Initial builds are currently compiling and will be most likely available in the next 24 hours.
[Fairphone 4] srdempster:
Thanks for the hard work in bringing over to our phone! I will be installing and testing. I hope that it will eventually be able to fully relock the bootloader so we all can use Google Wallet. I would also volunteer as a beta tester if you need it.
[Fairphone 4] srdempster:
If you're not already aware the link to the builds page for FP4 is showing an Internal Server Error
[Fairphone 4] Sony make.believe:
He is aware and posted a information in his 2. post:

"Initial builds are currently compiling and will be most likely available in the next 24 hours."
[Fairphone 4] srdempster:
Maybe I'm just being impatient 😂 but when it was announced the page was missing and now it's showing the error. I'll wait a bit longer 🤭
[Fairphone 4] mikeioannina:
There are some issues with the download portal, you can get the build directly from one of the mirrors: https://mirror.math.princeton.edu/pub/lineageos/full/FP4/

Does the wideangle camera work in Lineage OS? Does the 48 MP-Resolution work?

Is Volte and VoWIFI ok?
[Fairphone 4] srdempster:
My only question is that dual SIM support is working aka eSim please?
[Fairphone 4] NadCat_:
Is the boot.img the one we can use for rooting?
[Fairphone 4] srdempster:
Yeah that's what you drag into Magisk to patch
[Fairphone 4] Powdery:
Just installed on my FP4. Everything went smooth without any issues. Installed with MindTheGapps.

This is working for me. Setup is SIM1 is physical and SIM2 is eSIM.

Wideangle camera works, although I do not have anything to compare quality with.

There is a bug in Aperture camera app on FP4 where the app will stop responding after you click one of the thee photo modes (wide angle, normal and ??). But you can just close the Aperture camera app and start it again. Will investigate further.

VoWiFi works. Did not have a change yet to test VoLTE.

@mikeioannina, thank you for the build!
[Fairphone 4] Hoppråtta:
Only issue I found up to now is in the camera app, when switching camera it freezes the app. Switching cameras works in open camera.
[Fairphone 4] srdempster:
Took the plunge and have Lineage installed on my FP4 now. Thanks again to the OP for getting the rom to the official stage. It went very well and was pleasantly surprised that my eSIM remained stored in memory. Considering it has had a full format and re-flash. I am currently installing all my apps and have checked in fastboot if i can relock my bootloader by running get_unlock_ability and getting a one. By that understanding i can safely lock it but didnt know if lineage had a signed key to enable this.
[Fairphone 4] kekerosberg:
New FP user here. Thanks for the ROM @mikeioannina !

There is an issue with binding the home button long press. I am able to assign a function for the long press from the settings, but nothing happens from the long press. Long press for other buttons works fine.
[Fairphone 4] mikeioannina:
As far as I know official builds do not support relocking, I am not sure if it's set up properly so I would not advise relocking

I will look into that
[Fairphone 4] Hoppråtta:
I think it sees the tof sensor as an Camara and freezes the 2 other ones
[Fairphone 4] srdempster:
On the camera yes there is a bug. If you select 0.7 you get the ultra wide and 1x the standard it works OK. If you select the far right one you get a blank screen. If you close the camera app completely and go back in the first two work but the third still crashes
[Fairphone 4] mikeioannina:
Looks like camera is a mistake on my part, 3rd lens shouldn't show up in the picker as it's not usable by normal apps.
[Fairphone 4] mikeioannina:
Next build will have the 3rd lens removed from Aperture and 60fps recording enabled for the back main camera up to 1080p resolution video.
[Fairphone 4] Hoppråtta:
Awesome, do you have any recommendations for a working logs app? i just get a spinning circle after first run.
[Fairphone 4] Hoppråtta:
After using it for a while, i feel like the wifi connection is a lot weaker. I get poor reception and disconnects where on fpos i never had a issue.

i exually caused it myself when i needed 2.4ghz wifi for an update and changing back to 5ghz on the router i changed the channel, that one was unstable. now back on 116 it works great. sorry for the wrong report.
[Fairphone 4] j0110:
Hey !

Thanks a lot for your port !

Before installing it, can anyone tell me if adoptable storage is working fine ?

Thanks a lot !
[Fairphone 4] srdempster:
Yes it works fine with no issues this is not a beta it's a fully fledged OS
[Fairphone 4] j0110:
Perfect ! Thanks !

