thanks for the ROM and especially for publishing all the sources.
I have found some issues with it:
* The system is much slower than LOS based on Android 7... that's a bit unfortunate but I guess inevitable.
* hardware navigation keys are not working, it's not clear how to apply the patch linked in this forum post
* sound is coming only out of the phone top speaker. the normal bottom speaker is not working.
* styling is weird (why is dark theme forced by default? there are many places where text is unreadable because of weird colors, for example in the default browser download dialog it's dark grey on top of black; switching to a light theme does not help). but maybe it's android 13 issue, not the ROM issue?
