You are not using lazy loading right?

Have you maybe an annotation @IonicPage() in your about.ts, contact.ts, home.ts, tabs.ts etc.? Maybe try to remove them

@reedrichards - There was one, have removed it, still same issue. I m using below command.

ionic cordova run android --prod --release

Have you maybe some remaining page.module.ts (like about.module.ts) files?

If you are not using lazy loading, delete them (except of course app.module.ts)
