If someone wants to buy a brand new fingerprint reader I have one for sale... I ordered a new one and than fixed the problem trough software and by now I've already sold my LeEco and don't need the reader... This offer is mostly for Europeans (because the posting cost outside EU) I've bought it for 5€ and will sell it for the same price if anyone is interested...

My finger print no longer working :( only 2 days. I have many roms testet cn cm mokee team spain etc 15s 16s 17s 18s 19s Indien Version etc..... Any idea? Or is a defekt? Sorry for my bad English I'm from Germany
[LeEco Le Max 2 Guides, News, & Discussion] vanguy2009:
I am using stock 17s cn.

fingerprint sensor using my left finger takes 2-5 seconds (multiple trials) before phone unlocks. using my right finger phone unlocks first try within 1 second. I re-captured my left fingerprint and it seems to work as fast as right side for the day and the next day its back to slow reading. My friend's OPO3 works instantaneous left or right hand fingers.

with the OPO3 the fp sensor is in front so you can see it and can align your fingers correctly each time. The Leeco le max 2 its at the back and finger placement is not consistent. I noticed my right hand is more consistent in the finger placement than my left so I think thats why it works better with my right hand. In any case the sensor is still slow at around 1 second to unlock but its still faster than the iphone so its good enough.

Btw also fp sensor works even if phone is asleep ie when I wake up in the morning the fp sensor works, faster is 1 second unlock, slowest is 5 seconds (multiple retry)

I know there has been a lot of discussions floating around reg the Le Max2 finger print sensor not working. I am complaining about the same thing. Some suggestions have been provided to fix - including factory reset, recalibrating the sensor, version update, replacing the phone etc. But none has seem to solve the issue. I have tried all of them. Is there really a solution for it? Is Le answering anything?
[LeEco Le Max 2 Guides, News, & Discussion] kakagi:

Is your Le Max 2 Fingerprint scanner still working?

Hi there,

Since your last post, is your Le Max 2's fingerprint scanner still working using your "techniques"?

Thanks,

Eric
[LeEco Le Max 2 Guides, News, & Discussion] abufrejoval:
Yes, not always instantaniously, rarely not at all, but generally OK.

Once I lost the softkeys (totally erratic touches) and the Sensor stopped working, too, until I rebooted.

Hello

I have just received the phone x822 and the fingerprint sensor is not working at all or detecting any of my fingers . the phone came pre-installed with 5.8.0.15s and i have tried 5.8.0.16s and 5.8.19s downloaded them from here

http://forum.le.com/in/eui_detail.html?euiid=209

don't know if its Chinese or Indian version

but still same problem as long as factory reset and calibration of the sensor didn't solve it. Can this be a software problem as most of you are referring and some users say it only works in EUI 5.6 m should i try this or not ?

or its a hardware fault ? i need to know for sure before i open a dispute . Any help would be appreciated. thanks in advance
[LeEco Le Max 2 Guides, News, & Discussion] kakagi:
go for a replacement if possible if after factory reset and finger print calibration sensor did not work for you. i have the same problem and replaced the phone as it comes with 10 days replacement warranty from the e-commerce site where i bought it. replaced phone is working till now but do not know how long it will work :P because i have seen few sensor goes dead even after 15 days or 1 month working.
[LeEco Le Max 2 Guides, News, & Discussion] IvoRodc:
This fixed my fingerprint scanner

I had the same problem with the fingerprint scanner what I did was flash the QFIL onto the phone and problem was solved.

You can find more info about the QFIL in this post http://xdaforums.com/le-max-2/how-to/guide-hard-brick-fix-qualcomm-hs-usb-t3492949

I tried Resurrection Remix CM13 but the storage is locked at 16GB.

Mokee has a bug where the fingerprint scanner stops working 5 seconds after the phone is locked, even the version released today has this problem.

Hi,

i have the same problem.. initially after recived the smartphone i flash the cuoco92 rom and the fingerprint it worked but after flash lemadmax rom has stopped working.

i have try all tips (re flash cuoco92, ledmax, chinese stock rom include "flash the QFIL") but still not working.

It has a week old can someone help me?

Hello,

Try this method:

Go to device/persist/data/Fingerprint and delete all files.

