(Pocket-lint) - Samsung has officially unveiled its 2021 flagship, the new Galaxy S21 series. There are three phones in the new line-up, the Samsung Galaxy S21, the Galaxy S21+ and the Galaxy S21 Ultra.

Here's everything you need to know about the first two of those devices, the Galaxy S21 and S21+. We have covered the Galaxy S21 Ultra in a separate feature.

Release date and price

  • 14 January launch
  • Available from 29 January 
  • Galaxy S21: from £769/€849
  • Galaxy S21+: from £949/€1049


Samsung usually announces the Galaxy S range of smartphones in February, moved Galaxy Unpacked to 14 January, making for an earlier launch in 2021. That will see the new devices on general sale from 29 January, with pre-orders opening immediately.

The pricing for the Galaxy S21 and S21+ have also dropped a little from 2020, so these phones are now a little cheaper. The Samsung Galaxy S21 will start from £769 in the UK, while the Galaxy S21+ will cost from £949 in the UK.

  • S20: 151.7 x 71.2 x 7.9mm, 172g
  • S21+: 161.55 x 75.6 x 7.86mm, 202g
  • IP68 waterproofing

There's a couple of big design changes for the Galaxy S21 models. The most noticable thing is the shift from curved edges to the display on previous Galaxy S models, to a flat display, giving a slightly different look to the front of this phone. Around the back of the phone, you'll find that the camera housing is now integrated with teh frame, so it's more of a feature on the back.

Otherwise, much of the design sticks to the familiar from previous Galaxy S phones, with waterproofing to protect the devices to an IP68 level. There's no 3.5mm headphone socket, but the stereo speakers remain.



  • S21: 6.2in, FHD+
  • S21+: 6.7in, FHD+
  • Adaptive refresh rate 48-120Hz
  • HDR10+ support

We've mentioned that the display will be flat on these devices, unlike the Ultra which retains the curves to the edges. There's also a shift in the resolution with both getting a Full HD+ resolution. That's also a change of direction of Samsung, which previous put a Quad HD+ display in all its flagship devices. That's not likely to make a huge difference to the S21 with the smaller display, but means that the larger S21+ won't be able to produce as much fine detail. 

That probably won't matter: Full HD+ is the default resolution on Samsung devices and we suspect that many have never bothered to switch to Quad HD+ settings when that option was available. What is important, is that these displays will now support adaptive refresh rates, with a range of 48-120Hz being available. That will allow the device to pick the best option for the content that's being displayed, balancing battery life with performance. 

As this is an AMOLED we'd expect the bright and vibrant performance that we've seen before from Samsung.

Hardware and specs

  • Exynos 2100 or Qualcomm Snapdragon 888, 5G
  • 8GB RAM; 128GB/256GB storage options
  • S21: 4000mAh battery
  • S21 Plus: 4800mAh battery

The Samsung Galaxy S21 and S21+ will be powered by the Exynos 2100 in some regions and the recently-announced Qualcomm Snapdragon 888 in others.

Samsung's Exynos 2100 is expected to close the performance gap with the Snapdragon hardware, so there might be less of a difference in these devices in 2021.

There will be 128GB and 256GB storage options, while both will come with 8GB RAM. It looks as though that's going to be the only option, but there may be regional differences.

In terms of battery capacities, the Galaxy S21+ will have a bump to 4800mAh, while the S21 will come with a 4000mAh capacity.


  • Triple camera system
    • Main camera: 12-megapixel, 1.8µm pixel size, f/1.8 aperture, OIS
    • Telephoto: 64MP, (3x optical / 30x digital zoom) 0.8µm, f/2.0, OIS
    • Ultra-wide: 12MP, 1.4µm, f/2.2
  • Selfie: 10MP, 1.22µm, f/2.2

Both the Galaxy S21 and S21+ will come with a triple rear camera made up of a 12-megapixel main sensor, 12-megapixel ultra-wide sensor, and a 64-megapixel telephoto sensor - the same overall selection as the Galaxy S20 models. 

Most of the changes will come in the software, with the addition of a Director's View, Vlogger View and the ability to take 8K stills from 8K video. You'll be able to shoot 4K 60fps on all the cameras. Additions to Single Take will provide moer options, while there will be AI-powered boosts to portrait modes with more options.

Overall, we'd expect the performance of both these devices to be the same when it comes to the camera - and we don't expect it to be hugely different to the S20.
