Samsung Galaxy S10 Plus appears in leaked video, giving best look yet at new smartphone

Full specs of Samsung's new smartphone were also revealed

A leaked video has surfaced online that appears to show a plus-sized version of the Samsung Galaxy S10, less than one week ahead of its official unveiling.

The 30-second video reveals key features of the flagship smartphone, such as its in-screen fingerprint scanner and dual-lens front-facing camera.

Previous leaks suggest that Samsung will include the innovative selfie cam in the Samsung Galaxy S10 Plus – one of three versions of the Galaxy S10 that the South Korean tech giant is planning to launch next week.

The other two devices are a standard Galaxy S10 and an entry-level Galaxy S10e, both of which are expected to feature a single lens on the front of the phone.

The tenth anniversary edition of Samsung's S-series of Galaxy smartphones is also shown to include a hole-punch design to accomodate front-facing technology while maximising screen size.

Samsung is set to unveil the new Galaxy devices at its Unpacked event on 20 February, though numerous leaks mean there may be little left to reveal.

Other gadgets expected to be announced incude a foldable phone called the Galaxy X and a new smartwatch called the Samsung Galaxy Watch.

The latest leak comes courtesy of Mobile Fun, who claim to have received the video from "extensive contacts in China".

A separate leak appears to have confirmed all the specs for each Galaxy S10 device.

According to documents seen by GSM Arena, only the two higher-end models will feature an in-screen fingerprint scanner. The Galaxy S10e will instead keep its biometric security feature on the side of the device.

The screen sizes will range from 5.8" for the Galaxy S10e, 6.1" for the Galaxy S10 and 6.3" for the Galaxy S10 Plus.

Samsung does not comment on rumours surrounding its unreleased smartphones.
