Sorry if this is a dumb question but how would I go about finding the goodix folder? I'm using a root browser and can't seem to find it.
Thanks! this worked for me. I debloated my phone via MagiskManager debloating and it screwed my FP. But also my 'peek display'. screen doesn't go on when approaching with my hand, i thought this is arranged through the proximity sensor. but i read that it the device sends supersonic waves to detect. Found the issue, motorola widgets was gone on my device.
Mine started working again after the update to android 11
Thanks, worked fantastically.

How To Setup Your Fingerprint For Better Recognition On Your Nexus
1) Settings > Security > Nexus Imprint > Delete every fingerprint that you have registered
2) Now, put your phone in your pocket, or in your purse, or wherever you normally keep it. Pick it up and go to unlock it with your finger. Pay attention to how you are holding the phone in your hand, and keep your finger pressed solidly on the scanner. Now, go ahead and add a new finger this way.
3) Once it has scanned your finger initially, move your finger around, attempting to ‘scan’ every part of your finger that you naturally reach while holding your phone in your hand the way your normally do.
4) Now, add a 2nd finger, and do the same thing with your other hand.
5) While at the screen that shows you your registered fingers, go ahead and put the phone in both hands and test it out. keep trying to press it; it will buzz and show you that it worked, or it will double-buzz if it didn’t. If you are getting a lot of double-buzzes, delete the finger that isn’t working, and redo steps 2&3.
---The key here is that when you are registering your fingerprints, THAT YOU HOLD THE PHONE IN YOUR HAND LIKE YOU WILL HOLD IN WHEN YOU ARE USING IT / UNLOCKING IT.---
If you've got other suggestions, please add them below, and I will incorporate them into the OP!
Since the iPhone 5s, I've always registered each fingerprint I'm going to be using at least twice. Seems to decrease the number of failed scans.

So I configured the fingerprint sensor to unlock using my left fourth finger and been using it during the now couple of weeks I have the 8X, until I realized this morning that any of my fingers was unlocking the device :crying:
Have you guys experienced the same problem? I would like to figure out if either it is my device which has an issue, or if it is the an overall problem shared by all.
Thanks in advance
did u try to remove all of the fingerprints ID and start setting em' up again?
mine is working fine i have left and right index finger configured. like hazem said try to remove all fingerprints and re configure
Thank you for your posts (the 2 of you) you were right, reconfigured from scratch and now it works perfectly fine.
I feel like it is faster than face recognition.

go to device Settings >> Fingerprint ID >> Fingerprint management >> you have to enter lock screen password >> New fingerprint, enroll your dry finger properly to keep your device secure with your finger.
If the issue still persists please reset your device with proper data backup by following the below mentioned steps:
* Switch OFF your device
* Press (Power OFF + Volume Up) buttons to enter into recovery mode
* Select Factory Data Reset option (You can scroll up and option in options via volume up and volume down buttons respectively and select an option via Power OFF button)
* Select “yes” to proceed further
I have a Mi A3 and think it's great, but there is one issue I'm facing.. the fingerprint sensor is always active and when the phone is in my pocket and touches my leg, it wakes the screen after X failed attempts.
Multiple times I've pulled out my phone to find my leg has been typing numbers into the emergency dialler..
Is there any way (prefer no root - but so be it if needed..) to use the proximity sensor to kill the FP sensor? That way when it's covered in my pocket the FP sensor would be disabled and stop waking the phone all the time.
And before anyone says just put in your pocket with the screen out.. well that's just asking to get it smashed ?
Try disabling "show fingeprint icon when screen is off" feature.
Tried that one already. Unfortunately the sensor is still alive so if something touches it the phone attempts to unlock.
After a couple of attempts it seems to turn on and show buttons for emergency dialler / pin unlock.
Not sure if this would be usable on A3, but you could try this approach:
https://android.stackexchange.com/questions/153948/completely-disable-the-fingerprint-sensor
Edit: just tried it on my A1. I can disable the FP sensor with:
Code:
echo soc:fpc1020 > /sys/bus/platform/drivers/fpc1020/unbind
BUT, can't get it back yet (only with reboot): this should be the correct command, but it doesn't do anything
Code:
echo soc:fpc1020 > /sys/bus/platform/drivers/fpc1020/bind
Custom ROMs have something like pocket mode that detects and prevents it don't they? I wish something like that would be available for stock as well. Wouldn't mind root.
I have the same problems with scanner acting in a pocket. Looks like I have to disable scanner for now. This can be done by removing recorded fingerprints from settings.
As a workaround for emergency dialing, you can use WaveUp app and set it to lock with proximity sensor. It probably won't prevent fingerprint readings, but at least the display will turn off in your pocket. Works best with root, I'm using it on Mi A1. "Turn display on when removing from pocket" feature is highly addictive. I use HW power button mainly for taking screenshots now..
Edit: Tasker with states "proximity sensor and orientation - phone upside down" and task "display - turn off" can do the same if you want to keep it simple.
Edit 2: Nicer Tasker profile, turns screen off only when the screen is locked (prevents accidental locks while using the phone):
Profile 1 - state "proximity sensor" + state variable value "%SCREEN_LOCKED ~ true", task "display - turn off"
Profile 2 - event "display unlocked", task "variable set, %SCREEN_LOCKED to false"
Profile 3 - event "display off", task "variable set, %SCREEN_LOCKED to true"
Turn display on&off with power button and you are good to go.
Thanks will give the commands a go when I get chance and see if it works on the A3.
put you phone opposite side .... screen upwards in pocket.
hi this feature works on my device when i turn off the proximity sensor the fingerprint icon does not show up on the screen
I have this problem too with Android 11.
I wanted to try the method with fpc1020 driver. The driver is here, but what is weird, that in /sys/bus/platform/devices is not such device attached :/
The easily way to do this is root the phone. After this you can disable all useless features

