Splash screen image exists and is properly sized

A missing or undersized splash screen causes two distinct failures: App Store binary rejection (both stores validate that the referenced file exists and meets minimum dimensions) and a jarring white flash during app cold start on devices where the OS cannot scale a too-small image. Expo's required minimum of 1080×1920 matches the baseline 9:16 device ratio; dropping below that introduces pixelation on any mid-range or flagship device. Apple's HIG (apple-hig-launch-screen) and Android's splash screen API (android-splash-screen) both require a launch image to prevent a blank white screen during initialization — omitting it degrades the perceived startup performance that store review teams actively evaluate.

Create a 1080×1920 splash image and wire it in app.json. The resizeMode should be contain (not cover) to prevent cropping on non-standard aspect ratios.

// app.json
{
  "expo": {
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    }
  }
}

For bare React Native iOS, add a LaunchScreen.storyboard in Xcode that references the image. For Android, place a drawable in android/app/src/main/res/drawable/launch_screen.xml. Confirm the file physically exists at the declared path before submitting — a broken reference causes silent build failure in EAS.

• ID: mobile-store-readiness.visual-assets.splash-screen-configured
• Severity: high
• What to look for: Check app.json for splash field with image property. Count all splash screen configuration files found across platforms. Verify the image file exists at the path specified. For Expo, the recommended size is 1080x1920 (9:16 ratio). For React Native, check for splash screen configuration in ios/[AppName]/LaunchScreen.storyboard or android/app/src/main/res/drawable/launch_screen.xml.
• Pass criteria: Splash screen image exists, is referenced correctly in config, and uses a minimum size of at least 1080x1920 pixels or equivalent aspect ratio. The splash.image path in app.json must resolve to an actual file. Report: "Splash screen at path X with configured resizeMode Y."
• Fail criteria: No splash screen image found, path in config is broken, or image size is below 1080x1920 pixels (e.g., 480x640 or smaller). Do NOT pass when a splash config exists in app.json but the image file is missing at the referenced path.
• Skip (N/A) when: Never — splash screen is required for app store submission.
• Detail on fail: Specify the issue. Example: "No splash image found at path specified in app.json: assets/splash.png" or "Splash image dimensions are 600x800 — recommended 1080x1920 to prevent pixelation on high-DPI devices"
• Remediation: A splash screen displays during app startup while code initializes. Create or provide a splash screen:
  1. Design a 1080x1920 image (portrait orientation, 9:16 ratio) that matches your app's branding
  2. In Expo (app.json):

     "splash": {
       "image": "./assets/splash.png",
       "resizeMode": "contain",
       "backgroundColor": "#ffffff"
     }
     

  3. For React Native iOS, add a storyboard file or static image set
  4. For React Native Android, add a drawable XML or static image in res/drawable/
  5. Use vector graphics (SVG) where possible for better scaling
