From a privacy point of view I would skip the fingerprint stuff completely and forget about it!

The charging stuff however...

That really needs to work reliably!
Hope you can fix it somehow

@nero355 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.

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

So if I had to choose (which luckily is not the case), I would always choose working fingerprint unlocking over offline charging. But either way it's not a big deal to me. I can do without both of these features.

@nero355 The problem with offline charging is that if you forget about it it might empty your battery and/or burn in the screen at the moment, so its more critical than fingerprint

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

So just like the buttons on my BQ phone are ignored under Ubuntu Touch I hope the Fingerprint Readers can be ignored on all Ubuntu Touch phones too!

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!

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

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?

A Former User

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

EXACTLY!

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

flohack

So seems FP reader can be fixed with a workaround

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!)
