Thru an OTA update. Now running Sense 6 on version 4.09.401.3, Android version 4.4.2. Just updated (493 M Improvements - - Speed, definitely an improvement in the UI response. - The Sense 6 custom screen is bigger, better and more customizable - Fonts have changed, so have the widgets (more flat surfaced, better and compact looking). - It apparently brings something that's called Extreme power saver, still have to see how much of an improvement is it. Cheerios!
Indeed. Does feel like an extension to an extremely capable phone. Now to hunt for a battery case for it
The other improvements that I noticed are with the Camera settings and options. Swiping on the screen changes cameras (rear or front facing). There are more settings to play with - ISO can be set from 400-1600 There are 9 modes of shooting with Text and Sweep Panorama added. Filters can be selected from the screen itself. Profiles can be customized and saved.
