OneOS 0.4.51: one small app that updates itself, five new phones, Samsung IMS and Camera on Pixel

Install this one by hand, once. From 0.4.51 on, OneOS updates itself: when a new version is out, the launch screen shows an Update banner. With root it installs on its own and reopens; without root, Android's installer asks you to confirm. Fixes for a system come the same way: update, set the system up again, and only the files that changed download.

One APK for every phone. No more fold, s26 and s25 downloads. OneOS downloads only the files your phone's system needs when you set it up, checks every one, and keeps what didn't change.

System images are on Google Drive (link below). The download guide lists every image with the phones it is for, so you know which .gz to get.

New phones (untested: please send a report)

Galaxy S25 Edge, Galaxy S24 FE, Galaxy A26, Galaxy A17 and Galaxy A16 5G (Exynos, SM-A166U). The S22s, S23 FE, A06, A16 with MediaTek, A34, M53, E55 and the Tab S10 FE and Tab S11 are still on One UI 8 or 8.5 (Android 16); every system here is Android 17, so they come once those phones get One UI 9.

Pixel systems

• Samsung IMS: VoLTE calls and SMS over IMS on the Pixel 11 Fold, Pixel 11 Pro and Pixel 9 Pro XL (they had no IMS at all, so SMS failed on VoLTE-only carriers such as AT&T).
• Samsung Camera, as on ColorOS and Nothing OS, and apps that use the old camera API or the NDK camera now open the camera.

ColorOS

• The Find X9 Ultra global (IN) build is now the ColorOS of every S, A and Flip phone; the debloated Find X9 Ultra build is retired. If you had it set up, set up the global build.
• Theme Store: shown on the Find N6 build, opens on every Galaxy, and its privacy agreement is kept.

Fixes

• Back to One UI no longer makes One UI roll back its system updates. One UI's crash recovery took the switch and return for a boot loop, rolled back the latest Google Play system update and restarted the phone. Fixed.
• Apps you uninstall in another system stay uninstalled (they came back in the next session).
• Set up with a downloaded file starts the setup instead of asking for the file again.
• Infinity-X: the in-system OneOS app no longer closes. HyperOS, Infinity-X and Nothing OS get Samsung IMS. Exynos phones: the ColorOS home screen shows its icons. Setup keeps running when you leave the app, and shows real progress.
• The other system's app: where you are, the ways back to One UI (the app, the shortcut tile, the volume keys), and a checklist.

Known issues

• Theme Store opens but shows No Data: OPPO's server sends nothing to it yet.
• Calls and SMS on the Pixel systems are new: please report how they work on your carrier.
• Rarely, Back to One UI restarts the phone instead of returning in place; OneOS now logs why, so please send the log if it happens.

If something goes wrong, the phone comes back to One UI by itself. Please send the log with Send to the OneOS team (Last session).
