OneOS puts another Android system next to One UI on a rooted Samsung Galaxy and switches between them without flashing anything. You switch from the OneOS app and come back with Back to One UI inside the other system, or by holding Volume Up + Volume Down for 3 seconds.
What's new since 0.4.19
- A Pixel for the Galaxy S25 Ultra, S25, S25+ and S24 Ultra (untested, please report): Google's Pixel 9 Pro XL system with Google Play and Google's apps (0.4.22). The Pixel 11 images need a CPU feature these phones' chips do not have; the Pixel 9 Pro XL's system does not use it. Nobody has run a Pixel on these phones yet: if the screen stays black, OneOS returns to One UI by itself; please share the session logs.
- Exynos phones (Galaxy S26+ Exynos, Galaxy Z Flip7): ColorOS now starts there (0.4.20), but both phones still restarted a few minutes into a session: Samsung's software watchdog ran out. 0.4.22 switches it off through One UI's own setting while the other system runs, and puts it back when you return. Untested; please report, with the session logs.
- Galaxy Z Fold8 Ultra: half-folded postures and the unfold animation for ColorOS and the Pixel 11 Fold, from Samsung's hinge sensor (0.4.21), built on the Galaxy Z Fold8 work in pull request [#1], thanks to @thatjoshguy67 (credited in the app's About screen).
[!WARNING] Experimental. It can break your phone's data. Do not try this unless you know what you are doing. Before switching you must back up your accounts and data, and remove the screen lock (PIN, pattern, password, fingerprint, face). Read the warnings in the README first.
