Hi there! I recently bought Xiaomi 12 Pro Gloabl MIUI 13 and I faced really annoying problem. The proximity sensor does not work and it did not pass the test. Allays shows 5.0 at the test no mater if the sensor is covered or not. And the real problem, the big one is face ID does not work at dark, like there is no IR at all and that is great issue for me, because this makes phone completely useless for me while traveling at night.
What I red the proximity sensor is virtual instead of hardware and it makes problems and user waiting for software solution for years. OK, but what about IR camera for face ID. Is it integrated in this phone or not. I find no answer.
Planning to switch to xiaomi.eu rom hoping for fix, but...lookin for solutions with golobal rom, because I use a lot of banking apps that I`m not sure if they work wit unlocked bootloader.
There is no IR cam, just the regular one.
That's not a 12 Pro only issue, most phones behave the same in the dark.
You can however use the fingerprint, so where's the point of calling the device useless at night?

The point is, when the phone is in holder I just tap on the screen and it unlocks by face ID immediately. That`s I have used with Mi8 till now. Fingerprint of 12 Pro is very slow compare to Mi8 and mostly unlocks with second try.
Well I have to adjust to new lack of hardware, but quite expensive Xiaomi

Try to register your finger a second time as an additional finger. This could help to speed up the recognition.
I faced proximity sensor problems with my 11T Pro but the 12 Pro is working great. I use the fingerprint which for me is lightening fast. Unfortunately without the front IR sensor, no photos going to work like iPhone when it comes to face I'd.

Hi did you try to move the phone towards your hand during the test? because this movement simulates the gesture of answering a call.
Enable double tap to wake, then unlock with index finger
PS Don't use phone while travelling

I'm so frustrated with my S10 scanner that I've decided to return the phone back to Samsung. I can't accept it in $1200 phone. I need to open the phone in an instant like I do on my $200 Moto X4, it's slow but it never fails.
My question to all of you, S10e owners is: does the side sensor on 10e works as supposed to? Am gonna take chance with it, I really like the S10 series, great phones, but they didn't make the sensor on 10/10+ right.

I have S10e and the fingerprint sensor is in the power button and for me it is a learning curve, but it unlocks fast. I had to re-register my fingers again after learning how to comfortably put my finger on the sensor.
I have an S10e. Although I wish the power button/fingerprint reader wasn't so high up on the side, it's proven to register my finger perfectly every time. Plus, it has the gesture option like on last year's models. Swiping down on the fingerprint reader pulls the notification menu down. That's pretty neat.
I'm very happy.
I must be lucky on my s10+, postponed update, did not adjust fps settings and it is working really well for me

S10e fingerprint works like a regular fingerprint, more accurate than those under the screen and quite fast (but not as fast as OnePlus 6 per exemple).
It unlocks the first time like 99% with my right hand, but is more unreliable with my left hand.
If you hold your phone with your left hand, I wouldn't recommend it.

I'm right handed and was having issues at first, but then I scanned my thumb when the phone was flat on the table and again when I was holding it in my hand and I've had much better success with unlocks.
Only time I mess up is when I don't get the placement just right, but that's more about getting used to under display fingerprint readers than anything.
i'm also very disappointed with this, hated it on the back with with my S8, this is the only reason I bothered upgrading, it only works about 50% of the time as you need to get it right on the mark.
What more infuriating is all the reviews show it working 100% of the time when its clear this is never going to be the case as the sensor is very small and very easy to miss.
effing useless, also considering returning it.
EDIT - i removed mine and put them in again, seems a lot better now, still not as accurate as review make out but now usable for me.
Did you guys try the under-display scanner after the day-one update ? I read it works well afterwards.
I think most people just need to get use to it, my first 12 hours or so I was frustrating as hell but the more I use it the more I'm getting use to it and now its working flawless for me and thats with the screen protector still on. I have both my thumbs and index fingers set to it and they all work great.
its occurred to me what this solution needs, an always on fingerprint icon on the screen when its locked, it will need to be quite dim and pixel shift in order not to burn in though.
Thank you guys for taking your time to answer, my S10 is going back(rma issued) and I've placed an order for 10e it'll ship on 3/14. As great as all those S10 phones are, it's really bad if you can't turn it on.
The position is a bit too high if you're left handed or using the phone with your left hand. Other than that, It's pretty reliable and pretty fast. I'm quite used to side the mounted fingerprint scanner on the Xperia XZ1 Compact and this one is definitely faster.
It also allows you to choose to have it always active (ie. you just need to place your finger on it) or require you to press the power button (maybe to avoid accidental unlockings or recognition). Oh and it also keep the ability to swipe to pull down the notification tray which is handy.
So far I love everything about the S10e except the software...much thanks to Samsung caving in to Google and blocking rootless Substratum. I haven't switched from the S7 to it yet because I'll have to root the phone for the first time to solve that customisation problem that irks me to no end. If, however, you don't require Substratum to be intact, you'll love the phone from day one
I'm returning my S10, the fingerprint scanner annoys me. I came from the 6T and thought the "ultrasonic" would be much faster and accurate, yet it is not. I'm thinking about the 10E, but the screen is a little small.
I'm debating if I should stay with the 6T or get the 10E....
I'm also returning s10+ for fingerprint reader, considering s10e, small screen isn't so much of a turn off as the small battery
the 10e will be my choice as a screen crack or damage can make it not function and what I read about protectors having issues over the scanner - meh... the button method seems far more reliable and ideal to me.
Yall know and update to fix the finger print reader is rolling out to fix the issues. As well dry hands are causing problems, try getting your hands moist then try it. It works much better for me and I don't have the update yet.

