The iPhone 7's lack of a headphone jack raised eyebrows when it was first revealed, but after several weeks of using the devices many users say it has become a non-issue. Getting rid of the port allowed Apple to increase the size of the battery, improve the phone's vibration feedback and helped make it water resistant.

Samsung may also be able to make the phone thinner than its predecessor by getting rid of the jack. SamMobile also reported that the Galaxy S8 may have stereo speakers to improve the external audio quality.

The site also claims that Samsung will ditch the home button from the S8, with a fingerprint sensor embedded in the display. In combination with the device's curved screen, this could mean the display covering almost the entire front of the device, a design that Apple is reportedly preparing for with its own iPhone 8 next year.

Samsung is in dire need of a successful flagship device to revive its fortunes after the failed launch of the Galaxy Note 7, which was recalled after several units were found to be faulty, leading to explosions.

Mobile World Congress, which runs from February 27, is typically where Samsung unveils new Galaxy S devices.
