Samsung insider Ice Universe often reveals unreleased Samsung device details. A few hours ago he posted a tweet saying that the Galaxy S10's screen-to-body ratio will be greatly improved. In this case, the only way is to eliminate the border, and the bottom border may be one of the candidate targets to be eliminated. In other words, if Samsung does not intend to copyiPhoneX design.
The Galaxy S9's screen-to-body ratio is currently between 83.6% and 84.2%, which is roughly similar to the Galaxy S8 (83.6% to 84.0%). A leaked picture last year showed the design of the Galaxy S9, which does reveal how Samsung can increase the ratio of screen to body while maintaining the same overall design. So far, we haven't seen any Galaxy S10 schematics or photo leaks, but they will start to surface sooner or later.
