Ionic 4 android 4.4 does not work

Ionic Framework ionic-v3
1

In the ionic documentation has support for Android 4.4+

But the reality is not quite what it seems … when trying to run a sidemenu app on an android 4.4.4 - 512mb the menu does not work.

I solved the menu by changing the core.

But when navigating between routes the click response time is very slow.
