### Ionic Framework Version
v8.x
### Current Behavior
After making any code change (e.g., adding a simple
Clearing the app's cache (Settings > Apps > [App] > Storage > Clear Cache) fixes it temporarily, and the app works until the next rebuild. This does not happen on other Android 14 devices (e.g., Samsung, Pixel) or emulators.
Logcat shows WebView initialization issues before cache clear: failed APK opens for Trichrome library, "Entry not found", odex loading failures, and DNS/HTTP cache warnings. After cache clear, WebView loads cleanly, and Capacitor bridge starts successfully.
### Expected Behavior
The app should load and render normally after any rebuild/install, without requiring manual cache clearing. WebView should initialize consistently across devices.
### Steps to Reproduce
Create a new Ionic Angular tabs starter app: ionic start test-blank tabs --type=angular --capacitor.
Make a minor change, e.g., in src/app/explore-container/explore-container.component.html, add
Build and sync: ionic build && npx cap sync android.
Open in Android Studio, build, and install APK on a Ulefone Android 14 device.
Launch the app → blank white screen.
Clear app cache → app works.
