Samsung
Memory and storage—8 GB RAM, 256 GB storage (234.4 GB available); 8/128 and 12/256 GB options depending on market; no microSD slot

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

Samsung
Rear cameras—50MP wide, ƒ/1.8, autofocus and OIS; 12MP ultra-wide, ƒ/2.2; 5MP macro, ƒ/2.4; 10× digital zoom

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.

Samsung
Battery and charging—5,000 mAh (typical); up to 29 hours video playback; 45 W Super Fast Charging 2.0 (adapter sold separately)

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

Samsung
Connectivity—5G Sub-6; Wi-Fi 6 (802.11ax, 2.4/5 GHz); Bluetooth 5.3; NFC; USB-C (USB 2.0); no 3.5 mm headphone jack

Location and sensors—GPS, GLONASS, BeiDou, Galileo, QZSS; in-display fingerprint, accelerometer, gyro, geomagnetic, light and virtual proximity sensor

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

Samsung
Water and dust resistance—IP67 (tested in up to 1 m of fresh water for up to 30 minutes)

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

Samsung

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