I was fearing it would not work because on other LOS devices, adoptable storage is broken.
[Fairphone 4] NadCat_:
Not sure why but since using the official build I can no longer transfer files between the phone and my computer. It still gets recognized (for example in ADB) and when I set it to picture transfer it pops up in Windows Explorer but file transfer doesn't do anything (dev options are enabled and USB is set to file transfer). I already tried different cables and ports but before switching OS they all worked fine and I doubt all of my cables and ports randomly broke the moment I switched
[Fairphone 4] srdempster:
I've not tried transferring files yet but I would try toggling off usb debugging see if it helps.
[Fairphone 4] NadCat_:
Can't believe the answer is that simple. This works, thank you!
[Fairphone 4] srdempster:
Working as an IT Engineer I've learnt the hard way that the simplest and daftest ideas often work. I spent 7 hours trying to boot a problem VM Server only for my colleague to come and tweak the RAM settings for it to work 😭
[Fairphone 4] Hoppråtta:
The wallpaper app has some bugs i think, as the preview window above the color picker never changes, it gets a storage permission denied error. had to turn the photos and videos permission on and off a couple times on the wallpapers and styles app for it "stick". so the permission box when you first have to give the permission doesnt always work.

to reproduce

clear the storage and cache for wallpapers and styles

open the app

give permission in the box

change wallpaper

open app again

you expect the new wallpaper to show but shows the tuquiose one untill i click on don't allow and than allow in the photos and videos permission for the app
[Fairphone 4] srdempster:
I've not tried the colour picker but to add to it you can't add live wallpapers to the lockscreen in it. It appears to work but doesn't change it.You can only add on device wallpapers.
[Fairphone 4] Hoppråtta:
The color picker works if I do ⬆️, issue was that the permissions you have to give when first opening the app don't work the first time. And than you get an storage error in the logs that make it so the preview window above the colors picker never changes wallpaper, no matter what wallpaper is set. And the color picker seems to use that preview window to change the colors.
[Fairphone 4] minecrimex:
Hi !

First of all: Very fast, stable and efficient ROM, far better than stock !

Now to my problem:

I unlocked my bootloader and installed the 20230115-build. After that I wanted to immediately flash the "MindTheGapps-13.0.0-arm64-20221025_100653"-GApps package. This failed due to not recognizing the installed Android Version. After that I booted successfully into LOS and rebootet directly into recovery again to factory reset and flash the GApps-Package again, which worked just fine this time.

Now I wanted to re-lock the bootloader to get Google-Wallet and some other Apps to work and pass Safety-Net in general. But sadly I was not able to lock the Bootloader and boot into plain LOS or LOS + GApps anymore. Only solution for me was to unlock the Bootloader again...

I would really appreciate your help to get this setup + locked Bootloader to work and use it as my daily driver ! :)

Thanks in advance.
[Fairphone 4] Hoppråtta:
Wallet works with magisk hide props, safety net fix and hide list
[Fairphone 4] minecrimex:
Thank you for your fast reply ! Originally I intended not to use Magisk and/or root my phone (I like to be as simplistic as possible when it comes to my daily driver). A locked bootloader can be quite important for physical security so I really would like to lock my Bootloader with LOS + GApps. If anyone knows how to achieve this setup I would be rather thankful ! :)
[Fairphone 4] minecrimex:
I tried to install Magisk with the newest LOS 20 for FP4 but after reboot WiFi was not working, no calls, no sound. I extracted the boot.img from the LOS.zip, patched it on-device with Magisk, booted with that img and installed it permanently through the MagiskManager (Recommended option).

What did I wrong ? Does anyone have the same problem ?
[Fairphone 4] Hoppråtta:
I followed this XDA guide and it worked great
[Fairphone 4] srdempster:
Need to ask a bit of advice. Which version of magisk do you use and which is the best site? I made the mistake of dabbling with Ubuntu Touch and now some of my sensors have stopped working. I lost proximity and rotate. See this link in the FP forums about it https://forum.fairphone.com/t/solve...er-installing-experimental-image-ubuntu/87942
[Fairphone 4] minecrimex:
Thanks man ! Its working ! I used the Magisk-App to persist the patched boot partition, that seems to be the reason why it didn't worked. Directly flashing it with "fastboot flash boot" did the trick.
[Fairphone 4] srdempster:
All working fine now as read the guide just gonna find the modules now
[Fairphone 4] minecrimex:
What device Fingerprint were you using ?
[Fairphone 4] Hoppråtta:
Fp3. in the new beta version of props it only sometimes worked, the older 6.xx works great
[Fairphone 4] minecrimex:
Is here anyone who successfully flashed LineageOS 20 + GApps and locked the Bootloader (Standard + Critical) afterwards without causing a bootloop of LOS ?
[Fairphone 4] Haldi4803:
Is battery life any better on LOS compared to Stock?

