(Pocket-lint) - Samsung typically announces two flagship smartphone series every year - the Galaxy S and the Galaxy Note - with the former launching in the first half of the year and the latter in the second half. 

With the Galaxy Note 20 officially unveiled on 5 August, all heads have now turned to the next Galaxy S, which could be called the Galaxy S21 or the Galaxy S30.

This is everything we have heard so far about what we can expect for the Samsung Galaxy S21 and S21+ smartphones. We've covered the Galaxy S21 Ultra in a separate feature.

What will the next Samsung Galaxy S be called?

  • Likely Galaxy S21, S21+
  • Galaxy S30 is possible

Before the Samsung Galaxy S20 arrived, the naming strategy for Samsung's Galaxy S devices was easy to predict as the company followed sequential numbers. 

After Samsung jumped from the Galaxy S10 to the Galaxy S20 in 2020 however, it's now harder to determine what the next Galaxy S will be called going forward. We would put our money on the Galaxy S21, Galaxy S21+ and Galaxy S21 Ultra as this would tie in with the year too, but the company could also use Galaxy S30.

For now, Samsung has not confirmed the name for the next Galaxy S device but as most rumours call it the Galaxy S21, that's what we will refer to it in this feature until there is any substantial evidence suggesting otherwise.

Release date and price

  • Early 2021 launch
  • Likely on sale from March 2021

Samsung usually announces the Galaxy S range of smartphones in February, followed by a March release so we would expect the same for 2021, though there have been reports suggesting the devices might arrive in January 2021.

The Samsung Galaxy S9 was announced on 25 February and on sale from 16 March. The Galaxy S10 was announced on 20 February and on sale from 8 March and the Galaxy S20 was announced on 11 February and on sale from 6 March.

If the company doesn't break with tradition, we'd expect to see the Galaxy S21 series go on sale either on 5 March or 12 March, but we're just taking an educated guess for now.

In terms of price, we'd expect the devices to be in a similar ballpark to their predecessors, with the Galaxy S21 the cheapest and the Galaxy S21 Ultra - if there is one - the flagship device. 


  • Glass or plastic and metal premium design
  • Drastic redesign unlikely

The Samsung Galaxy S20 series made a few changes on the design front compared to the S10 series (ignoring the S10 Lite), moving the camera housing on the rear from the centre to the left corner.

The front remained largely unchanged however with a punch hole camera in the centre of the display at the top. It's not yet clear if Samsung will change the design drastically from the Galaxy S20 - we expect to see some changes but we don't expect to see an entire redesign.

A waterproof body with a glass rear and metal frame are likely to remain for the Galaxy S21 with new colour options, though a plastic body has also been mentioned for the S21. The colours are reported to be grey, pink, violet and white for the Galaxy S21, and black, silver, and violet with pink for the Galaxy S21+. Not all regions will get all colours - it's likely that some of these colours will only be available in Korea.

The biggest change might come if Samsung succeeds in offering an under-display front camera but there's only one rumour to say this is a possibility so far.


  • Three sizes again?
  • 120Hz refresh rates
  • Curved edges
  • 1400nits peak brightness

The Samsung Galaxy S20 has a 6.2-inch display and the S20+ has a 6.7-inch display. Both have curved edges and a Quad HD+ resolution with a 120Hz refresh rate.

It's said the display sizes will remain the same for the Galaxy S21 and S21+, though a drop to a Full HD+ resolution has been claimed. The 120Hz refresh rate is expected again however, and both displays are reported to come with a peak brightness of 1400nits.

We'd also expect curved displays, at least on the S21+.

Hardware and specs

  • Exynos 991/992 or 1000/Qualcomm Snapdragon 875, 5G
  • 128GB/256GB storage options
  • S21 Plus: 4800mAh battery
  • S21 Ultra: 5000mAh battery

It is currently unclear what chipsets will power the standard Galaxy S21 and S21+ but the Exynos 2100 has been suggested, along with the unannounced Qualcomm Snapdragon 875. Samsung's Exynos 2100 should be the successor to the Exynos 990.

It's also been claimed there will be 5G variants of both devices and they will be offered in 128GB and 256GB storage options. 

In terms of battery capacities, the S21 Ultra is likely to have the largest, followed by the S21+ and then S21. Early leaks suggest that the Galaxy S21+ will have a bump to 4800mAh, while the S21 is said to come with a 4000mAh capacity.


  • Under-display front camera?
  • 108MP main camera rumoured
  • OIS on front camera?

Samsung will be looking to boost the offering of the cameras for the S20 models.

It's been claimed that both the 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.

Additional camera features have also been claimed for the S21 models, including the cameras automatically switching between 30fps and 60fps depending on the lighting conditions, a dual recording mode, improved night mode, more manual controls and improved moon mode.
