Fingerprint problem using with apps - Huawei Mate 20 Pro Questions & Answers

I have several apps that can authenticate with fingerprint. But what I'm having happen is that when I launch the app, the fingerprint screen pops up and immediately it goes away and to the app screen. Depending on the app it either just requires a password or has a message if "You have used all password attempts".
Anyone else seeing this, and have a solution?

The problem is likely in the apps.
I use 3 bank apps that require fingerprint authentication for confirming every operation and they are working flawlessly.

I have one app which sometimes does not prompt the emui black overlay screen for fingerprint.
Going to 'recent apps' and choosing said app again, show finally the fingerprint screen overlay.
I choosed to disable fingerprints checks for this app.

They all work great on my Note 9. Do, I don't think it's specifically the apps unless it's a compatibility issue between then and Huawei phone.

Probably some apps need to be updated for Android 9 and likely for managing an on-screen fingerprint scanner, which is more difficult to deal with than a physical one due to the overlay operation, particularly if an app doesn't strictly implement the Google Android fingerprint specific API.

I got to thinking about that, and I bet you are right.
I'm surprised I let myself purchase this phone with the in-screen FP reader. I never liked the idea. It's so convenient on the back...holding the phone, the finger lands there. I never understood what the big deal was about having it on the screen.
Add this to that equation...makes it frustrating.
Thanks for the input. I was wondering if anyone else was having the problem...interestingly not seeing that in the replies.

Hang on. I own Mate 20 Pro since November and I have never had this problem until more or less a week ago. I am using many apps where I authenticate with a fingerprint and they have been all working absolutelty fine. It just got broken a week or two ago. I don't believe it is app related since many apps suddenly got affected. It looks like a firmware bug to me, possibly after the latest update?

Yeah it after first emui 9.1 update.
Only Google Play/ pay is acting up like that.
Sure there is an update coming with July patch
Also fixes sudden shutdown.

I have some Apps where the fingerprint button is not visible after the update, but the function is still working. You just have to know the position.

apps to locate stolen devices

i am currently searching some apps to help you locate your phone.
both ios and blackberry have free apps that lets you ring, wipe, send message, lock and locate via gps your phone. even blackberry has the added feature that will backup your data, and can even be configured to do it automatically or just over wifi.
what options do we have on android? for what i have searched there is "where's my droid" that has some basic features with sms but due to a recent android restriction it cannot turn on gps
Lookout Mobile Security
Motoblur actually has a device locator and remote wipe built in.
https://portal-blur.svcmot.com/blur-web-portal/
My only issue with that is if someone gets ahold of your phone they can wipe it really fast and than your sol. With lookout you can at least lock the phone so no one can use it

not if you already have a lock on your phone via fingerprint scanner or pin
Wavesecure also works good.

Prey works quite well.
Prey..
but a very lightweight one..
TheftAlarm... is a pretty small one lol. not a lot of functions but.. it checks on anyone who puts a random sim on your phone.
Someone else mention Motoblur and I have to say this is the best option.
Combined with any type of screen lock, fingerprint scanner or the standard locks, you would be safe and sound. If someone tries and switches out the sim card, the phone goes into lockdown until your motoblur account name and password are entered.
You can track the phone and remote wipe it all from their website similar to apple's mobile me.
Prey is a good option, but not as reliable on the tracking portion I think. It does have however a nice lockdown feature.
I've always used MobileDefense but I noticed no one here even mentioned that so perhaps it's really not all that great?
MotoBLUR's tracking with Autowipe (free) from the Market is winning in my book.
Motoblur couldn't locate my phone. Just kept searching for a while and then it just stopped.
Is gps on?
Sent from my MB860 using XDA App
this is a cool feature.
motoblur would be perfect if it could turn on gps. Pretty sure lookout has the ability to turn on gps for you. Also has a pretty neat tool called plan b that can install and report location after your device goes missing.
As of right now I have my gps on at all times. If I eventually turn it off I will switch from motoblur to lookout.

