Sailfish Mobile OS

Original Article ↗ Hacker News Discussion ↗

Overall sentiment on Sailfish OS

  • Long-time users describe Sailfish as usable as a daily driver if needs are modest and rough edges are acceptable.
  • Some consider it “best mobile OS” with a simple, consistent UX and strong offline maps.
  • Others report poor UX, slow UI, awkward workflows (e.g., attaching photos to messages), and ultimately switched back to Android or hardened Android ROMs.

UI/UX and gestures

  • Gesture-driven interface (edge vs inner swipes, drag-down menus) is polarizing.
    • Fans find it elegant, one-handed, and ahead of its time (heritage from Maemo/Meego/N9).
    • Critics find it unintuitive, hard to discover, gesture-heavy, and sensitive to cases/screen protectors.
  • Visual design is seen as either pleasantly minimalist or ugly/retro (dithered, TUI-like).

Android app support and app ecosystem

  • Native app ecosystem is thin; many apps are hobby-grade.
  • Official Android support (Alien Dalvik) is described as “hit and miss”:
    • Some run major apps (Signal, WhatsApp, browsers) fine.
    • Others report networking/GPS issues, instability, and incompatibility with banking and security-sensitive apps (SafetyNet / Play Integrity).
  • Waydroid is used on some community ports but has limitations (e.g., lockscreen, some app refusals).

Architecture, libhybris, and hardware

  • Sailfish uses libhybris to talk to Android drivers; you must flash Android first and reuse its kernel and blobs (camera, GPU, modem, RIL).
  • This is seen as a pragmatic necessity a decade ago, but also a technical debt that entrenches Android’s kernel/driver model.
  • Official support is focused on specific Sony Xperia models; community ports exist for various OnePlus, Motorola, Xiaomi, etc., but usually without official Android app support.
  • Some report issues like slow cameras, GPS quirks, VoLTE gaps, or regional SIM problems.

Openness, business history, and geopolitics

  • Sailfish markets as an alternative to Android but key UI and components are proprietary; this is a deal-breaker for some.
  • Past Russian investment and a derivative (Aurora OS) used by Russian state entities are controversial.
  • Jolla restructured, shed Russian ownership, and continues under a new name; some see this as principled, others as “too late” or still wary.

Position among alternative mobile OSes

  • Frequently compared to Maemo/Meego, Ubuntu Touch, Plasma Mobile, Mobian, postmarketOS, webOS.
  • Many feel all these offer nicer UX than Android but fail on app availability, VoLTE, and polish.
  • Consensus: true third mobile ecosystem remains niche without a major hardware backer and broad app support.
