Samsung is reportedly working on a new smartphone with a vertically rollable display. The device could let users switch between two screen aspect ratios, offering more flexibility for different viewing needs.
According to a well-known source, the phone will allow users to expand its display from a standard 16:9 ratio to a wider 21:9 format. This would give users the option to switch between a wider screen and a taller display when needed.
The rumored device is expected to use a sliding mechanism that extends the screen upwards. However, battery capacity could become a major challenge. The internal mechanism may take up considerable space, leaving less room for the battery.
Samsung’s rollable phone plans have surfaced in earlier reports as well. A rumor from June suggested that the company could launch its first rollable smartphone in the first half of 2028. The device could arrive under the Galaxy Z Slide name.
Samsung has also trademarked the Galaxy Z Roll name, which could be another option for the upcoming device. Meanwhile, a patent published earlier this year revealed that the company is exploring a smartphone with a side-rolling display.
Samsung is not the only manufacturer exploring this technology. Vivo is also reportedly developing a smartphone with a vertically rollable screen.
Motorola has already showcased its own approach to the concept. The company presented the Rizr rollable phone at MWC 2023, giving attendees a closer look at how an expandable smartphone display could work.
