Found solution. Problem was in cordova-plugin-android-permissions. On android 6+ (maybe android 5 too, I don’t have it on my devices) user should accept permissions manually. In application permissions request looks like alert view. And this alert automatically stops splashscreen (even if you don’t hide splashscreen automatically and don’t call hide method yet) and broke fade out animation. Also this permissions request broke splashscreen even if permissions already added.
So solution is to request permissions after splashScreen.hide() after timeout delay equal to fade out timeout.
