Splashscreen not showing on android device (just once !)

When I “run android”, the app shows my splascreen when it gets started by ionic.
Once installed on the device, I get a black screen at start.
I had ‘ionic resources’, all the screens are in the android/res folder.
Here is my config.xml :

<feature name="Device">
    <param name="android-package" value="org.apache.cordova.device.Device" />
</feature>
<feature name="SplashScreen">
    <param name="android-package" value="org.apache.cordova.splashscreen.SplashScreen" />
    <param name="onload" value="true" />
</feature>
<feature name="StatusBar">
    <param name="android-package" value="org.apache.cordova.statusbar.StatusBar" />
    <param name="onload" value="true" />
</feature>
<feature name="Whitelist">
    <param name="android-package" value="org.apache.cordova.whitelist.WhitelistPlugin" />
    <param name="onload" value="true" />
</feature>
<feature name="Keyboard">
    <param name="android-package" value="io.ionic.keyboard.IonicKeyboard" />
    <param name="onload" value="true" />
</feature>

What I can’t understand is why the spashscreen shows just once?
