Let me share with you something toooootally strange that happened to me today on UE75NU7102. This TV also does not have "transfer channel list" in the antenna expert menu, which I hate but have to live with it as Samsung doesn't care (I will never buy Samsung again).
But to the story:
Yesterday while browsing through the USB disk with movies my tv suddenly poped up a message that there is no storage space left on the tv and it recommends the "factory reset" to free up space. I guess some cache regarding settings/netflix/spotify/web-browser and usb content must have eaten the tv storage. I skipped this message as I didn't want to set up everything again from scratch (filling up favorites with all channels in demanded order is hell).
Today my tv started to act strangely - it lost regional symbols in the tv-guide view and lost channel previev in there. I started to crawl through settings to find the regional language options and guest what I've found? "Transfer channel list from/to USB" option in expert settings of antenna menu!!! It was simply there. I thought "hey, maybe it appeared there with some recent upgrade and I have never noticed?... great!". Anyway I didn't find any regional misconfigurations so I put this lost symbols problem to the fact that the memory is full and maybe it couldn't load something...
OK, so I resetted the tv to the factory settings, searched again for all channels and the problems with regional symbols went away all right, so I set up all picture/sound settings again and then thought "great, now let's try this channel list transfer!"... and guess again what? This option magically disappeared from menu, like it wasn't there previously... I mean WTF?!?!?!?!?!?
Also some other settings in menu look different then recently, like "clock" option is greyed out and I can't enter there to set up clock (fortunately the time is all right, but what if it wasn't?).
My theory on that magic is the following:
I think this Series 7 tv has the same common features in the menu like all other Sams TVs, just some options are hidden by the company... At the incident of full cache memory maybe the tv got lost some settings and those restrictions so I could see the hidden options. When I cleared the tv cache it got restricted again and we're back from scratch.
Geez this tv is really giving me a headache and I will never buy Samsung again.
