The two new devices are the Lumia 930 and Lumia 630, and apparently they do not come with the ability to change the default search engine from Google.
While this seems to happen on these two new Windows Phone 8.1 devices once they are out of their respective box, current owners of Nokia Lumia mobile devices that update them on Windows Phone 8.1 are able to change their engine default search and highlight Google.
Interestingly, some European versions of smartphones allow users to select Google as default search engine for searching online, without that Microsoft would make comments on the issue.
In the past, the Lumia devices always arrived with the search engine Bing by default, which was not surprising since it is owned by Microsoft, but you can choose to set Google as default search Internet Explorer, which is apparently not possible on these devices.
Google has been scrutinized in the past, and is currently the subject of an antitrust lawsuit, which states that Google requires manufacturers of Android smartphones to use Google as default search engine, even if they allow you to change one for Bing, Yahoo, Ask and others.
This marks a new episode in the war of search engines to gain market share desktop and mobile . Google and Apple allow users on Android and iOS respectively, to choose their default search engine on their devices. However, Apple is probably also interested in removing Google on its screens such as Microsoft can be, although the company will find a competitor, such as Yahoo or Bing.
