Does the increasingly larger secondary screen really make the Galaxy Z Flip more convenient, or is it just a design change to create differences between generations?
At the Galaxy Unpacked event taking place on July 22, 2026, Samsung Electronics officially introduced Galaxy Z Flip8 and a new generation of folding phones. One of the points that Samsung continues to develop is the FlexWindow secondary screen, which has changed significantly since the first Galaxy Z Flip series.
Observing the development process of the Galaxy Z Flip line shows that Samsung has shifted from a secondary screen that only serves to view notifications to a space that can run applications, quickly control and support Galaxy AI features. This is a trend of upgrading throughout many generations instead of just focusing on hardware configuration.
Generation Secondary screen characteristics
Galaxy Z Flip The small screen mainly displays the time and notifications
Galaxy Z Flip3 Design is significantly larger, displaying many widgets
Galaxy Z Flip4 Continues to optimize interface and usability
Galaxy Z Flip5 FlexWindow almost covers the entire upper half of the body, supporting more applications
Galaxy Z Flip6 Continue to improve software and integrate AI
Galaxy Z Flip7 Design is more nearly borderless, optimizing the outside experience
Galaxy Z Flip8 FlexWindow continues to be upgraded in terms of interface and operationsSimilar to the main screen and deeply integrated with Galaxy AI as announced by Samsung on July 22, 2026.
Notable changes
* Display area increased sharply compared to the first generation.
* The ability to run applications on the secondary screen is increasingly improving.
* The interface is designed to be consistent with the main screen.
* New Galaxy AI and One UI help you perform multiple tasks without turning on the device.
Significance of this trend
Samsung is turning the secondary screen from a notification display area into an independent screen for daily operations such as replying to messages, taking selfies, controlling music, viewing calendars, making payments and quickly opening applications. This helps reduce the number of times you have to open the phone, while also taking advantage of the clamshell design of the phone.
It should be noted that the composite image circulating online is only illustrative of the process of design change between generations.
