Ever since moving to a phone with virtual navigation buttons, I’ve been bugged by the screen space they use—a gripe held by many out there as well. However you minimize this issue, be it a mod that reduces the height of the navigation bar, using Pie control on Paranoid Android or CM10, or a third-party app such as Button Savior, there’s now an alternative called the Ultimate Dynamic Navbar, developed by XDA Forum Member MrBIMC.
Ultimate Dynamic Navbar is possibly the one solution that many have been waiting for. Instead of drastically changing the way we navigate our devices with a different UI and position, it retains the navigation bar in its form and shape, with one subtle twist: It can hide itself. What’s even better is the extensive customization that MrBIMC has allowed for, packing in four different themes, the option to adjust transparency, and a choice of three activation methods, among plenty of other settings. Additional buttons can be set, and different actions can be triggered on long-press. The app also includes the option to hide the real navigation bar, thus a rooted device is required.
Ultimate Dynamic Navbar is actively supported by MrBIMC, with an agenda of ridding bugs and including even more customization options such as theming support. This support can already be seen with the seven versions already under his belt. The app is ad-free and is free exclusively on the XDA Forums.
