Samsung made waves when it launched the Galaxy S21 line, comprising the Galaxy S21, S21+ and S21 Ultra.

They're all striking and attractive phones, especially with that new wraparound camera bump drawing the eye,

Thin and lightweight

This is a great choice if you want a slim case.

Pros
  • Super thin
  • Decent protection
  • Shows off your phone
Cons
  • Not the most drop-proof

but they're also pricey items that you'll probably want to be pretty careful with.

If you're looking to pick up one of these ex-flagships mobiles, you'll want a case to go with it and here we've gathered a selection of the best available for you.

Samsung Smart Clear View Cover with S Pen

Folio excellence

A nice, simple but elegant folio case.

Pros
  • Useful window
  • Looks great
  • Pen holder
Cons
  • A bit bulky

If you're going full-bore and getting the Galaxy S21 Ultra, this might just be the ideal case - it incorporates some of the phone's smartest features, and has the space to hold the Galaxy S Pen, which unlocks so much potential.

You get solid protection and a window through which the display will show key information, plus a stylish, understated look.

This is the simplest possible case for the S21 - Samsung's own official plastic sleeve gives it a thin, almost impossible-to-see layer of protection.

That means it won't do a huge amount to protect from big drops, but it makes a difference on the scratching front, without impacting on the design of the phone much at all, while letting your choice of colour shine through.

Cloth coating

We love the cloth finish on this clever case from Samsung.

Pros
  • Nice cloth finish
  • More solid case
Cons
  • Won't be to everyone's taste

If you want a more substantial case, and fancy an interesting texture to grip onto, this official case from Samsung could be perfect.

It returns from the S20 lineup to bring a textured, fabric finish to your case, with a delightful herringbone-ish pattern that's really easy on the eye. For now, it's one of the most stylish options available.

A great see-through case as an alternative.

Pros
  • Great clear option
  • Affordable
  • Good drop protection
Cons
  • Not the most interesting

There are multiple options out there if you're looking for a clear case, and another great one is offered up by Speck in the form of the Presidio Perfect Clear. Its cases aren't all see-through but are all really protective and sleek.

Still, we love the Perfect Clear most of all, for how smoothly and nicely it protects the S21 without bumping up its profile by much at all. 13-foot drop protection means that it still brings a really impressive amount of armour on board, though.

Gear4 Copenhagen

Classy and subtle

This is a classy, subtle case that we're taken with.

Pros
  • Nice and slim
  • Recycled material
  • Good protection
Cons
  • Arguably a little muted

If you want to be conscious of the environment as you make your choice, you could do a lot worse than this case from Gear4, which is the first ever case to be made with recycled D3O plant-based material. It's a great step forward, but also looks really excellent.

The subtly textured finish on the back of the phone makes it easy to hold, and 13-foot drop protection means it's solid where it counts.
