Familiar colors and icons with on-screen buttons and a dash of transparency
With a successor to the HTC One on the horizon, we may be looking at our first leak of the purported HTC M8's software. While we only have a single homescreen look to go off of, the first thing that strikes us are the on-screen navigation buttons, giving us a pretty good idea that HTC has scrapped the two-button capacitive setup.
Beyond that, this really looks like a refined version of Sense, with lots of transparency and color dominating the look of the screen. Icons look basically unchanged from the current crop in Sense 5.5, but as we know this could all change. But if this really does turn out to be the new version of Sense on the HTC M8, we can say we wouldn't be upset.
