motion sensor is used for screen rotate and other apps that work well with phone positioning commands!

The light sensor has nothing to do with disabling the touch screen. Its used to change the auto brightness of the display. The screen shuts off when on the phone because its turned upright.
Well that's how it works on the evo. So I would think the same for hd2 that u mentioned in a evo thread...
It is turned off via proximity sensor not accelerometer

Ahh, but u can hold the phone next to u and the screen won't come on till u tilt the phone horizontal...anyway its not the light sensor...And yes a face recog app would be very cool to have...
People, people! Please!
1) Accelerometer: Used to detect changes in movement. Used primarily in Android for apps such as Bump, or to rotate the screen, or games such as Teeter and racing simulators (tilt phone like you're turning the steering wheel, etc.) Also known as the motion sensor.
2) Light sensor: Used to detect ambient light so that when the phone's brightness is set to automatic, it knows to increase or decrease the brightness of the screen appropriately.
3) Proximity sensor: Used to detect if something is near the speaker and of the phone. Mainly it is used to turn off the screen and touch input when it detects something near its front, and a call is in progress (aka, detects the side of your head near it, so your cheek doesn't accidentally push any buttons).
As for the facial recognition, yes, that would be nice, but what happens when you get a haircut? Put on glasses? Have a zit? Get a black eye? Swollen lip? Sunburn? Grow/shave a beard/mustache/etc.? That's the problem with these kinds of software, and why all computers that have facial recognition will always have a password or some other kind of backup authentication.

It's also a laptop and you still have the password login as a backup. Believe me, I used to cell them and had to reset the password every other day because bratty little kids came in and thought they were smart and tough by setting the camera login to themselves making some disgusting face, and the password to "toughguy" or "password".
Wow!!!!!!
is this app out yet? Couldnt find it on the market..

Would be pretty great!
Lol at the misinformation, thanks for clearing that up for our slower folk.
This is definitely gonna happen sooner or later.
It would need a backup method of course but if made properly it would be more general and little things wouldn't change the outcome.
I was thinking this...
You take 3 pictures the first time you open the app.
It merges them, aligns the face and sets a gaussian blur to smooth and remove imperfections.
Then it cuts out things like hair and eyebrows leaving behind the static parts of your face such as eye shape, nose, mouth, jawline and cheekbones.
It basically takes the 3 specific pictures of your face, and generalizes them, while keeping them relatable to every future pic.
I think its called interpolation, which gives you the perfect identifier, ultimately being used to recognize you.
Of course a setting would be needed to change how similar the face needs to be before being granted access but theres no reason it wouldn't work.
My other going thought is an app that learns as you go but it won't work as well.
nope again!

iTS AN OK thought of how it works but my HD2 can be of any position even flat down and as long as I am in a call and i put my finger over the light sensor (same as face, ear being close to sensor not letting hardly any light get to it)
the screen disables! I think many of you may not have the HD2 if ya didn't know that, don't let internet chat and gossip get in the way of the truth, truth is within the device when holding it, not hear-say. Also why would the accelerometer have anything to do with disabling screen when in an upright position? If one was to lay down in bed chatting on fone, my HD2 would un-disable screen... Try an app called mToolbox, it emulates what light sensor and motion sensor can be used for. I would say, light sensor can be more useful in many more apps than motion, motion works great with changing screen from portrait to landscape and movement in games.. An app to control ps3 via bluetooth using HD2's accelerometer feature would be useful, but for now, i have tweaked it to off, I have many older WinMo's and find using the screen orientation key much more faster and when i need it, it gets annoying when the screen changes at unwanted times and no matter how you calibrate any accelerometer, there are flaws to it depending on what situation one is in when holding the device (fone must be upright again to go back to portrait if fone was laying down) sorry for the long babble but I'm certain that the light sensor own's the screen shut-off feature on the HD2 for sure.. Quote me again any time!
Has anyone noticed that ambient display lights up upon receiving a notification but does not continue to flash like it did on previous nexus? Also it does not flash on upon picking up the device.....
I have ambient display turned on but to be honest I'm not sure my notifications even show once but I'm certain they don't show again.

