Apple iPhone 17 / Samsung Galaxy A56 5G (SM-A566B)

ProMotion adjusts the refresh rate to the content: 120 Hz smoothness when scrolling, lower rates on still images to save battery. The Always-On display shows the time and notifications dimmed while locked. Because of the rounded corners, the visible area is slightly smaller than the rectangle measurement.

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.

3,000 nits is a short peak in strong sunlight, not sustained full-screen brightness. The 1-nit minimum aims to avoid eye strain in a dark room. The screen has anti-reflective and oleophobic coatings.

According to Apple, the colour-infused back glass is used on Black, Mist Blue, Sage and Lavender.

Apple notes that this resistance is not permanent, may decline with normal wear, and that liquid damage is not covered by the warranty.

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

The GPU supports hardware-accelerated ray tracing; the Neural Accelerators speed up AI work inside the GPU.

There is no memory card slot.

The 2× image comes from the centre of the 48 MP main sensor rather than a separate telephoto lens; the optical-quality zoom range is 4× in total, with digital zoom up to 10×. The ultra wide camera also takes 48 MP macro photos.

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.

Dual Capture records with the front and rear cameras at the same time. Action mode strongly stabilises footage shot while walking or running.

Center Stage automatically adjusts the framing to the people in photos and video calls; the TrueDepth system for Face ID works with this camera.

25 W wireless charging needs a 30 W or higher adapter; no adapter is included. Battery life varies with Apple’s test conditions, network and settings.

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

Wired data transfer is limited to USB 2 speed, so moving large video files takes time. USB-C can output to an external display at up to 4K HDR.

Thread provides low-power mesh connectivity with smart-home devices. Ultra Wideband helps locate devices such as AirTag by direction and distance; availability varies by country.

Emergency SOS and Roadside Assistance via satellite are offered depending on country; Crash Detection is included.

The Action button can be set to functions such as silent mode, torch, translate or a shortcut. Camera Control is a touch-sensitive button that adjusts exposure, depth and zoom by sliding.

No power adapter or EarPods are included.

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.

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

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

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

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

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.
