Would be even more useful if you could extract the apk's and share them, I think? Then those on the 50018 could probably install them or push them into their respective folder locations to test and see?
Q Voice is not new, as it is in the basic 4.2.2, but here it is only in Korean. LG On-screen is also not new, but was not instantly visible either. You could download it from the LG site. The last two are only for Korean cable TV, and are not streaming services, but just TV programming that can be viewed on the tablet, and a remote control.
