FP4 Quickstep keeps stopping after A15 upgrade -

[Paul_Elsner]

Since I’m so annoyed by Fairphone not fixing the issue I finally collected some crash logs.

I freshly reseted the quickstep app.To reproduce the crash I just need to swipe up to open the menu, swipe down to close it and crash.

And I’m not an Orange customer.

I dont think this workaround is for the “non tech savvy user”, so I will not mark this as solution, however I can link it in my post that is marked as " solution" , so both options are visible.

Still no official response from fairphone, despite multiple reports of problems following the installation of android 15. A group action has already been envisaged, as exists for consumer associations for other consumer goods (cars for example).
I imagine that what we read here is only a small part of what owners of fairphone may encounter, because not everyone is aware of this forum, and the responses via official communication channels are quite silent.

Android 15 is Now Rolling Out to Fairphone 4! (FP4.QREL.15.14.3.20250923)

Dear Fairphone 4 Community, We have received your reports regarding issues experienced since the Android 15 rollout. Thank you for sharing this feedback promptly. We want to confirm that the reported issues have been passed on to the relevant teams and they are actively working on fixes. You can expect to see issues resolved in the coming software updates. As soon as a new software version is available I’ll post the release notes here on the Forum! Best, Lotte (Fairphone Community Manager…

Beside the fact that Orange FR and BE user should not have received/did not receive the update and received another Android 13 update instead.

So compared to the group that could have been affected when no actions woould have been taken by FP, I think the group hit is rather small.

And while I understand the issue is annoying, installing another launcher as workaround is rather easy in my eyes.

[Paul_Elsner]

Using a different launcher is like using a different phone.

Icon/app placement on the screen(s) is very important for intuitive phone usage. I tried the proposed launcher, but it was super slow and I had to rearrange my apps, or learn new usage patterns.

So please no excuses. Especially since it seems the exact same bug was already present on FP5 updates.
