People have always been able to customize their Android devices to suit their preferences. That includes personalizing the design, installing any apps they want and choosing which services to use as defaults in apps like Google Chrome.
Following the changes we made to comply with the European Commission’s ruling last year, we’ll start presenting new screens to Android users in Europe with an option to download search apps and browsers.
These new screens will be displayed the first time a user opens Google Play after receiving an upcoming update. Two screens will surface: one for search apps and another for browsers, each containing a total of five apps, including any that are already installed. Apps that are not already installed on the device will be included based on their popularity and shown in a random order.
