Why would one want completely outdated hardware (see Ulefone Armor X8) with a closed source variant of SailfishOS? To me this sounds as a far worse combination than the Jolla C2 (still outdated but much better hardware) or a Sony Xperia with SailfishX.
Furthermore I am unable to find the Ulefone Armor X8 offered with AuroraOS, only with Android 10. Do you have a source?
