I'm having trouble with my phone screen when I'm on a call. The display turns off and won't turn on until a few seconds after the call ends. Home and power buttons do nothing while the call is active.

Did you install the sensor fix after flashing?

I didn't know about it. The website I got the install instructions from wasn't the greatest. I'm guessing just flash the one that says sensor fix http://forum.xda-developers.com/showthread.php?t=2488986 here?
Hi guys, I have a issue with proximity sensor, it happend from 4.4.2 and now i'm in 4.4.4 and still facing with it.
At the first time I think that is my app problem, so I don't care at all. But today, I found it (maybe to late) happend with all thing include call and the test in hidden menu.
This is the way how I made it:
1. cover the proximity sensor
2. start the call
-> screen go off
3. un-cover the proximity sensor
-> screen not turn on even the call ended. All thing you can do is press Power button twice
If this only happend with call, ok, I can accept it like a feature.
But when I try reproduce the issue in *#*#7378423#*#* - Service tests - Proximity Swich test, the result show that the proximity sensor cannotchange state and always "Detected".
So idk the problem is my phone or sony firmware, anyone can confirm that? I did some searching but can't find anything.
Thank you.
i think the problem is in proximity sensor because as u say it happend in 4.4.2 and 4.4.4, and i've use both firmware and i dont face any problem like that, and u can check if u have ur screen guard on ur proximity sensor, because it happens with me once i put my screen guard on proximity sensor thinking nothing will be wrong because screen guard is transparent but that my proximity sensor becomes like what u say, always detect, check it
It's not the problem of sensor, this problem is in firmware. I am facing the same problem and my frd too.

i never face this problem,
which kernel you are using, i am using vinays nitrogen kernel, does this problem occur on stock ?
Hi.
I have this wierd bug. When i call someone. Screen automatically goes off and wont come on until call is finished.
I know this isnt due to proximity. Even when the sensor is not covered up.
I am on stock mm rooted.
..
Does this mean my sensor isn't working or software issue?

Most likely your sensor is bad and always reporting NEAR, the symptoms you are describing are exactly what would happen in this condition... have you tried a sensor test app from the Play Store to see what the proximity sensor is doing?
Finally worked!!!! had to calibrate sensor
Well thanks i tested the sensor it was always showing 1cm reading.
Calibrated it using an app on playstore. >> Proximity Sensor Calibration <<
Now working fine.
Cheers!! :good::good:
I have a problem with the fingerprint sensor.. Since I switched to miui 11 with android 10 the sensor worked at times. It works for a day or two, then the menu disappears from the settings and i can no longer use it.
I try tu update vendor partition, wipe data, format data, reinstall new rom with all wipes, reinstall stock rom with Mi FlashTool, any solution works..When i wipe all, it works for a while and than, suddenly, doesn't work anymore!!
I have Mix 2S, i'm sure that is not an hardware problem..
Replace fingerprint sensor
I don't know why you say that you're sure that it's not a hardware problem, but to me, it sounds like the sensor is broken. I suffered this issue in my own Mi Mix 2s and it was caused because the "cable" of the sensor was folded (it's not really a cable, it's more like a flat plastic connector) and it worked one day and not the next. I finally decided to fix it by myself, looking for a youtube video about disassembling the phone and with these tools and the replacement sensor it was pretty easy (and quite cheap, frankly). I hope it helps!

I had the same problem. Mi mix 2s had a problematic/bad assembly line.
I have exactly the same issue. After Android 10 update the fingerprint sensor works for a while. After one day I recognized that the fingerprint sensor is not working anymore. And there are no options or settings in the system settings anymore. So I assume a software problem.

This problem is very boring!!! Have you try a solution, or a temporary fix???
No, I have no idea how to fix. Seems we have to wait till the next update from Xiaomi, which hopefully will fix the problem. It is really boring.

Your assumption is wrong... these options will not show up if the system can't find the fingerprint sensor... Had the same problem and it turned out to be a hardware fault, exactly like mentioned by Kaliotto. You can do a simple test via CIT (tap multiple times on kernel-version). You will find a fingerprint sensor check in there. If it does not find the sensor, it is broken, simple as that. Replacing the sensor is really no voodoo, did it in a timeframe of 30 minutes myself and it was really the first time I ever opened a smartphone. And the parts are really cheap.

I read on differents sites a lot of people who had problems with fingerprint sensor after upgrading to miui 11 with android 10..i don't think that all of us had hardware problem at the same time of the upgrading, it's very strange...
so, to avoid any doubt, i'm searching a new fingerprint sensor..the site suggested in the second posts seems to have problems with payment, any times i try to buy with paypal o credit card, the payment was refused..so i'm searching another reliable site..
I solved the problem. In my case it was defenitely a software bug. I tried to run the fingerprint test at CIT and the phone reminded me that the phone is protected by a PIN and can not enroll fingerprint information. So I switched of the PIN protection and the fingerprint test runs positive. Since that time, the fingerprint options in the setting was back again and I was able to setup the fingerprint sensor as usually.
So I thing the deactivation of PIN protection was the solution to get the fingerprint sensor working again.

So, you only disabled pin in the lockscreen (and set swipe method to unlock the phone)??
I tried now disabling pin and restarted the phone, but no options in the settings menu
Can you give me more details? Thanks
Update! After one day of use, I have to say, that the fingerprint sensor still does not work proper. After a while the fingerprint sensor stops working again. I played around with the settings, disabled the PIN protection and start the phone several times and than the fingerprint sensor was working again for a while. There is still something wrong. Also the CIT test sometimes pass and sometimes fail. Maybe it is hardware failure after all.
What I did: I disabled the password (PIN) protection, means no protection at all. After that I was able to run the fingerprint sensor test at CIT ( as cdfs wrote). This test was pass and the settings to configure the fingerprint sensor appears again in the system settings and the sensor worked for a while.
Since this procedure the function of the sensor is not consistent and I can not definitely say what to do to get it works. In the meantime I think that all the described workaround just works by accident.
NEWS: i changed stock kernel with two modded kernel (Twisted v22 && LawRun9.0_60hz) and fingerprint start to works again!!!
So, my idea was real: it's a software problem!!!!
Try it yourself and give me your feedback
Hi,
I had also the issue that the fingerprint sensor was not recognized. I replaced it.
Then the option was there again but it doesn't read any fingerprints.
The CIT test fails by the last step "Pixel open test"
Then I got a second new fingerprint sensor and replaced it again.
The test fails again in the last step!
These are the CIT messages:
Autotest: Testing
SPI test: Success
Reset pin test: Success
Interrupt pin test: Sucess
Pixel open test: FAIL
So I would say it is a Software Issue
Hello,
so I at the end found some users, having exactly that problem!
I bought a new sensor and changed it. Pixel Opem Test failed.
I bought another sensor with the same result: Pixel Open Test failed.
Is there a usefull solution?

Hello currently I am using mi note 9 pro but I am having fingerprint issue there is fingerprint option missing I am not able to mange fingerprints. Plz somebody help me
I have an issue on Samsung A515U
I already did factory data reset and upgraded to Android 11, nothing works.
I'm searching for firmware of Android 9 for this model and haven't found it yet.
Can anyone help me pls
Hello!
You can check the Samsung Fingerprint Sensor with Samsung Phone Code.
Just dial (like typing in a phone number) the Samsung Sensor Code: *#0*#
Then tap on Sensor, where you can check Samsung Accelerometer Sensor, Gyroscope Sensor, DL Magnetic Sensor, and Fingerprint Sensor.
In the Fingerprint section, Tap on “Normal Scan” and see which tests it passes and which one fails.
This is just an information, you can't repair or change anything.
Your plan to downgrade to an older android version is NOT a good idea.
They made very important changes (filesystem, security, framework structure....) in the newer versions. You might brick your phone and can't use it anymore.
To improve your fingerprint take a look at this postings Speed up fingerprint
Good luck!
Thanx for answering
I've already done what you mentioned and didn't work. I checked the sensor dialing that code and it seems to be good
Same issue here... did you get yours fixed yet?
same here, I do factory reset but no fix.
why this happen ?
solution: I went to a service store and they replace the sensor.
The test reports that the sensor is ok (all tests show as PASS), but I still get the "Fingerprint sensor calibration needed" message.
How can I calibrate the sensor? Where can I find the procedure?

Well this looks like a problem faced by most Samsung users after updating their phones. There is no exact way to fix this since Samsung is yet to release a fix to this issue.
But you can try this:
Change your lock, to swipe to unlock, which will delete your fingerprint data. Then set up your fingerprint lock again, rescanning your fingerprints like you did the first time you set your lock screen options.
I had/have the same issue after installing a backup of one A51 to another A51.
All runs fine, but the fingerprint.
Doing a factory reset -> fingerprint is OK and working.
Using the copy on the "wrong" phone -> fingerprint is NOT working
So it's no hardware issue, but I have not found a solution yet
Try to reflash the whole system with Odin and get the software from samfw
