[Xperia X] Fingerprint sensor does not work [answered]
I updated to 2.2.0.29 EA yesterday, and was going to put fingerprint sensor to good use. However when I enter the wizard, the screen which asks me to read my fingerprint several times never respons to my attempts. In CSD tool the fingerprint sensor test also fails.
According to other users, it should just work. I did use it when I was still using Android on my device. Could the fact that it may contain previous fingerprints mess up the initialisation? What kind of logs would help pinning down the issue?
Thanks!
Edit: I have cleaned the sensor (power button) and my hands, no change. I have also tried it without protective cover on, no change. I also have another Xperia X with Android still installed, and I use its fingerprint reader daily, with cover on, so I know how it should work.
Edit: I got it working by flashing; see my own answer for details but it soon regressed back to the state of not working and failing the CSD test.
Edit: I flushed the fingerprint index and database, and it worked fine for a few hours again, until it broke by itself again.
Edit: I installed Sailfish 3.0.0.5 early today, and I could add exactly one fingerprint, unlock the device it with three times, and it stopped working again. CSD test for fingerprint reader couldn't register my fingerprint. Then I shut my Xperia X down and started it up, leading to the fingerprint I added earlier today being lost. The reboot deleted my fingerprint. So, the support seems as broken as iit was with SFOSX2.
Edit: I'm running 3.0.0.8 now, and magically my fingerprint reader seems to function correctly. I have been using it for a week now, and it's actually quite nice! Testing continues...
in my.case it would not even show an error.
put snd leave finger multiple times just had no effect

Sadly I think the Jolla developers have wasted time on a bling item. Their time would have been better spent getting the Bluetooth working properly or improving the functionality of the the various functions that need improving.
AlanBreen ( 2018-06-02 14:34:27 +0200 )editI think I met this bug but just in later phase; I wanted to add more fingerprints into the reader, and after the 5th one I started having problems with the reader. It stopped working completely (could not unlock with it anymore). After the restart it was working again, but it still does not register new fingerprints. At first the mapping failed immediately, and after selecting retry reader just does not register any touches anymore.
Also at this point CSD fingerprint test fails immediately with error

.It wouldn't surprise me the least if there were some undocumented "features" that are not publicly available in the AOSP version, hence rendering the whole fingerprint reader useless in the long run. Like, it doesn't accept as many different prints as the Android version. Let's hope this is not the case.
Direc ( 2018-06-05 16:30:57 +0200 )editI had problems registering my fingerprint as well. Finally found out that I had to double tap on the fingerprint reader and keep holding my finger on it on the second tap. It's as if I first had to activate the button by tapping before it could register the fingerprint.
