Just read on SearchEngineLand that google has officially launched infinite scrolling with in-app searches on ios and android.

If you don't have the update, go into the app store and update your google app to see results for yourself.
Here are screenshots from one phone that had the update and another that did not. The difference can be found in the "More Results" vs "Next Page" button and the eventual endless scroll.
