Hi there,

Thanks for opening an issue with us! Would you be able to provide a repository with the code necessary to reproduce this issue?

Android 4.4 ships with an older version of Chromium that is not upgradeable and not exactly the same as Chrome for Android. That being said, Ionic has been fully tested and supports the following mobile platforms (including Android 4.4): https://ionicframework.com/docs/intro/browser-support#mobile

If you are still experiencing issues, I recommend that you enable polyfills in your polyfills.ts file: https://angular.io/guide/browser-support#polyfills

Thanks for using Ionic!
