Latest Samsung Galaxy S26 Rumors for December 2025

Samsung is preparing for 2026: will the new series manage to combine technological breakthroughs with aesthetic lightness? A comprehensive overview of rumors and leaked information.

Thinner than iPhone 17 and Visual Changes

As we approach the beginning of 2026, the aesthetics of the Galaxy S26 series are increasingly being discussed behind the scenes of technology. While a radical form revolution is not expected, the latest sketches indicate that Samsung aims to take the crown of the “thinnest flagship.” Leaked data (e.g., from Ice Universe) suggests that the base S26 model could be just 6.9 mm thick, which is noticeably less than the anticipated competitor iPhone 17 casing.
There is also discussion about the evolution of the camera block. While Samsung has long promoted a “hanging” lens design, some sources analyzing the One UI 8.5 code hint at a possible return to a unified, slightly protruding camera island or a new lens arrangement reminiscent of the Fold series aesthetics. This would provide the phones with cohesion and better protect the optics.

M14 OLED — Efficiency vs. Brightness

Is it really brighter?

One of the biggest expectations is the use of next-generation M14 OLED materials. This technology, supplied by Samsung Display to other manufacturers, boasts 20–30% greater energy efficiency and longer lifespan.
However, recent reports indicate that Samsung may choose a conservative path: instead of a blind race for nits (which already reach ~2600), the company may focus on battery saving. It is likely that the Ultra model will receive exclusive technology without a polarizer (“Color-filter-on-encapsulation”), which will further improve outdoor visibility and reduce energy consumption, but base models may remain with similar brightness parameters as S25.

Return of the 2-nanometer Exynos and Qualcomm Dominance

Exynos 2600 Bets

The biggest intrigue revolves around the processors. For Europe and parts of the Asian market, Samsung is preparing the Exynos 2600 (codename “Thetis”). This is expected to be the first mass-produced chip built using the advanced 2 nm (SF2) technology process. Additionally, it is anticipated that it will integrate a proprietary GPU solution, replacing the previous AMD graphics.

Global Distribution

Despite Exynos ambitions, the US and Chinese markets, as well as the Galaxy S26 Ultra model worldwide, are likely to remain loyal to Qualcomm and use the Snapdragon 8 Elite Gen 5. This creates a dual situation: the 2 nm technology promises incredible efficiency, but yield rates still pose challenges, so the final regional distribution may vary.

Software Power Instead of Megapixel Wars

It seems that Samsung is halting the megapixel wars. In base models, the main sensor will remain at 50 MP, but it may be upgraded to a newer 1/1.56″ format sensor for better dynamic range.
In the Ultra model, the biggest news is expected not in the main 200 MP camera, but in the zoom area. While previous rumors about 324 MP sensors have quieted, the most realistic scenario is an updated 3x telephoto lens with higher resolution (possibly 50 MP) or improved optics ensuring smoother transitions between zoom levels. 4K 120fps video recording capabilities are also expected across all lenses.

Preparing for a Quantum Future

To ensure longevity, Samsung is integrating protections against future threats into the Knox platform. The anticipated implementation of Post-Quantum Cryptography (PQC) standard will protect user data even with the emergence of powerful quantum computers capable of “breaking” current encryptions. This is particularly relevant for business clients and those planning to use the phone for 5–7 years.

Galaxy S26 vs. iPhone 17 and Pixel 10

2026 will be a year of fierce competition. The iPhone 17 promises to finally implement 120 Hz displays (“ProMotion”) across all models, thus eliminating one of Samsung’s key advantages in the base segment. However, the Galaxy S26 should maintain leadership in optical zoom (even base models have a dedicated 3x lens, which the base iPhone lacks) and in an open AI ecosystem.
