The Galaxy A51 is a nicely specified handset that should appeal to Samsung fans looking for mid-range performance at a reasonable price. There are more affordable alternatives if you’re interested in buying SIM free, though.
My review sample came from Vodafone, where it’s on contract from £34 a month. It is only available in black from Vodafone, but white, blue and silver versions are available direct from Samsung, where the handset will set you back £329 (inc. VAT) SIM free.
For that money you get 128GB of internal storage, of which 21GB is used out of the box and 107GB is free for your own use. You can augment this via a MicroSD card without sacrificing one of the Galaxy A51’s two SIM slots. There is just 4GB of RAM, although 6GB is becoming increasingly common, even at the lower end of the market. The Galaxy A51 runs on Samsung’s Exynos 9611 processor and turned in respectable Geekbench 5 benchmarks, with average scores of 346 (single core) and 1321 (multi core). That’s a shade under the benchmarks for the Motorola Moto G8, and Google Pixel 4a, but perfectly respectable for a handset at this price.
The Galaxy A51’s 4000mAh battery kept the handset going for 11 hours and one minute under the PC Mark for Android Work 2.0 battery test, and when asked to play YouTube video for three hours non-stop at full screen, it dropped 20% from a full charge.
In short, this is a handset that should be up to most everyday tasks, and as long as you don’t push the battery too hard, you should get a day’s use from it.
The Galaxy A51 is quite thin at 7.9mm (it’s 158.5mm tall and 73.6mm wide), and weighs just 172g. It has a 3.5mm headset jack at the bottom, but the most impressive feature in design terms is the backplate. This has a couple of angled insets so that the design is a mix of two-tone plain design and vertical stripes. But even more interesting, the back refracts light in a true rainbow effect, which is really eye-catching. However, without a case it’s a slippery critter.
The 6.5-inch AMOLED screen delivers bright, punchy images, and its 2,400-by-1,080 pixel resolution (405ppi) means that text is readable and graphics look pretty sharp. There are small side and top bezels, and a slightly larger bottom bezel, making for a decent screen-to-body ratio of 87.4%. A punch-hole for the front camera sits in the top centre of the screen. The fingerprint sensor is in-screen, and Gorilla Glass 3 provides some protection against drops.
The quad camera setup at the rear is impressive for a handset at this price point. The main 48MP f/2.0 wide-angle camera is joined by 12MP f/2.2 ultra-wide-angle (123°), 5MP f/2.4 macro and 5MP f/2.2 depth sensing cameras. Images were pretty impressive, and I did enjoy using the macro lens. It’s a shame this is hidden away under the More button on the main screen, where it sits with pro mode, panorama, food, night, slow-mo, super-slow-mo, and hyperlapse modes. The selfie camera is a 32MP unit with an f/2.2 wide-angle lens.
Android 10 is coupled with Samsung’s own UI and quite a lot of pre-installed extras, including Samsung Pay, Netflix, Facebook, Instagram, Spotify and Samsung’s own Galaxy Store. Some of these can be deleted, but anything else you don’t want will need to be hidden away in a folder somewhere.
For those on a budget, Samsung’s Galaxy A51 performs capably, has a large screen, strong battery life and looks good. It’s worth shopping around at this price though, as there’s plenty of competition.
