As John mentioned, the partition not showing up could be UI4 related. If you are willing to send me your lu_sdata, I can look to see what is going on. UI5 has brought a lot of enhancements to the lu_sdata that I use to parse. The next UI5 firmware will allow me to implement 3rd party plugins upon request as it will allow me to retrieve the devicetype to distinguish what type of device it is. One of the reasons why the virtual switch from the app store does not show up.
As for the slider on the tiles, I have researched this in the past and Android has no easy way to prevent from miss firing of the slider when scrolling. In prior releases, I had the option to hide the slider and a tap would reveal it. In 2.0, you can go into settings and have the slider be replaced by on/off buttons and a tap of the tile would reveal the buttons and slider for more refine control. When scrolling I avoid touching near the slider.
