[WalterZwei]

Version

2.2.2

Source

Google Play

Vault encryption

Yes (with biometric unlock)

Device

BQ Aquaris X Pro

Android version

LineageOS 20 ( = Android 13), with Google Apps/Services

ROM

LineageOS 20 ( = Android 13), with Google Apps/Services

Steps to reproduce

1. Open App
2. On the login screen the biometric button appears
3. I press the fingerprint sensor
4. The button changes immediately to a green checkmark and vanish after ca. 0.3 seconds
5. --> for about 3.5 seconds, only the lockscreen is visible (the screen with username and password), nothing else happens <---
6. after those 3.5 seconds without further interactions, the lockscreen vanished and the code screen appears

What do you expect to happen?

the code screen has to appear without delay after step 4

Remark: On a Nokia 8.3 (Android 12) the delay is shorter, approx. 0.5 seconds

What happens instead?

a 3.5 second delay, see step 5

Could you capture a log using ADB of you reproducing the issue and share it here?

Sounds like this may be similar to: #1183. If it is, I'm afraid there isn't much we can do on our end to improve performance here. We can show a "loading" dialog instead of freezing the UI, but you'll probably still be stuck waiting for a few seconds.

Thanks for the quick answer.

I'll try to log it, but it may take me a while to upload this

It see it as a minor bug, only a little annoyance on my spare phone from 2017, so please do not spend to much time on this issue.

Closing as a duplicate of #1183 since this sounds very similar and we haven't gotten any new information.
