I lost all access to the fingerprint sensor. I could not use it for logon . No app could see the sensor. One test app said there was no fingerprint sensor. The Settings menu didn't show the fingerprint items, although I could search for the items. When the menus were found, no fingerprint were shown as registered and I could not add any.
I checked everything and couldn't find anything. I checked that the sensor for dirt and grease.
Huawei support suggest restarting the MediaPad. I did this and everything worked again.
Did I feel embarrassed!
Moral is: if in doubt, turn it off and then on again.

Ha ha I thought you were going to need a factory reset but like I keep telling my kids the first thing to try is turn it off then back on, 90% of problems get fixed by this lol

Hi, I would know if you have this issue too.
My fingerprint sensor works well, no problem about the speed or recognition.
But, often, it just wont work, I mean there is the vibration but it wont unlock the phone, at the bottom there is: can not use the fingerprint (I don't know in english it's in french).
I have to unlock with my code or layout. I lock again and now it works!
It works for a moment, and maybe one hour later it doesn't work again I have to unlock manually to make it work again.
Try removing and re-adding your fingerprint, make sure you scan all parts of your finger.
It is not recognising your finger as often as it should.
I have a same problem. If I turn off/restart my phone the fingerprint stop working. I must re-adding or again restart the phone to start work again. But if working, he work good until next restart. Sometimes after turn off/restart he continues to work. I think it has its own opinion when to work and when not
When I say there is an issue, it's not about the recognition.
When it doesn't, the screen don't turn on and double vibration, it's ok.
But sometimes, the screen turn on, and just say that is not possible to use fingerprint (with one vibration)
I just deleted and set again my fingerprint, and the problem is still here.
So it recognize my fingerprint (screen on and one vibration) but doesn't want to unlock, just say it's not possible to use fingerprint..
This happens to me only first time after reboot.
I think that's a security, and a will from LG. So it's not a bug, it's a feature

yes I think that happen when the state change, like wifi, BT or other.
But it's annoying when it happens 20 times per day.
I hope I'll be able to change that with root..

As others have said. I think it's a security feature that makes you use the lock code after a reboot. My G5 does the same things as well as my iPhone 5S.
As for the fingerprint scanner misfiring. I noticed that while I'm using the always on display. When I first take the phone out of my pocket. It takes a second for the always on display to pop up. It seems like the fingerprint won't read my print until that display pops on.
You're issue sounds a little different. I'd just figure I'd mention some of my findings.
I just want to remember that my issue is not about a reset. But all day long.
So at this moment I'm the only one who have this issue.
(I also have the 10c update and issue still here)
Thanks for your replys anyway.
I get it about 2 or 3 times a week & like you, not after a reboot. It works again after pin entry.
Strange but infrequent enough not to bother me.

Hi,
I have problem with fingerprint reader on my elephone p9000. I am using latest softer version and i have this problem from the begining.
So when i try to add new fingerprint it recognize my finger every fifth time, and after i set my fingerprint and lock phone it recognize and unlock phone first few time, and after that i seems like he forget fingerprint and i cannot use it.
Is this system or hardware problem?
After update i factory reset my phone but this does not help.
I find youtube video with the same problem
If you have any sugestion please.
I have the same problem too. I think you need to press the finger well for getting a good result.
I hope that this problem have a solution.

I had loads of problems with the fingerprint sensor.. I was scanning itself (no finger on the sensor, vibrates and returns "too many attempts), working only when the screen is on, not working at all, working 1/10 times I tried, etc...
My problems were all software related (some were registering technique related). It's really not possible that two phones that you have ordered had the same problem.
I have managed to fix mine by combining Resurrection Remix and DarkSense Kernel 1.2.0, now it works 100% of the time. (1.1.0 rendered the fingerprint sensor useless). XPosed and ROM Toolbox seemed to break the fingerprint sensor as well.
I know it might sound silly, but try a different fingerprint registering technique. What I do is I lightly touch the sensor with the centre of my fingertip for the first time, lift the finger up, rotate it by ~5 degrees and lightly touch it again. Do that until most of the finger tip is registered. I'm only saying this because I've seen people touching and "smearing" the fingerprint sensor, expecting it to work. Imagine it's a camera, give it pictures of your fingerprint.
I don't know if this is useful, but after a few months of trial-and-error I've managed to find what was wrong with mine.
I just installed the AEROM V5 and now it works about 90% of the time, which is more than my Nexus 5X did.
I bought an S9+ on launch day long story short it lasted 2 weeks before it would just shut down itself anytime you put it to sleep (screen off). I figured out after doing some tests and research that it would only do it when the fingerprint scanner was turned on. I sent it to Samsung which if anyone has had the pleasure of dealing with their customer service knows it's a nightmare to say the least. At least 2 week turnaround time but in the end they did come through and send me a brand new in box s9+.
Fast forward about a month later the new one is doing the EXACT same thing. If I turn the fingerprint scanner off and just use facial unlock it works fine. I really don't want to go through their customer service again and be without a phone for 2 weeks. I think this very well could be a software issue though factory reset does not solve the issue neither does erasing fingerprint and re entering them.
Has anyone else experienced this? I saw searching google that it is actually an issue others have had and like me, their replacements have all done the same thing. I am yet to find a thread with a solution though. What do you guys think? I'm actually wondering if perhaps rooting it and putting a custom rom on it would help.
Honestly, I have not heard of this before. After you try with fingerprint can you turn the device on at all?
Do you have any apps that may in the background that captures button inputs or fingerprint apps that capture slide movements or anything?

Nope it seems to go off within seconds with the fingerprint scanner enabled. Even if I try to wake it up with the power button it seems to be dead. I've had the phone for about a month now and haven't recently added any new apps. I don't believe I have any apps that would be capturing anything. Is there any app I could use to check and see if perhaps I have something app related thats causing this?
I do believe it's gotta be software related.
You can type *#0*# in the dialer, then go to sensor and scroll down to find fingerprint test
Hi,
I've read this thread and disabled battery optimisation for "com.samsung.android.biometrics.app.setting"* on my Note 10+ and Tab S6 (Wifi).
On both devices the fingerprint scanner is faster :good:
... and it seems to fix recurrent unlock problems with my Tab S6 too
* on some devices it's named "com.samsung.android.biometric"
Important:
it's not known yet if this might have any negative side effects (as battery drain or burning out the fingerprint sensor).
I also did it. But it doesn't make the fingerprint scanner faultless...
Hi, am I the only one having a problem with the fingerprint reader after upgrading to Android 10? ?
I have probably tried everything. Factory reset and clear cache partiotion do not help. The problem returns randomly. The reader stops working, and when I try to get to the settings I have the message: "Finger print sensor calibration needed " or "finger print sensor doesn't respond, try to reboot your device . If the problem persists, contact support "
I checked everywhere and there is no such thing as calibrating the fingerprint reader. Technical support also couldn't help me with the problem, they only recommended to send the tablet for service. ?
The problem has never appeared before the update so I bet that the problem is new software.
Any advice what else I could try?
The reader, when it starts to work, works much better than before the update, unfortunately more and more often it does not work at all.
The strangest thing is that sometimes it starts working after a regular restart. I have no idea what to think about it.
Something similar... It sometimes works like a charm. It sometimes stops working, but no message and no way to use it in order to activate the tab. In that case I have to use an alternative method to. I suppose a fix could be released after this update to Android 10...
solved
Hi there,
I've solved this issue. I have tab s6 4-5 month and I couldn't even register the fingerprint. today I tried again and I found out that you have to touch the scanner very gently, do not press firmly. so I could register 3 fingerprints and it is working. even with unlocking if you press harder it won't work you have to touch slightly and it is working. still it is not reliable as other scanners but it works. i'm providing the video, you can see when I touch gently it is working, but If I press harder it won't register.

i have m2001j2g on MIUI 13.0.7 version stock rom, no root. Since i bought the phone 2 years ago i have been having problems with calls. When i put the phone on my ear, the screen goes off as expected but after a while it opens again and my face touches the screen. mostly closing my microphone, and doing other stuff as my face keep touching the unlocked screen. i tried locking my screen before a phone call and tried proximity sensor reset APK. none of them worked. i really like the specs but this problem annoys me. is there any solution?

If it's not hardware problem
You can try calibration/re calibration
Goto my device>all specs>click on kernel version multiple times, it will open CIT menu
And find your desired option.
Just install "Call Proximity Sensor Fix" from playstore.
none of the recommendations worked. only proximity sensor fix app's proximity overrider works but it creates a constant notification. i use blockada for adblocking, it also has a constant notification. they keep changing places, it is annoying
edit: ok, i just unclicked show notifications for both app's, locked them on running applications, remove all restrictions: they are both working now without any notification. call proximity sensor fix it's overrider works dine, thanks all
