The first of all, thank you for your work, time you spend building that ROM and the result! :) :good:

Actually I don't know where to report bugs and write suggestions or questions. In main thread you mentioned carbon website. But this is unofficial build so that's why I'm writing here for now:

1. Offline charging displays black screen
2. Sound in all sections is not working properly - when I adjust it to my preferences it didn't set higher than a half. Then when I stopped playing music and set it for max then play it worked

1. Is there any way to use expanded desktop mode and navigation gestures with custom launcher (I really like and always use Xperia launcher 11.3.A.0.17).

2. Z3C doesn't have OLED display. So is it sensible to use pixels reduction to improve battery life performance?

3. Are you going to update this ROM?

Edit: currently I'm back to LOS, but I really want more features

    CarbonROM is an aftermarket firmware based on the Android Open Source Project. We are dedicated to fast, stable, and feature-filled roms, honesty and communication with our users, and openness with our code. We like frequent builds, with the very latest and greatest hardware support and fixes. We strive to not only provide you with the best rom we can build, but also to give back to the Android community and our fellow developers. For us, this is about creating something we can be proud of and hope you will enjoy.

    NOTICE: THIS IS AN EARLY BUILD. There will be changes in the release branches like changed/removed features or similiar.

    • We found the camera to be a little wonky on occasion. Working on that. Currently waiting between pictures is working around the issue.
    • Video Recording is not working

    Please feel free to look, build, and use our code at CarbonROM's GitHub...

    While we make every effort to test these builds as much as possible, we are not responsible for anything that may happen to your device, family, pets, or perception of reality. We ask that you do your part to know your device and know how to recover from problems before you flash! These builds are experimental and can contain Bugs (as listed above). Make sure to do backups.

    We spend an astonishing amount of time developing this software. We can't spend much time on XDA as a result, so if you need support, please try the following:

    1) Search. Search, search, search. Yes, you. I don't care how unique or important your question is, it's very likely someone has adressed it already. Especially if you're even close to new at this.
    2) Read our FAQ, which can be found on our website. Carbon FAQ
    3) Ask a question in your device forum. Someone will no doubt try to help you. Warning: this help may come in the form of telling you it's a dumb question that has been asked before. See step 1 - such are the perils of asking questions when you haven't done the research yourself. Android is about helping yourself.
    4) Join our Discord server! There, you can connect with other Carbon users and our developers, and you can get quicker responses to your bug reports. The invite link is right below.
    5) Please keep bugreports to this thread or Discord. Do NOT create a Jira ticket. This is still in early development so we don't accept any bugreports yet.

Your support means the world to us! If you've enjoyed Carbon, please consider a donation toward this goal. Thank you, and we hope you continue to enjoy Carbon!

    New build

    Just finished uploading a new build.

    Small Changelog:

    Other reported bugs are currently WIP. E.g. we made some breakthroughs on Video recording, more on that soon.
    New update with a bunch of updates (basically all above and more) will come later.

    Should be pretty much ready to go official now.

    ALSO fixed the issue that would not allow booting to the recovery via init_sony (the Press Volume when LED lights up thing) when Magisk 19 or higher is installed.

    Fix is here:

    That fix has also been applied to cr-6.1.

    New build contains plenty of fixes and should be the last build before we go official unless another issue appears.

    Booting to recovery with Magisk 19.x is fixed too, otherwise there's fixes from @NeoArian, @koron393 and @drakonizer.
