Samsung Galaxy A56 5G (SM-A566B) / Samsung Galaxy S23+ (SM-S916B)

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.

The refresh rate varies between 48 and 120 Hz depending on content; the lower rate on static screens saves battery. Vision Booster adjusts contrast and colour to keep the screen readable in bright light. The size is measured as a full rectangle; the viewable area is smaller because of the rounded corners and camera hole.

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

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

Samsung introduced this version as a Snapdragon optimised for Galaxy and exclusive to the S23 series at launch.

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

Available storage is lower because of preloaded software; there is no memory card slot.

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.

The telephoto gives 3x optical zoom; zoom beyond that is digital. According to Samsung the wide camera records 8K video at 30 fps.

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

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

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

Wi‑Fi 6E needs a router that supports 6 GHz; band availability varies by market and operator.

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.

According to Samsung, the S23 series was the first S series to use Victus 2.

The typical value is the average of battery samples measured by a third-party lab under IEC 61960; the rated value is the minimum capacity.

45 W needs a 5 A cable; the adapter is sold separately. Wired charging is compatible with QC2.0 and AFC, wireless with WPC. PowerShare needs more than 30% battery to charge another device. The S23 is limited to 25 W.

Samsung promised four Android upgrades and five years of security updates for the S23 series; timing varies by model and market.

Samsung does not advise beach or pool use.
