(I can’t find a way to send private messages.) @noalternative Enjoy LineageOS w/ MicroG. It sounds like we’ll never get official Lineage 15.1 on S4 because it requires some reversions (see the FAQs: [CLOSED]LINEAGEOS 17.1-microG_ready for Samsung S4 i9505 | XDA Forums ). There are unofficial builds, but the one I’m using from Exodusnick is still a little laggy and quirky as of the Jan 1 update.
