Hover is not necessarily more hidden UI, but could actually go to making bits of phone UI that currently exists more discoverable. A personal gripe of mine is that press-and-hold on a button is a terrible way of discovering something new, you’re never sure if the button is just going to perform its default action (which is something you may not want to do, and without a readily-available “undo” key is kinda dangerous). Hover could go a long way to improving this.
