## Symptom
On Android, content draws under the status bar and navigation bar. `<StatusBar backgroundColor="#fff" translucent={false} />`, `NavigationBar.setBackgroundColorAsync()`, `androidStatusBar.backgroundColor` and `edgeToEdgeEnabled: false` in `app.json` all have no effect. Agents keep adding these props, or React Native's `<SafeAreaView>`, to "fix" the overlap.

## Cause
Android 16 removed the edge-to-edge opt-out. Expo SDK 53 (2025-04-30) enabled edge-to-edge for new projects. SDK 54 (2025-09-10, RN 0.81, targets Android 16 / API 36) enabled it in all Android apps and it cannot be disabled. SDK 55 (2026-02-25) removed `edgeToEdgeEnabled` from app.json, made most expo-navigation-bar methods and the expo-status-bar `backgroundColor` / `translucent` / `networkActivityIndicatorVisible` props no-ops, and deprecated `androidStatusBar` / `androidNavigationBar` in app.json in favour of the expo-status-bar / expo-navigation-bar config plugins. SDK 54 also deprecated React Native's `<SafeAreaView>`.

## Fix
Pad content with safe-area insets instead of colouring the system bars:
```tsx
import { SafeAreaProvider, SafeAreaView } from 'react-native-safe-area-context'

export default function App() {
  return (
    <SafeAreaProvider>
      <SafeAreaView style={{ flex: 1 }} edges={['top', 'bottom']}>
        {/* screens */}
      </SafeAreaView>
    </SafeAreaProvider>
  )
}
```
Or use `useSafeAreaInsets()` to pad specific views. Use `<StatusBar style="dark" />` (icon colour only) and draw your own background behind the bar. Remove `edgeToEdgeEnabled` and the deprecated `androidStatusBar` / `androidNavigationBar` keys from app.json. If you use the `react-native-edge-to-edge` config plugin, install it as a direct dependency (`npx expo install react-native-edge-to-edge`).

## Verify
On an Android 15/16 emulator, headers sit below the status bar and bottom controls sit above the gesture bar, in both light and dark mode.
