Samsung Galaxy S25 Ultra / Samsung Galaxy A56 5G (SM-A566B)

The Samsung Newsroom release is dated 23 January Korea time; the event was 22 January in US time.

Samsung notes memory options may vary by market and usable storage is lower because of preloaded software. There is no card slot.

With no card slot, storage cannot be expanded later, so the capacity choice matters for heavy photo and video use.

Samsung quotes 40% NPU, 37% CPU and 30% GPU gains over the previous generation. This version is tuned for Galaxy with higher clocks than the standard Snapdragon 8 Elite.

Samsung says a larger vapor chamber than the previous generation spreads heat better in games and multitasking.

The vapor chamber spreads heat from the chip into the body, helping clocks hold longer in extended gaming.

The viewable area is smaller than the diagonal because of rounded corners and the camera hole. Refresh that drops to 1 Hz saves power on static content; Vision Booster adjusts tone mapping in bright light.

120 Hz makes scrolling smoother; 1,200 nits is reached in High Brightness Mode, which switches on automatically in sunlight. Allowing for the rounded corners, the visible area is 6.5 inches.

Used on the front only. Corning says it survived drops of up to 2.2 m onto a concrete-like surface in internal lab tests; this is not a durability guarantee for any given phone.

Titanium is used only on the frame, excluding the volume and side keys.

Per Samsung, 3× and 5× are optical; 2× and 10× are “optical quality” zoom made by sensor cropping. OIS is optical image stabilisation.

Optical stabilisation (OIS) is on the main camera only and reduces shake at night and in video. There is no telephoto camera; zoom is digital.

Log records a flat profile for colour grading; results depend on the editing workflow. Audio Eraser can reduce layers such as voices, music, wind and crowd separately in videos.

The 45 W adapter is sold separately. Samsung quotes up to 31 hours of video playback. Wireless PowerShare charges earbuds or a watch from the back of the phone.

45 W speeds need a 45 W USB PD PPS adapter; lower-powered adapters take longer.

According to Android Central’s one-year report, the phone received One UI 8 (Android 16) ahead of schedule.

5G/LTE availability depends on market and carrier.

USB 2.0 is slower than USB 3 ports for large video transfers and has no video output.

Water resistance is not permanent and may diminish over time.

Colour availability varies by country and carrier.

Glass on the back as well is uncommon in this class; Samsung notes the camera lens covers are not included.

4K recording is limited to 30 fps; smoother video needs a drop to 1080p.

A virtual proximity sensor uses software and other sensors rather than dedicated hardware to turn the screen off during calls.

This is no guarantee against seawater, pool water or pressurised water.

This is the longest support yet in the Galaxy A series; rollout timing can vary by country and carrier.

Knox Vault stores sensitive data such as PINs and passwords in an isolated hardware area separate from the main processor.
