Has anyone experienced problems with the fingerprint sensor where it stops working randomly? Rebooting the phone fixes. Running the finger print diagnostics shows no issues. I'm running the latest miui, it's been happening over the last month or two.
Nope. No issues here. Also on the latest global rom 8.9.20

Goodix FP
It happened to me the last week, i ordered a new fingerprint sensor, but i believe is a software issue since aida64 detects it however when i press 4 times the kernel version it jumps to CIT you'll need to go to the #30 and see if the Goodix FP works with the test.
For me it does not come up, it's just showing empty, hope i get some luck with this without the need of disassemble the back of my phone in order to change it, since it just stopped working suddenly.
I'll proceed on unlocking the phone and check what else needs to be done, while i get the replacement.

I already unlocked mi Mi MIX 2s to no avail. Fingerprint scanner does not show in the #30 in CIT. Aida64 detects it but does not work either.

Which os have you installed, any kernel change? have you requested the fingerprint sensor?

MIUI 10 - Stock Kernel - I still don't request the fingerprint sensor.
I tried reinstalling latest MIUI 10 global stable and worked once. After that, fingerprint scanner stopped working again so i reinstalled MIUI 10 but to no avail this time.

I just have installed Pixel 3 Experience ROM (https://forum.xda-developers.com/xiaomi-mi-mix-2s/how-to/rom-pixel-3-experience-t3855300) but fingerprint scanner still does not work. It is not recognized by the system, but this fingerprint sensor test app (https://play.google.com/store/apps/details?id=com.rhkr8521.fingerprinttest&hl=en) crash everytime i run it.
Anyway, i'm not sure if this is a hardware or software bug. Maybe some fingerprint sensor driver got corrupted or something...

Most likely is a hardware failure. I have installed so far Revolution Remix, MIUI 10 and Pixel Experience and fingerprint scanner does not work with any of those.
Have ordered a new fingerprint sensor so will report back with an update once I replace it. Almost certain it's a hardware issue.
Update: Successfully replaced my Mix 2S fingerprint sensor today, took about 30 mins as I was quite careful.
I had to heat up the bottom third of the back of the phone to 80 degrees Celsius (back is glued on), did that with a heatgun. Then I used a tool to wedge apart the back of the phone from the rest, had to unscrew a section, remove the fingerprint sensor, replaced the sensor, re-screwed the section back in place, put the rear cover back on the phone. Turned the phone back on and voilla, new fingerprint sensor working beautifully. I had to remove the existing fingerprint profile that was there and create a new one, but working rock solid now.
The sensor is very cheap ~$5 USD, with cheap international shipping. I'd recommend everyone try this who is having issues with the finger print scanner if resetting the phone didn't help. Get it from here:

Get something like this for the job:
https://www.ebay.com/itm/20-in-1-Mo...h=item1c82e9f38a:g:--wAAOSwE0JY-Oal:rk:1:pf:0
Same issue now with me. Already replaced the sensor. No improvement. So you have the goodix or the fpc sensor? You can see at the Cit (4 times Kernel touching)
It is a hardware problem. In fact, a manufacturing process failute. The flat cable was bended (probably inattention in the assembly line), so it broke. So all of you with the problem, it's a matter of time it completely stop working.

Hi all, I just got my s7 (Hongkong, 8890) last week and it was perfectly fine until today when i was using whatsapp - i could ONLY play audio notes through the speaker even if i brought the phone close to my ear (I checked and cleaned at least 3 times so nothing is blocking the proximity sensor. )
I then proceeded to make a phone call to try and as expected the screen won't turn off when the phone is brought close to my ear.
So I dialed *#0*# to see if it was whatsapps problem or it was the phone - turned out all the sensors including barometer, accelerator ...etc have all failed to give any response. The readings were all 0 when i was shoving my phone like a mad ***** lol
Anyway I restarted once, didn't work. Twice, works like a charm again.
Thoughts?

I have the same problem where I suspect that it is software that controls the sensors that stopped working after updating the firmware of the phone.
I am still researching a way to correct, in case I find something I keep you updated.

Android 10 is here! You can now update to 52.1.A.0.532.
Dark mode is here! Launcher was not updated, so no gestures, and things like the Google search bar stay light in dark mode as a result. Recent apps / multitasking is the same as it was on Pie.
Digital Wellbeing and other Android 10 goodies are of course available.

