Screenshots and videos of HTC One (M8) running Android 5.0.1 with Sense 6.0 made the rounds online. This time, the device boots software number 4.1 as opposed to 4.0 from a past leak. Unsurprisingly, the Sense-d Android 5.0 on the HTC One (M8) looks fresh yet familiar. The Recents view is almost stock Android-like, while the Notification area and the Quick Settings are, in terms of design, a fusion between the language seen in Google's Lollipop and HTC Sense. The new OS version should arrive on the Taiwanese company's flagship smartphone in the near future. HTC promised to update the One (M8) to Android 5.0 by February 2, 2015. Source...
