Fingerprint never works :-/

Hello guys. I am having fingerprint issues in ROMs based on CM / AOPS. When I install a ROM, at first, it works normal, but with two days or more it gets very bad. It is difficult to register new digital ones. What can it be?
Have you tried RR?
try aida64 app to see which finger print sensor u have flash kernal which support it . it will work bro
Search for MIUI MM firmware for redmi note 3 and flash it.I faced this problem too but after flashing firmware it worked
Sent from my Redmi Note 3 using Tapatalk

What happens if i flash a modem firmware.

if i flash a modem firmware with my current custom rom.
And then if i clean flash another rom after that should I need to flash modem firmware again or the modem firmware will stay with my device???
If that stay in my device then what i have to do to remove it in future if i need to.
Also tell about kernel???
What is black screen kernel???
If i flash it what kind of changes come in my device???
Heyyo, modem firmware is separate from your ROM so there is no need to worry about reflashing.
The kernel is essentially the interface between the hardware and Android. Some are built for performance, battery saving or a balance between them.
Blackscreen Kernel is currently the most optimized kernel with a little more emphasis on performance than battery saving. It is built for Nougat ROMs and there's a bunch of ROMs that actually include it already such as BlackX, Slimroms, 1nfrag's AICP builds, Andr68rus's Dirty Unicorn builds and his Paranoid Android builds. Custom ROMs require a compatible ramdisk for Blackscreen kernel to work so it isn't guaranteed that ROMs without it included will be compatible.

All you need to do is reflash whichever version of modem firmware reflects the EUI ROM version your phone came with.
For example, my x829 came with NA 16s so I'd flash NA 16s modem firmware.
I haven't seen any need to revert to a worse modem firmware though as newer ones have improved my signal reliability plus fingerprint reader performance when the device is asleep.

Hi.
My device came with "Indian 16S", but the fingerprint function was not very responsive. Updated to Indian 19S and the fingerprint become very responsive, but only for 5 days, so it became poor responsive. Tried calibrate, add new fingerprint, but after and after these processes, it became like "dead" (no response at all -- even a vibration; nothing). "Fabric Restore" the ROM did not change the situation, and update to Chinese 23S and Chinese 26S did not turn the fingerprint sensor back to life. So I tried the "QFIL process", but even with the DEV ROM, nothing happens to capture the fingerprint. So i installed TWRP to change ROM (the DEV ROM does not update with any update.zip stock ROMs - "corrupted file" error) to Indian 16S again, and updated - by "update.zip" file (now it works) -- to 19S again. The device still not capture any fingerprint, but it's not completely dead, but a sort of crazy, because if the "tap to shoot" function is enable, the camera app shoot -- "automagically" -- photos like a crazy gunner...
What can I do? Is anything that I can can do to get the fingerprint sensor "normal" again? My device is with the 19S Indiam ROM again and the modem is ".2.0c1.9-00033-M8996FAAAANAZM-1" -- (is the 00"033" version?)
Can i change for another better modem version? Maybe the fingerprint sensor became less "sensible" and capture fingerprints again -- and not shoot photos "automatically"...
Best regards.

You can always try a different version sure! Modem firmware developer 466D might be the newest one
https://yadi.sk/d/woKdrlRrv8yhr/Для разработчиков
Otherwise it seems thus far modem firmware 23s, 26s and 28s are all the same for the latest stable

I had no success. Installed "466D_V.00050" modem zip file on TWRP, restarted, confirmed the new modem version on "About the Device / Base Band", but the fingerprint sensor on fingerprint register application still unsresponsive. I also installed "CN_26S_V.00033", same result. So, I installed again the "466D_V.00050" only to test if a new Stock ROM subscribes that. I updated (update.zip process) the 19S Indian ROM with the CN 26S ROM, and yes, the modem version turned to the CN 26S version (MPSS.TH.2.0.c1.9-00033-M8996FAAAANAZM-1) -- without any modification on the fingerprint malfunctioning.
If I had any updates about the fingerprint problem, I'll update it with a new reply on this topic.
Thanks.
Best regards.
Ah darn! Hmm I'm not too sure then sorry friend... I remember seeing a topic before where a dude had the same issue and ended up replacing the fingerprint reader hardware and got it working so sadly you might have to do that or even maybe opening it up and reseating it?
I'd check for that thread or research the price of the part plus a suction cup to take the screen off and replacement adhesive tape there's also some videos on YouTube for opening up the Le Max 2 with a heat gun or hair dryer that's what I had to do to replace my screen before but I've never done any other hardware swaps yet
I am still using modern firmware of INDIAN 19s.
I am unable to make carrier Video call everything else works fine.
Is flashing CN 26s modern firmware is gonna help??? ( Because my device is Indian x821)
I am checked carrier video calling with LINEAGE OS, MOKKIE, AOSP EXTENDED not worked with any one of these and currently i am using Pixel Experience Rom and carrier video call still not working .
Please Help.
Thanks.
Which modem firmware is the latest, 466D or 30s?
Pls send the link also, thanx.

