Another day, another bunch of leaks have emerged revealing more information about the upcoming Samsung Galaxy S20 smartphone.

This time, XDA Developers reports that the new handset will have a display with a 120Hz refresh rate, which means it will move far smoothly than the 60Hz rate of its Galaxy S10 predecessor. Users will be able to pick between the two refresh rates in the settings app, as the higher 120Hz option will use more battery life.

It is also claimed the new Samsung will have a slightly unusual display shape, with a ratio of 20:9 and a resolution of 3200 x 1440. This means the screen will be a little taller than on the S10, making it seem narrower.

The report claims all three versions of the phone - called the S20, S20+ and S20 Ultra - will come with the tall-and-narrow screen shape. Even at a claimed 6.9 inches, this narrower design means the largest Galaxy S20 Ultra shouldn't be too difficult for most users to hold comfortably.

An under-display ultrasonic fingerprint sensor is also confirmed for the Galaxy S20 range, although this shouldn't come as a surprise, as it also featured on the S10 family from a year ago.

Something not coming to the Galaxy S20, at least according to XDA Developers, is a headphone jack. This would be the first time Samsung has omitted the port from its flagship Galaxy S range, but given rivals like the iPhone haven't offered one for several years, we're not too shocked by this development.

Other leaked specifications include the ability to shoot 8K video, albeit only at a rather limiting 30 frames per second. A more sensible option to record 4K video at 60FPS and with stabilization will also be offered, and the flagship S20 Ultra is claimed to boast a huge 108-megapixel main image sensor.

Sticking with the camera system, it is claimed the phone will have a new feature called Smart Selfie Angle, where the system recognizes when you are trying to cram more people into the frame, then switches to a wide-angle selfie camera.

Samsung is hosting a launch event on February 11, where the S20 family and a new folding handset called the Galaxy Z Flip are expected to be revealed, along with an update to the company's Galaxy Buds wireless earphones.
