In its loss to Epic Games in court, Google has just a few weeks to implement some massive changes in the Play Store and Android.

A US federal court ruled Thursday that Google must open its Android operating system to rival app stores, after the internet giant lost an appeal in an antitrust case filed by Fortnite maker Epic Games.

A Ninth Circuit ruling this week sides in favor of Epic Games, allowing its Android app store to be placed within the Google Play Store. It's been reported that Google will seemingly seek an appeal, potentially through the "full Ninth Circuit first.