Heyyo @digitaldevil hmm can you please provide more information?
Which version of EUI ROM is your device on? Is it still 5.8.016s?
Have you tried upgrading to the latest EUI 5.8.023s stable ROM?
Or have you tried a custom ROM?

Hmm sorry to break the news to you bud but the 16s is a modified version of EUI ROM by the vendors who sold you the phone. Mine had the same 16s and it sucks. YouTube would randomly freeze the video feed but audio would keep going and notifications would fail to pop up because of the aggressive memory management 16s has.
The only way to flash to Indian 19s or Chinese 23s (the stock version of Indian 19s isn't so bad but Chinese EUI ROM builds are atrocious and filled with bundled garbage software and you have to try modding in Google Play if you want it..) is to use your PC and fastboot flash those ROMs.
Here's a guide about it but it does require unlocking your bootloader to flash a different version of EUI ROM since 16s is update blocked.

Suggestions On Custom Rom.

Hello guys how you all doing?
So i have this Device for about 4 months and i wanna try some Stable or Daily Usage able rom. I did try some like Havoc 3.0, And Pixel Experience also Miui but in Miui i have faced bit of shuttering which was anonying so i went back to Stock.
Now from users who tried lot of Roms and kernels can you guys Suggest a Rom for Daily Usage with Good performance and Battery ? also a stable google camera would be nice.
there is lots of custom Rom so i need some suggestions, also i need customization. so PE won't work for me.
In my Past Device Redmi 5 Plus Havoc was the daily since it was official and Bug free.
Thanks
Regards.
If this is the wrong sections am sorry please move this thread thanks
Only MIUI.EU has ability to unlock phone with fingerprint when phone is sleeping. I don't recommend miui eu because it starts freezing after few days and one week ago my device completely freezed and tried to restart but it bricked. I also don't recommend pixel experience because you can't unlock with fingerprint when phone is sleeping.

MIUI 12 bluetooth issues with car infotainment and continuous disconnections

Hello everybody,
I own a Xiaomi MI 10 with the latest stable MIUI 12 EU ROM,
since I did the update from MIUI 11 I am having problems in pairing the phone with the VW e-UP infotaiment system (called Composition Phone).
In practice, once paired after a few seconds it uncouples and then after a while retry a new pairing which after another few seconds it disconnects and so on ..
I tried all the developer settings a bit but they didn't help.
I also noticed that going to the bluetooth devices of the phone, if I tap on the name of the infotainmet just before the automatic procedure starts, then the pairing is successful and no longer disconnects.
Anyone have the same problem with a VW? is there a solution? I also installed Magisk, is it possible to patch the bluetooth libraries?
Same exact machine and exact same problem.
You Found solution?
I am waiting for xiaomi to give me the code to unlock the bootloader and I will go back to the UMIGlobal_V12.0.1.0.QJBMIXM which worked perfectly for me.

Great! it's nice to know you're not alone where are you from?
I can tell you that I tried the latest EU ROM and it didn't work, but the EU compared to the global one has several nice features more. Since you have to unlock I advise you not to put the global again.
Before downgrading I would like to try the ROM EU weekly which if I have not misunderstood is based on the MIUI 12.5 beta, but for the moment I have not yet done so ..

Even the weekly does not work
I finally managed to solve the problem with the ROM
xiaomi.eu_multi_MI10_V12.0.8.0.QJBCNXM_v12-10.zip
which also works very well .. In any case I begin to think that it does not depend on the MIUI version, but on the version of android. I think the bluetooth management problems are due to android 11.
A bit late but have you tried changing the Bluetooth protocols in developer settings? You can change the version etc..
I have a new e-UP since yesterday.. same problem here with MIUI 12.5.1.0 on Poco F3.
Any solution without downgrading the rom? (MIUI 12.0.5.0 is also Android 11 on F3)
I think i will go for a Custom Rom in the next few days..
Does the latest Maps+More update changes anything? It says "Android 11 compatibility"..
HI Guys,
For me this problem is still alive. I'm running a VW E-Up also and since updating to MIUI 12 my car bluetooth is unusable as it constantly connects and disconnects to my M10 every 5 seconds or so. I've experimented with many settings changes, along with unpairing and re pairing but all to no avail.
I'm running 'Maps and More' ver 5.0.0 also but it's useless as I can't stay connected long enough to do anything with it.
Has anyone found a fix without downgrading?
Same problem here... any news/solution?

Hi guys,
I have similar issue since version later than 12.5.3. I even changed my phone to other xiaomi model, the issue remains.
So I will flash back to 12.5.3 if the issue cannot be solved in 3 months...
Now I have to turn on and off airplane mode to temporarily solve the issue every time I need to use Bluetooth related functions.

Hy folks,
Idk if the Bluetooth is the same but I got the skoda citigo with the Garmin device. Had the same issue. The resolution for me was to activate developpers options and change the Bluetooth Codecs to what my GPS device supports as it was way older than the one build in my redmi note 11
My perfect solution: I deactivated the work profile, and eveything is fine again!
