The Samsung Galaxy S10 is some way off - in early 2019 - but we're already hearing a bunch of rumours about what form the device will take. 

The Galaxy S9 and Galaxy S9+ were evolutions of the Galaxy S8 and Galaxy S8+ really, so we're expecting big things from a reinvented handset next year.

Some headline features expected include an ultrasonic in-display fingerprint sensor as well as 5G connectivity and a super-sharp display. 

The Samsung Galaxy Note 9 and Galaxy S10 smartphones will be launched earlier in the year than their predecessors, according to a report from the Korea Herald.

The Galaxy S10 meanwhile would be announced in March if it was to follow a similar cycle to the S9, but it's now believed it will be announced as early as January at CES 2019.

Added to this, sources say Samsung may finally introduce its much-rumoured foldable smartphone at Mobile World Congress 2019 in February.

The design is expected to stay relatively similar to Samsung's previous handsets, but expect an edge-to-edge infinity display and no notch - Samsung looks to be staying away from that and it's fast becoming a USP of Samsung handsets as everyone else goes down that route.

There's a good chance that Samsung will shave some millimetres off the bezels, although the rumoured display specs mean the two new phones will be slightly larger than their predecessors. 

Korean website The Bell claims that Samsung's 2019 flagship handset, which will be released as part of the 10th anniversary of the Galaxy range, will go by the name "Beyond" throughout its development process. 

It cites the "parts industry" as the source. It says that the name has been shared with partners already.

We're now know there will be an in-display fingerprint sensor - see below, but it's also been rumoured that there will be a super-sharp display. 

That could mean a pixel density of a staggering 600ppi. At least, that's according to notable Twitter tipster Ice Universe. Ice Universe has been pretty accurate with Samsung leaks in the past.

The Galaxy S9 and S9+ already offer incredibly sharp displays, with 570 and 530ppi respectively, but 600ppi would be an incredible improvement.

The 600ppi will likely be for the smaller S10, whereas the Galaxy S10+ (if there is one) will take a slight dip in density. For Samsung to achieve 600ppi in a similar 5.8-inch screen as the Galaxy S9, the resolution of the display will need to be increased to near 4K quality. 

We're hearing the S10 will once again use Samsung's Infinity Display, but will increase in size ever so slightly, to 5.8-inches (up from 5.77) and 6.3-inches (up from 6.22) for the S10 and S10 Plus respectively. The display design has reportedly been finalised and will go into production in November, however, things can of course change between now and then.

Respected analyst Ming-Chi Kuo said the S10 will come in three different sizes, according to Business Insider. Those three sizes will be 5.8 inches, 6.1 inches, and 6.4 inches.

The larger two S10 models will likely be high-end versions, as they will feature in-display fingerprint sensors, while the smaller model, which will presumably be the entry-level version, will pack a fingerprint sensor on the side.

We're not at all convinced by this as that would mark somewhat of a break in strategy for Samsung. If the three phones did arrive, we guess they probably wouldn't all be available in all territories. 

Could the third phone be the foldable Galaxy X? The rumour mill suggests production of the foldable screen will begin soon. While the Galaxy S10 will be the 10th anniversary for the Galaxy S-series, it will be a separate device to the Galaxy X. 

Ice Universe states that the phone will be a 5G handset and feature a dedicated neural processing chip.

Here's his full, estimated spec list:

  • AI-specific chipset, with CPU, GPU and separate neural processor
  • 5G modem
  • UFS 3.0 storage
  • LPDDR5 RAM
  • 93 per cent or more screen-to-body ratio
  • 9th-generation mobile Super AMOLED display
  • 3D AI processing with camera
  • L-shaped battery

It's a fair bet that the new handset will run Samsung's own TouchWiz interface on top of the forthcoming Android P. It's also likely the next-generation Bixby will be involved as well; we know a new version of the voice assistant will make its debut in the Galaxy Note 9. 

The development of an ultrasonic fingerprint sensor may determine when the Galaxy S10 will be launched.

Korean news site The Bell revealed the Galaxy S10 will finally get an in-display fingerprint sensor, something that was once rumoured for the Galaxy S9 and this has now been confirmed by Samsung itself. A statement from the company said: ""Samsung Electronics has decided to commercialise the display fingerprint reader on the Galaxy S10."

It's reported that the feature will make its way into the Galaxy Note 9 first, although usually reliable industry analyst Ming-Chi Kuo has previously said it still won't be ready for mass-production come the Note 9's release.

The Bell's report also states that Samsung will improve the 3D sensing camera technology in the next S-series flagship to help improve the performance and security of its face unlock feature. It should also result in an improvement for AR Emoji, too. 

It is not currently known if the Samsung Galaxy S10 "Beyond" will also feature 3D sensing Face ID-style technology on the front. Facial recognition tech is big news in the phone market at present but industry sources are yet to establish whether Samsung will use it going forward.

"Unlike FOD, partners in the 3D sensing module are not detecting mass-production movements," one electronics industry source said.

The Bell also claims that as a result of the 3D scanning, Samsung will ditch its iris scanning technology in the Galaxy S10.

A report from South Korea says that Samsung will utilise a new technology that will see the earpiece integrated right into the display - all in order to get the screen to fill the entire front panel of the phone. The report adds that Samsung will use its sound-emitting OLED technology in a 6.2-inch panel, which coincidentally is the size expected for the S10.

The panel will use vibration and bone conduction technology to transmit sound in the 100 - 8000Hz range that can only be heard when pressed to the ear. Read more on this: Samsung may embed earpiece in Galaxy S10 display

Samsung Galaxy S and Note devices are excellent when it comes to their camera departments and the S10 will likely improve further on the S9's already great results.

It's been claimed by Sammobile the 2019 flagship may come with a triple-lens camera, something Huawei introduced on the P20 Pro earlier this year. Details are scarce for now but given Huawei's P20 Pro camera abilities, a triple lens system would be great to see from Samsung.

All About Samsung also believes the rear could have three lenses and the front could have two meaning the device - or, at least, the S10 Plus - could have an incredible five cameras. 

As it says, one possibility is that the Galaxy S10 comes with a main variable-aperture camera (f1.5 / f2.4) which is 12 megapixels and also a super wide angle lens (123-degrees) and 16MP at f1.9.
