Try rebooting ure phone
This was happening to me on the older version of the motorola software. Since I updated to 1.5.x I have not had this issue. A simple reboot always fixed it for me in the past.
Yesterday I was upgrade to 2.3stock ROM.
After that I try to setup finger scan, but finger print sensor doesn't work.
It didn't scan my finger print.
How I fix this problem?
Thanks

I had this issue, i just have to restart whenever it happens.. thats why you input a code, right ?
I already it but it still can't scan l.
I didn't like unlock code.
Because I drive a car very fast, I didn't have time to look at screen.

You probably need to wipe your cache's and stuff. Something is borked and that should clear it out.
I voided my warranty.
After I updated to Gingerbread I couldn't get the fingerprint scanner to work. A week later it just started working. Not sure what the problem was.
Atrix 4G
I have the same problem .... Anyone know anything?
I had the same problem, no matter now many times I rebooted, the fingerprint scanner doesn't register any swipe at all. I did a battery pull and the fingerprint scanner started scanning again. Weird, hope it works for other? If not factory reset would also be something to try.
Hey guys,
I know this thread already exists in this forum but has come to an end with no solution and since its kinda very important to sort this issue to be able to use my phone I thought ill start fresh for some input from the experts.
I have a Galaxy S2 I9100 rooted with a custom ROM(slim ICS 4.1 when the issue started) and it started randomly freezing when unlocking the screen and normal use .but since last week it wouldnt let me make or receive calls as the phone freezes and reboots 10-20 secs into the call..i updated to 4.2 with the hope of resolving this but tht didnt work..I have changed kernels and ROMS(resurrection, cm9 release build)..though the dialer did work for calls on resurrection ROM the proxomity sensor wouldnt work..
so i tried going back to stock sammy ICS (XXLPH) and then the dialer would work but again without the proximity sensor and the samsung tests also confirmed that the sensor wasnt registering...
am rooted now and back to slim 4.2(dont like the look of sammy) with siyah kernel 3.2.2...the dialer and proximity sensor don work..the rest of it is all fine..
Ive done all the wipes each time ive installed a new ROM...also done kernel wipes before installing Kernels..
I think its not a ROM/hardware problem but well it could be but hope to get it sorted through the normal techniques..I cant return my phone for repairs as it was in mint condition bot second hand in UK without warranty papers..
Any help would be highly appreciated..thanks
EDIT: It seems the proximity sensor is to blame for this problem as i found out through other posts..and also i can make and receive calls with the headset/headphones plugged (in which case i assume the phone doesnt try to activate the proximity sensor)..
For now i would like to know how to disable the proximity sensor on the phone..I have tried inserting the gsm.proximity.enable=false in the build.prop editor using the ROM Toolbox lite app n rebooted...but that din seem to work...is there any other way to do this??pls help
I am having EXACTLY the same issue as reported here and it's driving me mad. Did you ever find a fix for it?

I havent managed to find a solution as yet..it seems the proximity sensor and the screen brightness sensor(which are on the same PCB i think as per the unassembling video) have a hardware fault and might need repairing..
Some kernels i think maybe bypass using the proximity sensor if its not working..for now I am back to the SLIM 3.2 ICS rom..It doesnt switch off my screen on call and also no auto brightness adjustment but rest all works ok so am using it for now before i get the hardware repaired..
also the resurrection rom v 2.5.1 works fine in the same manner(havent tested many others..CM7 release build doesnt work)..or you can try that script in build.prop to disable the proximity sensor..
check how it goes..
How about CM9? Do these problems disappear on CM9? CM9 was working well for me but the home key and lock screen never worked. I applied all the common fixes to the keystr file but it never made a difference so I switched to slimics which worked. Then I discovered these annoying call screen off and waking problems :/

I tried checking with the testers for the Slim ROMS..regarding differences in kernel or anything for slim 3.2 and 4.2(3.2 works while 4.2 doesnt) but they couldn't tell me what was the exact problem or the differences that should affect in this case..I haven't tried a CM9 ROM yet but it could work..The kernel for the resurrection ROM is siyah kernel but when i tried that kernel with the slim 4.2 ROM that still didn't work for calls as the phone rebooted.
Have you managed to find a replacement cost for the proximity sensor? also does your screen brightness sensor work?
Hi All
Any one facing proximity issues here , i saw so many peoples reported in mi forums that when we make a call screen blacks out when we moved to ears( Thats normal) and won't turn back again , so i have to wait the other side person to hangup the call or screen won't turn on power button does work that time, i think this only affects with Sensortek stk3x1x sensor, Redmi note 3 pro comes with two proximity sensors one is from Liteon and other is Sensortek.... Liteon sensors doesn't have this issue, for temporary fix "Wipe proximity area with a cloth or reboot fixes this and it comes back after sometime....( Calibrated but same it works for sometime) no idea wats causing this , issues there in Miui and CM roms....
I found sometimes a flip case with a magnet can cause issues like this when folded right back against the back of the phone, the screen won't come back on because it thinks the flip case is closed.

yeah but i don't have flipcase, this sensor issues starts with those have "Sensortek Proximity Sensor" Liteon doesn't have issue i think....
Flash the rom again using mi flash tool u will find that yr issue will be solved
Or go to test mode amd calibrate the sensor... that's all
Fastboot flash persist persist.img from latest miui rom? I recently had a problem with sensors. The above cured all
@Hemphiz i think that method for dead sensors bro, this one working sometimes it doesn't mostly if we flash a new rom and use no issues but if we reboot the phone after sometime issue starts.... @ra.one i did that bro flashmiui and recalibrate sensor but that works for temporary please check which sensors you got from this app from playstore https://play.google.com/store/apps/details?id=imoblife.androidsensorbox
if you got Liteon Sensors mostly no issues with proximity, if u got Sensortek u will be having issues or once u got issue it will come back..... im not sure why is causing that..... this is really very annoying bug.... Thousands of people reported in Mi forums about these proximity issues on various devices even on newly launched Redmi 3s/ prime may be they have all got "Sensortek Proximity Sensors".......
This is not a bug, You can disable Prevent Pocket dials under Settings-->Lock screen-->Prevent pocket dials...
I had this since last miui 6.9.9 flash.
Disabled prevent Pocket dials and All is working fine
Edit: for a few hours it was working.
Now its the same again. Phone blacked Out After a call and wont turn on, After a few seconds its coming back. As i said , since flashing new 6.9.9

like i said it may be mostly an issue with Sensortek proximity, can u check which sensors u got from this app https://play.google.com/store/apps/d...droidsensorbox
I have sensortec.
But i think its Software related.
Its since last Update.
I calibrate the Sensor and the issue with calls is still there.
Sensor Works fine, test is okay.

Yes i think its software related but, one trick works clean flash the same rom and use it for a week without any reboot...... (DO CLEAN FLASH and Dont reboot the phone)
don't need to calibrate.... for me when i install new rom and use it for a week no issues , if i reboot the phone the issue starts after sometimes.... i don't knw wats causing it so many peoples with sensortek having issues and this bug is not resolved from Miui 7 to Now Miui 8 MM, the issue there in Custom roms im using RR rom i have issues....
Guys For those having issues Check which sensor you got from this app, if u have proximity issues while calling its mostly "Sensortek"

We need Permanent fix....
I also have exact same issue and i have sensortek sensor. But i can unlock the screen while on a call by pressing power button and then unlocking with fingerprint. Bit annoying

So its confirmed its an issue with Sensortek Sensor, no Liteon users reported here, like i told flash the same rom which you are in (clean flash) and don't reboot phone for a week there will be no issues it works perfectly, if u reboot a phone once the issue starts again after sometime so after reboot something is going on no idea what....
i am using this app(for rooted users) on official RR and it works fine

even me used, but i don't think its properly working..... this issue starts only after a reboot, when u flash new roms and after boot dont reboot or power off the phone for a week, not needed any apps, proximity will work properly but once u rebooted issue starts....
But this app's settings load every time phone boots up.so it will work after every boot.
press thanks if I helped u in any way

yes this app i tested earlier, but after sometimes may be in a day or two it won't work....
Found another related issue with proximity , i think proximity is not working properly when there is not enough light around us something related with ambient light sensor i think ..... Eg: if we are in a dark room proximity won't work correctly turn on the light and try it works properly.... i think Xiaomi messed up with something with both sensors Liteon and Sensortek thats why Liteon users face Gyroscope lag in games in dark room and now i think may be the same reason why proximity not working properly in dark room....
hello. I have the BUG but my phone has sensortek version 1 (not 2)
When in a call the screen wont turn off when placing the phone at my ears. With whatsapp the bug wont happend.
I think this is a BUG related to sensor + phone app
A functional workarround is to dial, then press menu (putting the call at background) and then putting the call at foreground again. It works 100% of the time.
Any news? I have this annoying problem too!
Hi!
My phone has problem with CM13, so I tried many roms and so on.
Finally I knew that,
If I flash Radon-V2.8 with choosing FPC, Camera works but Fingerprint scanner die.
If I flash Radon-V2.8 with choosing Goodix, Fingerprint scanner works but Camera die.
Now I use cm-13.0-20160902-UNOFFICIAL-kenzo.zip and be in such situation.
Is there someone in same situation? and how can I solve this problem:crying:?
