I don't see how the option, to use your fingerprint for unlocking, affects privacy negatively. After all, you can use it or not, it's a choice.

It should not have existed at all, but I guess the big corp companies wanted our fingerprints too ?!

That is an opinion, and you get to have that opinion, but it does not explain how the option affects privacy negatively.

And I frankly don't see what's so important about offline charging either.

Really ?!

It's a huge part of having a reliable phone/a phone you can count on!

How so? I have never used it... well, not by choice anyway. If my phone switches on when I'm charging it, that is fine.

Really !!

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

Come on...

It's basic functionality in case you run out of battery at some point!

How it should work :

Phoned turned itself off.
You plug in the adapter.
Phone boots to Offline Charging Mode
You see some kind of indicator that it's charging. Usually a large battery and sometimes a cable attached to it.
The screen turns off after 15 or 30 seconds or so and the phone keeps charging untill it's full.
During this period the Notification LED can sometimes light up as Red/Orange/Green depending on the status of the charging process.

THAT's HOW ALL PHONES WORK!!!
So we need it to work. No discussion possible!

Yes. I don't see a problem there. I trust the UT folks not to send that fingerprint anywhere else.

Okay. I don't need it. ¯\_ (ツ) _/¯
Discussion is always possible, by the way, but I think we're done here. A bit too much drama and all-caps shouting for my liking.

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.

@nero355 I would say without discussion nothing is possible. Also smiley, winking faces, hopefully hinting at humour or irony do not always convay that.

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 ?!

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

Moem

@flohack said in Known Issues:

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.
