Hi to all.
I don't if it's due to ota update, but after ota update, i have many problems with fingerprint sensor.
The sensor often doesn't work, that means that doesn't recognize that i'm touching the sensor.
Before the ota update, sometimes it recognize the wrong fingerprint, but now it seems like the sensor is off.
And if i try to reset my fingerprint, deleting all and adding a new one, i must try many times only to ave a respons edurign the new fingerprint registration.
Any idea or solution about this problem?
Thanks.

I noticed same fingerprint issue after ota update.
Setting finger scan is very slow and have to repeat positioning finger to start new scan.
Have to press repeatedly before anything happens.

After OTA update fingerprint sensor has become, fail, then he works on unlocking when the phone is. You raise it to unlock it and he says in response to too many attempts. Either you put a finger on the sensor, he quickly starts to vibrate a few times and, again, he says that does not recognize and remove too many attempts! ?? What's the matter???
And return the function menu Application Lock.

Fingerprint problems began already with the test OTA upgrade Oct/19. Since I used it only for short, I thught it was just my subjective feeling. Now, apparently, the others have also similar observations with the official OTA Oct/24.

The strange thing is that if the metal is connected to charger,  the fingerprint sensor work fine. But if i disconnect the power cable it stop to work.

It works same fine (or same bad, about 20% of cases working, rest not scanning at all, or fingerprint not recognized) on charger and disconnected and before and after OTA.
You can try to make factory reset and see, if if works better then.

I was able to test fingerprint scanner with the apps :
https://play.google.com/store/apps/details?id=hibernate.v2.testyourandroid
https://play.google.com/store/apps/details?id=com.rhkr8521.fingerprinttest

BTW: the worst side is Wi-Fi, it has very limited range and speed, compared to my previous phones.
