You may have heard that the European Union punished Google with a record $5.1 billion fine on Wednesday for abusing its power in the mobile phone market.

Specifically, the authorities dinged Google on its practices with Android, the mobile operating system that the company provides to makers of devices. The size of the fine and the remedies that regulators ordered Google to make were consequential, both symbolically and in how handset manufacturers may incorporate Android into mobile devices in Europe in the future.

But what does that mean for you if you own an Android phone? Here’s a rundown.

What’s the problem?

Android is one of the most prevalent mobile operating systems, used in 80 percent of the world’s smartphones.

Google freely provides the Android operating system to third-party handset makers. As part of the arrangement, Google requires Android phone makers to pre-install 11 Google apps on their phones. That strategy has helped Google’s signature products — search, maps, Gmail and the Chrome internet browser among them — reach more than one billion people.
