What is Google Discover on Galaxy S21?
Google Discover is a rebranded Google Feed for mobile devices. You can get customized contents from various sources.
It is more than the news service. Google Discover also offers evergreen contests based on your browsing history and interest. Videos and visual contents are also included.
Of course, it does not include your calendar events or schedules on the page. So, you will feel the Discover page less intrusive.
You can consider Google Discover as an extended version of Google News with additional interest-based evergreen contents.
