LineageOS 24 arrives on Android 17 ahead of schedule

LineageOS 24 is official, built on Android 17 and released ahead of schedule, 9to5Google reported. Existing builds can upgrade, but device builds arrive over the coming weeks as maintainers bring each one up to compliance.

Kernel 4.4 and 4.9 devices can't be submitted for 23.2 or 24.0 builds and remain on 22.2 with monthly patches. Existing builds can upgrade to LineageOS 24. 24.0 has security patches from August 2025 through October 2026. Maintainers bring devices to compliance in coming weeks.

What happened

  • Almost all core Lineage apps now use Material Design 3 Expressive, and a new built-in editor called Canvas handles cropping, white balance and filters alongside Glimpse and Aperture.
  • The Updater gets a visual overhaul and streamed updates by default, intended to cut installation times on A/B devices.
  • New optional WebUSB tools run in the browser for ADB Fastboot, Amlogic Burn and Samsung Odin installs.
  • Devices on Linux kernel 4.4 or 4.9 can no longer be submitted for 23.2 or 24.0 builds, and stay on 22.2 with monthly security patches.

Why it matters

  • decision Anyone promising an upgrade date to a team or household has to check the device's status on the LineageOS wiki first, because that is where 9to5Google sends readers to confirm readiness.
  • constraint Owners of phones on those two kernels will not see a 24.0 build, so 22.2 and its monthly patches are the version to plan around.
  • capability First-time installers can skip desktop software for three common flashing protocols, while the wiki guides stay the supported route for everyone else.

Picture an owner who opens the updater on the day the announcement lands and finds nothing waiting. That fits the report. A maintainer has to bring each device up to compliance before its build appears [10], and 9to5Google did not list which devices have one today. The pitch is a release number and a design refresh. What happens on a given phone is a build made for that phone.

The release also carries smaller changes. The music player Twelve loads large libraries faster, improves Jellyfin support and adds a most-played tab, and the Jelly browser can run PWA-like apps from a new shortcut [6]. For maintainers, the team expanded common kernels for Qualcomm and Amlogic chips and merged legacy device shims, to simplify upkeep across popular chips [11].

The browser flash tools are optional. Standard device wiki guides remain the default and fully supported path [8], so a team runbook that points at the wiki needs no edit.

The release includes security patches from August 2025 through October 2026 across supported branches [3]. That is a 14-month span [12], so the patch date on the specific build is worth checking before it is installed.

A 2x2 sorts any device. One axis is the kernel: 4.4 or 4.9 against anything else [9]. The other is whether the wiki yet shows the device ready for 24 [10]. A device on a legacy kernel stays on 22.2 and its monthly patches in either column [9]. A device on another kernel with a ready build gets the upgrade, after a read of its wiki guide. A device on another kernel with no build yet stays on its current build until the wiki shows one. 9to5Google expects rollouts to widen over the coming weeks [10].

What to watch

  • Whether the LineageOS wiki shows 24.0 builds for your specific device as maintainers bring them up to compliance over the coming weeks.
  • Whether 22.2 keeps its monthly security patches for the 4.4 and 4.9 kernel devices that can no longer receive 23.2 or 24.0 builds.
