And for those still needing Google services for corporate or whatever reasons, there’s a strong solution at Google Play Services on Xperia 10 III Sailfish 4.4.0.64 (now 5.0.0.73) - #92 by lkraav that I’m (and probably many silent thread lurkers) daily-driving hard. Mostly everything works, aside from some potential deep-layer hiccups like Google Workspace MDM etc.
(PS Really, 12 GB RAM is so welcome. At strong native + Android app load, X10III starts out snappy, but as we run close to memory and ZRAM limits, swap usage can have really laggy UX for a while until low-memory killer processes figure their stuff.)
