Fingerprint wake issue - Xiaomi Redmi Note 3 Questions & Answers

Hello,
3 days ago I bought this Mi Note 3 32GB, it was on display so no accounts were added or anything like that...... I got a discount just because the phone was on display and the shop sold it to me as used.....
In the shop I added my fingerprint just to test it and the phone woke up without pressing any buttons....
Now the problem is that when I got home, I performed and factory reset and after I added all my accounts and apps.
Now I can't get the Mi Note 3 to wake up with the fingerprint..... I must press the power button and then unlock it with my fingerprint or with pin.....
I'm seeing all these reviews on YouTube and all are unlocking the phone without pressing any buttons.
I've deleted and added again my fingerprint but it is still not working.
Please help.... What should I do?

Try to reflash the rom with miflash (or via edl mode). This seems like a software issue.

Is there any tutorial on how to reflash ? It's my first xiaomi device and I have experience with miflash....

1. Perhaps you should try disabling google smartlock (not sure where it is, maybe lockscreen or security or privacy, i'm not using MIUI currently). 2. Next, try to NOT use any lockscreen apps. Some lock screen apps use Secure Lock when u turn off the screen, which means, no matter what, it will need u to insert pin/pattern/password.

did you get a fix for this issue? I am also facing the same problem for the last few months.

Also have same issue o note 3 pro from gearbest

I am having the same issue on my Xiaomi note 4x, it needs two taps on the fingerprint scanner to unlock the phone, how can I unlock it with one tap

I sometimes have this issue when the phone would not unlock after placing the finger on the sensor. This is observed increasingly day after day. However, this usually tends to happen if your finger tip that you use to unlock is slightly moist. For example, if I am in an air conditioned car and then after a few minutes, try to unlock the phone, it never worked for me. The sensor tends to give up even with the slightest moisture.
I also observed that when this happens, I unlock with my password and then immediately remove the registered finger print and register a new one and then it works.
I should also mention that at times, after placing the finger tip on the sensor, the phone unlocks but after a couple of seconds (almost 3 secs).
To be very frank, I was having no issues with the MIUI version 7 (the version that I got my phone with). This and other battery drain issues never happened in that version. Was at some point thinking of rolling back to version 7.

Im having the same problem as thread strater. I have to disable my app lock feature for it to work.
If you do not want to disable app lock. You must not sleep your phone with the locked app as the active app.
For insstance, if i activated app lock on whatsapp, on not on chrome. When the device sleeps with whatsapp as active app, then you cant wake and unlock the phone outright using fingerprint..
but if chrome is the active app (whatsapp in background or not turned on), then the phone will be able to be awoken and unlock by finger...
This is clearly a bug. Btw im on 8.5.2.0(stable)

LG V10 Fingerprint Sensor FIX!

Hi there,
My LG V10 finger print sensor has not been functioning lately, whenever i try to unlock the device using my fingerprint, it keeps showing the message " Cover the power key with your finger! ", and it never unlocks, when i go to register my fingerprint, it doesn't work either, but SOMETIMES it works if i push the power button harder and it takes more than 3 minutes to register my fingerprint 100%!
Anybody knows if this is a hardware malfunction or a software bug?
I have tried a factory reset, nothing happened!
Thank you all in advance!
If it is in a case it could be having this issue. There was a software update that fixed it for my Verizon V10. Try with out the case.
hmmm.same with me, on MM. is it not working? pressing power key would give me a prompt that i need to press slowly though.huhu

im having the same issue
same thing here but my started after marshmallow update, i have to wiggle the button with my finger and than it registers. and no its not a case issue. im guessing its the hardware issue.
hmmmm... just wiggling and it worked? we do have the same issue dude
so its fixed or not at MM update?
Mine stopped, I reported to LG, they me send it in and they fixed it. Took about a week
send in repair
hi. After you got the phone back from LG, did the fix last? cause I'm wondering is it just a matter of replacing the fingerprint sensor itself or if it was a software issue which I believe. Because the problem I'm having is that it just doesn't offer the option to open the phone up with the fingerprint scanner but when it does it scans fine although half of the time I have to enter a pin which defeats the purpose of me having the fingerprint scanner. It's like it's being turned off and on or something.

Second s9 since launch with the same exact problem!

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

Miui 10 and DND mode

Hey, I updated my rn4 some weeks ago to miui10 and since then, my DND mode lights the screen up. That's annoying cause I have it always turned on, I hate vibration or sounds in my phone and the screen thing is important cause it stops my music or resets it, or even tries to unlock my phone and it gets blocked.
Is there any way to configure it someway or maybe an app that holds the screen off while it's blocked. I have my phone rooted if need.
Thanks!

