Ionic run android:installed and running on device but cannot touch anything

Hi, I use

ionic start MyIonic2Project tutorial --v2

to start a project and

ionic run android

to install into a device, the app installed and running on device, but all UI components have no touch response, ie: cannot touch anything (my device is android 4.1.2),but it works normally on browser and iOS simulator, does it cause by ionic doesn’t support 4.4 or lower?
