The regulator ruled that Google had unfairly used its dominance to strongarm device manufacturers and network operators into making sure that traffic on Android devices went to its own search engine.

Google accused European Union antitrust watchdogs of blundering their way through a probe that culminated in a record €4.3 billion ($4.5 billion) fine for allegedly abusing the market power of its Android mobile-phone ecosystem.

Google is squaring off against regulators from the European Commissions today in the EU Court of Justice in Luxembourg.

Google is set to fight for the last time against the big $4.33 billion antitrust fine imposed by the EU in 2018 over its Android business.
