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 in 0.4.23
- Pixel systems run much cooler. On the first Galaxy S25 Ultra with the Pixel 9 Pro XL system, one of Pixel's own services (Connectivity Thermal Power Manager, made for Google's modem) crashed and restarted about 95 times a minute, at full processor speed: the phone reached 54 °C. It is now left out of the session on every Pixel system.
- Cool down when hot (new, on by default, in Advanced). One UI's own heat control does not run while the other system is on, so nothing slowed the processor down. From 45 °C OneOS now lowers the processor's top speed in steps until the phone cools, and gives full speed back when it is cool and when you return to One UI. You can switch it off in Advanced.
- 120 Hz on Pixel systems. They often drew at 60 Hz even though the screen ran at 120 Hz; they now draw at 120 Hz.
- Less work in the background: the system no longer keeps recalculating storage quotas that OneOS does not let it set.
- Blur: in Android 17 the switch moved to Settings > Accessibility > Color and motion > Reduce blur effects. "Allow window-level blurs" is still listed in Developer options but no longer does anything.
Galaxy S25 Ultra with the Pixel 9 Pro XL system, first report: it starts, runs Google's setup, has mobile data, Bluetooth and both speakers, and Back to One UI works. Calls have not been tried yet.
Known issue: the camera in Pixel systems. Samsung's camera service and the Pixel system disagree on parts of the camera interface, so most camera apps fail or open only some cameras, and the flashlight tile does not work. A fix is being worked on; it is not in this version. Pixel Camera itself will not work on Galaxy phones in any case (it needs Google's camera hardware support).
[!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.
