Fingerprint Note 9

[boruciak]

Fingerprint on Samsung Note 9 does't work.
Accessibility service is ok - restarted.
Android 8.1.0
any idea?

possibly device feature? On my Motorola works only swipe left and right.

You're probably right. It does not work - the device's fault.
Left, right, up, down - everything is "dead"...
Tnx.

Trigger fingerprint also not working at me. Redmi Note 5 whyred, RR 6.2.0 Oreo 8.1. When in MIUI 9.5.17.0, I ever tried it, and didn't work too.

AFAIK, fingerprint when using it with screen on, should be requested manually. So it should be action. Autotools also have fingerprint action, but it puts it into input dialog category. The result is only true (fingerprint detected) or false (fingerprint wrong) and then timeout.

I suspect that it depends on the actual fingerprint hardware that's used by the device. Some sensors simply don't support detecting gestures I guess.
There were some hacky ways to detect a pseudo-swipe on some devices by detecting when a fingerprint scan did not succeed when the finger was placed on the sensor only for a very short amount of time but this did not allow to detect the direction of the "swipe".
There's also a new condition Biometric Authentication Dialog that works on Android 9 to check the fingerprint.

Hi Martin,

I've got a Note 9 with Android 9 & the biometric trigger works in a normal workflow.
But If I'm using this workflow as a widget the dialog box for biometric input does not appear?

Any suggestion? There is no error logged for the workflow...

[Desmanto]

Do you mean condition biometric Authentication dialog or trigger fingerprint gesture won't work? If your flow is triggered from widget, most likely it is the condition. Try to debug your flow and execute it manually inside the flow, check whether the condition is reached within the logic.

[Glatzi]

It is a condition and the biometric dialog just won't show.
I've created a sample flow. There is only the fingerprint condition and a screen notification for yes or no for debugging.

Until now I've worked with Tasker plugins but with Android P there is the option to use the fingerprint sensor natively.

Attached you can find the flow & the log. When the flow is executed standalone everything is fine.
Wenn the flow is executed through a widget it immediately returns false?!

I just tried your flow. Execute manually, working fine, the biometric dialog pop up and if I put my finger, it branches to true. Add a widget to home screen, action to execute that flow. It shows the dialog properly and branches to true if I put my finger. Same with widget show overlay. I am using Redmi Note 5, RR 7.0.0 Pie 9.0. But trigger fingerprint gesture is not working at my phone. Don't know if this matter.

It seems something is cancelling the dialog when you run it from widget.