Loosing 2.5% per Hours on Stock rom. Just in Doze mode... no matter wheter in WiFi, Mobile or Flight mode.
[Fairphone 4] martinsche:
Hello, is it possible to compensate the ghost touches by software?

I imagine, that it could be possible to ignorate screen touches, when they occur much too fast. The other possibility is to reduce the sensitivity of the touchscreen. What's your opinion?
[Fairphone 4] minecrimex:
For me, it got massively better, even with GApps.
[Fairphone 4] MAMeingast:
@mikeioannina Thanks a bunch for this ROM - I've been using it for a while now and it's great! I've only run into one issue: When using VoLTE, I don't hear any ringtone. It's just completely silent until the other person picks up. Is this fixed in one of the newer nightlies? What is the easiest way to update the ROM anyway?
[Fairphone 4] oddfellow667:
No. I have the same issue with the 2023-02-05 nightly using 4G calls/VoLTE with a german sim card from Congstar.

Probably the integrated updater: Settings -> System -> Updater
[Fairphone 4] Sony make.believe:
Same problem here, but I use IodeOS beta build from 2023-01-31 with german sim card by drillisch (Sim.de). Even without VoLTE I don't hear any dial tone

[Fairphone 4] fanta1312:
Hello, I am using lineageos 20 on my fairphone 4 and I'm very happy with it.

But I bought the Fairphone 4, because of the HDMI USB C port.

Now I bought the ViewSonic TD1655 portable display with touch.

When I connect my phone with the monitor, the touch function is rotated 90°. So when I swipe left to right, it swipes top to bottom.

If I choose desktop mode in developer options it works fine. However, I think the standard environment is perfect for me. maybe that can be changed?

Thank you for your help
[Fairphone 4] b8842dc0:
Thanks for this ROM! I'm having a problem where my in-call volume is very loud and the call volume controls aren't working. Is anybody else having this issue?
[Fairphone 4] b8842dc0:
Sorry, I do think my call volumes controls are working. It is just that the volume is very loud. Lowering the call volume to its lowest setting is still too loud. But it is manageable.
[Fairphone 4] b8842dc0:
I am having an issue where after a reboot, when I place an outgoing call, the person receiving the call cannot hear me, until I toggle the speakerphone setting on/off. After doing that, everything works with outgoing call audio until the next phone reboot.

Fairphone 4 no outgoing audio during calls until speakerphone turned on (#5511) · Issues · LineageOS / issues / android · GitLab

Expected Behavior When a call connects the person on the other end should hear outgoing audio from the Fairphone 4 (FP4)...

Hello people!

I recently bought a Fairphone 4 and flashed Lineage OS on it. Soon I noticed that the battery life felt worse than that of my old Xiaomi Mi A2 Lite. I imagine the most power hungry apps on my phone are Molly (Signal client), Telegram FOSS and Tutanota. I do not have Google Play Services or MicroG installed. On my old Xiaomi I also did not have Google Play Services or MicroG installed.

I wanted to ask if anybody also has this problem.

This is what I could find on the internet:

https://www.reddit.com/r/fairphone/comments/v13ne5

https://www.reddit.com/r/fairphone/comments/11pfxug

https://www.reddit.com/r/fairphone/comments/wup6tp

My build number is:

lineage_FP4-userdebug 13 TQ1A.230205.002 a16d53828e

LineageOS version is:

20-20230319-NIGHTLY-FP4
[Fairphone 4] b8842dc0:
I'm using Lineage 4 Microg, but not having this issue on my FP4. However, I'm not using Molly (Signal client), Telegram FOSS, or Tutanota, either.
[Fairphone 4] flocke000:
I am currently using LOS 20 with Microg and I don't have this problem. I am also using Telegram FOSS, but not the other two apps you mentioned.
[Fairphone 4] hulkjulk:
Hello everyone.

I use now the LOS with microg for a few months.

I still have those issues (Phone is new):

- Phonecalls over usb/aux are very/extremly loud on the lowest step I can choose

- and as well the phone-ringtone-silence till someone is answering the call over VoLTE (not so over 3G)

Does someone or you @mikeioannina know the answer how to solve it?

Thanks alot for the work @mikeioannina !
[Fairphone 4] JulianAT:
This ROM runs very smooth, but there are a few problems with it.

In audio calls made by Teams, the audio of the incoming party sounds high pitched (like Mickey Mouse).

Problem is known at /e/os

Netflix is not compatible regarding to Play Store and even if I install it from apkmirror, it just hangs on "Netflix" logo.

