 All notable changes to RootADB Pro will be documented in this file.
 
+## [Unreleased]
+
+### Changed
+- Target and compile SDK raised from 34 to 35 (Android 15); Android 15's
+  enforced edge-to-edge is handled by the explicit inset listeners added in
+  this release
+
+### Added
+- Accent color selection now actually themes the app: each accent applies a
+  Material 3 tonal overlay (light + dark palettes) at activity creation
+- "Dynamic" accent option using Material You wallpaper colors (Android 12+)
+- Adaptive launcher icon with monochrome layer for Android 13+ themed icons
+- Predictive back gesture opt-in (Android 13+)
+
+### Fixed
+- Android 12+ light mode no longer renders a near-black background: removed
+  the broken `values-v31` dynamic-color theme that hardcoded
+  `system_neutral1_900` into a DayNight theme
+- Edge-to-edge insets are now handled explicitly (status bar padding on the
+  app bar, navigation-bar padding on scrolling content) instead of relying on
+  `fitsSystemWindows`, surviving Android 15's enforced edge-to-edge and
+  display cutouts
+- Fragment content no longer rests hidden behind the gesture navigation bar
+- Android 8.0 (API 26): navigation bar now uses a translucent scrim since the
+  platform cannot render dark nav-bar icons, keeping buttons visible on light
+  content
+- Orange accent uses a dark on-primary color for WCAG-compliant contrast
+

+# Cross-Version UI/UX Improvements (Android 8.0 → 15+)
+
+**Status:** Complete — all phases implemented; `assembleDebug`, `testDebugUnitTest`, `lintDebug` pass (changes uncommitted)
+**Branch:** PhenixStar/improve-UI-UX-against-all-android-versions
+
+## Problems found
+
+1. `values-v31/themes.xml` hardcodes `system_neutral1_900` (near-black) background into a DayNight theme + `windowLightStatusBar=true` → broken light mode on Android 12+; also kills accent feature on 31+.
+2. Accent color feature is a no-op: pref saved, `recreate()` called, but no theme overlay ever applied.
+3. Edge-to-edge half-wired: decor fitting disabled + transparent bars, but no inset listeners; relies on `fitsSystemWindows` (breaks under Android 15 enforced edge-to-edge); fragment scroll bottoms hidden under gesture nav bar.
+4. API 26: transparent nav bar with no light-nav-icon support → invisible nav buttons in light mode.
+5. No adaptive launcher icon (legacy letterboxed icon on all launchers), no monochrome layer for Android 13+ themed icons.
+6. No predictive back opt-in (Android 13/14+).
+
+## Phases
+
+### Phase 1 — Theme correctness
+- Delete broken `values-v31/themes.xml` base override.
+- Add per-accent `ThemeOverlay` styles (values + values-night, M3 tonal primary/container).
+- `ThemeManager.applyAccent(activity)` applies overlay before `setContentView`; new `DYNAMIC` accent uses `DynamicColors.applyToActivityIfAvailable` (Material You, API 31+, restores intent of deleted v31 file, correctly for both modes).
+- HelpFragment: wire Dynamic button (hidden below API 31).
+- API 26 nav bar scrim set programmatically.
+
+### Phase 2 — Edge-to-edge insets (8.0 → 15+ proof)
+- `util/InsetsExtensions.kt`: status-bar top padding, nav-bar/cutout bottom padding helpers via `ViewCompat`.
+- Remove `fitsSystemWindows` from `activity_main.xml`; pad AppBarLayout top via listener.
+- Fragments: `clipToPadding=false` + bottom inset padding on scroll roots.
+
+### Phase 3 — Launcher icon
+- Adaptive icon (`mipmap-anydpi-v26`) with foreground/background split + monochrome (13+ themed icons). Manifest → `@mipmap/ic_launcher`.
+
+### Phase 4 — Platform behaviors
+- `android:enableOnBackInvokedCallback="true"` (no custom back handling exists — safe).
+
+### Phase 5 — Verify
+- `lintDebug`, `testDebugUnitTest`, `assembleDebug`. Update CHANGELOG.
+
+### Phase 6 — targetSdk 35 (added on user request)
+- compileSdk/targetSdk 34 → 35, manifest tools:targetApi 35.
+- Fixed SDK 35 nullability change: `Bitmap.getConfig()` now nullable (QrCodeGenerator).
+- Behavior review: enforced edge-to-edge covered by Phase 2 insets; FGS specialUse subtype property already present; CONNECTIVITY_ACTION is an exempt system broadcast.
