I have used Samsung now for around 6 years. In general they are pretty good all round and the A51 is no exception. It has a great screen, a good camera system and easy, solid operating system. Battery life is a bit average (may be the Covidsafe app!) but I am overall happy with the phone. Unfortunately there is a serious gremlin in the fingerprint scanner where it plain refuses to read one or more fingers, yet a few minutes later it works perfectly. I took the first A51 back to the dealer reasoning I had a dud, but this one is just as bad. Hopefully something Samsung can fix with a software upgrade.

A mid-range phone that doesn't justify its price

Sluggish performance

The Samsung Galaxy A51 looks great on first impressions, but extended usage reveals some frustrating shortcomings. Read all about it in our full review.

“Samsung's Galaxy A51 has the best display at this price.”

Modern design; Excellent display; Good photos with enough light; Good battery life; A headphone jack

Lackluster performance; Slower fingerprint sensor; Won't receive OS updates quickly

At $400, Samsung's Galaxy A51 has a gorgeous display, good cameras, and a battery that will easily get you through the day, but it can use a boost in the processor department.

Excellent display; Solid cameras; Good battery life

Underwhelming performance; Not waterproof; Fingerprint sensor doesn’t work well

While the original Galaxy A50 offered an incredible value for the money last year and sold in the millions across the globe, the new Galaxy A51 is a very slight upgrade that doesn’t offer much reason for an upgrade and doesn’t impress that much.

Beautiful AMOLED screen; Long-lasting battery life; Elegant thin design

Stuttery performance with slightly more challenging tasks; Mediocre camera

The A51 proves Samsung can make solid mid-range phones. Its flagship-esque design and solid cameras provide the foundations for an excellent handset, while One UI provides an excellent user experience. However, performance is less than impressive, while the poor in-display fingerprint scanner is a big letdown. Samsung fans can look beyond these shortcomings, but at this price point the A51 is hard to recommend.

2020 might just go down in history as the year of the midrange smartphone. Apple's new $399 iPhone SE is our highest-rated non-flagship model in some time, and we're expecting about a dozen or so more similarly priced offerings to hit US carriers this year. First up is the $399.99 Samsung Galaxy A51. It offers plenty of value for its price in the form of a handsome design, long battery life, good camera quality, and a gorgeous display. But it's no competitor to the iPhone SE in the power department.Design, Display, and Durability Put simply, the Galaxy A51 looks good. It measures 6.24 by 2.90 by 0.31 inches (HWD) and comes in at 6.06 ounces. It’s light and just narrow enough to hold and use in one hand without any big issues. In the US it’s available in black with an attractive prismatic finish. In other parts of the world there are blue and white options available as well. The front of phone is dominated by a near bezel-less 6.5-inch AMOLED display with a 20:9 aspect ratio and a...

Samsung’s Galaxy A51 packs a great screen, a handful of cameras, and a big battery -- what more could you ask from a mid-range smartphone? Well, more consistent performance, for one.

Excellent design; Big and beautiful AMOLED screen; Flexible multi-camera system

Laggy performance; Camera quality is largely unremarkable; Mediocre battery life
