Question Fingerprint unlock - Xiaomi Poco X3 Pro

The Fingerprint Unlock feature on this phone NEVER works for me, Adding my fingerprint is really a nightmare, the fingerprint sensor is a joke. Every time when I put my finger on the sensor, either "fingerprint sensor is dirty, please clean and try again" or "only partial fingerprint is scanned" pops up and nothing was done. Does anyone use this feature successfully? Thank you for the info, regards.

Hey there.
I can confirm that the fingerprint sensor has some problems, especially if you use a cover.
And gives more errors when you try to use the big thumb - a logical thumb to use.
I have successfully recognized by the sensor the pointing finger and, as a backup the big thumb. The pointing has more rates of success.
Just try to randomly place all parts of your finger onto the sensor.

There are few phone in market has Finger print sensors - like One plus 2, Elephone p8000, UMI harmar, etc.. We wanted all the phone user should have a access to finger print sensor without the sensor, so we made the first app which can use the camera and act as a finger print sensor.
We made a simple application which can use the Camera Sensor and Un-lock the locked Apps.
If the Finger print is failed to detect, automatically the Pattern lock or Number lock will open and ask the password.
Unlock the app thru your fingers.
Finger prints are Encrypted by default.
Choose the option which way you want to unlock the apps ? Finger print ? Numbers or Pattern?
Requirement for Finger print - All you need a good Camera with Flash, I believe 8Pix Camera with Flash can do the real job.

Because i love having smudgy pictures i would use this alllllll the time...
Wouldn't it make more sense to try and use the back heartbeat sensor as a method to unlock instead of getting finger prints all over your camera?
Like rhythmic tap on heartbeat sensor or something...
I tried it and it wouldnt register the finger, for a while. i did but it took a long time. then it made me start over. so i tried it again and this time it didnt work. Its a good idea, just not there yet

Fingerprint Sensor Works/Doesn't Work Randomly

Hello, I set up my finger prints and turned on the service but have found that it only works sometimes. When it does works it is extremely fast and useful. It will work anytime I touch it and then a couple minutes later touching the sensor won't do anything for a while. Then it will randomly work again later on. Is anyone else noticing this?
I've been very pleasantly surprised with the fingerprint sensor on my S8+ unit. That was the only thing people complained about before the release of the phone, but mine has been spot on 19/20 times. Maybe add a few more versions of your finger or try from scratch?
Try adding multiple fingerprints on the same finger. I also was surprised how amazing the fingerprint works. Very sensitive and VERY fast. But I added minimum of 3 fingerprints on my right index finger

Had this happen the other day. Pull-down gesture did not work either. Had to restart the phone. Lots of bugs in this device at launch apparently...
Same thing had happen to me. After a while it just stops working and have to reboot. Anyone know how we can bring this issue to light so it gets fixed? I tried turning off power saving in case the phone was actually killing the system app but it didn't work. Any solutions other than constantly rebooting
I've had similar thing happen today. Most of the time placing the finger on the sensor will unlock it right away. Today, my finger sat there and sat there, no error returned, but no scan either. It was just doing nothing. I tried a few times and it started working again. I'm using the Canadian S8+.
When the fingerprint sensor is apparently stuck, you could check the sensor status in the diagnostics: *#0*#

anybody else problems with the fingerprint sensor?

Hey all,
I experience problems with the fingerprint sensor. It often doesn't recognize my finger on the first try but I need to try it several times before my finger is recognized. Or face unlock solves the issue and thus the finger print problem is avoided. I also deleted the finger print and set it up new several times but the problem persists.
Anybody else got the same problem?

Nope, my fingerprint sensor works perfectly fine.
Yours may be defective.
Take off the case from the phone. Make sure u scan ur finger correct.
If is not helping factory reset.
If is not helping call oneplus...open return due defective hardware
This finger print sensor reads much differently than what I am used to. For me it's literally a quick tap with my finger. If I hold like I would with Nexus 6p it won't read.

The sensor is really quite small and not perfect. I scanned the same finger three times (different parts of the tip) and now it works quite well. You will get occasional errors stating that the same finger has been scanned already, but if you keep trying it works
It's not a perfect sensor or even close, I've had to add a finger twice to get it to unlock properly most of the time. I add it as a new finger.

I bought the OnePlus 6 and I came from the OnePlus 3 and I ran into a similar issue. It helps if you input your fingerprint multiple times
For me its not that it doesn't recognize the finger, but sometimes it just doesn't even recognize that I have placed my finger on the sensor to check if it's mine. I have no idea why this happens
Mine works great. Sometimes I think it's even too sensitive, I turn the phone off and it comes back on when my finger is still in the vicinity of the sensor. Try to wipe it off with some mild water-dishwasher solution to get any dust/body oils off of it.

Are you running a custom kernel? I had this issue on Stock OS using Flash Kernel. Reflashing back to stock fixed it for me
My fingerprint recognition was always failing. The sensor was working because it would vibrate whenever I put my finger on the sensor but it never recognized it. I contacted OnePlus Support and the first thing they recommended is to see if there was an upgrade available. There was one - so I upgraded - not really thinking it would help at all. But miraculously, after the upgrade, fingerprint recognition works like a champ.
Try upgrading.

For me I had this same issue but not initially. The first 4 days I ran into zero issues. It worked every time. I then decided to start tinkering and installed the XXX mod. It wasn't quite what I was looking for so I decided to return to stock. At this point I flashed the stock rom via phone update menu. Then I factory reset and set up again. I noticed memory management issues and also problems with my fingerprint reader not recognizing my finger as easily. Re doing them didn't help. So I thought maybe I would use the fastboot method of restoring the software like the Nexus/Pixel roms. I did that and it flashed successfully but had the same issues. So I decided to manually flash each partition on both slots. Then I set up again. Still had issues. I figured at this point it was definitely a hardware issue because I felt I couldn't be any closer to a stock, out of the factory condition. But I was wrong. The msm tool that uses the Qualcomm drivers is the "Factory Image" I was looking for. It completely restored my phone to the condition it was when I unboxed it. I know logically there shouldn't be a difference but it flashed or fixed something on a certain partition that got changed when I was tinkering(I assume). So long story short. Try the msm tool if you think you have hardware issues before you rule out the software.
Fix-Fingerprint sensor not responsive
Entered to safe mode fixed the issue for me after a lot of trying to make it responsive.
Go into battery /battery optimization /hit the... Menu (advanced optimization) uncheck advanced optimization.
If on she is saving battery in sleep mode.
The issue you guys are describing is simular on rear sensors.
I did the above and it helped. Give it a try.

Asking for a favor from anyone in the Zenfone 7/7 Pro community

Hey! I'd like to ask a favor from someone with a Zenfone 7 in their hands. Could you tell me the driver name of your proximity sensor? You can check it by using Sensor Box (free on the playstore).
I'm asking for this because it seems my phone doesn't even recognise the driver and it just displays as ASUS Proximity Sensor, opposedly to other sensors that display their true name. Maybe I'm tripping and that's just it's real name, but I'm almost sure it had a different name before the sensor started malfunctioning.
I'll attach a couple screens. Thank you in advance.
Here's some screenshots from a borrowed Zenfone 7 Pro, as you can see it's named the same.
To be sure we don't suffer the same fate I did some tests to confirm that sensor is working.
@zcrubby Thank you! Indeed your sensor works well. I'll keep trying to figure out where to find the root folder of the proximity sensor driver to disable it, since I was able to get sensor disabler functioning but didn't do the trick with the proximity sensor. Would you let me know if you know something? Much appreciated!

Any luck in disabling the proximity sensor? I have a strange bug wherein every restart of the device causes the first instance of the camera to flip upside down and come up with the camera obstruction error. But once you click ok several times it's fine.

General An Interesting Solution To Fingerprint Scanner Not Working in AOD

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
