About the Samsung Galaxy A51 5G
The Galaxy A51 5G was Samsung's move to make 5G ordinary rather than a flagship luxury. It took the hugely popular A51 formula and swapped in an Exynos 980 chip with a built-in 5G modem, so mid-range buyers got network speeds that had previously been reserved for the S series. What carried the phone was the screen: a 6.5-inch Super AMOLED panel with proper contrast and deep blacks, which is still noticeably better than the LCDs used by budget rivals. Samsung also kept the practical touches, including a 3.5mm headphone jack and a microSD slot alongside the 128GB of built-in storage. The compromises show up elsewhere. The display runs at a standard 60Hz, charging tops out at a leisurely 15W, and the quad camera leans on 5MP macro and depth sensors that add little beyond a longer spec list. There is no official water resistance rating either. Its Android update window has now closed, so this is a phone for light use rather than a long-term daily driver.

Frequently asked questions
Is the Samsung Galaxy A51 5G worth buying?
It stacks up as a cheap way into a Super AMOLED screen and 5G, but only for light or secondary use. Samsung's three generations of Android upgrades have been delivered and the phone no longer receives new Android versions or security patches, which matters if you bank on it.
Does the Samsung Galaxy A51 5G work on all UK 5G networks?
Yes. The Exynos 980 has an integrated sub-6GHz 5G modem, which is the type of 5G every UK operator uses. No UK network runs consumer mmWave, so nothing is missing in practice.
How does the Samsung Galaxy A51 5G compare to the Galaxy A52 5G?
The A52 5G is a clear upgrade. It moves to a 120Hz Super AMOLED panel, adds IP67 water and dust resistance and stereo speakers, upgrades the main camera to 64MP with optical stabilisation, and charges at 25W instead of 15W. Screen size and battery capacity stay the same.
Does the Samsung Galaxy A51 5G have a headphone jack and microSD slot?
Yes to both. There is a 3.5mm headphone jack and a microSD slot that supports cards up to 1TB, on top of the 128GB of built-in storage. That combination has disappeared from most Samsung phones since.
Is the Samsung Galaxy A51 5G camera good?
It is fine in daylight and unremarkable elsewhere. The 48MP main camera and 12MP ultrawide handle everyday shots well enough, while the 5MP macro and 5MP depth sensors add little. The 32MP front camera is one of the stronger parts of the setup.
Is the Samsung Galaxy A51 5G waterproof?
No. The A51 5G carries no official IP water or dust resistance rating, so treat splashes with care and keep it away from submersion. Samsung added IP67 protection from the Galaxy A52 5G onwards.

Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality. Where DXOMARK has lab-tested the phone, its measured score replaces this estimate.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
