FP4: Iode 7 status / Issue Tracker?

General Discussion
1

The Fairphone 4 has not yet received its update to Android 16 / Iode 7, which I understand, however is there somewhere some kind of issue tracker? What are the blockers?

I am asking mainly not because I want to receive the A16 update, but rather because FP4 ist still on Vendor Patch Level from September 2025, with the newer vendor releases only being merged in the v7-staging branch.

This is further a problem, since apparently since the September Vendor update, battery drain of the FP4 is abnormally high, with this problem being fixed with the A15 Fairphone vendor update (patch level October and later) see here. Currently, I need to charge my phone about 3 times a day, despite having a completely new battery installed… :confused:

Hey axo,

I don’t know the answers to your questions, but wanted to ask which version you are on now? I read that 6.12 is the latest stable version for FP4. Did you receive this?

Sorry for your big battery problem, hope, you will be able to fix that, soon.

Hi, yes I just updated to 6.12, but the vendor security level is still on September 2025 (Fairphone’s last A13 update, not yet Fairphone’s A15 update)

Okay, so then we need to wait for the experts :slight_smile:

I am asking for clarification in how to explain well, but as I understand all releases (including the ones from the manufacturer) have separate “Android Security Patch Levels” and “Vendor Security Patch Levels” and I am not sure if Fairphone do have a newer vendor patch level or not for the FP4 than the published September 2025 release? Another possibility is that that update will only come with Lineage 23.2, which is not yet incorporated in iodéOS.

Well, I would think that when Fairphone updates their ROM they not only pull in the security bullit ins from AOSP, but also the driver updates and therefor update the vendor level.

But even if that would not be the case, in the gitlab it is quite clear that the updates to “FP4.QREL.15.14.3” and “FP4.SREL.15.14.4” only happens on the v7-staging branch and not on the v6-staging.

See here for yourself: Repository graph · v7-staging · os / public / devices / fairphone / device_fairphone_FP4 · GitLab

Our developers reported that there are no Fairphone vendor patches for their Android 15 base since Sept 2025, so our 6.12 build has the latest available vendor security patches for the Android 15 base of iodéOS 6.x.

The bug of locked bootloaders not booting after updating to iodéOS 7.x on the FP4 have prevented us from releasing Android 16 based builds, so once that bug is resolved the upgrade to 7.x will happen (and thus the Android 16 vendor security patches will be incorporated).
