Right now the plugin uses custom 'www/img/splashscreen.png' image which is different from the system splash screen image defined in manifest file - 'images/splashscreen.png'.
There are the following problems due to this:
1. you first see system splash screen image and them custom one image. - they could be different
2. We have pull requests to update system splash screen images. Since the plugin uses custom images that feature won't work.
Solution is to use system splash screen image image defined in application manifest.
