Small developers may be winners after a judge's ruling in the long legal battle between Epic Games and Google. The tech giant must allow consumers more choices on its app store.

A federal judge has ordered Google to tear down the digital walls shielding its Android app store from competition.

Google has been ordered to open up its app store to rivals following a major court case in the US. Last year, a federal judge ruled the tech giant was running an illegal monopoly in how it controlled the distribution of apps on its Android operating system and via the Google Play Store.