There is no such thing as a 100% reliable fingerprint sensor. In fact nothing is 100% reliable everything will at some point fail.
this is now a single frustrating issue on S10. fp is still very poor. Error rate is very high, speed is terrible (huge post fp delay, huge delay during recognition too, the reader literally waits until finger is released). Also coming from 6T and Mi9, which were much better and lightning fast.

Oh yes... the S10 fps rehashed! Been using my S10e for a while now and have no complains – except for the lousy updates distributions on part of Samsung. Securitywise, my SM-970U1 is @ May 1st as of Aug.3rd
Am gonna say the side fps is close to but not entirely perfect, very reliable, still. I use 3 fp(am right handed) Lhand index, Rh thumb and Rh index for an easy use. I can pick the phone off the desktop with my right hand simultaneously placing the R.idex on the sensor to turn the phone ON instantly. Or, I pick it up with R hand and place it in my L.hand palm reaching for the sensor around with L.index – don't even have to look at it, the phone turns On. Am using the R.thumb when I already hold the phone in my right hand but the screen has timed out. And I really love the so-called “small factor size” so easy to handle in and out of the pocket.
But frankly, I really miss the back sensor location, had S9+ and OP6 for a while before S10 now S10e and the back location was the best! Turning the phone On was done almost subconsciously by slipping hand into a pocket and touching the easy-to-feel dimple on the back cover.
Hi, I have this problem with the fingerprint reader under display of my xiaomi mi 9.
When it is resting on a surface I cannot unlock it with the fingerprint, I find this very annoying especially when I am at work and the phone is resting on the desk and I would like to unlock it, or when it is on the bedside table. The only way that allows me to unlock it with the sensor under the display is to take it in hand and unlock it.
I did several tests and I noticed that it is enough to touch the metal frame with a finger to allow the phone to unlock with the fingerprint reader. Alternatively, just have the USB cable inside the door.
If it is on a surface (for example a table or a desk) it does not allow me to record the imprint because it does not even detect the finger.
I don't understand if it is a thing wanted by xiaomi or it is a problem?
I leave below a video where I show what I said.

After Global Beta 9.5.9 Update
https://forum.xda-developers.com/showpost.php?p=79507139&postcount=26
https://youtu.be/Ve6eCVPhcY0
That is really weird
I have the same problem. It is quite weird that sometimes the fingerprint is working ok, sometimes it doesn't work at all, especially when on flat surface like in your example. I think it is working better for me now, after having erased and registered fingerprints again. Also, I feel that slightly "rolling" your finger on the fingerprint is working most of the time (for example put the left side of your fingerprint on the sensor then roll it to the right side, it should work better). I am on latest Xiaomi eu rom (9.5.1) and it seems a bit better too (or maybe I just get used to it!).
My FP is good, doesn't have the problem like you said. On flat surface or anything, it's working. I'm using Xiaomi.EU Dev 9.5.1
Try to add same finger multiple times like fingerprint 1, 2 3 and 4. That's what I did and it is now better.
I'm on the last Global Beta (9.4.26) and before last EEA but the problem persist. I tried to record several times but without success. When the phone is resting on a surface it does not work. If it's in my hand it almost always works perfectly.
I can try to install the .eu and see if there are improvements.
I have the same issue on lastest EEA update. When the phone is on flat surface, the sensor barely recognizes my finger input. Im pretty sure that was working fine before the last update.
I hope this is a problem that can be solved via software with a future update. The point is that some have the same problem as me, while others work perfectly in any situation. So it is difficult to understand what is wrong.
I have the same issue. It almost never work unlocking in flat surface. The only way is to press the sensor really hard with force, then it will unlock. I have similar case in redmi 3x, the screen dramatically lose sensitivity in flat surface. I dont know what causes. Maybe it is related to electrical grounding.
Can anyone make a thread in miui bug report forum? I will support it..

