the initial version of this bug report was created using Bugger 0.9.9+git3

I used the collect-logs.sh script from https://docs.sailfishos.org/Support/Help_Articles/Collecting_Logs/Collect_Basic_Logs/.

I collected the logs twice:
Once without using Android in the process of switching users.
Once with using Android in the process of switching users.

Then, I did search for vibra in both directories where I uncompressed the respective logs.

grep -Rin vibra /uncompressed_logs_path/*

Here are extracts of the very long outputs:

This appears only in broken vibra logs:

./prob_vibra/journal:356:Mar 21 06:46:42 XperiaXA2 alienaudioservice[7101]: [AlienAudioService] vibrator: Added default_alien
./prob_vibra/journal:1631:Mar 21 06:46:54 XperiaXA2 init: Control message: Could not find 'android.hardware.vibrator@1.3::IVibrator/default’ for ctl.interface_start from pid: 9 (/system/bin/hwservicemanager)
./prob_vibra/journal:2246:Mar 21 06:47:12 XperiaXA2 alienaudioservice[7101]: [AlienAudioService] vibrator: Hardware service manager has died.

My very basic understanding would be that Android cannot find/use something related to vibra, then “Hardware service manager has died”, then vibra isn’t usable anymore.

well, very basic understanding…
Any hints or other ways to explore?
Thanks
