Samsung readies custom modem and eye-friendly display technology for the Galaxy S27 line

Samsung is planning key internal upgrades for its upcoming Galaxy S27 flagship lineup, including a custom cellular modem and revamped display tech. South Korean outlet The Elec reports that Exynos variants of the Galaxy S27 will feature an in-house M2700 modem built on a 4nm manufacturing process. Meanwhile, circulating supply-chain rumors suggest the series could also introduce an optional DC dimming mode for its screens. [1][2]

The 4nm M2700 external modem is expected to bring faster data speeds and improved power efficiency over the Exynos Modem 5410 found in some Galaxy S26 units. On the visual front, the addition of DC dimming would let users adjust brightness through voltage regulation rather than low-frequency pulse-width modulation (PWM). While PWM preserves low-light image uniformity and reduces manufacturing costs, it frequently causes eye strain, headaches, and nausea for sensitive users. [1][2]

These hardware shifts tackle long-standing criticisms of Samsung's flagship devices. A more capable in-house modem could narrow the performance divide between regional Exynos and Snapdragon models, while adopting DC dimming would offer a rare alternative to standard OLED flicker, matching features currently seen on rival flagships like the Motorola Signature 27.