Same problem for me with last EEA 10.2.24
If phone is on a flat surface the fingerprint seems to stop working
Last update was ok

Yes Mi Forum is read-only since today, they want you to use Mi Community instead, but looks more like a Facebook group than a serious forum.
For me (latest 10.2.9 Global ROM), the fingerprint when flat on a surface works just fine; but as others said before, try re-adding your fingerprints using more different and wider angles; perhaps your finger was at 0 degree when you added the fingerprint whilst in real-life practice your finger is usually at 15 degrees. Making sure you cover all the sides of your finger helps (I have 5 fingerprints for 5 fingers registered, one was responding badly, so I readded that one and it works fine ever since).
But perhaps its indeed (latest( EEA ROM related ?
Same issue with the latest Global Beta, sadly.

Hi. The problem is that seems like the fingerprint is disconnected. It doesn't react to any finger, it doesn't turn on. As soon as you pick up the phone it works flawlessly with any of the registered fingerprints.

I had the same problem on stock MIUI, with locked bootloader. Now I'm on Revolution OS and the problem seems solved, so I think it's a software issue.
Anyway when I had the problem, when the phone was on flat surfaces, I used to put my thumb on the bottom frame of the device, unlocking with the index (so using just one hand), and it worked perfectly. You can try this as a temporary workaround waiting for a software fix.

Ok, that clarifies things; I thought it was conditionally unresponsive or inaccurate, but what you describe seems like the wakelocks are too aggressively set., very typical of MIUI.
Normally one would go Settings | Battery & Performance | Power Usage, and in the top-right hamburger-menu select 'Show System Apps' and select the Lock Screen or Fingerprint / Biometric services app and disable it's 'Power Restrictions' , but MIUI hides all most internal services.
Instead, download the MiAppa and click the 'Battery optimisation' tool; then in the blue title/dropdown bar select 'All Apps' instead of the default 'Not optmised' ... now a lot of internal services and components show up. Scroll down to 'MiuiBiometric' and changes it's 'optimize' setting to 'dont optimize'. That might help with it's wakelocks being filtered. I haven't tested the setting myself - and there are a lot of other system services that might be relevant to test - so please give it a good try.
Alternatively, run a custom ROM or enable the double-tap to wake (and/or pickup to wake, but I think you already had that active), so you tap to 'wake' it, and then the fingerprint does work instantly. Internally in 'deep sleep' state it might not respond to the fingerprint directly (i.e. after a few minutes idling with screen off), whilst screen-off idle before the deep-sleep state still works fine ...
Latest 10.2.24 EEA, zero problem.
Cue the "omg omg I have a bad phone how to fix plzzz"

Thanks. I've been trying what you said without success. Doesn't matter if the screen is on (on lock screen) or off. It seems like you need to be touching and holding the device with the hand.
What is surprising me is that if I am touching with a finger the frame of the phone in the usb port zone (the only part exposed as I am using a Nillkin cover) then seems to work the fingerprint sensor.
The problem only appeared since the last update so I am pointing to software error. I've reported to Xiaomi through the app.

