            Samsung Galaxy S25 series is expected to be unveiled at the company's first Galaxy Unpacked 2025 event, which will take place in San Jose, California, on January 22 at 10am PT (10:30 pm IST). The lineup will likely include a base Galaxy S25 model as well as, Plus and Ultra variants. A fourth Samsung Galaxy S25 Slim model is also said to be in the works, and this variant has been spotted on a popular benchmarking website, which suggests its arrival is imminent. The listing hints at the expected chipset, RAM and software details of the phone.
The Samsung Galaxy S25 Slim with the model number SM-S937U was spotted on Geekbench. The handset appears with a motherboard codenamed ‘sun' and an octa-core chipset with six cores clocking at 3.53GHz and two cores at 4.47GHz. This is expected to be the Snapdragon 8 Elite SoC. The phone scored 3,005 and 6,945 points on single-core and multi-core tests, respectively.
The Geekbench listing of the Samsung Galaxy S25 Slim shows the phone with 12GB of RAM and suggests it will run on Android 15, along with the company's One UI 7 interface.
Older reports claimed that Samsung could introduce the Galaxy S25 Slim variant a few months after the release of its flagship Galaxy S25 series, which is expected to comprise base, Plus and Ultra models. A benchmark for the Galaxy S25 Slim variant close to the Galaxy Unpacked 2025 event is a sign that the phone could become the fourth model in the series.
