TL;DR
An internal Android 17 build leaked details showing a split notification and Quick Settings layout on foldable inner screens, while the outer cover would retain the combined view. The build also includes a long-requested separate mobile data tile and other bug fixes; Google has not yet confirmed when or if these changes will ship.
What happened
Reports based on an internal Android 17 build (codenamed CinnamonBun) suggest Google has continued work on separating the notification shade and Quick Settings panel after related changes first appeared in early Android 16 betas but were omitted from the final release. The leak, attributed to Mystic Leaker, indicates the inner display on foldable devices would always use the split layout: swiping down from the left opens notifications and swiping down from the right brings up Quick Settings. The classic combined panel would still be used on the smaller outer cover display. The same internal build reportedly includes an option to show a separate mobile data tile in Quick Settings so users can toggle cellular data with a single tap. The report notes several visual and functional bugs were addressed in this build. Google has not released the first Android 17 Developer Preview; these interface changes may appear in the initial preview or a later beta.
Why it matters
- A split layout changes basic navigation gestures on larger foldable screens, altering how users access notifications and system controls.
- The move aligns Android’s approach with some vendor skins and other platforms that separate Quick Settings and notifications for larger displays.
- A dedicated mobile data tile simplifies turning cellular data on or off without changing Wi‑Fi settings.
- If enforced on inner foldable displays, the change would reduce user choice compared with a single combined panel.
Key facts
