LineageOS maintainers have begun releasing stable builds of version 24.0, based on Android 17. In this article, we summarize the changes to the core Android Open Source Project (AOSP) and to LineageOS's apps and add-ons.
Summary of Updates in Android 17
Android 17’s AOSP release notes focus mainly on platform, device-maker, and developer changes. The biggest differences from Android 16 are:
| Subject | Android 17 Additions and Changes |
| Memory and stability | Adds the Memory Limiter to constrain excessive app memory use, plus a process memory guardian daemon and a memory-management daemon for ZRAM maintenance. Android 16’s notes include trade-in health diagnostics; Android 17 expands those diagnostics with camera geometry and UICC slot information. |
| Privacy and permissions | Adds a system Contact Picker so apps can access only the contact details a user selects, without requesting broad contact access. It also adds status-bar location indicators when a nonsystem app accesses location in the foreground. |
| Display and large screens | Adds per-display desktop windowing and more configuration options for large-screen app compatibility. |
| Connectivity | Can automatically route over-the-top voice and video calls through premium network connections, such as a premium 5G slice. Its out-of-band ranging specifications also add support for switching ranging technologies during a session and reporting motion changes. |
| Media | Adds platform and parser support for decoding Versatile Video Coding (VVC); a device still needs a compatible decoder supplied and enabled by its manufacturer. |
| Audio and Bluetooth | For devices adopting the new audio architecture, SCO routing moves from Bluetooth framework management to the Android audio framework. |
| Security | Adds secure-element prewarming that can reduce lock-screen credential verification latency, and improves lockout feedback. It also changes the implementation path for hardware-wrapped storage keys on newly launching devices. |
| Architecture and AOSP development | ION is no longer supported. Android 17’s AOSP build instructions also note that the source tree is read-only during builds. |
Overview of LineageOS 24.0 Changes
LineageOS 24.0 is based on Android 17 and brings a major OS upgrade alongside refreshed apps, installation tools, and maintenance changes. The project says 24.0 reached feature and stability parity with 23.2 for its initial rollout; builds are arriving for supported devices as maintainers prepare them.
- Refreshed built-in apps: Core apps adopt Google’s Material Design 3 Expressive styling. The new Canvas editor handles basic image edits such as cropping, white-balance adjustments, and filters.
- Updater improvements: The redesigned Updater has a cleaner interface and improved animations. On supported A/B devices, updates stream by default, which is intended to shorten installation time.
- Jelly and Twelve updates: Jelly can create shortcuts for web apps. Twelve loads large music libraries faster, improves Jellyfin support, and adds a tab for frequently played tracks.
- Optional browser-based flashing tools: WebUSB tools cover ADB/Fastboot, Amlogic Burn, and Samsung Odin workflows, reducing the need for separate desktop flashing utilities in compatible cases. The project still recommends its device-specific installation guides.
- Accessibility and documentation: The project reports an accessibility audit of its apps and installation process, some changes to Recovery, an expanded FAQ, and a redesigned wiki.
- Security patches: The announcement describes patches from August 2025 through October 2026 across supported branches, with patches for older branches where possible.
- Older-kernel support: Devices on Linux kernels 4.4 and 4.9 are limited to LineageOS 22.2; the project says they will continue receiving monthly security patches there, but won’t be submitted for 23.2 or 24.0 builds.
Conclusion
LineageOS 24.0 pairs the Android 17 upgrade with a visual refresh and practical improvements to updates, media apps, accessibility, and installation.
Android 17’s notes emphasize memory safeguards, more granular privacy controls, large-screen windowing, connectivity and media additions, and updated device-security mechanisms. These are AOSP/platform changes—not a list of Google proprietary apps or services.
