Have you tried replacing the JavaScript Core with the one from the react-native-community repository? https://github.com/react-community/jsc-android-buildscript

  The downside with those is that the build of JavaScriptCore is significantly bigger than the one React Native currently ships with. It's quite a big dependency to have in an app, and a shame Google doesn't expose the system V8 runtime on Android in the same way Apple does with JavaScriptCore on iOS.

    Android stopped having a system V8 runtime several years ago. Ever since all webviews you use are just frames to a normal app that's updated over the normal app stores.

      Right, but you can use the system webview that way... so why not also use the V8 engine embedded inside the system webview?
