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 0.4.29

  • Send to the OneOS team. After a session, open Last session and tap Send to the OneOS team. Say whether the system started, tick what worked and what had problems (screen, Wi-Fi, mobile data, calls, SMS, Bluetooth, sound, camera, Google, location, Back to One UI, heat, and both screens on a Fold), and add a note or your Telegram name if you like. The logs go straight to the team: no more posting zips by hand.
  • By default the app sends a short log: the first minutes after the switch and the last two before it ended, usually under 2 MB. When you tick a problem, it sends the whole session's log, because we can't tell when you tried it. You can always switch that yourself.
  • The logs are the same file Share sends, with personal data already removed. Reports are kept for 30 days. Share and Save are still there, and if sending fails the app offers Share instead.
  • OneOS Probe has the same button for its phone report.
  • Compatibility table. What everyone reports is counted in docs/compatibility.md (github.com): per OneOS version, phone and system, how many sessions started and what worked. Only the answers are counted: no names, notes or phone details.
  • New phones, untested:
  • Galaxy A57 (SM-A576B, Exynos) with both Find X9 Ultra builds and Infinity-X. It's the first A-series phone, and Exynos phones have had only a few test sessions so far.
  • Galaxy Z Flip5 (SM-F731B) with the same systems, used as a phone on the main screen. It has the Galaxy S23's chip and older vendor software, so like the S23 it will most likely not start yet. Please send the logs.
  • New address. OneOS now lives at https://github.com/fahadalijaved/OneOS. The old address forwards there.

[!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.