Have you tried unlocking with fingerprint in lockscreen (screen on)? Doesnt it different from the phone off? Mine is still same. When screen on, it should not be optimized.
Well, trick of unlocking with finger hold in side of phone seems help, but not much.
Plus add this trick, register your thumb 2 or 3 times, focus registering and unlocking in the center of thumb, not the tip. Dont use index finger. These combination of tricks really help for me unlocking in flat surface.
Hi,
Using the Red Magic 3 is quite nice, but one of the major problems to me is the FingerPrint scanner.
It happens really often that I have to "press" the FP scanner several times before it lets me in
But on the other had, Face unlcok works superbly here !
It recognizes my face everytime, even in rather dark environment.
And unlocking is then super fast...
Guess I'll use that more often than the FP scanner
You guys also have that "problem" with the P scanner ?
No its working perfect for me, much better then the fp sensor of the xiaomi mi mix 2 (my prev phone). Meaby try to set it up again?
I had the same problem, then it went away, then it came back.
Saw some people complaining here as well on github.
Funny thing for me, seem to be related to having activated multiple users in this device and for some reason the finger print only works (normally) on this second account. Deleting that saving account did not solve the issue as the sensor continues completely irresponsive in my main account (so it's clearly just a software issue). If I recreate a second account it will work there, but still not in my main account.
Do you have more than one user registered for that device? I use the other users mainly to have alt accounts for different games
I'm in touch with their (slow) support and the last message I got was:
We will feedback this case to our R&D .Pls provide the order number and Build number of the phone.If you can, please also provide a video file of this process,thanks.
In my case it's clearly just a software issue, so it should be fixed in future builds (hopefully).
Perhaps a factory reset would help, but I don't want to test that option as I'm lazy to set up everything up again.
Hi,
Same thing here.
The FP scanner is not on par with some of the RM3 sibblings like the Mate 20x or the mi mix 3.
I think the scanner is too small to recognize your fingerprint decently.
But if I compare Face unlock on this device to face unlock on the afroementioned devices, it's a totally different story !!!
It is amazingly fast and reliable, even in low light conditions...
So I am almost always using that one.
Regards.
No problems here with the FP scanner.
I'm on Global ROM,bootloader is still locked,no root and only my account registered to the phone,but I've setup 4 fingerprints,and all of them work quite good....
My mom was trying to register her fingerprint on my Mi9 but it was a very difficult task since the scanner couldn't detect her fingerprint. After a long time and being able to register the fingerprint, now it's near impossible for the phone to scan her fingerprint and unlock the phone. Meanwhile, my fingerprint unlocks easily almost every time, so I really don't know what's happening and how can I fix this. I'm using MIUI 10.2.26.0 EEA. I wanted to put the global beta to try, but since they won't update anymore global betas I stayed with the global EEA.
She's looking for a similar phone, but if on-screen fingerprint scanners have a problem with her fingerprint, she will have to stay with standard fingerprint scanners that she never had a problem with.
I'm currently using a screen protector, but since it works great with my fingers, I don't think that's the problem.
Are there any tips on fixing this problem or at least make it better, like finger positions or doing something with the finger before scanning, without having to change ROMs?
If it works ok with your fingers, "probably" not a sensor or rom problem.
I always register same finger twice for better reading, but if your mom's fingerprint is washed out, will never be 100% efective.
so in short this problem has plagued the phone since day one and i suspected a HW issue since nothing fixed it. for those who dont know whats im talking about, you are lucky. the issue is basically that the proximity sensor is missed up so the screen will light up when you are in a call or listening to Whatsapp/Telegram voice messages.
The Solution:
The problem, turned out, was caused by the factory screen protector that came already applied to the phone. i removed it after it was damaged and also removed the case (Spigen Rugged Armor Case), cleaned the phone and VIOLA its working perfectly fine now...
i hope it works for everyone else.
So, what you are saying is:
Since when this phone got launched in May 2019, not a single user facing the proximity sensor issue had the ingenious idea to remove their factory applied screen protector and you are the first one to come up with this "fix"?
I am really sorry to be this discouraging but: This ain't it chief.
Good that it fixed your perception of the issue though
Comrade, the issue is far graver than that. OnePlus 7Pro does not have a proximity sensor per se. It uses software (an ai I think) to "guess" whether to turn on the screen or not which is why listening to voice notes gets crazy...

Even though it does have an infrared sensor under the screen (that has been proven), i agree with you that it seems to be using something like that.. Curiously, the proximity sensor once fired when i flicked off my lights in my room.. This indeed leads me to believe there is more going on than just a simple infrared proximity sensor..
But yeah, i don't think removing the stock screen protector "fixes" the thing.. It may improve things but i doubt it's a fix.. As i said, this phone has been out for a while and people would have noticed if removing the screen protector fixes the proximity sensor for good..So yeah, cheers mate.
I took the screen protector off before I turned the phone on for the first time. I still get the screen lighting up while I'm on a call, often muting it with my cheek.
I must be lucky but at the moment I have no such issue with my new OP7P (MFD: 2019/05). RR Rom. Still have the screen protector on it. What's the MFD of your unit ?
i have problem with my oneplus since i rooted this phone
after root i have installed pixel expereince rom
when i called i found proximity sensor not working
now almost 6 months no fixed i'm stock oos
please help me there is no guard on my phone also no cover
The simplest solution for me has been to use a Bluetooth headset. I rarely use it without it.
