Heyyo
@rafman79 , I am the guy who is making those LineageOS 18.1 builds for heart. I do not own a heart, but I do own a zippo (Lenovo Z6 Pro) and I am the official maintainer of both TWRP and LineageOS for zippo. I saw there was a lack of maintainers for heart, so I decided to help since we have an sm8150-common tree made for the purpose of supporting zippo and heart.
Those builds are experimental since I can't test them myself (as mentioned, I don't own a heart), so there's still some work to still be done and progress is a little slow since all I can do is send out test builds and wait for someone to test them and report back and send me logcat.
Since I don't own a heart, that also means I can't maintain official builds for it, so my goal is to try and get it stable and working correctly and then someone who owns a heart will hopefully step up and maintain official builds for it...
