From the reports of the Investor, Samsung recently renews its licence agreement to keep Google Search pre-installed on its Devices. In the Terms, it states that Samsung will receive a fee which will depend on earnings from Google advertisements.
Earlier in this week, it has revealed that Google will pay $3 Billion to Apple to remain default search engine on its devices. We know that Samsung sells more devices than Apple so ad revenue will be more and that’s why the licensing fee too.
Based on the estimates Google will have to pay around $3.5 Billion in licensing fee this year.