Came to post this myself. It looks like Ambient Display pops up when you get the notification then never again.
Coming from Moto Display, super disappointed. I was prepared to give up the "wave" to trigger IR sensors and pulse my notifications... I wasn't prepared to give up the feature all together!
Running into the same thing. The ambient display should flash the time, date etc when picking up the phone . Maybe just a late software bug?
Not sure how many others have seen this yet...Notification LED. Mine is getting delivered today so I haven't been able to play around with it yet. It might help with the ambient display issue.

Unfortunately that doesnt help
The display turns on it uses the battery.
I hope they never "fix" it.
I pickup the device right hand let my finger touch the finger print sensor if I want to see the display.

Right and I say three things.
1) Why when you lift it is it supposed to turn on ? Did Google ever say? When you pickup you phone the Display should turn on, because we know you careless about battery life.
2) When you pick up you phone why is it so hard to brush your finger on the finger print scanner if you want to display on ?
3) You think every time the phone moves and the display turns on it is not going to use more current, drain the battery ?
If Google ever allows you to turn on the display with just movement picking the phone up.
I hope Google allows people that think 2) and 3) are true to keep this "feature off"

I'll try to spell it out for you since you apparently lack the capacity to do it yourself.
Ambient Display currently does nothing. It flashes once and is gone forever, which is completely useless. You LIKE it doing nothing. Fine. Then you can turn it off and it will still do nothing. You are happy either way.
There are people who like Ambient Display when it actually works. These people are not happy that it doesn't currently do anything. If it is fixed, then they are happy. If it is fixed, you can disable it, and you are still happy because you weren't getting anything from it in the first place.
Your twisted desire to hope something doesn't work because you don't like it is asinine.
Have a good day.

Hello fellow lenovo p2 owners i purchased this phone 2 days ago everything most things seem to be working fine apart from a couple of quirks. double tap to wake is hit n miss which is rather annoying but i can live with it in the hope future software will fix it. On another note i have noticed their is very faint red led light always on to the left of the speaker after i turn the screen off. Has anyone experienced this issue with the faint red led which when the screen is switched on goes off but whenever the screen is off i can see it light up just left of the speaker. I am concerned that this led might affect the battery usage in some way iff it is always on. should i take it back to the shop on account of this faint light always being on which appears much brighter in complete darkness. t
Thankyou all for reading.
That's the proximity sensor. Have you got any apps that use it?

Hi thanks for the reply the only app I think might be using it is Ac display but not sure.
OK fixed its a false alarm its definetly the app AC display which is using the sensor while screen off because i disabled the app and the red faint light vanished. the only other thing left is double tap to wake is fragile and needs about 10 taps to wake screen sometimes. Hopefully this is software related.
Why use double tap when you can touch sensor once to wake the screen?
not too sure but i prefer double tapping the middle of the screen rather than all the way up on a specific point where the sensor is.
Finger print is at bottom. Can also click it once with a non registered finger to bring lock screen up.
Kind of think dttw is redundant on a phone with front finger print sensor and physical home button.
To reduce the wear-and-tear like in iPhone home button...

As for me, I'll use the DTTW feature just to see the time and glance thru incoming notifications and if nothing important, the screen will turn off after 5 seconds... If we wake the screen, then, we have to turn off the screen "manually" (unless we set the display off timing to 5 seconds...or DTT-sleep is implemented...)
If we were to always "press" the home button, there is high change of "wear-and-tear" failure in the near future...
My iPhone 4 after 3 years, the home button failed due to "wear-and-tear" because too many double-click to get to the background apps...now the iPhone is running "virtual floating button"...LOL...
My current Note 5 home button seems to be very reliable which is now closed to 2 years ownership... But I'm not too confident at P2a42's front fingerprint scanner "durability"... Hence, I'll try to reduce the "clicking" actions as much as possible...
I wonder after warranty ended, how much is the repair cost for the fingerprint scanner... Should be less than 20% of the selling price...
Can see your point. I never own a phone 2 years lol so makes no difference to me. Don't think I have had a phone 12 months before either, just too addicted to em lol.

