Hi, first of all great job Bernie, this is an awesome ROM as it made the z5c of my gf pretty smooth.
I just upgraded it to the newest version with the hope that microphone gain would finally be on an adequate level.
Sadly, it is still very low gain, so that you really have to shout into the mic in order to get heard by the person on the other side on speach recordings on whatsapp.
Is there a way to fix that issue? Maybe I can also try to fix it if you can give me a little bit of advise on how to do it.
Best Greetings from Hanover!

Is this using bluetooth? I get good volumes through the phone mic and wired headsets but whenever I use a bluetooth headset (I've tried several) the people on the other end complain that they can't hear me. I've thought it was maybe a problem with the bluetooth devices but maybe it's not...

I'm on the 20210810.211238 update though if that makes any difference.

Has anyone had issues with using the lineageOS calendar app?

org.lineageos.etar (version 11)

When I try to create an event, there's a lag of up to 20 seconds with any action (keyboard popping up, activating a different text field, entering event name, modifying time/date, ...).

Message pops up "Calendar isn't responding .. Close app / Wait"

I'm using DAVx5 and have a calendar account synced.

I'm still on the los 20220413 build.

logcat doesn't look like there's anything interesting/useful.
Same here. I installed the regular Etar from F-Droid, and that one works fine. Also disabled the LOS Etar, so it won't be in the way.

Tried the 20220715.142108 ROM and found two things not working; microphone volume level on Whatsapp and FB messenger calls is way too low, and video recording on any camera app was very laggy at first and then stopped working completely (this I noticed on the default camera app, Open Camera and Instagram app). The default camera app gives an error "Could not start media recorder", the others just won't record video.

    Hi all:

    Here is a LineageOS 18.1 ROM for Z5 compact (suzuran).

    Download 2022-08-15

    This is a 7z archive with the zip'ed ROM and the md5 file in it. Please unpack this archive, copy the included two files somewhere to your device, reboot into TWRP and flash this zip file. Enable md5sum checking. The zip file itself is not signed, so you have to disable zip verification.

    • This ROM needs a clean install, old /data may cause problems!
    • This ROM is NOT pre-rooted. For rooting you can use Magisk.
    • It is highly recommended that your device is running (or HAS RUN in the past!) the latest stock ROM from Sony (32.4.A.1.54) before flashing this ROM.
      Otherwise the baseband files may not match.
    • Audio
    • Bluetooth
    • Camera; both built-in camera (Snap) and 3-rd party camera apps.

    Use this ROM at your own risk! It comes without any warranty! I'm not responsible for any damage! If you don't agree with that, don't try to flash this ROM in any way.


    • Added Aurora-Store, F-Droid and UnifiedNLP! If you don't want this, simply de-install it.
    • I've set maximum speaker volume to a higher value.
    • I've increased microphone gain.
    • I've changed the microfone gain to avoid echo in phone calls.


    • If you're running into an error, please search in this thread if this error is already posted, before you post it again!
      If not, I need a LOG to see what went wrong. Without a LOG I can't help you!
      A LOG can be fetched by connecting the device with an USB cable to your PC and then by typing these commands line by line:
      adb root
      adb shell logcat -b all -d > logcat
      Send my this LOG file via PM.
    • If you think this could be a SELinux related issue, please try to set the device to permissive mode first.
      If the issue is gone, I need the policy file too (plus LOG). Fetch it by typing this line in a terminal:
      adb pull /sys/fs/selinux/policy
    • If you stuck in a bootloop you can fetch a LOG with this trick:
      • Press the power button and the volume up button together until the device shuts down.
      • HOLD the power button.
      • Release the volume up button and press the volume down button immediately after releasing the volmue up button.
      • The device should start into TWRP recovery.
      • Tap on "Advanced", then on "Terminal" and enter these commands line by line:
        cd sys/fs/pstore
        cp * /sdcard
      • Send me the copied file(s), if any, via PM.

    One last request:

    Please, do not ask about problems for which my ROM is not responsible.
    From now on I will only react to problems that I can reproduce and that are caused by my ROM.

    I'm sorry for that, but I'm developing this ROM in my spare time and I still have a normal life.
