vivo X500 / Samsung Galaxy A56 5G (SM-A566B)

Model code listed for China; the manufacturer document gives no other regional code.

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

This record covers the 12 GB model. Usable memory is lower than the label because the system reserves a share.

Usable space is lower than the label because of the system and preinstalled apps.

vivo says 144 Hz applies in gaming scenarios.

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.

Peak values, not sustained brightness.

The manufacturer does not name the front glass.

The 200 mm-equivalent teleconverter is sold separately and is not in the box.

90 W is the charger's maximum output; actual power varies with conditions. The wireless charger is sold separately.

The document gives no power figure.

The hardware supports 6.0; some functions will arrive in a later OTA update.

The headset connection takes digital USB-C headsets only.

NFC-SIM payments work only from the SIM 1 slot.

5G dual-SIM works only with some band combinations and with operator SA/VoNR support.

Actual availability depends on the carrier network and software version.

The 15% larger VC area versus the previous generation is vivo's own claim.

vivo states this is not a professional waterproof phone and that immersion damage is not covered by warranty.

Names in brackets are translations; the vivo China page names the colours in Chinese.

The document gives no update commitment.

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

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

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.

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.

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.
