Which FP sensor do I have - FPC or Goodix?? - Xiaomi Redmi Note 3 Questions & Answers

Hello friends,
I recently bought Redmi Note 3 (kenzo) in August 2016. It is made in India.
I have confusion over which fingerprint sensor is on my device. Is it FPC or Goodix?
I am attaching some screenshots, which leads to think that my device may have FPC fingerprint sensor.
Friends, help me to identify FP sensor on my device. Thanks in advance.

I have the Redmi Note 3 (2gb/16gb) from the first flash sale in India ( I think March 10 , 2016 ) and ur touch panel , LCD and camera sensors are identical to mine . I can't for sure tell urs is goodix or fpc but I noticed that u have a different battery id . maybe that -2% bug might be there if u flash an incompatible kernel

I had flashed CM 13 build but I didn't face 2% battery bug yet
But I got FC while opening Security tab and no option to configure fingerprint also

It's confirmed now. I have FPC sensor. Also no 2% battery bug for me and both cameras work fine. :laugh::laugh::laugh: :good::good::good:

Because it is working with official CM 13 as well as custom kernels too.......
Currently custom ROMs based on official CM 13 and custom kernels for CM / AOSP not support Goodix FP.
So my device definitely have FPC fingerprint sensor

Ok,so i haven't flashed cm 13 but i previously flashed radon and blaze kernel and my FP was working,so it means i have fpc FP sensor?
Ps-i have goodix and fpc both folder in root/data/

On which ROM did you flash Radon and Blaze kernels ??
check this folder "/root/sys/class/input" There will be folders like input0...... input1 and like this.... open that folder and open "name" file in that folder wtih text viewer and check.
Also can you able to take selfies with FP scanner ??

check for other input folders too..... and you may find fpc or goodix related info in it.
Also do one thing, go to about phone..... tap 5 times on cpu..... you will get a notification of bug report creation..... complete it.....
Then a file will be created in internal storage/MIUI/bug report.zip, extract it
Open that file, there will be a text file. Open that and check for this value "androidboot.fingerprintsensor" or "androidboot.fpsensor" and check what is after "=" mark.... if it is "fpc" then you have FPC fp scanner.

Ok i found input 9 folder and in the name file it is written fpc , attached in SS
And about bug report ,there are like 4-5 text file, searched for androidboot.fingerprint and androidboot.fpsensor ,but there are not a single entry like that
One thing i like to mention i found something like this in bugreportfiles which is attached in SS too.

I also have fpc related file in input9 folder. I was on MIUI 8 v6.9.9 MM based. And your phone configuration looks same. I think in India they have sold devices with FPC, tianma panel, and samsung camera modules

Yea i saw your pics in OP,the version mentioned for sensors are same and my phone is also made in india.
Thanx for the help , detection of which FP is on phone was a confusing becuz some ppl mentioned aida64 is also giving false positive results.
Needed some strong evidence. :laugh: :good:

Yeah... many reported that.... but with aforementioned steps we can conclude which FP sensor our device may have

I've checkd it.. Input9 folder contains Name as "uinput-fpc"
That means I've FPC sensor???

In terminal emulator
Type su
Grant root access
Type cat /proc/cmdline
Find and check androidboot.fpsensor=****
Or just flash any ROM that would guaranteed break goodix for easier checking. XD
Searching for goodix on the root directory on mine yields lots of results so I first thought I have goodix. But after flashing several ROMs and not one breaking my FP, now I know I have FPC.

Incorrect G-sensor/Accelerometer Calibration

So, there's a fix on the MIUI ROMs via typing this secret code in the dialer *#*#6484#*#* (test mode)
But on ROMs like AOSP, CM, CM based ROMs doesn't have any test mode to Re-calibrate the sensors.
So is there any way to fix this highly ignored minor bug on AOSP, CM13 ROMs?

And many others are having it as well (I saw them on miui forums. However, I'm not a developer so I don't know what's the code on MIUI and what's the use if it.
But I think it could be fixed (recalibrate) via test mode which only MIUI ROMs have

I lost my hope and you should too
With low light gyro don't work correctly, in miui, CM and Lineage, since MM. The only solution is disable autobrightness and put it in normal contrast. Miui don't fix this bug.
If sensor light detect less than 10 lux generate conflict with gyro.

Unlock and flash cm13 questions.

