Samsung's Galaxy range may seem gold-gilded when considering flagships like the Galaxy S20 phones, but there are affordable options too – like the Galaxy A51, which is available with both 4G and 5G connectivity.

Despite its humble specs and performance, the Galaxy A51's premium look and feel, cameras, and smooth user experience quickly made it a favourite among shoppers. In fact, the A51 led global sales in the first quarter of 2020.

With an RRP of £329, it's affordable but still worth a protective case or cover to keep it looking new. Here we round up the best cases and covers around. 

While we haven't tested these options first hand, these brands are ones we trust and have seen in action on other phone models through the years.

Samsung S-View Folio for Galaxy A51

Samsung S-View Folio for Galaxy A51

It would be silly of us not to start with Samsung's own offering for its most popular phone. 

The S-View folio case remains a staple in the manufacturer's original cases. The clever thing about this case, as its name might suggest, is the small window on the front cover that lets you access notifications, calls and other useful information without having to open the case. 

There's even a pocket for you to stow away cards. 

Pick it up from Amazon for £25.99 or directly from Samsung if you're in the US for $49.99.


Spigen Tough Armour for Galaxy A51

With military grade protection, Spigen cases are made to be thrown around – which is why we recommend its products in nearly all our phone case round ups. 

The Tough Armor comes with a built-in stand as well to allow portrait and landscape viewing.

Available on Amazon for £13.99/US$16.99.

Poetic Guardian for Samsung Galaxy A51

Poetic Guardian for Samsung Galaxy A51

Poetic is another favourite of ours for heavy-duty, military-grade protection. It's looks more brutal than Spigen's offering, with its angled-off, shock absorbing corners, but its reinforcement you can trust. It even comes with a built-in screen protector. 

Get it from Amazon for £16.95/US$19.95. US shoppers can pick it up in black (pictured), blue, green or pink.

Tech 21 Studio Colour for Galaxy A51

Tech 21 Studio Colour for Galaxy A51

Tech21's Studio Colour case not only offers 12-foot (3.6m) drop protection, but also anti-microbial protection. Anyone who knows anything about how dirty a phone can get will be glad to have this case on their Galaxy A51 phone. 

(Psst: Here are a few other ways to keep your phone clean).

Apart from protection from bacteria, the other clever feature is that it comes with interchangeable coloured buttons which you can swap out for a flare of personalization.

Pick it up directly from Tech21 for £19.95.

Ringke Fusion-X for Galaxy A51

Ringke Fusion-X for Galaxy A51

Ringke make attractive, tough cases that are also affordable. Raised edges keep scratches at bay while a lanyard hole gives you the option to add a strap if needed. 

It's compatible with wireless charging too. Not bad for £7.99/US$11.99.
