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

To re-calibrate proximity sensor in LG G4.
This issue can be solved by re-calibration proximity sensor, you still can use screen protector with sensor covered up.
Mine is H815.
Follow steps below to re-calibrate proximity sensor(must with the glass protector is installed and which is sensor covered up)
1. TYPE *#546368#*815# in phone dialer. Hidden Menu screen will show up. <- G5 is *#546368#*860#
2. Select "Device Test"->"MT", it will show "system will be restarted", then choose OK. <- i can't find "MT"
3. After reboot, GENESIS MiniOS 3.1 screen will show up, press "individual item+power" while power button is pressed.
4. Next, find "sensor test", enter it(do not block the proximity sensor), the proximity sensor will be automatically calibrated. Then block proximity sensor two times to exit.
5. Find "Back to the MainList", enter.
6. Press "Normal boot+power" while power butten is pressed to reboot system, done.
Now the problem should be solved.
In the service menu:
Device -> SAAT -> Service Menu Auto Test
The calibration can be performed from there.
Choosing Service Menu Manual Test allows for manual testing of other components.
Auto Detecting Item is the proximity sensor

thanks u
*#546368#*860#
Device test->SAAT->Service Menu - Manual test-> key press test-> press cal start !!
it's work for me!!
thank u!
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
1. Take backup of /mnt/vendor/persist/goodix/
2. Delete goodix folder
3. Delete all saved fingerprints, if any
4. Reboot
5. Enter *#*#2486#*#* in dialer
6. Select CQA Menu Mode
7. Select Sensors -> After-Sales -> Fingerprint SPMT(Dual Rubber)
8. Start Test
9. Use White Paper under your thumb for FLESH FLAT
10. Cover entire screen with dark thick paper for BLACK FLAT
11. The test should pass. Go back to Sensors
12. Select G5GoodixSelfTest
13. Put your finger on sensor and you should get success
14. Select G5SPMT Test
15. Follow steps 9 and 10. For Last test, place your thumb directly on sensor. Test will fail.
16. Select G5GoodixPerformanceTest
17. Follow steps 9 and 10. For Last test, place your thumb directly on sensor. Test will fail.
18. Exit engineering mode and enroll fingerprints in maximum brightness and in high day light
17. Enroll multiple entries for same finger
18. Keep locking and unlocking the phone and after few unlocks, sensor will work as new
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.
I've been documenting my struggles with my lock screen in another thread. But I just had a major breakthrough and didn't want this to get buried.
To recap, my lockscreen has been a buggy mess from day one. The fingerprint sensor barely works, the fingerprint icon randomly disappears, and the gray border that's supposed to appear around the fingerprint icon simply doesn't show up. The lockscreen doesn't light up when I pick up the phone either (it stays dimmed). Also, wallpapers don't show up on the lock screen, and the big ugly clock sometimes disappears or moves itself to the top-left.
I've tried just about everything to fix this. As a last-ditch effort, I added a new user profile only to find that the lockscreen works perfectly well for this new profile (but still not for my main one).
Here's my main profile with the unusable lockscreen:
broken lockscreen of main profile
Watch "broken lockscreen of main profile" on Streamable.
streamable.com
And here's what it looks like when using the other profile:
working lockscreen on new profile
Watch "working lockscreen on new profile" on Streamable.

So there's clearly some obscure bug that most people aren't experiencing here. I'd love to just figure it out so I can move on.
When I didn't have the "always on display" turned on, the phone was very consistant about turning on properly when I picked it up. I ran it this way for 3-4 days without any issues.
After reading some articles on the P6, I realized that it has an AOD and that it was turned off. So I turned the AOD on while leaving all the other settings set the same. At first, the finger print icon wouldn't appear consistantly, but that is because I had adjusted the animation scale settings in the Developer settings. Changing that back to stock fixed the issue with the finger print icon not showing up.
That beings said, I have experienced the same "unresponsive" screen many times over the last couple of days that I have had the AOD turned on. The screen stays dimmed (or even turned off if I pull the phone out of my pocket) and the finger print reader is inactive (even though the icon is displayed). The screen is suppose to turn on when I lift the phone up, but it doesn't always do it. When this happens, I have to either manually turn the screen on using the power button, or double tap the screen to wake it. This is clearly a bug in the system somewhere. I probably need to report it to Google, but hopefully it is fixed soon.
After spending way too long on this, I've determined that the bug occurs consistently with these specific settings (although it may also occur for similar ones):
Lock after screen timeout: 30 minutes (or anything high enough to prevent it from locking between tests)
Power button instantly locks: disabled
Lift to check phone: disabled
Tap to check phone: disabled
Always show time and info: enabled
Replication steps:
1) Enter the above settings
2) Press the Power button to go to the lockscreen
3) Set your phone down for a couple seconds
4) Pick your phone back up and try to use the fingerprint sensor
Result: The fingerprint sensor won't work the first time.
I think all the other issues I had were actually stemming from this one issue.
