Samsung reportedly working on a vertically rollable smartphone

Samsung is reportedly developing a smartphone with a vertically rollable display.

Vertical-rolling Samsung phone?

Front and back design in wide mode

This could give users the flexibility of both wide and tall screen formats in a single device.

According to tipster Ice Universe, the alleged handset can expand from a 16:9 to a 21:9 aspect ratio, allowing users to switch between a conventional smartphone experience and a taller display for immersive viewing.

Unlike previous rollable concepts that expand sideways, Samsung's design reportedly uses a mechanism that extends the screen upward. One of the biggest hurdles, however, could be battery capacity, as the sliding mechanism is expected to occupy a significant amount of internal space.

A few years back, Samsung trademarked the "Galaxy Z Roll" name, hinting at a possible branding option should the device reach the market.

Rollable smartphones are not exactly new. Brands like OPPO and TECNO have previously showcased rollable OLED concepts, but none have made a meaningful commercial debut. I even had the chance to use the OPPO Rollable for a few weeks.

If Samsung succeeds in bringing a rollable phone to consumers, it could become one of the most significant smartphone form-factor innovations in years.
