Samsung’s upcoming Galaxy S27 flagship lineup, slated for an early 2027 debut, will feature four models codenamed NM1 through NM4, bringing significant camera and battery capacity upgrades led by a new 50MP ultrawide Sony IMX855 sensor and potential lithium-ion cell expansions.
With the release of the Galaxy Z Fold 8 series behind it, Samsung is shifting focus toward its next generation of non-folding flagships. Import and export data and industry reports reveal that the tech giant’s upcoming smartphone family will consist of four distinct devices, mimicking Apple’s strategy of offering two base units alongside two high-end flagships. These models carry the internal codenames NM1, NM2, NM3, and NM4, with the prefix standing for New Miracle
or Next Miracle
as part of a generational naming shift from the previous M-series codenames.
Internal Codenames and the Arrival of the Galaxy S27 Pro
The lineup introduces a brand-new model tier to sit between the standard devices and the top-tier Ultra. According to reports detailed by WinFuture, the NM1 corresponds to the standard Galaxy S27, while the NM2 represents the Galaxy S27+. Capping off the portfolio is the NM4, which very likely refers to the Galaxy S27 Ultra.
This structural expansion addresses market demands for a high-end experience in a more compact form factor.
Camera Hardware Overhauls on the Pro and Ultra Models
Photography changes form the core of the early hardware leaks. The Galaxy S27 Pro and Galaxy S27 Ultra are reported to share a 50MP ultrawide camera powered by Sony’s IMX855 1/2.55-inch type sensor. This identical ultrawide hardware is also found on the recently introduced Galaxy Z Fold 8 Ultra, signaling component sharing across Samsung’s high-end portfolio.
For front-facing photography, both top-tier devices will employ a 16MP selfie camera equipped with autofocus. At least the S27 Pro’s front shooter is slated to receive optical image stabilization, though confirmation on whether the Ultra variant will match this OIS addition remains pending.
Zoom and Telephoto Configuration Differences
Telephoto capabilities create a distinct boundary between the S27 Pro and the Ultra. The S27 Pro and S27 Ultra share a primary zoom lens featuring a 50MP sensor with OIS and 5x optical zoom. However, the Ultra model is reported to house a second telephoto camera, utilizing part names R1 and R2, while the Pro model is not expected to feature a secondary zoom sensor.
Meanwhile, the base Galaxy S27 and Galaxy S27+ are currently in testing with a new 50MP main camera utilizing a Sony sensor alongside OIS. Despite using its own proprietary camera sensors, Samsung is testing external options early in the development cycle, though these tests do not strictly guarantee final inclusion. The base models will retain a 12MP ultrawide lens identical to that found on the Galaxy S26 and S26+.
Battery Capacity Leaps and Lithium-Ion Strategy
Power supply developments suggest a significant break from past stagnation. Leaks indicate that Samsung is testing significantly larger battery options for the Galaxy S27 Ultra, sourcing new battery cells from Samsung SDI in the 5,600mAh to 5,800mAh range. If testing proceeds without issue, the Ultra could launch with more than 5,500mAh inside.
This adjustment would break the Ultra series’ long-standing plateau at 5,000mAh, which persisted from the S20 Ultra through the S26 Ultra. While competitors look toward silicon-carbon battery technology to pack dense power into slimmer chassis, Samsung is reportedly doubling down on traditional lithium-ion chemistry with enhanced efficiency and physical scaling.
Launch Timeline and What Remains Uncertain
The entire Galaxy S27 family is expected to officially launch in early 2027, following historical release cadences. While hardware specs for the upper models are materializing through import data and internal testing leaks, exact configurations for the base models’ telephoto cameras and the Ultra’s primary camera remain subject to verification as development continues.