Hey everyone,
Got permission to unlock bootloader few days back, but cant unlock due to error at 50%(account different or something like that). According to some users i should wait a few days to try it again. (Already tried i.mi.com trick with no luck)
Next, i want to flash latest snapshot of cm13 official, but apparently certain fp sensors(goodix) doesnt work there. And i saw there is Santosh unofficial cm13 build with goodix fix. So how do i found out which sensor i have? So i can flash a cm13 build which is sure to work. Also,is it true led notification has no breathing in cm13?
Thx and have a nice day....i for sure am having bad day everyday using miui..

What custom Rom or MIUI are you?
Whatever it is, please clean flash again
If problem persist, maybe your unit is faulty

Persist means "continue to exist"
If problem continue to exist, maybe its a hardware problem but try factory resetting or clean flash the ROM first. Might be the ROM badly interfering with the sensors.

Let me tell you the full story behind this phone.
I got this phone 2nd hand from my friend .
My friend locked (Parttan lock) the phone and he gave the phone to a local store to fix it .
Before that the phone was working fine with all sensor .
After fixing from a local store the problem was shown .
When I got the phone Compass Sensor was working .
But after Android N update the compass is not working too with all sensor not working.
But when I touch fingerprint sensor ,its lights up my phone (Not unlock )
Now Please Tell me how can I fix it ...
Sorry for bad English..
Try to clean flash your ROM.
Don't forget to backup all important data.

And all thinks are working
Hallo guys ..
I've mi x4 and I've the same problem that you have .
The sensor and the rotate are not working ... I don't know exactly what happened . But the both are not working anymore .. anyone has any advice for me .. and thanka
Problem happened due to MIUI 9 updatation. Just simply Go to settings - additional settings - developer Option and turn off the MIUI optimization in the last of the list. That's it.
Hi GabrielScott
I'm a new member, and scuse me if this not a local to put this question:
but following this issues (sensors of Note 4) i buy 2 covers to my Note4x, ,the 1st cover is designaded for Note4 x -Gearbest and active the sensor -Auto wake-up/sleep - the 2nd (i not pay attention on by) was indicated on gearbest with auto wake-up/sleep for Note 4, and it not activat the sensor, of my Note 4X. Why ??
The local sensor of proximity on two model of Note 4 and Note4x are in diferent zones of screen ??

[Magisk] RN3P Fingerprint shutter support for PIE roms (gcam) (Magisk Module)

Hi here is a Magisk Module I created to enable support for taking pictures with the Redmi Note 3 Pro (SD) fingerprint sensor, I have tested this with stock camera app in Havoc OS 2.3 and several GCAM camera apps, I have successfully taken pictures using the fingerprint.
so far I have only tested this using HAVOC OS 2.3 (PIE), it might or might not work on other OSes/ Android versions, I also only tested with a FPC fingerprint sensor, if you have the goodix chip I added support but cannot test so it may or may not work.
Enjoy.
Magisk 18+
V1.
Initial support.
how to use this

Install the module under Magisk Manager - reboot.
open Gcam 5.1+ , press your finger on the fingerprint sensor and it will take a picture similar to how it functioned in MIUI .
There is a bug where it doesn't work with video recording (depending on gcam)., but general picture taking should work fine.
I have only tested it on HAVOC v2.3, so it might not work on other roms.
first i flash it via recovery and not working im on havoc 2.3

I think that program says that for either sensor. (could be FPC or Goodix)
anyways you can try installing this program (you can deny the root request since its not needed for the info we need.)
https://play.google.com/store/apps/details?id=aws.apps.keyeventdisplay&hl=en_US
and see what the "scancode" returns when you press the FP sensor, it should be '96' but it might be different for your device.
nothing happen no scancode..how do i install goodix

hm it should show a scancode when you touch it, so maybe Goodix doesn't support input functions (if i recall correctly I don't think Goodix FP sensor worked for taking pictures in MIUI either).
you might still have a FPC sensor but something with the kernel might be blocking the input, I noticed you are using the ANGi kernel perhaps this is causing the issue, since the kernel controls a lot of hardware, I only tested with the stock Escrima kernel.
Hopefully some more users provide feedback if its working on their devices.
Working well on LOS Nougat. Thanks.
Tested with latest Pixel experience, no custom kernel. Sadly, not working. Keep up the good work though
