Yeah dont want to ride the horse until its dead but:

Fingerprint sensor is a fully closed-source implementation, so UT does in fact not store any fingerprint but the Android container does this by itself

Normally the prints go into the TEE part of the phone (Trusted execution environment) and cannot leave it again - I trust Androids and the hardware manufacturers design here that fingerprint data is one-way

Instead the reader sends the print to be authenticated again into that secure environment and just gets back if its ok or not.

The stuff you are describing sounds like the awfull TCPA/Palladium made Fritz Chip or widely better known as the TPM Chip : Am I right here or not ?!

Ubuntu Touch is about PRIVACY and you want A COPY OF YOUR FINGERPRINT stored on your phone ?!

What's the difference between storing a fingerprint and storing a password?

@cliffcoggin You cannot change your fingerprint, but you can change your password if needed.

Offline charging now fixed in a way that its safe to use

flohack

So seems FP reader can be fixed with a workaround :pen:

flohack

Fingerprint sensor workaround is committed and should be in the image in 1-2 days...

Verrrry nice! Is that workaround something that might also be appliccable for other devices that have a fingerprint sensor?

flohack

@moem yes indeed. It helps only though for the siuation that registering/enrolling fingerprint works, but the lock method cannot be selected. That affects at least also the Nexus 6P but there we need to upgrade to Halium 9 first

Fingerprint works good for me (Oneplus 5T).
I m on Version 24 (Release-Kandidat 2022-W04).
Thx for your work!

Moem

@topse-0 Oh man, I just had to try it. It works just fine! So cool!

@Flohack Are there still problems with RC, or is this version safe? I can switch back if need be... (But it's just so cool!)

flohack

No RC is fine if note app does not crash
we release another RC today so then should be all good

It won't, because I don't use it.
... Man! Fingerprint unlocking! So cool! ️

flohack

@moem Its cool but its not very reliable: Lomiri punishes a "bad read" or "partial fingerprint" message from the container with letting you enter the PIN only
And before a PIN has been received you cannot do any FP unock anymore.

Yes works very much when it feels like it. Nice suprise when it does though.

I don't care. If I don't like it, I can disable it. For now, I love it to bits.

Lakotaubp

@moem Reverts back to four digit pin anyway so your never quit sure which one you will get

Moem

@lakotaubp It seems pretty reliable for me... maybe you guys just have weird fingers!

Lakotaubp

@moem The fingers are fine. It's the prints I can't quite fake accurately yet

sorry for restoring this old thread.
After successfully flashing UT without using TWRP and on top of android 10.0.1 everything works fine, but I have no wifi.
Networks are detected, it shows: connected, but there is no sign in the indicator, and no ip-adress shown. is this a known issue?
I already switched to rc-channel, but no change.
