OneOS Files

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 0.4.28

Fixes for Infinity-X 4.1, from the first test sessions. Thank you for the logs.

• Infinity-X stopped a few seconds after the switch. Its emergency alerts module (cell broadcast) is signed with a different key from the network modules the other system shares with One UI, and Android stopped the whole system on the mismatch. OneOS now keeps One UI's module, the same way it already keeps One UI's tethering module.
• Galaxy S23 series: the screen stayed black with Infinity-X. The S23's display and audio drivers use an older interface that Infinity-X expected to be missing. OneOS now connects Infinity-X to them on phones that need it.
• Faster way back after a crash. If the other system's display stops, OneOS now goes back to One UI after about 30 seconds instead of 150. You no longer need to force a restart, which also loses temporary root.

The Infinity-X image is unchanged: you don't need to download it again.

Please test Infinity-X again

1. Install the new app for your phone, open OneOS and tap Update.
2. Switch to Infinity-X. Check that it starts, and try Google sign-in, mobile data, Wi-Fi, calls, the camera (with a Camera2 app) and Back to One UI.
3. On a Fold, check both screens when you fold and unfold.

Tell us in the OneOS Telegram group how it went, and send the session logs if anything did not work.

[!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.

Downloads

The app and the system images are on the OneOS download folder: https://gofile.io/d/A2PSsxv8

Download one app, the one for your phone. The system images are the same as in 0.4.27.

The app checks every file against the size and SHA-256 built into it. If Android says the app is not installed, the download is incomplete. The exact sizes and MD5s:

Already set up? Install the new file over the old one, open OneOS and tap Update.

Phone not listed? Run OneOS Probe and post its report in Phone reports in the OneOS Telegram group.
