I installed the unofficial polaris builld 20200511 on my Mi Mix2s.
When done it booted smoothly into “e” and went through all the configs including the fingerprint.
However, after reboot the fingerprint hardware/setting is not there.
Also I am missig the “Face Unlock” feature. Is that usually implemented?
I’m surprised, my 2 Xiaomi devices (MiMix2 and Redmi4X) have full functional fingerprint reader !
16locke reports a functional fingerprint setup … Is the driver/software used during setup different ?
I’ll try a new build ASAP and carefully check logs about missing driver/software …
Good morning and thank you for your replies. @smu44: Yes I had tha latest version of MIUI installed.
Which version do you use? Finger unlock is a need thing and I do miss it.
On the other side … I can also live without it. @hervey186: Makes sense to not have face unlock under these circimstances.
Both my devices are running a build produced the same manner as yours, just a few days before or after.
And I don’t think it’s SoC related.
Very strange … As promised I’ll rebuild and check logs, probably next week-end.
Is it possible to have more details about what modifications you made (and how) please ? (I have no skill in debugging). In case somebody else wants to make an update for instance.
This device is officially supported by LineageOS on Pie so normally everything should work out of the box, no ?
palaychpolaris: Return oreo fingerprint
Tnx Google, now pie fingerprint failed cts, now it check yet date security patch. But old oreo prop pass normal without change security patch date. This reverts commit dca6244.
So they decided to use the Oreo FP software in Pie builds.
I just forked the LOS repo to my account, then added a commit for lineage_polaris.mk with LOS’s #dca6244 content.
Then used my account repo (android_device_xiaomi_polaris) for building.
@16locke reported to have FP reader working well with LOS16 and LOS17 but not /e/ Pie, even after reverting firmware with Pie MiUi.
I agree that, as it was working with LOS16, it should have worked also with /e/ Pie.
But the use of Oreo FP software in LOS16 was surprising to me, I thought it might be a possible cause of our problem.
If other users are willing to test and post back, they are very welcome
