Design: It may maintain a similar foldable design to previous iterations but with a more robust and streamlined structure. If a beige version is available, it would offer consumers more personalized aesthetic choices.
Display: The Z Fold4 could potentially have an even larger, more dynamic, and brighter foldable AMOLED screen with higher refresh rates for a smoother viewing experience.
Processor: It would likely feature the most advanced Qualcomm Snapdragon processor available at the time of its release for more efficient performance.
Camera: The camera system could be significantly improved, potentially with advanced AI-driven features for better photo and video capture.
Battery: The battery life could be improved for more extended use and potentially feature even faster charging technology.
Software: It would presumably run on the latest Android operating system, with improved multitasking features that take full advantage of the foldable design.
5G: It would undoubtedly continue to support 5G connectivity.
Again, this is conjecture based on trends seen in smartphone development as of 2021. For the most accurate information, I would recommend checking Samsung's official website or contacting their customer service.
