> Currently my Samsung Android device is at Dec 2018 patchlevel and nothing I can do about it.

Have you checked whether there's a LineageOS build for your device? https://wiki.lineageos.org/devices/#samsung (Darker links indicate a build is maintained and available.)

Unfortunately, based on how the devices are supported by volunteer work, supported hardware has large gaps.

My Samsung galaxy S6 (march 2018 patch level) wasn't supported the last few times I checked, but older galaxy models were.

Lineage are quite aggressive in dropping older hardware since they pivoted towards 'experience'. My 2013 Galaxy S4 is no longer supported.
