The HTC One M8 for Windows brings many 'firsts' to the table, including support for the 801 chipset, duo camera and more. One of those originals is the ability to hide the Nav bar aka where the Start, Search and Back key reside. On previous Windows Phones these keys were part of the device, so that when the display is off they were still visible. Now with Windows Phone 8.1, manufacturers get the ability to use on-screen keys instead, cutting down costs and letting companies like HTC port over their Android phones with no change in the hardware.
Although phones like the Nokia Lumia 630 have on-screen keys, the HTC One for Windows adds a few options to the mix, including an auto-hide option. Here's how it all works.
