@NurKeinNeid just did a Format Data and clean install of the 16/01 build and VoLTE is still not working for me somehow, it did work on the very first build I had installed back in December. Any idea what could be causing VoLTE to not work? Is there anything I can try to make it work? I am using just your ROM with no custom kernel or anything. Just wondering what is going on here since it did work for the very first time.

First, awesome work by the devs! I've been running Derp on my 5t since 10.0. Derp rocks!
Recently tried flashing to 12 from 11 and got stuck on the boot screen with the derp owl for about 45 minutes before I killed it. Wiped system, data, storage, cache, everything. Flashed again, rebooted several times, same result. Anybody know anything obvious I missed?

Did you do a Format Data? Which recovery are you using?

You have to format data as well

APN list was changed to CAF instead of Pixels because I was told it's better in general. So I suspect that manually adding or correcting APN would fix your issue I guess if it was fine in December build for you.

I removed all APNs and created a new one manually, still VoLTE is not working. It is working on my partner's Pixel 3A with my SIM in it. Did multiple restarts as well but still it is not working.

OK, so the following has worked for me, not sure how it might affect the calling or the call quality.
1. Change the preferred network type to 'LTE'
2. Switch on VoLTE
3. Voila! It works now!

I am still not getting the VoLTE icon on the statusbar but I made a call and tried surfing the internet and it worked! Can other people with non-working VoLTE also try this and report back??

    I tried deleting phone app using root and reinstalling it. But it's still using gps.
    @NurKeinNeid maybe you can shed some light onto what's happening here
    Phone services (not the Dialer) accesses detailed cellular information which is considered to be location information. It's a base OS component serving the intended purpose and shouldn't worry anyone. I don't know why it's showing up more often now. Just flash latest build from GDrive. It's now excluded. I just don't have time right now to spend a whole day uploading four files to two hosters. I have uploaded official builds on GDrive for both devices already. I just don't find time for the rest.....

    For both devices again. That's why also changes from last dumpling build are in the changelog.

    Device Changes:
    - Sync with latest Lineage changes (includes latest dual sim changes)
    - KeyHandler: Vibrate when switching to and from total silence

    ROM Changes:
    - Merge May Security patch (android-12.1.0_r5)
    - Use system color accent for privacy indicators
    - Let screenshot window ignore screen decorations
    - Add Phone services, Google Search and Google Location History to location indicator whitelist
    - Prevent whitelist packages from appearing in privacy dialog
    - Settings: Fix Android Beam switch bar content
    - ThemePicker: Fixes a crash when lockscreen wallpaper is different from home screen wallpaper, or some other unknown case

    Unable to get updates from derfest updater..
    There was no update pushed via OTA. Not possible with two variants.

    This is a small project based on AOSP. We try to be a platform for beginners and support the Custom ROM community with our own unique contributions as well. This ROM exists thanks to inspiration of AOSiP, Thank you! #StayDerped

    Code:
    /* Your warranty is now void.
    *
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.
    */


    What's broken?

    - Dual sim does not work
    - Mobile data only works on SIM1 slot
    - Reverting to 11 may be difficult and may require reset of internal storage

    Derpfest Beta Update!

    Sorry for the delay. It's my fault. I was not satisfied yesterday. But it turned out it was just me. But that also meant that we now had more time and could add and fix more stuff. Many thanks to all who helped, especially to @idoybh.

    I'm not sure I should push OTA. I think it's safer for the next release. I now have a whole week of free time and can finally devote more time to the ROM. Let's see what we can bring new.
