LineageOS 24.0 is out: Android 17, easier installs, and a ROM that stays outside Google's new rules

Android 17 arrived in June, and plenty of phones will never get it from their makers. LineageOS is how a lot of them get it anyway. The team published LineageOS 24.0 today, built on Android 17 and released as Changelog 32, with a fresh look, browser-based flashing tools and newer security patches.

The short version

Built on Android 17, announced October 11.
More bundled apps get Material 3 Expressive, and tablet and TV layouts were reworked.
Security patches from August 2025 through October 2026 are merged into branches 18.1 through 24.0.
Web flashing tools can handle the flashing step, but not the whole install.
Your phone may not have an official 24.0 build yet, so check before you flash.

What's new in 24.0

The most visible change is the look. LineageOS began moving to Material 3 Expressive in 23.2, when Twelve (the music player), Deskclock and ExactCalculator got it. In 24 it reaches more of the bundled apps, including the Canvas image editor, the Catapult launcher for Android TV and the Jelly browser. Tablet and TV layouts were also reworked quite a lot, so those devices get something out of this release too.

Google released Android 17 in June, and the team has spent the months since porting LineageOS's own features onto it. According to the team, Android 17's first release is mostly small improvements and some UI and UX polish, and years of keeping up with Google's big refactors meant the port went faster than they expected. On security, the old 15.1, 16.0 and 17.1 branches are patched up to November 2025.

Installing is less of a chore

The announcement mentions web flashing tools that use WebUSB, so a compatible phone talks to your browser directly and you don't have to track down a separate flashing program. They first appeared in LineageOS's July 7 Summertime Updates post and cover ADB, Fastboot, Samsung's Odin protocol and Amlogic's burn mode. They only handle the flashing step, though. You still need to follow the install guide for your device on the wiki.

Updates got easier too. The redesigned Updater app from that same post shows an update's security patch level before you install it, and A/B OTA packages stream by default, which uses less space and applies faster.

Which phones?

Official builds arrive device by device, and the 23.2 roster shows the kind of hardware LineageOS keeps going. It includes the Pixel 4 and OnePlus 7, and the July update added the Galaxy S23, Xperia 1 VI, Xperia 10 VII and Fairphone 6. Whether your phone already has an official 24.0 build is something to check on the downloads page and your device's wiki entry.

Where Google's new rules fit in

Google's Android Developer Verification, which LineageOS described in July as rolling out regionally from September 2026 and globally by 2027, requires apps on certified devices to come from registered developers, whatever the install source. LineageOS says this won't affect it directly. The team's July post puts it plainly:

"We have not ever, nor do we intend to ever, ship GMS."
LineageOS team, Developer Verification post, July 4, 2026

Without Google Mobile Services and without Google's certification, LineageOS has no obligation to install Google's verifier. One wrinkle: a Google apps package you flash yourself could bundle it, though the team knows of no reason one would, and you could switch packages if one did. If Google ever folds the feature into Play Services, LineageOS says it will disable it globally. The project has also signed the "Keep Android Open" petition.

Should you flash it now?

If this is your only phone, the safe move is to wait for an official 24.0 build for your exact device. Unofficial Android 17 builds have been around for weeks, and early builds tend to have gaps. A DroidWin roundup of them listed double-tap-to-wake as broken on a OnePlus 15 and VoLTE/VoWiFi as not working on a Galaxy S20 FE.

When you do go ahead:

Check the downloads page and your device's wiki page first.
Back up your data.
Follow your device's install or upgrade guide, and make sure your firmware and recovery are current.
If you want Google apps, flash the add-on package for Android 17 as well.

About the version numbers

The 23 series was Android 16. 23.0 used the initial release, and 23.2 followed on February 8, 2026 after the team rebased onto two large AOSP releases. Google moved AOSP to a biannual cadence, so in Changelog 31 LineageOS said work on each new point release would start every six months. Android 17 means 24.
