FairPhone 5 : Loss of fingerprint function

Hello,

I’ve been using /e/OS murena for a few months without any difficulty and last night I lost the fingerprint function without any explanation (no phone dropped, no application installed when the function was lost). I don’t know if the hardware function is broken or if it’s software. I’m thinking of reinstalling the OS to find out, but I’d like your opinion.

The only potentially impactful thing I did was: I remember that 2 days ago I updated a new version of “Murena MDM” system app (foundation.e.mdm) to version 6.03. I don’t real known what it does but after the installation there was no problem. I don’t know how to rollback this update to check.

The function has totally disappeared from the system settings menu, it’s no longer offered anywhere.

Thank for your help.

You could go into Settings->apps->all apps then 3 dot
righttop corner to see system there you should be able to find the app and you could delete the storge. Disabling or uninstalling it not possible

Hello,

Thank for the idea.
I deleted the storage of this app but it does not fix my issue.

You did that to MDM right?

It should also be possible to do it with the system app which holds the fingerprint :thinking::thinking: Just throwing in ideas, not sure how valid it is.

Yes I did it on “Murena MDM”.
But I don’t know the name of the system application that manages fingerprints :slight_smile:

Perhaps my issue have somthing to do with this issue :

But /e/OS does not have the “Find Device” feature so I cannot try this workaround.

I reinstall the image IMG-e-2.8-t-20250219470165-official-FP5.zip from /e/OS official FP5 download but it does not fix the issue.
Perhaps I got a hardware issue but I don’t really believe it.

It is possible, that you have.

Maybe skim this feedback of 2.8, if others reported:
