Is there an option to install updates as a background process without user intervention?
The reason I ask that is that my HTC One updated to 4.3 today and in the Software Update page it has a tickbox saying "Auto Update." I know it's not a Note 3 but this wasn't there in 4.2.2 so I wonder if this option is in 4.3 across all platforms.
It seems odd that a Cloud WAP should suddenly report the error where it has never done so before. I would venture that it was the catalyst rather than the reason. Do you have any Knox processes running, irrespective of whether you have touched the Knox app at all? If so, have you tried stopping, clearing and disabling them, then ticking 'Unknown Sources?' Although you won't know if it works for 28 days of course
Most peculiar.
