Samsung’s plans for its upcoming Galaxy S26 series may include a new ultra-slim handset, following mixed reception to the Galaxy S25 Edge. Released in May, the S25 Edge was celebrated for its slim 5.8mm profile, making it the slimmest phone in the Galaxy S lineup. Despite its design appeal, reports suggest that weaker-than-expected sales led to uncertainty about a direct successor. However, recent leaks indicate that Samsung is not abandoning the concept of a slim flagship but is instead preparing a rebranded, even thinner model for the next generation.
According to a post on X (formerly Twitter) by user @SPYGO19726, the device — internally codenamed “More Slim” — could feature a remarkable 5.56mm thickness, surpassing the S25 Edge and even edging past the 5.6mm iPhone Air in slimness. The leak hints that Samsung may be revamping its slim-series strategy, introducing a thinner device under a fresh name rather than continuing the “Edge” branding. This approach could help differentiate the model from previous slim handsets while attracting attention for its innovative design.
The rumored “More Slim” device is expected to sport a 6.6-inch Dynamic AMOLED 2X LTPO 2.5 display with an adaptive 120Hz refresh rate, ensuring smooth visuals without sacrificing energy efficiency. To complement its slim profile, the phone may pack a 4,300mAh lithium polymer battery, slightly larger than the one in the S25 Edge, offering improved endurance despite the reduced thickness. The device is tipped to run on Samsung’s Exynos 2600 chipset, promising flagship-level performance within an ultra-thin chassis.
If these leaks hold true, Samsung could be positioning this new slim model as a standout in the Galaxy S26 lineup — combining cutting-edge design, high refresh-rate display technology, and solid performance. By creating a thinner, rebranded version of the Edge series, Samsung seems to be balancing aesthetic appeal with practical upgrades, potentially appealing to users who value both style and functionality in a premium smartphone.
