Samsung Galaxy A51 5G — Full Specifications, Features & Price in Pakistan

Do not confuse this with the far more common 4G Galaxy A51. The Galaxy A51 5G is a different phone: Samsung's Exynos 980 chip with an integrated 5G modem, a larger 4,500mAh battery, and a quad camera — released in April 2020 as one of Samsung's first affordable 5G phones. In Pakistan's used market it sits in an interesting spot: 5G hardware at a mid-range second-hand price. This guide covers its verified specifications and what the 5G badge actually means for a buyer in 2026.

Design and Build Quality

The A51 5G shares the A51 family's clean design — flat Prism Cube finishes, a centered punch-hole camera, and a rectangular camera block — but it is a physically different phone from the 4G A51: slightly thicker at 8.7 mm and heavier at 187 g to house the bigger battery. The aluminum frame adds rigidity over the all-plastic 4G version. There is no official water-resistance rating.

Display Features

The 6.5-inch Super AMOLED panel at 1080 x 2400 (20:9, ~405 ppi) with Gorilla Glass 3 is a strong point: vivid, high-contrast, and sharp enough that individual pixels disappear. It is a 60Hz panel, so motion is standard rather than silky. For streaming and social media it holds up well in 2026; the main thing you give up versus newer mid-rangers is the 120Hz refresh rate.

Processor and Performance

The Exynos 980 (8 nm) was Samsung's first chip with an integrated 5G modem, pairing two Cortex-A77 performance cores at 2.2 GHz with six efficiency cores and a Mali-G76 MP5 GPU. It is a clear step above the 4G A51's Exynos 9611 — roughly 20–30% more CPU headroom in real terms — and handles daily tasks smoothly. Gaming is mid-range: fine for casual titles, modest settings for demanding ones. The 5G modem is the headline, but note the practical reality below.

RAM and Storage

Sold with 6GB or 8GB of RAM and 128GB of UFS 2.1 storage. The 8GB version is preferable in 2026, but either is workable. Expansion is via microSDXC, though the slot is hybrid — the second SIM and the memory card share one tray, so dual-SIM users must choose between a second line and extra storage.

Camera Features

The quad rear system leads with a 48MP f/2.0 main camera with PDAF, joined by a 12MP f/2.2 ultrawide, a 5MP macro, and a 5MP depth sensor. Daylight shots are detailed and punchy; the ultrawide is genuinely useful. Both front (32MP) and rear cameras record 4K at 30fps with gyro-EIS. Weaknesses: no optical stabilization on any lens, modest low-light performance, and the macro/depth sensors are filler rather than features you will use weekly.

Battery and Charging

The 4,500mAh battery is 500mAh larger than the 4G A51's — a meaningful gain that translated to comfortably full-day endurance when new. On a used unit, check real-world drain. Charging stays at 15W wired, which feels slow today (a full charge takes around two hours). No wireless charging.

Software and Updates

Launched on Android 10, final official software is Android 13 with One UI 5 — two generations newer than the A50 series' endpoint, and recent enough that virtually all current apps still support it. Samsung's security updates for this model have ended, so treat the software as frozen and confirm your essential apps run on the unit you are buying.

Connectivity and Additional Features

5G support covers sub-6GHz bands 41 and 78 (SA/NSA) on the international SM-A516B model, plus full 4G LTE fallback. An honest note for Pakistani buyers: confirm which 5G bands your carrier will use and that this model's band set matches — a 5G badge on the box does not guarantee 5G on your network. Also aboard: dual-band Wi-Fi ac, Bluetooth 5.0, NFC, and full GNSS. Unlike the 4G A51, this 5G version has no 3.5mm headphone jack, so budget for USB-C or Bluetooth audio.

Variants, Colours and Availability

Verified configurations are 128GB storage with 6GB or 8GB RAM, in Prism Cube Black, White, and Pink. The phone is discontinued, so Pakistan stock is second-hand. Because two very different phones share the "A51" name, verify the model number (SM-A516B) on the unit — the 4G A51 (SM-A515F, Exynos 9611, 4,000mAh) is not the same phone and should not command the same price.

Price in Pakistan and PTA Information

The Zohaan Mobile Gallery listed price is Rs. 55,000, verified 2026-10-11. That buys 5G-capable hardware, a 4,500mAh battery, and software that runs Android 13 — a reasonable used-market package at this price. Confirm the current price and the RAM variant with the store before visiting.

Main Advantages and Limitations

Advantages:

• Exynos 980 with integrated 5G — meaningfully faster than the 4G A51's chip
• 4,500mAh battery and quad camera with 4K video on both front and rear
• Android 13 final software — recent enough for current apps
• 6.5-inch AMOLED display; aluminum frame; under-display fingerprint sensor

Limitations:

• No 3.5mm headphone jack (unlike the 4G A51); no IP rating; no optical stabilization
• Slow 15W charging; hybrid SIM slot forces a dual-SIM vs microSD choice
• 5G usefulness in Pakistan depends on carrier bands — verify compatibility
• Security updates have ended; software is frozen at Android 13

Who Should Consider This Phone?

Good fit: buyers who want 5G-ready hardware without paying for a new phone; anyone who found the 4G A51 appealing but wants the faster chip and bigger battery; users keeping phones for years who value the newer software base.

Look elsewhere if: you need a headphone jack, want fast charging, or would rather have 120Hz and IP67 — the Galaxy A52 5G offers those for a step up in price. Browse the Samsung collection to compare.

What is the difference between the Galaxy A51 and A51 5G?

They are different phones: the 5G version uses the Exynos 980 chip (vs Exynos 9611), has a 4,500mAh battery (vs 4,000mAh), an aluminum frame, and no headphone jack. Always check the model number — SM-A516B is the 5G one.

What processor does it use?

The Samsung Exynos 980 (8 nm): octa-core (2x2.2 GHz Cortex-A77 + 6x1.8 GHz Cortex-A55) with Mali-G76 MP5 graphics and an integrated 5G modem.

What are its RAM and storage options?

6GB or 8GB RAM with 128GB storage (UFS 2.1), expandable via microSDXC on a hybrid SIM tray.

Does it support 5G in Pakistan?

The hardware supports sub-6GHz 5G (bands 41/78 on the international model). Whether you get 5G service depends on your carrier's bands and rollout — verify compatibility with your network.

Can it record 4K video?

Yes — 4K at 30fps on both the rear quad camera and the 32MP front camera.

Does it have a headphone jack?

No. The A51 5G dropped the 3.5mm jack found on the 4G A51 — you will need USB-C or Bluetooth audio.

Final Verdict

The Galaxy A51 5G is the thinking buyer's alternative to the common 4G A51: a faster 5G chip, a bigger battery, 4K video, and Android 13 software for Rs. 55,000. Its honest costs are the missing headphone jack, slow 15W charging, and 5G that depends on carrier reality in Pakistan. Verify the SM-A516B model number on the unit, check the battery, confirm the IMEI, and it is a solid upper-mid-range used pick.