For #1 problem: The following workaround does NOT work:

Settings > accessibility > mono audio: switch on “combining channels …”

I've flashed lineage-20.0-20230402-nightly-FP4-signed.zip with MindTheGapps (MindTheGapps-13.0.0-arm64-20221025_100653.zip).
[Fairphone 4] rcshr:
Hi all, I'm new to the XDA forums and wanted to introduce myself. I'm in the US and using an FP4 running LOS 20 with MindTheGapps. I'm also on the Fairphone forums and have been following those for a while. I'm very grateful for the effort that went into making LOS run on the FP4, because the phone was not usable in the U.S. with the factory OS. I don't have any experience yet developing for android but aspire to start doing so.
[Fairphone 4] ethical_haquer:
Thanks for building this! You might want to include a list of what's working and what's not working, like on this thread. Otherwise, if I want to know if VoLTE works I have to dig through posts to find out.
[Fairphone 4] ondrejlohnisky:
Hello, I am having trouble with my internet access somehow, after last update 23.4.2023. Am i alone?

Constatnt internet restarting, celluar internet and wifi is problem also. :-_/

If anyone is having problem with sensors not working after installation of Ubuntu Touch. Just enable usb debugging with root access, then on PC do

adb root

and

restorecon -FR /mnt/vendor/persist

I feel this solved my issue, i will update this comment. bellow:

I feel like its problem with my SIM Card, but the problem is only when 5G (NR/EvDo) is on LTE works just fine. Maybe its problem with my SIM.
[Fairphone 4] ondrejlohnisky:
I have problem with other people hearing me during calls when i have turned speaker mode on.

Anyone has this problem?
[Fairphone 4] Sappalot Händlhaxn hackn:
Hey people, I have an eSIM and the mobile internet doesn't work, SMS and phone calls work without a problem. Does anybody have an eSIM with working internet?

I am now using LineageOS for microG.

A normal SIM card worked without problems for me.

Edit 13.05.2023: I received a normal SIM card from my provider. It also didn't work. But it works in my old Xiaomi Mi A2 Lite (Lineage OS). I then installed the stock ROM on my Fairphone 4, there the SIM card works. Then reinstalled Lineage OS for MicroG, and again it did not work.

So now I am running stock ROM and the mobile data works. Interestingly, the weird dial tone in Signal Messenger is gone with the Stock ROM. On Lineage OS without MicroG and Lineage OS with MicroG I had a weird dial tone in Signal Messenger.
[Fairphone 4] martinsche:
What's wrong with the Lineage OS server since yesterday?
[Fairphone 4] mtze:
Had a clean installation of lineage-20.0-20230521-nightly-FP4, but no sound over USB-C to HDMI or USB-C to 3.5mm.

Updated to lineage-20.0-20230611-nightly and the boot times are longer, I can't turn on Wifi, and audio is fully broken now. No audio player works, Poweramp even starts by displaying a "audio engine failed to load" error.

I used the OTA updater, how can I roll back to the previous installed version? The OTA updater creates recovery backups, right?

I don't have the time to wipe and reconfigure the whole phone, if there aren't any backups, can I just reinstall a previous lineage-20.0-20230521-nightly-FP4 build over this new one?

---

Update: Fixed the blunder, but back at square one with lack of audio over USB-C.

My fix was:

- Fully uninstalled Magisk

- Exported the OTA update and moved it to the SD card

- Rebooted into Recovery and reinstalled the OTA update

- Sideloaded Gapps over adb

- Rebooted

All seems back to normal except that USB-C still won't do sound either via a USB-C to 3.5mm adapter or a USB-C to HDMI adapter. Both of these adapters work fine with other devices.

I'v received my Fairphone 4 yesterday, already setup with stock ROM but I'd like to switch to LOS because of features and GApps...

BUT officially, there isn't any Android 13 and I'm asking whether LOS 20 reuses the Android 12 Kernel (like on Sony XZ2C) and how it overall is, whether there are some issues with battery life, performance, stability, ...

Edit: Also is Android 13 kernel based on Android 12 like copy-paste or are there adjustment made?
[Fairphone 4] chaosjug:
Hi!

I didn't find a lineageos 21 thread yet, so I'll post here. I updated my FP4 from eOS to lineageos 21 and now Audio Books are not working with the Onleihe app anymore.

Does anyone know if Widevine is supposed to be working with this ROM? DRM Info shows Widevine L1 but I get license errors. Widevine L3 would probably enough, as Onleihe is working on a OnePlus 3 where DRM Info says it only has L3.
[Fairphone 4] mtze:
Hey folks, this seems to be a very common issue with the Fairphone 4 and I'm experiencing it as well.

There's a whole years-long thread at their official forum and it seems like an update to their OS added some kind of detection to ignore when these ghost inputs happen.

Unfortunately it doesn't seem like the FP4's Lineage build has the same fix.

Is there an alternative way to solve this?

Thanks in advance.
