Mi Mix 2S fingerprint problem - Xiaomi Mi Mix 2S Questions & Answers

Hi guys,
It seems i have an issue with my fingerprint sensor...
It began with a failure of the sensor, it stopped read my fingerprint.
I erased the fingerprint, tried to add a new one, with a new code, with no success.
Simply, when i put my finger on the sensor, nothing happens...
Phone is 4 months old, still on warranty...
Installed a new rom from the scratch with miflash, everything stays the same, sensor not detecting anything.
Anyone with the same problem?Any workaround, or how can i perform a test??
Any suggestions or ideas are welcome.

Press several times Kernel source on your settings-about phone , option 31 test fingerprint sensor ... Does it work ?
If not , did your phone fell on the ground or something ? It sounds like its hardware problem maybe it have to be replaced

Thanks for the reply.
Nothing happens...after pressing "enrol" and then touch on the sensor, do nothing...
It's strange, because i never dropped the phone...it has a glass protection and the original case...
The fingerprint sensor just suddenly stopped worked....

Does the phone have warranty ? Its a hardware problem

[Q] Fingerprint sensor

I have my device unlocked, not coded - european version. It was all good no problems with anything.
Just last night i went to sleep and when I woke up in the morning I noticed this error on my S6:
"An error has occurred with the fingerprint sensor. if this message appears repeatedly, restart your device."
Clearing cache did not help. Nor dit the factory reset...
Tried running fingerprint test by typing *#0*# on the phone app but it stopped with no result so I guess there must be something wrong with the fingerpring scanner.
Honestly I am very dissapointed and must admit that i would not expect one of the major funcionalities to stop working after less than 48 hours from buying.
Anyone else having this?

I've just started getting this too. Mine is 11 days old. Did you figure out if it is a hardware or software problem?

Kind of.
Apparently some of the SGS6 units are faulty and have loose home button or not well clipped or anyhow you describe it.
So its a hardware problem. They should repair it by replacing the front screen, glass and home button or just give you another phone.
Give it to the warranty.
Today I am very dissapointed in SGS6, would not buy it another time. It is not that spectacular at all.
Better wait for Note 5 or choose another brand.

Thanks for the info. Must say, I share your view. The phone looks nice but thats about the best thing I can say about it at the minute!
I'll speak to Samsung in the morning and see what they say.
Sometimes it happens to me too but its very rare and I just have to unlock the phone via password and then the sensor restarts working. I dont think (hope) its a hardware issue.
Well mine is not working for a month now. Not a single time. So its hardware believe me.
I will give it to warranty when possible.
Yours apparently is software issue, or even hardware but not that serious.
I spoke with samsung and was told it is a known issue that they can deal with under warranty. Fortunately mine presented quick enough that I'm getting a replacement from EE.
I had the same issue of sporadically not working. Replaced the phone (warranty). Have the exact same issue on the new phone. Guess I'll exchange yet again. Very frustrating.

Fingerprint Scanner Does Not Work [Clean&Dry Msg]

Ever since i got my T Mobile Galaxy S6 Delivered a couple of days ago, the finger print scanner does not work.
It keep displaying the message :
"Make sure that the home key is clean and dry, then try again"
Here is a video of the problem: https://vid.me/aHjp
I bought the phone on Swappa, and the seller claims it never got wet.
I've tried searching for similar issues but have no found anything like it... any thoughts?
I just did a hard reset and still the same issue.
Anyone with any insight please?
Make sure there isn't a protective strip on the button. Peel it off. Had one like that, felt the fool...
It's probably on the way to not working. Mine said that a few times and now always gives me the fingerprint sensor error message.
Hard reset hasn't fixed it.
It's a common issue. Happened to me as well, now it's not working

So what is Samsung doing about it? Can we all submit complaints to them in a common place so they do something.
Should I send it in as a warranty repair?

I would. I switched to an iphone 6s+ and i'm sending my S6 to Samsung for work. The fingerprint sensor stopped working and it has a serious hardware issue with the wifi. I only hope they don't blame their **** product's problems on the crack in the back glass.
So my fingerprint scanner started working ...out of no where.
I ran the test under #*0#*
And it says failed... but it works. For now
Weird
it happened again
tip : when I put my finger on home screen , the message vanishes as it read my fingerprint
it's a software issue after updating my fw
now what?
Samsung galaxy note 5 fingerprint scanner not working after factory reset
I also got the same issue. Everything was working fine and i factory reset the phone to clear storage space. After the reset when i tried to set my fingerprint the scanner stopped working and started giving the same dry and clean message. I have realized that the phone doesn't even tries to read the fingerprint and anyways gives the clean and dry message even if i don't touch my finger on the sensor. I think that Samsung is doing this on purpose. I think that we all should get together in this forum and we should try to contact Samsung about this issue. The have to do something about. Thanks

Fingerprint sensor bricked after mainboard change

Hi guys.
I have an S7 border and my mainboard phone is dead. I bought another mainboard from a phone with the broken screen. Replaces the mainboard and everything worked perfectly except the fingerprint sensor. Does the firmware kernel fingerprint sensor driver on the new motherboard is incompatible with my fingerprint sensor hardware? I have the sensor that came in the phone that I bought, but it is of another color and I would have to remove the display to replace the sensor, with a high risk of breaking the screen. Do you think it's possible to be kernel incompatibility? Any guidance? The error is: "An error has occurred with the Fingerprint Sensor. If this message appears repeatedly, restart your device." I already removed the firmware for andoid stock 7 and 8 but did not solve this problem.
Please, somebody knows something about this?
Anybody can help me?

Did you make sure everything is plugged in properly? You could try plugging in the home button /fingerprint sensor from the phone you bought and just leave it hanging out for testing purposes just to make sure it's the actual sensor or just something not plugged in properly.

Fingerprint sensor not working after screen replacement

I just had my op7's screen replaced. The fingerprint scanner is registering the fingerprints but it won't unlock the phone. I have tried clearing the cache and adding multiple fingerprints for same finger.

Claim warranty, if it's not working, they need to fix it.

Same problem....
Did you solve it?
Old fp sensor should be transfered from old frame to new one. If repair was done by 1+ - claim for warranty repair.

already moved to the new frame, it's strange that it doesn't work
Hi, Did you solve the issue? I have the same issue now..
Got the screen replacement today and on the way back i realised the fp sensor is not working...
What did you do?
Please reply ASAP.
Thanks
Is it's work.you have to allow some time to calibrate again. keep trying to put your fingerprint until it goes and then leave it,with time improves the unlock time but it will never be like before.
by chance do you also have problems with the light sensor?
Can I ask why did you people get the screen replaced? Iam using a OnePlus 7 too.

Because we broke it any way.
For all: Facing same problem on my Oneplus 7T. (Oneplus repair center told that, they need to flash the software and it will fix the problem.)

Lost fingerprint in settings

Hi this morning suddenly I can't unlock my phone using fingerprint and there is no fingerprint option in settings. Has anyone else experienced this? Should I do a factory reset?
EDIT
I did a factory restart and it is official the fingerprint is gone...
Mine just disappeared. It has happened before and returned on its own, but not this time. I am c567 with 9.1.0.252 flashed. Maybe flashing a different version will get it working again
Maybe a hardware issue, loose fingerprint connector or something.
Then EMUI disables Fingerprint option if sensor is not found
Try googling for Huawei secret dial codes to find a hardware test for Fingerprint (?)
Mine must have been the connector because I put the phone face down on a table and put most of my weight on the back. After a restart the fingerprint came back to life. Obviously you risk breaking it but it worked for me.
