The peeps over at sammobile have leaked another build of Android 4.3 for the Samsung Galaxy S4 i9505, the build number on this one is I9505XXUEMJ3. As per sammobile this is one of the final builds and after testing it for 2 days they haven’t found any bugs on this build as well. Also, Samsung should start rolling out Android 4.3 for the Galaxy S4 (i9505 & i9500) within the next 1-2 weeks.
The build date on this build is 8 Oct 2013 and it won’t trip your Knox warranty flag or increase the flash counter so feel free to try it.