Face unlock requies slide to unlock even if checked unlock automatically

Please help, my Huawei requies after succesfull face recognition unlock still slide to unlock with finger, even if I checked in system settings Direct unlock feature under security option. Week ago everything was OK, now direct unlock not working. Any ideas? Thank You!!!
It does that when the face unlock and fingerprint unlock conflict with each other. It happens to me sometimes.
Just try not to use both at the same time by accident. I set my face unlock to only unlock when I'm looking irectly at it.
Thank You, bazanime, disabling fingerprint unlock solved my problem. But it is still strange to me, untill now (few days ago) both unlocking methods worked together...
Thanx again for help
This happen to me when i have finger print snd face unlock activate, and try to unlock with finger print and fail. In that case always recognise mi face but I have to swipe up to unlock 100%, dont know why either

You're welcome, Happy to help. Though I wouldn't turn off fingerprint unlock because it still good, just in case your face is not recognised. Just use the face mostly.

Try the following solutions to resolve the issue:
go to your Settings > Reset > Reset all settings . This will reset all settings, no data or documents will be deleted. Reboot your phone into recovery mode (press and hold the Power and Volume Up buttons simultaneously ) and use it to delete cache partitions (select Wipe cache partition) . Finally select Reboot system now.
Good Luck
Try turning off do not distrurb
It only does that to me when I lift my phone and it doesn't initially unlock with my face, so I mash my thumb onto the screen only to get blinded by the icon showing around the edges of my thumb putting out more lumens than Tsar Bomba, which triggers an epilectic fit of apoplectic rage during which I smash the phone repeatedly into my face and attempt to put either of my thumbs *through* my phone over and over again. That's the only time I see that.
This was hapening to me too !
My mate 20 pro always worked with facial recognition every time but recently worked intermittently, I tried all the usual reset and wipe cache partition, then I thought that the only thing I had changed recently was that smart lock and trusted place was on as I noticed that away from home facial recognition would work but at home it would say 'smart lock recognition successful slide to unlock' even though the phone was set to direct unlock - changed it, now problem it solved so maybe check this.
Update 9.1 solve this issue .. now it is much faster
I already updated to 9.1 but problem still existed, smart lock and turn off trusted place was definitely my problem.
The earlier mentioned "smart lock at trusted place" will ruin the face unlock.
NOTE: Even if the smart lock is OFF, it will interfere if you have some location saved and you are trying to use the face unlock in there. So you need to delete the "trusted place" from the smart location.
Simply turning off Bluetooth worked for me

Question Lock screen asks for pin

Hi,
I am using fingerprint sensor and smart unlock but several times a day and every morning the phone is manually locked and I have to enter my pin again. Is there a setting I am missing here?
same here. also it keeps asking pin through the day!
also I'd appreciate if I won't need to confirm pin once is entered correctly (just numbers then unlock instantly)

Is it that your phone is rebooting? There have been people reporting random reboots with their devices ..

Thats true, the extra confirming is annoying as hell...I think smart lock introduced this issue, so I will try to turn it off for now...

I have not noticed any reboots yet but I dont think that the problem. I still see notifications on the lock screen. I believe that would not be the case if the phone rebooted.

Smart lock relocks after 4 hours of inactivity and apparently defaults to PIN or Pattern, not FP.

Doesn't seem to matter whether it's active or inactive. It seems to re-lock and require a PIN every 4 hours.
Extremely annoying. SmartLock on my Samsung phone didn't behave like that.
Disabling smart lock fixed it for me, make sure are smart lock triggers are gone

So now it is always locked and the FP is the default? I like having it unlocked at Trusted Places for 4 hours better.

I might just try this. I used smartlock on my Galaxy s20 FE because the fingerprint sensor was way down at the bottom and was difficult to reach, so I would just press the power button and swipe up on the screen.
However, I discovered with the Pixel 6, that when it's smart locked, if you just touch the fingerprint sensor icon, it turns on the screen and opens the phone. (without it actually triggering the fingerprint sensor) No pressing the power button or swiping required.
So I've started getting into the habit of just pressing the fingerprint icon anyway, even when it's unlocked with smartlock. So, as long as the fingerprint sensor is reliable enough, I don't really need the smart lock. I would be doing the same motion to unlock it with the fingerprint. (Although it will be a little slower and possibly a bit more unreliable)
Well, I don't think it's smartlock related. I turned off smartlock a half hour ago and used the fingerprint sensor to unlock it several times since then, and then a couple of minutes ago, it forced me to enter the PIN. Almost exactly 4 hours after the last time I had to enter a PIN.
I was wondering exactly the same... it's a weird behavior.
I think it may be a 'feature'. A fingerprint is considered somewhat less secure by Google. Ironic, given on a P6 it seems to lock folk out a lot of the time!
Understand fingerprint security - Pixel Phone Help
Your fingerprint data is stored securely and never leaves your Pixel device or Nexus phone. Your fingerprint data isn't shared with Google or any apps on your device. Apps are notified only wheth

As you say, annoying though.

Did you reboot the phone after changing the smartlock setting? Perhaps the phone has held onto that setting in memory.
i am having the same nightmare here. Considering i am wearing gloves most of the time, i need to usesmart unlock. but then every few hours i need to type pin, plus i need to press entre. it really breaks flow here

Smart lock resets every four hours, which requires you to enter your PIN to unlock for another four hours.
Confirming a pin makes it more secure, as now the number of digits in your pin is also hidden. In theory, this would make a 4 digit as secure a as 10 digit one as a potential thief would not know which to try.
