Why is samsung a52 supported but not a51

they are the same, why not just add a51 to the list, maybe there is an addidational camera in a52 but i do not think it changes the entire hardware

If they are the same, then why does A52 have official LineageOS support, and A51 doesn’t? … https://wiki.lineageos.org/devices/#samsung
/e/OS is based on LineageOS.

…are they the same ? (spoiler: no, they aren’t)

Anyway seems that some (re)sources are available for A51 too:
