From the leaked snaps below we are seeing that BlinkFeed can now be easily turned on and off, which was impossible in Sense 5.0, which is a very welcome change. Those camera improvements we heard about are now materializing in the form of two more options like Panorama+ and Dual Capture. Panorama+ might very well be a 360 degrees mode, while Dual Capture would be snapping with both the front and rear cameras at once.
The notification toggles drop down menu has received a new "Do Not Disturb" option, and there are some new Emoji and rescaling options in the on-screen keyboard. All in all, nothing groundbreaking, but some welcome changes nonetheless.
