    Work well ril_patch_ss.zip but loud speaker sound quality very unstable
    And music sound quality very unstable
    And notification light not work
    Thanks for reporting for Calling issues.
    But sound quality is totally fine on my device, tested so many times.
    And I'm using the same audio configs as CM14 uses.

    Notification LED works for me too...

    I see lots of complaining here so I just wanted to say thank you for reviving this aging device! I still use it as a backup phone so this is perfect.

    When is the next update is coming?
    When the next monthly security patches has been merged into LOS's sources.
    But actually asking ETA is not a good thing for me, I will release updates if I think it's needed.

    Please update to a5dwg dual sim Asia
    Next build will release a5dwg variant, don't quote the whole thread and spam here thanks.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
