LineageOS is currently installed on 1.5M Android devices

Original Article ↗ Hacker News Discussion ↗

LineageOS, a popular open-source Android replacement, is praised for extending the life of older phones, reducing bloat, and enabling simplified, privacy‑respecting setups — from “dumb smartphones” for seniors to de‑Googled daily drivers. Commenters highlight trade-offs around security, noting that LineageOS prioritizes device compatibility and longevity while projects like GrapheneOS focus more strictly on hardening, and that banking and government apps often penalize custom ROMs via Google’s Play Integrity checks. Many see these restrictions, along with complex installation and bootloader policies, as symptoms of a broader trend toward locked‑down mobile ecosystems that sideline user control and accessibility.

Use cases and benefits

  • Many use LineageOS to extend life of old phones, especially for low‑income users and elderly residents in care homes.
  • Common pattern: strip device down to core apps (phone, SMS, contacts), disable data/Wi‑Fi, creating a “dumb smartphone” that is simpler than specialized senior phones.
  • Users report noticeably better performance, responsiveness, and battery life compared with stock ROMs, plus removal of OEM bloatware and ads.
  • LineageOS helps bypass OEM abandonment (e.g., Android 9 end‑of‑support) so devices remain usable with newer apps and certificates.

Accessibility and UX for seniors

  • Several comments highlight how modern smartphone UIs are confusing for older or impaired users: tiny icons, hidden gestures, multi‑step buttons, and indistinguishable interactive elements.
  • Some criticize “senior phones” (e.g., certain Doro models) as poorly designed and predatory despite their marketing. Others argue they fill an important niche.
  • Proposals range from better accessibility incentives to laws mandating accessible UIs or open, customizable UI layers; others strongly oppose UI regulation.

Security and privacy posture

  • LineageOS is generally seen as focused on longevity and de‑bloating rather than maximum security or privacy.
  • Critiques: lack of Verified Boot by default, older unpatched kernels on some devices, and unlocked bootloaders reduce security compared with fully supported stock or hardened ROMs.
  • GrapheneOS is repeatedly recommended as the “serious” security option on Pixels; DivestOS and /e/OS are mentioned as variants with extra hardening or prebundled microG.

Banking apps, SafetyNet, and Play Integrity

  • A major pain point: many banking, government, and even loyalty apps refuse to run on custom ROMs or rooted devices, driving some users back to stock Android or iOS.
  • Others report success using Magisk/Zygisk, microG, or specific devices that still pass Google’s checks, but describe it as a fragile cat‑and‑mouse game.
  • Several argue Play Integrity/SafetyNet is more about enforcing OEM/Google control than real security, noting it’s bypassable while blocking legitimate secure custom ROM use.

Devices, installation, and ecosystem

  • Pixels, some OnePlus and Motorola models, and Fairphone are commonly recommended due to unlockable bootloaders and good LineageOS support; Xiaomi support is possible but unlocking is called painful.
  • Installation is seen as significantly more technical and risky than installing a desktop OS; some report bricked devices from minor hardware variations.
  • LineageOS is praised as a “standard Android” experience without OEM theming; some users donate via Patreon and stress its importance for reducing e‑waste.
