You can try building with `--prod`  
It does work for me.

See another post about the same issue.

> Hello. I’ve updated my app to use ionic v2 RC4 today, and when I’ve run the app on my Android device, the app’s loading time has increased a bit in comparison with the previous ionic 2 version. Now, after the splashscreen fades, the app still spends about 2 seconds more in a blank screen before showing the app. Is anyone else experiencing this issue? Any advice about what can I do?
