FP5 - Random crashes to bootanimation & back to lockscreen

  • /e/ version: 1.18-t-20231207360613-stable-FP5
  • Device model(s): Fairphone 5 (bought from Murena)
  • Developer mode enabled: yes
  • Device rooted: I already had access to rooted adb. But I didn't modified the OS.
  • Trackers blocker enabled: yes

Summary

I experience random crashes. I can't see any specific pattern that may cause this behaviour.

The problem

Steps to reproduce

Just using the Fairphone 5. The crash can happen with any application (Browser, Files)

What is the current behavior?

The UI crashes. The Murena logo is shown, then I am asked to enter my schema to unlock the phone.

  • I checked the uptime: it is NOT a reboot.
  • I tried to use the fingerprint: I have to use the schema "first".

What is the expected correct behavior?

A reliable UI, without random crashes.

Technical informations

Relevant logs (adb logcat)

I can't get the logs, since it's random.

I tried to let adb logcat running on my computer when using the phone, but:

  • I didn't experienced the crash
  • adb logcat disconnect after few minutes (bug or feature ?)
  • applications like LogFox says that Android 13 Google has limited logcat access via ADB

Relevant screenshots

Screenshots are not relevant here.

Solutions

Workaround

None.

Possible fixes

I don't know.

But I am open to any practical way to find the root cause.
