Furthermore, Samsung is maintaining a broad scope for this update. Tests are already underway for the Galaxy S24 and S23 series, as well as the current Galaxy Z Fold 6 and Z Flip 6. The company is even testing it on unreleased models like the Galaxy Z Fold 7 and Z Flip 7. With this latest news, it’s clear that Samsung is dedicated to including its previous-generation foldables in the update cycle.
