While Samsung has showcased rollable smartphone concepts for a few years, those came from its display manufacturing arm (Samsung Display). Now, the company's mobile division (Samsung MX) may have finally started working on a commercial rollable phone, and the first major detail about the device has leaked.
Galaxy Z Roll could switch between two display aspect ratios
Reliable tipster Ice Universe (@UniverseIce) claims that Samsung has begun developing a phone with a rollable screen that can switch between 16:9 and 21:9 aspect ratios. This means users will be able to toggle the screen format depending on the app they are using or the type of content they are viewing.
A 16:9 aspect ratio is ideal for standard YouTube clips and videos recorded using phones, whereas a 21:9 ratio suits movies, long documents, and web browsing. In its 16:9 form factor, the device should also be more compact and pocket-friendly when not in active use.
However, fitting such a device with a high-capacity battery will be a significant challenge. With rolling mechanism's motors and rails taking up critical room inside the phone, internal space will be even tighter than what we see inside standard foldables.
Earlier rumors suggested Samsung aims to launch its first rollable phone in the first half of 2028. The South Korean tech giant has also previously trademarked the “Galaxy Z Roll” name, which remains the prime candidate for this upcoming form factor.
