Describe the Bug I've built an apk file using the ionic cordova build android --prod --release command. I'm able to successfully install the APK on an Android 5.1.1 Samsung Galaxy Tab (Active). When I start the app up, the splash screen appears but nothing else happens. I'm able to install this same APK on other devices and I'm able to get past the splash screen as expected. One other oddity is that when trying to inspect the device via Chrome Dev Tools, I'm able to Inspect the device but the app code / sources / HTML doesn't load. Nothing happens. So I'm not able to see if there are any errors at this point.

Steps to Reproduce Steps to reproduce the behavior:

1. Create a new prod release apk by running ionic cordova run android --prod --release in your Ionic project
2. Sign the newly created APK
3. Install the APK on a device
4. Tap the app icon to start it up from the app drawer
5. App should load the Splash screen at this point, but it never gets past this screen.

Related Code If you are able to illustrate the bug with an example, please provide a sample application via an online code collaborator such as StackBlitz, or GitHub.

Expected Behavior Upon starting up the app, the Splash screen should appear for 5 seconds before loading up the main screen.

Additional Context I have attempted to debug this via logcat but there isn't much useful here neither. What follows is a capture of what happens when I tap the app icon to start the app up, to the point where the logging output stops.