Frustrating no gestural navigation ?
I was waiting this major update to unlock bootloader and root my XZ2 Compact, let's hope I won't lost features like camera (normally not since Android 9)
Camera api still not support RAW
I installed and I must say the animations don't seem fluid, the phone is lagging overall since the update, and the fingerprint scanner isn't responding properly

Same problem with the fingerprint scanner
Hello, I'm new but I want to share this update with you.
I did an hard reset after the update to avoid dealing with fixable issues.
Fingerprint require lot of touching if the screen is off.
Recorded mic audio is low. Never been that high though.
Camera often crash when opened or freeze after taking a shot.
Once in call they stopped to hear me on the other side. Needed to restart the call.
No gestures, no new app switcher. Same apps. Got the the wellbeing tool, smart answers, dark theme, system updates trough play store...
Battery and perfomance are fine on my terminal. I use only one sim and no memory card.
I will edit this message while i discover new issues.
Got the Update today. Xperia XZ2 Compact.
Immediately after the update process i noticed a significant drop in microphone volume (microphone sensitivity) when recording voice messages.
Can somebody confirm this systemwide issue?
If yes, is there a non-root solution or even a new setting involved?
(My volume settings are all at maximum)
I also confirm fingerprint issues
Slow fingerprint scanner issue in here too. Takes about a second of two to unlock the device when screen is off. However it's faster with screen already on.
Good to know Sony is subjecting its latest software to intense Delta testing.
I might skip the update until they get the kinks worked out. Remember how much fun the connectivity issues were a few updates ago?
Just updated - I noticed just one (SIM1) operator name on lock screen. Dual sim feature is working fine , signal bars are visible just not displaying SIM2 operator - any hint? Fingerprint seems fine to me.
About the fingerprint problem: Its completely fine if you wake the screen first with the power button. Maybe its intended: I had a lot of issues with accidental unlocks.
Still, annoying.

If it is intended, it is a massive step backwards. The less you use the power button, the better.
I like fingerprint to wake and tap to sleep.
They even removed the activation of the fly mode in "night action" from Xperia assist, wtf is wrong with them ?
Gonna downgrade asap.
Warning ⚠
Anyone reading this before updating! Don't update now! I repeat don't update now! Or you'll be looking for downgrade tutorials by the end of the day

You're right, I did and now I meet huge battery drain :silly:
Is there a way to swap button on navbar ? I mean reverse recent and back button.
what does Android 10 add for the XZ2 Compact since Sony excluded features like gestures? system dark mode is nice, but it's not that important for a LCD screen phone like the XZ2.
Anyone know if the update has been pulled? Been spamming the update button and nothing is coming up. Anyone can comment if update is really that bad ?
I need 5-10 times to open my phone.

That is not normal, the fingerprint is very accurate on my phone, my old s10+ had an horrible fingerpring sensor...
The fingerprint sensor seems to work well in my S21+, but sometimes, after I authenticate with my fingerprint, I get a black screen with a white round icon with a lock in the button of the screen. It doesn't happen all the time, but I've been unable to identify the condition that causes it to come up. Does anyone else get this secondary black screen or knows the reason for this annoying secondary screen?
Some tips I can give are:
1.- Delete all fingerprints and add them with the scren protector, pressure before the scren protector is different.
2.- Enable enhanced touch sensitivity.
Keep in mind that under display fingerprint readers are not really designed to work perfectly with screen protectors. I had that issue with the Note 20 ultra and I've read about the same issue with the s21 ultra and s21 plus. Im using the scren protector that came from factory (I know it doesnt really protect) but fingerprint sensor is blazing fast.

I just realized that this secondary screen only pops up after I use fingerprint sensor from the AOD screen. This secondary screen doesn't show when I use the fingerprint sensor from the Lock screen. Why have the ability to use the fingerprint sensor from the AOD screen if it's just going to take you to this alternative black lock screen?

Maybe a bug...This secondary lock screen only comes up when I set "Show icon when screen is off" to (On Always On Display) under Fingerprint settings. If I change this setting to (Tap to show) the secondary screen doesn't pop up. Not a show stopper, but a little annoying as I have to tap the screen to see the fingerprint icon. Anyone else getting this secondary screen after using the fingerprint sensor from the AOD?

I did'nt believe it would do the trick, but it seams it did =) 1hour intensive use with a lot of cpu/gpu/ram load, not a single hang.
I'll write here if the hang occurs again. Maybe too soon, but in case it works "Thank you"

New update, arrowOS has a function which let's you turn off the phone and if you turn it on again fast enough it doesn't asks you for the password, its also fast enough that its almost unnoticeable, for gaming it wouldn't work but for day to day use its great, and let's be honest this phone was never meant to be used gaming anyway.
I also tried rooting and using magisk to install the magisk module of touchscreen by weareravens, I did notice an improvement, but its definitely still there, I think that's it folks, annoying but unsolvable.
I highly recommend installing ArrowOS its infinitely better, you do lose a couple functions like WiFi hotspot, and google drive access from applications( although I'm 70% sure I installed Gapps wrong) and the ability to use some of the banking apps ( I may have lost this when I rooted, I didn't check before and I think I could use them if I really wanted). It may sound like a lot, but honestly those are all the critics I can give, everything else is better on ArrowOS.
I have found a solution that has worked better than any other thing, you need root acces.
Touchscreen Issues
Hi Guys; I recently got my new 2nd Generation Moto G but after setting it up and using it for 20 minutes or so I noticed that sometimes while scrolling through settings, contacts and webpages, that when i am swiping over a horizontal band in the...
forum.xda-developers.com
Iheve tested it just for a couple hours but my issue happened when the phone was overworking itself and I have tried to force this issue for a while and nothing, the touchscreen is still working flawlessly, Ill try to update you all on if it worked or not
This problem is because this device is low budget and not for performance
I have replaced the broken screen of my Oneplus 8T (KB2003), where I have used a screen already attached to a new frame including the fingerprint sensor from AliExpress. The delivered screen with frame etc. looked exactly like the original one. This means I actually just had to switch over all parts inside the device. The phone is not rooted (never was) and still uses the stock recovery.
Now, everything works, except the fingerprint sensor. In Android 13 (Oxygen OS 13) the icon of the fingerprint appears on the screen, but the fingerprint is neither recognized nor there is a vibration. I already tried the following things:
delete all pins and fingerprints and reboot in Android 13
delete all pins and fingerprints in safe mode and reboot in Android 13
wipe all data (in the stock recovery)
factory reset
downgrade to Android 11 (via local install of the zip), here an error appears if I try to register a new fingerprint: "Error during fingerprint registration, please try again"
delete all pins and fingerprints and reboot in Android 11
delete all pins and fingerprints in safe mode and reboot in Android 11
Now the interesting part comes: If I boot the device with the old fingerprint sensor connected (Android 11 or 13), and switch to the new one while the phone is running, everything works. This means I can use the fingerprint of the new screen, register new fingers etc. with the new sensor. Once I reboot the phone, it does not work any longer.
Does anyone have an idea what I could try to be able to use the new fingerprint sensor even after a reboot? Thank you!

I suppose it's done for safety measures.
It seems there is some fingerprint sensor check validity is happening on boot.
If it's recognized as factory one, it works, if not it doesn't.
In your case you were just hotswapping sensors on running android, so the check doesn't detect it, but on boot, it detects non original one.
That would be a pity.
Yesterday I have removed the original fingerprint sensor from the broken display. I did some pictures:

Interestingly, also the small black part located between the actual sensor and the silver part at the cable (first picture) has a small transparent window in the screen.
Now I am considering removing my new screen from the repaired phone and try to exchange the fingerprint sensor. Actually, I wanted to avoid this and bought the display already attached to a (new) frame. At least it would be interesting whether there is an obvious difference between both sensors.

Thanks for information.
Keep us updated on this case.
I would use the msm tool as this would restore to original factory setting and write new partition data according to your hardware. This may register the new fingerprint sensor as authentic and would be calibrated during first boot. It's worth a try, I doubt it would work any other way. You can find msm tools all over xda! Good luck getting it to work!

delete all pins and fingerprints in safe mode and reboot in Android 11
Now the interesting part comes: If I boot the device with the old fingerprint sensor connected (Android 11 or 13), and switch to the new one while the phone is running, everything works. This means I can use the fingerprint of the new screen, register new fingers etc. with the new sensor. Once I reboot the phone, it does not work any longer.
Does anyone have an idea what I could try to be able to use the new fingerprint sensor even after a reboot? Thank you!
