Thanks to two separate reports this week, we have learnt some exciting new details about the upcoming Samsung Galaxy S10 - one of the smartphone highlights to come in 2019.

New details revealed this week include how there are expected to be three versions of the Android handset, called the S10 Lite, S10, and S10+.

It has also been claimed that the smartphones will be revealed by Samsung at one of the company's Unpacked media events on February 20, ahead of the Mobile World Congress technology show in Barcelona. After this, the phones will reportedly go on sale on March 8.

This is according to a source speaking to Gizmodo. They elaborated to say that the Lite version of the S10 will have a flat screen - something Samsung hasn't had on any of its Galaxy S flagships for several years. Meanwhile, the other two models will have screens which curve at their edges, just like this year's Galaxy S9.

Offering the flat (and presumably cheaper) model is an interesting move from Samsung, which could see the brand's flagship series become more affordable. We suspect the regular S10 and larger S10+ will cost from around $1,000, so the S10 Lite could offer a strong alternative to the iPhone XR, which starts at $749.

It is said that the flat Galaxy S10 will have a 5.8-inch display (the same as the iPhone XS), while the regular S10 will measure 6.1 inches and the S10+'s size isn't known for now. However the Gizmodo report, which comes from the UK, claims the flagship S10+ will get 1TB (1,000GB) of storage, and cost a staggering £1,399 ($1,800).

The same source, who is said to have verified their identity, also claims the Galaxy S10 trio will feature Samsung's new Infinity O display, which made its debut on the A8S this week. Instead of housing the front-facing camera and other sensors in a display 'notch' - as seen on the iPhone XS and most other flagship smartphones from 2018 - Samsung sits the camera in a small circular hole in the upper-corner of the screen.

This takes up a little less space than a notch, giving more display real estate for the operating system.

Another claimed feature, called Powershare, will allow the Galaxy S10 to be charged wirelessly, but also top up the batteries of other smartphones held against its back - just like the Huawei Mate 20 Pro does.

As for biometric security, the Samsung Galaxy S10 is claimed to have an in-display fingerprint reader which uses ultrasonic technology to read your print through the glass front of the phone. This should be a more secure option than the optical in-display readers used by other manufacturers, where light is bounced off your finger to take a photo of the print pattern and unlock the phone.

Also this week, Twitter user Ice Universe, who has a strong track record for Samsung leaks, shed some light on the S10's camera arrangement. They say the S10 Lite will have one on the front and two on the back, while the S10 gets one on the front and three on the back, and the S10+ gets two on the front and three on the back.

This tallies with images tweeted by fellow smartphone leaker Evan Blass, who says a case manufacturer expects the S10 trio to look like this:

With just a couple of months to go until the expected reveal, we can expect plenty more leaks and rumors to emerge, so stay tuned for those. In the meantime, will you be buying a Samsung Galaxy S10? And what feature of the new phone are you most excited about? Let us know in the comments below.