I have rooted phone but you probably doesn't understand the problem.
I don't want to completely disable fingerprint, I just want the FP to be disabled by proximity sensor, because it's bul*** to have enabled FP in pocket...

There"s a quick setting to add by developer settings that disable all sensors. Have you tryed? Maybe it work
I am running Blastagator TWRP 3.3.0-0 on an LG G2 with a screen hardware problem. The screen is no longer touch sensitive in the center of the lower part of the screen. Updates to Lineage on this device do not automatically install Magisk, so it needs to be installed manually through TWRP each time I update Lineage. The problem is that installing any zip file through TWRP requires confirmation by moving the slider across the screen, through the dead spot. When I try to do that, the slider drops back as if I lifted my finger off the screen. The same thing happens if I let the screen time out - I can't get past the lock screen without the slider, so I have to crash TWRP and reboot.
Is there an alternative to sliding across the bottom of the screen? I can recompile TWRP if there's a flag in the source code. I've tried sideloading Magisk, but I can't do it because I have to swipe across the bottom of the screen to start sideload mode. If I try it through the ADB command line on a connected LInux system, I get "sideload connection failed", presumably because I haven't put the phone in sideload mode. All roads lead through that sliding bar.
It would be frustrating to have to trash the phone just because of a single bad spot on the sensor. Once in a blue moon the bar slides and I can get Magisk to install, but it's frustrating to keep trying for five or ten minutes hoping I get that one shot.

I believe you can disable the lock screen in the options totally (the slider thing). Not sure though but yes, it's a crap design. Hope someone is able to help

Wow. Does it work? I didn't even knew it did lol. Thanks for the tip. Hope OP sees your post and gives it a try
Brilliant! That worked. It appears the mouse has to be plugged in at boot time, but if it is, the arrow appears and the mouse and slider are fully functional in both system and recovery.
By the way, I get around the dead spot on the keyboard when booted into the system by using one of the many Set Orientation apps that allow me to turn the screen upside down. I haven't found an app yet that needs touch sensitivity at the top and bottom of the screen at the same time. Well, games, but I don't play games on an LG G2
I wonder if a Y cable will work on the USB port, so I can plug in a thumb drive for storage and still use a mouse to move the slider to start the backup?
BTW, I checked the TWRP settings screen. There is no setting that affects the slider.
Thank you, eyobaaa.
Glad to hear that the Y cable things i didn't test it why don't you give a try..

I'll have to buy one to do that. Probably next week.
I can't set up the fingerprint, everything else works fine, the imei checks out, flashed stock rom but when i tried setting up the fingerprint the entire display turned off, only when i press the return button (which doesnt even show up on the display) then it'll return to normal. Tried pressing my finger on it but it only vibrate twice, i checked with the smart doctor app and the fingerprint sensors says goodfi

Try this!Run the test,and see if it corrects the fingerprint issue!
1: Clear the lock screen and restart the phone
2: Enter the engineering mode after booting (#*462633*#500#) or (*#546368#*500#)
3: Select the device test
4: Select SAAT
5: Select the service menu-manual test
6: Choose optical fingerprint test
7:Hit start,and see if that corrects it!
i did tried that which ended up the same as before, i did link some attachments in the replies to show the problem better
