VERDICT

Should I use CalyxOS?

Privacy-focused, de-Googled Android operating system - calyxos.org

Depends. Worth installing if you're a privacy-minded individual with a supported Pixel or Fairphone and can flash a device — it's free and well-liked. Skip it if you need maximum hardening or guaranteed update cadence; GrapheneOS is the community's stronger pick there.

Confidence

Medium. Based on 40+ public sources: official docs, security notices, Reddit reviews, and independent researcher comparisons. User quotes truncated in source snippets, so verbatim quotes are limited.