Download https://mega.nz/#!xIcU1JLL!bRMBOA89gJfv8OZ9U7nHrSgd-wcvDDVbow34HtDvu7o and paste the 4 extracted files in the folder.

It works for me with my X822 mokee rom.

PS: I received my phone with stock rom and the fingerprint was already down ...
[LeEco Le Max 2 Guides, News, & Discussion] onecryon:
unfortunately it did not work, I replaced the files, rebooted and tried but nothing changed. I tried the "calibrate fingerprint" and restarted but even so nothing.

thanks anyway
[LeEco Le Max 2 Guides, News, & Discussion] Steve-Austin:
In fact after rebooting, it doesn't work anymore, I have to calibrate the fingerprint again ...

Anyone find some solution? Its work good 1 day on Indian 019s rom. After that i flashed cuoco92 020s rom and its stopped working. Also i try with Mokee and RR and same thing..nothing works, try to get back on 019s indian and problem is not resolved...I am sure that there is something with drivers for FP
[LeEco Le Max 2 Guides, News, & Discussion] john707747:
I had this same problem for the last month. The sensor just stopped working, I tried everything to fix it. It just started working again the other day after I took alcohol and a lint free rag and cleaned the sensor for like 5 minutes. After that, I recalibrated and it began to work again. I cleaned the sensor in the past but this time, there was absolutely no way there was any residue on the sensor when I recalibrated. Give it a try. Nothing to lose.

How to recalibrate the FP ?

[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
After 4 days of my fingerprint sensor stopped working :( Do you know where I can buy sensor? On Aliexpress is only one for 43$.
[LeEco Le Max 2 Guides, News, & Discussion] midirt:
Mine stopped working yesterday, after 2 weeks. Calibration proceeds as normal, but can't add fingerprints or unlock, it doesn't react to the finger at all. No vibration either.
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Hey midirt... And also all the others with FP issues,

When you go to the fingerprint settings you can choose the FP to work as button for the camera. After this open the camera app (i have only tried it on Madsurfer MadMax, so eui based Rom) and try to make a pic. Please let me know what the reaction of the camera is. On my device camera is taking pictures like every second, after i hit the fingerprint sensor...

So if your phone is reacting like mine I'm thinking it's a hardware problem.

But if the camera is working like it should be I'm pretty sure that it's a software bug. Same thing if the FP don't react at all.

I'm no developer but I'm fixing hardware issues as a hobby. So I'm trying to get behind the mystery of this FP bug. If it's really hardware related then maybe I can find a way to fix it. Problem is that you don't get to many information about the fp sensor cause it's only a module from qualcomm.

Also interesting: I'm not sure but i guess there should be a way to get a log file what happens when the sensor is touched. If a couple of guys with working FP's and also another group of people with FP issues were able to create such log files, we can compare them. Like I said before I'm no developer and don't know how to handle the softwarething...

Should also help to understand if it's software or hardware problem.

Just a thought... If I'm wrong please correct me! ;)
[LeEco Le Max 2 Guides, News, & Discussion] onecryon:
Fp from camera dont work :(
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Hey guys...

Believe it or not my FP is working! It wasn't working since the day I received the device! ;)

Hopefully the steps i take to get it working will last for a while. If so than it will work without flashing a rom or setting the device back.

I need to test it out on a couple devices. But since my English isn't the best i will test it with a few German guys first. It's easier to explain the steps in mother language. ;)

I will let you know if it works...
[LeEco Le Max 2 Guides, News, & Discussion] Supertacomonkeyexplosion:
So you narrowed it down to a software issue?

( Your English is fine BTW :) )
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Im pretty sure. Like I said before I'm no developer but I'm fixing hardware issues on mobile devices as a hobby.

I will try to post the results of the research from the last weeks. Maybe we can find a solution for the problem together... ;)

[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
I checked it and actually when I turn on "tap to capture photo", the phone takes pictures every second. After several restarts, the phone itself does not take pictures, sometimes he reacts to every touch of the finger (rare), but usually phone detects one of a few touches (usually 4-8).

This means that my sensor is working or not?
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
I'm thinking that most of the FP sensors are working. So yes your phone should be fine.

Are you able to set new fingerprints? Or does the FP don't recognize anything when you try to set up new FP?

On my device there wasn't any reaction at all when I was trying to activate the fingerprint sensor.

Right now I need to compare a few things between the Le Max 2 from my girlfriend and my own device.

Funny thing is that my FP is a beast at the moment! Working 100% since I was able to "reactivate" it.
[LeEco Le Max 2 Guides, News, & Discussion] a_pollio:
Hello, since I bought my leeco max 2 the sensor never worked, neither with the stock rom nor now with the mokee MM. He does not even recognize my finger, he's dead completely. What would be the procedure that should perform ????. P.S. And tried to enter go to settings, apps, all, but it does not even appear to me: com.qualcomm.qti.biometrics.fingerptint.service! What do I have to do to make the fingerprint man work ?????

[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
Same, taking photos works, but there is no reaction when adding the fingerprint. Although today taking pictures by pressing the sensor works much worse. I have to click at least a dozen times.
[LeEco Le Max 2 Guides, News, & Discussion] Schranzfreak:
making pictures with the sensor works for me. but adding a new fingerprint stops after one try..
[LeEco Le Max 2 Guides, News, & Discussion] ajoesmith:
So what have you done to reactivate it lizard82?
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
So I've taken some screen shots to make things easier to understand.

Go to app management, first row named all and scroll down till you find

Scroll down to battery button and tap it. You see all processes and services implemented in the firmware. Like I explained in a previous post.

So go fingerprint management and delete all prints. If you wasn't able to set one before skip this. I wasn't also able to set one since day one.

After that hit the calibration button on the bottom of the fingerprint management site.

After this go back to the app management and find com.qualcomm.qti.fingerprint.biometrics.service again and wipe the cache and data. Also push the button to force stop the process.

Now you can freeze the com.qualcomm.qti.fingerprint.biometrics.service with

Titanium Backup or any app. I use Titanium for years now, so my choice. Also do backup of the fingerprint process you freeze to make sure that you can get back to the working point before if something went wrong.

That's what works for me. But as can see there are a lot of processes and services that are running together. But the biometrics point seems to be the bad point. On the Mi 5s that is also the process which leading to the overheating and battery draining problem.

You check if the sensor is recognizing anything also with a logcat...

That's where I'm standing now... Like I said, need more research to clarify things out.
[LeEco Le Max 2 Guides, News, & Discussion] ajoesmith:
Thanks Lizard82, i havent got mine yet, hoping it will arrive on monday but if i do have a problem ill try this out, thanks for being a great detective!
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
If your fingerprint is dead when you receive the device can you do a logcat and please let us know which firmware is installed on your Le Max 2.

Since most of our smartphones are already rooted and running different firmwares.

Like I said I'm no developer but repairing smartphones or replacing parts for quite a while now.

I'm just trying to get behind this fingerprint mystery myself.
[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
Ok, I tested that and now I cant even take photos by the fingerprint sensor. If I freeze "com.qualcomm.qti.biometrics.fingerprint.service" process, sensor completely stopped working.
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Ok... Have you freeze the process with Titanium? If so unfreeze it and delete data with using Titanium. Then reboot device
[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
No, because only paid version of Titanium have "freeze" option. I used "Disable Application" app. After unfreeze and reboot phone, again I can take photos.
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Ok. Haven't noticed that you can freeze and unfreeze it your way. Good to know. So camera is working without problems!? Then try to set up new FP.
[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
I think that taking photos by fingerprint works even better, but still its random. Cant add a fingerprint, nothing happens.
[LeEco Le Max 2 Guides, News, & Discussion] a_pollio:
I can not register any finger and it does not even appear in the list of app what you mention of Qualcomm. etc etc. Go screen

Man whats is the point of this? Does your fingerprint work after this? bcz this is the explanation how to stop the finger to work. When u unfreeze again are u able to add finger?
[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
So what, if I can take photo by touching fingerprint scanner (about 70-80% efficiency), this means that there is a problem with the soft or hardware?

