Why is the performance of Ionic apps bad on older Android devices? Can this be improved?
Ionic uses the default web browser available in the device to run hybrid applications. The older versions of Android devices use Android’s default browser, which has less performance and compliance as compared to modern browsers.
This can be resolved by using crosswalk with Ionic. Crosswalk will enable you to pack a Chrome webview so that your application is not relying on native Android browser.