Never got that problem with nearly one month using it. Maybe you should review your screen lock settings.
Ok, so maybe this is an old post, but here is my problem, my A50 was unlocking on my pocket, just like mentioned on the title of this post, my problem was a human failure, I was registering only the tip of my fingerprint, meaning, anything could unlock my phone, so, I made a fresh recording of my fingerprint respecting all the positions, and now I can't unlock from my pocket or using a fabric between my finger and the screen, and no, I didn't have face recognition enabled
I have tried all possible combinations (with or without blue light filter, in pocket and outside, over and without fabric, in dark and light, etc.) and I have never been able to unlock the device with an unregistered fingerprint. Problems with unlocking do be wet, dirty or greasy finger but nothing else. And otherwise the fingerprint sensor behaves perfectly after all the recent updates, I have nothing to complain about.

This is a hardware problem, which Samsung is trying to solve as if it's a software problem. They keep tweaking it, but it will never work as should (look at all the complaints about the s10 fingerprint sensor). An ultrasonic fingerprint reader behind the screen works in ideal circumstances, but on a phone it's just terrible.
I register my fingerprint and after 5 seconds it doesn't even unlock anymore. It says it's not my fingerprint. I can understand that your fingerprint changes slightly over a couple of days (I had to do some DIY in my house and I got a couple of scratches on my fingertips), afterwards my S8+ would ALWAYS unlock, but the A70 just thinks, well hey that must be someone elses finger.
I'm using face unlock and I must say it works very quickly. I read comments everywhere about people who stopped using fingerprint on these Samsung devices. It was a nice marketing trick, but what a terrible idea.

Is this a software or hardware problem and how to solve it?

I was on the verge of returning the phone over how poorly the sensor was working, it was as bad as 1 in 5 touches working.
I've had a huge improvement by deleting my fingerprints and setting them up again as per this guide: https://youtu.be/X9y--nHmaco
Hope this helps.

Thanks for that!! Works a treat.
Register 3 times, in the same position you will use to unlock like the @chongo_au video above
Dont folow the screen tip when registering. It is misleading
Also, emove transition effect on biometry preferences
Try also register one of the three like this: first, put yout finger on power button, and then put your finger on the scanner

What do you mean by put your finger on the power button and then on the scanner?

1. put your finger over the power button (just to position, no pressing)
2. now put down your finger to scanner
why? because lot of people, when unlocking the device, do this movement, pressing power button first, and then press the scanner almost without moving the hand, using the right side of the right thumb
It is just a tip about positioning. It worked for me.

I got some tips to solve this problem, just moisten your finger a little bit, maybe you can lick your finger and then rub it with other finger, but don't let your finger dry completely (i.e. if your registered fingerprint is your thumb, then lick your thumb a little bit and then rub the surface with your index finger) and then place your finger to the sensor as usual. Hope this work on you too! And sorry for my bad English.
a70 fingerprint recognition
I also thought that it was the sensor Until I did a reset on my phone to remove some of the clutter I put in with Smartswitch
fortunately you don't have to reset your phone
-> first remove all your fingerprints saved!
->think carefully about the part of your finger that you will place in contact with the sensor!
->place that part on the sensor first covering it completely ..no need for too much pressure !
->keep your finger in this position for 3 seconds then follow attentively the direction for positioning ..each position 3 seconds
And here you have it, I am hitting it 100% of the time with dry or sweaty fingers!
->-> bonus it works in every orientation of you fingers even upside down!!
youtube ->A70 sensor work under all orientations!
Fingerprint in Android Q for A70 fixed
I have an A70, and had the same problem as all of you are having, with the fingerprint, but I have just solved it.
What you need to do is download samfirm, and look for the firmware, from Bolivia, with this date: 21/03/2020.
Just flash this firmware from Bolivia, with this date, and your fingerprint problems will get fixed.
it works fine for me
An easier solution is to first remove all fingerprints then reboot.
Clean you phone screen. Also wash your hands too.
When boot complete re-register your fingerprint.
Since you can register three fingers in total, register the finger you will most commonly use to unlock phone two times. Make sure you change your finger position everytime you scan it
The type of screen protector you use can also affect fingerprint scanner
Matt protectors fail the scanner.
