Overview: This report analyzes Samsung's Galaxy Z Fold7 performance in the US. The Z Fold7 became the first book-style foldable smartphone to claim the monthly top-selling spot among devices powered by Snapdragon in the US for August 2025. While the Z Flip4 became the first foldable in the top-selling spot in August and September of 2022, this new feat is impressive, as book-style foldables are not subsidized entirely like clamshell devices. It is still early, but the Galaxy Z Fold7 may serve as an inflection point for book-style foldable adoption in the US, given its early success.
