Description

Creating an ImageBackground with a blurRadius is just not reliable enough to use in production. Sometimes it works on physical devices, sometimes it does not and the prop. is ignored completely. On my iPhone SE and iPhone 8 it never works, but on my iPhone 5s it sometimes works (I may have to reload a few times).

Reproducible Demo

render(){ 
     return (
      <ImageBackground blurRadius={10} source={require("./stallsky.jpg")} style={{width: "100%", height: "100%"}}> . 
      </ImageBackground>
    }
}

Works perfectly on the simulator, does not work reliably on devices. Hard to test because it's so unreliable.

I am noticing this on Android too.
It works perfectly in debug mode, but fails in release mode.

We have the same issue but only on iOS devices. On Android, it works consistently, but on iOS it is a hit and miss. It does work in the emulator

UPDATE

I got resolved by cloning project again actually the image from the assets are not being copied to ios folder that's why its happening
