Ionic Android App working on some devices only and showing only blank screen after splash screen on some other devices

Question

I'm developing an app, I have android devices(Android 9, 10) and emulator to test. Its working fine in my devices and emulators but its not working on client device(Android 9, 10).

My Ionic Info:

Ionic CLI : 6.13.1 (C:\Users\User\AppData\Roaming\npm\node_modules@ionic\cli) Ionic Framework : @ionic/angular 5.6.4 @angular-devkit/build-angular : 0.1101.4 @angular-devkit/schematics : 11.1.4 @angular/cli : 11.1.4 @ionic/angular-toolkit : 3.1.1

Cordova:

Cordova CLI : 10.0.0 Cordova Platforms : 6.0.0, android 8.1.0, browser Cordova Plugins : cordova-plugin-ionic-keyboard 2.2.0, cordova-plugin-ionic-webview 4.2.1, (and 4 other plugins)

cordova-res : 0.15.3 native-run (update available: 1.3.0) : 0.3.0

System:

Android SDK Tools : 26.1.1 (C:\Users\User\AppData\Local\Android\Sdk) NodeJS : v12.16.1 (C:\Program Files\nodejs\node.exe) npm : 6.13.4 OS : Windows 10

Have you tried to debug the issue using chrome://inspect in the chrome browser? — Paresh Gami
Yeah i found a solution by taking a app build under production. (ionic cordova run android --prod) — Theepak

If the screen remains blank (i.e. the app keeps running) it's probably a Javascript error, but just in case, try to run the app with debug configuration and inspect the LogCat messages using Android's SDK DDMS.
