There’s a white-blank screen in android, just before the launch screen, at the start of the Application, that white-blank screen it’s about 2 seconds in devices like Samsung j1 with android 5.1. That 2 seconds it’s due to the app performance or the Android and hardware performance, that 2 seconds can be reduced?.
We make up the problem using the following in our app theme:
<item name="android:windowDisablePreview">true</item>, that means that the white screen now it’s transparent, so it seems to be an Android problem from the user perspective, but it’s a way to reduce the time of this preview screen to a half or near zero?
Reference to this problem in:
- Android – Disable dummy starting window of application
- blank screen comes before splash

This will tell you where the time is being spent during startup and give you suggestions on how to improve that.
Also, you can provide a splash screen that shows instead of the white screen. See details here:
