Official or community build?
It does work for me on FP4 eOS v3.1.1 and it didnāt before this update. I use the official build.
Official
But realised itās because the bootloader is not locked.
Fairphone
switch from /e/OS official T (A13) to /e/OS community A15 in one go. Details below.
Not the recommended way
Starting point:
- FP3 on e-3.0.4-t-20250709507786-official-FP3
- Bootloader status: locked
- Use developer options: activated
- OEM unlocking: activated
- USB debugging: activated
- no change attempted to bootloader status
Attempts of local updating
- Local update to e-3.1.1-a15-20250830521751-community-FP3: failed
- Local update to e-3.1.1-a14-20250901522231-community-FP3: failed
Attempt of ADB Sideload via /e/ recovery 3.0.4

Step 1/2
Step 2/2Install completed with status 0.
In the course of the process right above, I had to respond āYesā to the message:
Signature verification failed ā Install anyway?
Booting into system from /e/ recovery 3.0.4 succeeds.
Finishing line:
- FP3 on e-3.1.1-a15-20250830521751-community-FP3
- Bootloader status: locked

- Use developer options: activated
- OEM unlocking: activated
- USB debugging: activated
Final observations and comments
- I did encounter a bootloop after the first boot into the new system and first reboot, but upon later boots, this has not (yet) occured again. I might have entered recovery and bootloader (no change attempted) again in the meantime, but do not remember the exact succession anymore.
- The (regular) reboot takes a relatively long time (40 seconds) on this FP3 now (appears dead for a while until it āwakes upā again), on my daily driver FP3+ it takes roughly 22 seconds.
- If you want to do the same operation at your own risk, make sure to download

Hello,
an idea when A15-official for Fairphone 4 will be available ? A15 is only available for community edition on Fairphone 4.
Thanks.
All that is known (for quite some time now):
Device: DRE
e/os: 3.1.1-a14-20250831522231-community-dre
No A15.
Issues:
- Take screenshot action missing in App Drawer when in 90Āŗ degree view.
- Kill foreground app missing from long press action
- stock camera app - unreadable text when taking close range pictures
- No incoming SMS texts.
All issues carried over since e/os 2.0

No problem to update to 3.1.1. But, I still have this problem: I have to hide my IP address to be able to connect to the internet (4G/5G mode). I canāt set my IP address to exposed, otherwise I wonāt have an internet connection. Well before 3.0, I didnāt have this kind of problem. Whether with hidden or exposed IP, I had access to the internet. If I disable Advanced Privacy, I will no longer be able to block trackers or hide my location. In this case, how can I solve my problem?
Thank you.

Update went smooth. No special issues. I am waiting for A15 and hope that Miracast / WiDi will work again (as it did with A13).
The camera takes 48MP pictures again!
A big thank to the team!
@Aln: my WiFi and mobile data are working as expected. IP hiding works as well. Maybe you have some odd settings? E.g. privileges?
Hello all,
On Gauguin phones (MI 10T Lite 5G), has anyone tested the local installation of 3.1.1-A15 from 3.0.4-A13?

Thank you.
I have checked in Settings / Update : no update available for me for FP6 Official.
USB-C wired audio now works as expected on the CMF Phone 1
Itās still not working for me.
Iām on: 3.1.1-a14-20250831522230-community-tetris
Me neither. Why does some people seam to have the OTA ?
FP6, preloaded when bought, no new update here yet. Hoping thisāll come through soon, my guess is itās being done in stages.
Per this, you can see community for FP6 is at 3.1.1 but official is still at 3.0.4. Iām guessing the official build just isnāt ready yet for FP6 and thatās why weāre not seeing the OTA yet.
Some of us already did the manual install of the A15 3.0.4 which does have OTA, but requires that manual install before.

Did an dirty update to the community Build. Worked fine device boots and files are still there. Was missing some apps tho (molly, syncthing-fork and some more, all apps from f droid or just downloaded apk) all other apps from app lounge where there.
Apps are where also only no icon on the launcher, when searched manual I could open the apps.
To get them show on the launcher again I did unistall the apps and reinstalled them.
All good so far. Loving my e/os Tablet ![]()
