I don’t know if this post fits here but the lineage os community has no traffic.
MIUI is bloated and limiting, so I decided to switch to lineageos, however, it doesn’t support my phone. Do I just wait, or is there anything I can do?
You should check XDA developers forum for something like this. People usually posts unofficial lineageos build to support a particular phone model there. Just note that an unofficial build might be more buggy, and you'll have to trust the maker not putting any malware on the rom
