# OneOS interface: cover and inner screens Captured from the physical Galaxy Z Fold8 (SM-F971B), running the accepted OneOS 0.4.38 debug build on One UI. These are actual app captures, not Figma mockups. The captures precede the upstream 0.4.37 merge; the UI source is unchanged by that merge. No OS switch or update was started for photography. ## New icon and wordmark New OneOS blue icon with two overlapping white and pale-blue panels The launcher uses separate adaptive foreground/background layers. The picker header combines the icon with the OneOS name and blue OS accent. ## OS picker | Cover screen | Inner screen | | --- | --- | | Cover-screen OS picker with ColorOS centred and neighboring cards visible | Unfolded OS picker with centred ColorOS artwork | The last selected OS starts centred in the picker. Card scale follows scroll position, selection gives a haptic tick, and the layout adapts when folding. ## Pre-boot checks | Cover screen | Inner screen | | --- | --- | | Cover-screen environment checks with fixed Boot action | Wide environment checks beside ColorOS artwork | Root, storage, battery and screen-lock facts use state tints. The Boot/Update action stays fixed on mobile; scrolling content fades behind it. A pending check shows a native spinner and cannot authorize boot. Artwork transitions connect the picker, setup/update, checks and boot pages. ## Settings and verbose boot | Settings | Experimental options | | --- | --- | | SESL9 settings rows with descriptions outside their cards | Verbose boot switch alongside the VoLTE and camera options | Verbose mode reports observed process events and requested service operations on entry and return. The return frame remains static while no compositor runs, then live status resumes with One UI's compositor. The owner confirmed entry and return working on the Fold8. See [boot status](../boot-status.md) for implementation and guest release-signing requirements.
