Samsung is preparing to launch its Galaxy S25 series, which also includes a new addition to the lineup – the Galaxy S25 Slim. Along with the regular Galaxy S25, Galaxy S25+ and the top-end Galaxy S25 Ultra, the Galaxy S25 Slim is expected to come out with a thinner and more compact design. While we wait for Samsung’s official announcement at the Galaxy Unpacked event, which is rumored to take place on January 22, 2025, a new leak sheds light on what makes the Galaxy S25 Slim unique.

Reportedly, the Galaxy S25 Slim may use Samsung’s latest ALoP (all lenses on prism) technology for its telephoto camera. This technology was recently announced by Samsung Semiconductor and promises to make smartphones thinner without compromising image quality. According to tipster Jukanlosarewe on

So, what exactly is ALoP? In simple terms, this is a clever design for telephoto cameras that helps reduce the size of the camera module. Traditional telephoto cameras use curved optics, which can be bulky and create large camera bulges on the back of the phone. ALOP solves this by placing the telephoto lens in a flat position with the plane of the phone and using a 40-degree tilted prism with a 10-degree tilted sensor. This setup not only reduces the length of the camera by about 22 percent compared to older designs but is also capable of capturing sharper photos.

Thanks to ALoP technology, the Galaxy S25 Slim can have a much smaller camera bump while maintaining great zoom capabilities. The phone is rumored to include a periscope telephoto lens with 3.5x optical zoom, a 200-megapixel ISOCELL HP5 main sensor, and a 50-megapixel ultra-wide camera. This is impressive for a device that is rumored to come with a 6.66-inch display.

Interestingly, it looks like the Galaxy S25 Slim will have some features that the standard Galaxy S25 and Galaxy S25+ won’t even include, like an upgraded telephoto camera. However, all four models of the lineup are expected to launch at the same time, with rumors suggesting pre-orders will begin on January 24, 2025, and sales will begin on February 4, 2025. We’ll have to wait for Samsung’s official reveal to know for sure what the Galaxy S25 Slim coming in January will actually be like.
