According to the Wall Street Journal, the next phone in the series will come with 5G support, and an impressive 6.7-inch display (Note 9 is 6.4 inches).
The latest gossip surrounding the S10 comes after reports of the South Korean conglomerate launching a trio of Galaxy S10 models.
The tech giant could be set to follow rival Apple's lead by developing three versions of the devices, and it is looking to release a 5G version in the US.
As reported by Bloomberg, the standard edition - codenamed 'Beyond' - will be around the same size as the 5.8-inch S9 model, with triple cameras at the back and a front camera under the screen.
The OLED screen will seemingly be curved on both sides with rounded corners and essentially no bezel at the top or bottom, while the report adds that there will also be a fingerprint sensor under the display.
It's said the company wants to match Apple's XS Max and budget XR iPhone models with a larger 'Plus' version, and a cheaper device without the dual-curve edge screen or sensor.
Meanwhile, Samsung - who have apparently codenamed its foldable phone 'Winner' - is reportedly in talks with Verizon to release the S10 with a 5G-capable chipset in the US.