Hi from Austria!

got my X829 last week - till yesterday total killer for the money - now the fingerprint reader apparently broken in multiple ways

1) most of the time the scanner doesn't even react - maybe 1/50 it works (then it mostly unlocks correctly) (adding a new finger when the scanner allmost does nothing is rlly fun) (calibration, stopping the process, deleating its data restarting does nothing)

2) yesterday, right before the scanner went dark like i described in 1) i got multiple false postitives from 2 different buddies within 5 minutes

3 and funniest) today early in the morning - i was reading the paper, phone was locked for about 15 minutes - it unlocks (fingerprint unlock on phone still active) without any doing on my side (i'm just asuming this was the fp-reader)

phone runs 16s stock and i read this should be a good performer on the fingerprint side...

given the curious bugs - u guys think its i software problem and i should try RR or lineage (was trying to avoid it till (if and when) nougat sources are out for working camera)? or sensor dead and i just should accept it?

ed: shame on me for not reading the whole thread first: tried using the fp-reader as camera trigger and mine also shots endless photos as mentioned by Lizard82
[LeEco Le Max 2 Guides, News, & Discussion] trugoj:
Another fingerprint dead?

Three weeks ago, while deleting the recorded fingerprints and adding them again, my fingerprint sensor stopped to work.

Previously, when putting a finger on the sensor, I felt a short vibration. Now I don't feel anything.

Ii tried almost all the roms (Crisbal, LineageOS, Mokee, SmallEUI, Cuoco, LeMadMax, ResurrectionRemix, several stocks, including flashing the "unbrick" ( on androidbrick .com the page is leeco-letv-x820-max-2-qdloader-9008-unbrick-twrpguide/ ), but it doesn't work.

I also tried these suggestions on a greek forum, myphone .gr - there are several topics:

/forum/showthread. php?p=7048130#post7048130

/forum/showthread. php?p=7067500#post7067500

/forum/showthread .php?p=6950610#post6950610

but my fingerprint sensor still doesn't work.

I am convinced that it is a software problem like Lizard82 explained , and I am also missing the application com.qualcomm.qti.fingerprint.biometrics.service (I am currently using ResurrectionRemix 5.7.4)

Which is the apk name I am missing? Does anybody have it? Where should I place it? in /system/app or /system/priv-app ?

[MENTION=7989046]to[/MENTION] anybody installed TWRP 3.1,:can you please make again a backup of your "firmware" partition and share it? I would like to try to restore your backup...

Many thanks for any help. I am quite desperate!

Hey guys,

I'm having problems with my Internet connection for 10 days now. Seems to be a problem with Dslam / Ports on Providers side. Hopefully it will get fixed in the next few days. Until connection is fixed I'm unable to go online as I like to.

But I'm still trying to figure out what caused the FP problems.

For now:

The steps to reactivate the fingerprint sensor are only working on stock based EUI ROMS!

So the so called process

Com.qualcomm.qti.fingerprint.biometrics.service

Is only available on EUI Roms!!! If you're running a Eui rom you can use the steps I have explained in a previous post.

But it seems that freezing the process isn't necessary! You delete the data and cache inside the process and reboot the phone.

Camera taking photos by hitting the fingerprint sensor should work now. If that's the case then hardware seems to be ok.

Since I'm not running a AOSP Rom right now and being able to download big files, I'm unable to test and tell you what processes you need to wipe / stop to get FP working!

If you only want to know if your FP is broken or not, you need to flash a eui rom!

I hope to be online as normal in a couple of days.

[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Doesn't matter which Eui Rom you flash. I'm personally running latest Madsurfer MadMax. But I know from a couple of guys in Germany who are running different Eui versions. The thing is that you will be able to find the relevant process inside these Roms.

I am on cuoco 020s eui? is that good, bcz not work
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Yes couco is fine! First go the settings menu and tap on fingerprint settings. First delete the fingerprints you have already added. Then go to fingerprint calibration and proceed the steps.

After that is done youneed to go App management, all Apps and search for

Com.qualcomm.qti.fingerprint.biometrics.service

Click on the button to stop the process, then delete the cache and data.

Reboot the phone and add new fingerprints. It should work like it was supposed to be.

By the way, my fingerprint scanner was instantly reacting damn slow since yesterday, and "died" today in the morning. I wasn't able to unlock the phone or even taking pictures by using the fingerprint scanner. No reaction at all.

But following the steps i explained i got it working again in a couple of minutes. ?