You could also use androids web store to push programs, but not sure if it would auto work or not
Sent from my MB860 using XDA App
it will def. work with the "plan b" application because it is designed to be pushed out through the web store after the fact. It installs remotely and even enables gps for you. Within 10 minutes it emails your google address with the location of the phone. If it doesn't work after ten minutes you can send a text to your phone with the word "locate" to force it.
haven't tried it but I like the idea

Unwanted Vchat App icon appeared on home screen, but not in application manager

I just noticed that an application was added to my home screen called Vchat. I didn't install this app. I checked the application manager and my account in the play store and this app doesn't appear in either. I'm not really sure what this is and what the best way to remove it is. I haven't clicked on it. I also notice random ads popping up after the unlocking the screen, though they are very sporadic.
I'm on a LG G5, the verizon version, running android 7.0.
Girlfriend also has this on her Samsung Galaxy A5, couldn't identify an app in app list which matched. Removed from home screen and hoped it was simply a sketchy weblink. Will follow post to ensure phone is secure or if an app needs removing. Seems to have appeared in last 24 hours.
I tried running avast and malwarebytes on my phone. Neither of those detected anything.
Came up 3/30
I Googled this yesterday, glad I did again today to find this forum. I bought this phone March 22nd and I am noticing my lock screen button stopped working around the same time the app appeared. This phone is brand new from amazon and I am about to return it, but something tells me this issue is software related as the button was working fine on 3/29 and now it clicks and is responsive to the touch, but it will only "sometimes" lock the screen. Right now it is fully functioning, but it will start to fail if I have too many apps open, or if I am running a game. It specifically won't work while in an app, but will work when on the home screen with no apps open.
On top of all of this, my phone has been getting weird ads, but male ware detection doesn't see it, also, the phone is a lot slower now. Whatever this is, I don't want to be connected to it.
Update: the v stands for Vietnamese. The app is some Vietnamese chatting service. Googled "vchat' you guess should try it too.

I did look it up and found that. I'm just trying to figure out how it got there and how to remove it.

I got frustrated trying to figure out how to remove this app, so I decided to restore the phone to factory defaults. I've only had the phone for a month, so I didn't have much on it.

I have a Galaxy S5 Android version 6.0.1 and this URL shortcut also appeared on my homesceen. Likewise I would like to know what app / service was used to create this advertisement so I can disable / uninstall it.

Another S9+ fingerprint sensor problem (i think)

So I've just got a new S9+ (previously had a S7 edge) and it works great apart from one annoying "bug" (which may not be the phones fault)
The fingerprint reader isn't working with 3rd party apps (banking app, PayPal etc)
It DOES work fine (and fast) to unlock the phone so I know the sensor isn't faulty but when I try to log in to the PayPal app with my fingerprint it just instantly switches to password log in - no error message... My banking app (Natwest - a UK bank) does give an error message "Sorry fingerprint login has failed due to a system error" and I then have to use a passcode to login.
It's not the end of the world but annoying as the S7 work flawlessly with fingerprint login
Things I've tried:
1. Checked for updates (all up to date)
2. Turned off smart gestures
3. Removed my fingerprints and re-added them.
4. Done a diagnostic of the sensor - shows working fine
SO... maybe it's the apps that are at fault? Does anyone know if the API's have changed on the S9 and S9+ for security that would mean the apps won't authenticate until they are updated? Or is anyone else using PayPal with the fingerprint login and it works ok?
Yes PayPal working fine with fingerprint.
Maybe you have disabled something that is needed for it to work or not allowed some permissions for the PayPal app
Thanks for the reply - I can't think of anything I have disabled and the apps asked if I wanted to use fingerprint login and I accepted - no permissions settings I can find for them regarding fingerprints?
I'll try and take this up with Samsung support and if I get a solution I'll post back
Thanks again...

I also have this problem. However, it worked fine for me for a while and stopped working in the last couple of weeks. I even uninstalled magisk and unrooted but still no luck. (it worked fine even with magisk). I also tried the steps you mentioned but still no luck.
Did you find any solution to the problem?
For my note 9 it worked
Hi all,
I had the same problem on my Samsung Note 9.
- Banking app
- PayPal
A simple trick sorted out the problem for me so you might want to try it.
Login to the app and then disable fingerprint loging. Log out and then log back in with password/PIN. Then enabling the fingerprint login and then logout again.
Wolah! Logging in with fingerprint should work now.
For me it was the sensor's paint peeling off. Maybe the paint generally causes problems. Clear the paint carefully with 400+ grit sandpaper and leave the sensor black.

Cannot use fingerprint to authenticate.

Hi All,
Is anyone else having issues while trying to authenticate apps (or open apps) using fingerprint on the device? (Say Google Pay, I cannot log in to the app with fingerprint, phone asks for Pattern/Password).
If this is not an issue, please let me know how to enable it. I checked in settings, looks good.
Please note that I am able to unlock the device using FP
Help is appreciated!

I don't think there any option to enable it. It's system wide support that's missing from xiaomi on POCO. it was there on Mi A2 (obviously, being Android one).SO i think we need to bring this one to POCO Team's attention. Send Bug report for same & Tag them on twitter if you are there.

Yup, I dont think it works on miui. I am not able to authenticate any of my banking apps via fingerprint.
I guess its depends upon the app developer. There is no fingerprint authentication for Google Pay/ Tez but I can enjoy this feature with ICICI banking app.

I checked. I can use it on my bank accounts, app lock, and third party app loks as well.
The thing with Tez it that it relies on Android's native screenlo k or Google Pin, now the app is probably not able to leverage the screen lock fully (the Fingerprint), which should be brought to Xiaomi's notice. I'll be writing this on the Xiaomi Forum now.

I can't get it to work with the same app. It just says fingerprint authentication failed multiple times before I even place my finger and then it forces me back to using my pin.
Not sure with Google Pay/Tez since we don't have that in my country, but my banking apps work fine with fingerprint. Even PayPal works. I suggest updating the FIDO and IFAA certificates. If it doesn't then best bet is to truly contact Xiaomi or post in forums (though contacting them directly may be best to get any answers straight from the horses mouth)
It worked fine for me but since the last update (10.1.3) it has become unreliable - 50/50 chance of it working. Unlock device works 100% of the time. Tried recreating all the fingerprints and same issue.
I've the same problem.
All apps i decided to secure with fingerprint, can't be unlocked with fingerprint.
Only the option of PIN is available, but don't work either.
It's the same problem as drawkcaB has told...
Did everyone solve the problem?

I had the problem, before the 10.x update all apps were working and after I had an error. I solved it by reinstalling the concerned apps

Thanks for your quick reply!
The problem is that it mostly affects the pre-installed apps from xiaomi.
Unfortunately, you can not uninstall these.
Presumably a reset to factory settings will be unavoidable?

For me it was only 3rd party apps, bus you can try wiping the app data/cache individually to see if it works?

Fingerprint icon is not showing on lockscreen
I have seen fingerprint icon on lockscreen of stock android and OxygenOS. Also in Gpay if enable unlock using lockscreen fingerprint icon is showing on Gpay authentication window of both the phone. Since fingerprint icon is missing in lockscreen of poco make it depreciated to gpay authentication using fingerprint.
Yes, I am also facing same problem. Could you resolve it?

Barclays Bank App contactless payments.

After the recent update to the Barclays app it doesn't seem to stay open in the background so you can't use contactless unless you log into the app everytime. Am I missing a setting in the phone somewhere?

If you go into settings/battery/app launch you can remove that app from battery optimization and allow it to stay open in the background. That might work--I'm not familiar with the Barclays app.
Thanks for your reply. Unfortunately that's how I got it to work originally before they updated the app. That doesn't seem to work now though.
I have the same problem and the latest app version. However jhs39 is correct for the fix. Go into settings>Battery>App Launch select the Barclays App so that it is "Managed Manually", you can leave all three options enabled. You will then need to login to the app once more. You should then be working. I think the issue is that the app want's to have an active process running but the battery manger sweeps it up as it is not recognised and using power!
The really bad thing about this app is that if you reboot your device (or it loses power - battery drain) you will have to remember to re-login each time..... Google Pay and Amex Pay do not have this problem - poor app.

Some people may call that a useful security feature that is missing from Google Play & mex Pay
Working fine now. I had changed some other settings to allow it to run but not these ones. Thank you

You have to jump through enough security hoops to get the card into the NFC chip but I'm all up for security. My point is that this is a poor app because it relies on an unprotected process and when it does fail it comes up with ERROR CM057 which is not really helpful. Furthermore no-one in Barclays can tell you what it means. A better response would be "Please login to complete the transaction" or your "Login Details have expired". So yes this is a poorly written app that Google and Amex do not suffer from.
After discussing the issue with them on Google Play and being asked to be some sort of QA Tester for their broken app that they use in lieu of better contactless options I just gave up and transferred my account to another bank. I can now use Google Pay, problem solved.
How does contactless payments work through the phone? On my iPhone, I would double press the home button to get my list of cards up. I have a Barclays and Tesco card - both of which, do not support Google Pay. 'Doh!!
Do you remember which settings you tweaked to get it to work?
I tried the battery management settings and it is unchecked so it is managed manually with all 3 other options that pop up left switched on but I'm still having the same problem, ever since I had my P20 Pro in fact. When I got my 2nd Mate 20 Pro (1st was replaced for the gluegate issue), it worked once and one other time when I tried switching NFC off and back on but apart from that it hasn't worked since.
I wish Barclays would just ditch this "feature" and allow Google Pay to add Barclay's cards. It's so frustrating standing at the check out trying to get it to work, opening the app, logging in so your balance is there for everyone to see, exiting the app etc. etc. and then it still doesn't work for me and I have to end up going through my wallet to find my card anyway. It won't even work for me on the pay screen with the 30 second countdown!
