Change Splash Screen from Ionic Browser
You have to change
value='screen'
with your own image (like assets/logo.png) in the config.xml file.
You can also change defaults sizes :
<preference name="SplashScreenWidth" value="300" /> <!-- defaults to "170" -->
<preference name="SplashScreenHeight" value="300" /> <!-- defaults to "200" -->
