[Samsung Galaxy S10/S10+/S10 5G/E Cross Device Deve] The A.I. Project:
Guys I am having some issues setting up the fingerprint. When I tap on "fingerprint" in the security menue the screen turns black and after some time I get an "app not responding" message. The top slider still responds and the "back" button is still shown. But only thing I can do to get rid of the black screen is kill the app. Note that this is not the bug mentioned in the known bugs for the fingerprint sensor (since that assumes one can even start the setup)...

I had a similar reaction during initial setup when trying to setup the google account and services. From online search there it looked like an issue from OpenGapps deleting WebView... I was able to circumvent (not fix) that part by completely deleting the setup wizard directory and just going with the basic LOS setup

The logcat does not really speak to me regarding what is going on.

I'm using the S10

I did a format + wipe + clean flash of

LOS 18.1, 2021-06-23 version

OpenGapps pico 2021-07-17

Firmware XXSBFUE6 as suggested

I ran Ivan's ROM a few days back (yes, I did a complete format after that), and with it the fingerprint sensor worked fine. At that point I think I had an even more recent firmware version though (I had updated to the most recent released with Samsung stock OTA), i.e. XXSBFUE6 was probably a downgrade.

Anybody else experiencing the "frozen black screen" issue, or anything else specific to fingerprint sensor setup?

Thanks in advance!

Edit: here is a bit of logcat that keeps repeating more or less the same, that looks suspicious:

The "failed to open part" looks like the issue

EDIIT: if this helps at all to break it down. The fingerprint sensor works fine with v1.4 (i.e. LOS 17.1) and with the current firmware it also works with Ivan's ROM. I also flashed the stock firmware in between, to make sure that any remainders of the "multi disabler" are gone. So it really seems to be specific to v 2 (I tried all 3 of them so far).

Any clues or help are warmly appreciated :)
