I have the KN55S9CAFXZA as well and have been inquiring about the evo kit as well. No one really knows - however Samsung says yes and gave me the number to J&J Parts who specialize in Samsung parts. They have it and says it is compatible. There is a newer unit the 3500 that is coming out within the next month.
I ran into all this when I noticed in my Apps Hub the Amazon Instant Video app no longer worked and an error screen came up stating the device (TV) needs an update. Samsung hasn’t made a single firmware update for this TV. They are treating it like a bastard child. I've had nothing but misery with Samsung about this TV.
Here's the gory details...
I called up for a simple thing - my Amazon Instant Video app in the hub stopped working with an error screen part of which stated in order for it to work "the device needed to be updated". The first tech remoted in and reinstalled the Smart Hub; didn't work. Then he wanted to wipe my TV. I told him no because I had had it calibrated. He said he could upload the settings and reinstall them. She wiped the TV but when it came back up it was in Arabic. I told him to put it back to English. The app still didn't work. He said he was putting me on hold but hung-up - losing my settings. The next tech said it was my DNS. I told her that was just plain stupid since all the other apps are still working. I was on and off hold for the next hour while she fumbled around my TV remotely. I went to the bathroom, came back and she said there was nothing she could do. I went to my PC to do some research on this when my virus scan wen berserk. My Internet Explore was flashing and PC was stalling - it was completely infected. I checked the TV and found that she changed the DNS pointed out to Google (8.8.8.8) which in turn open up my home Network and compromised it. (I've had security issues and had to set-up a sub-network for protection due to my work). I had to completely wipe my PC and reinstall everything.
The next week was one of dealing with several tech at each of the 3 tiers. The least helpful were the people at the "Executive" level - they didn't even know what an evolution kit was!
Two of the tech from the intermediate level were the best. One told me that there was a change to the App Hub and a running update would fix the problem, however - not for my TV. In fact there wouldn't be any update to my TV because it considered canceled. The only way to update it was to get the 2500 evolution kit.
I spoke to another tech at the same level and he agreed but informed to wait for the 3500. He gave me the phone number to contact J&J Parts.
My friends TV purchased in December 2014 got an update and now the Amazon app is working.
I have gone through two TVs of this model - the first one had a bad panel and was exchanged about 8 months into having it. This TV is now out of warranty. I received an extension notice from Samsung but I wasn't going to pay $800 for one year! I've notice a shudder at times where it appears almost like a frame is missing no matter what setting I use.
I've contacted the store where I made the purchase and they seem to be "yes" men for Samsung not really listening and only repeating the support number for Samsung.
After reading online, hearing from Samsung, and being here at the forum I seems to be that the 2500 and the 3500 are compatible for the KN55S9CAFXZA, yet the store I made my purchase at is stating it will not. Since there have no firmware update for my TV I'm not concerned that there may be a problem.
$10,000 for this TV and the company has abandon it!
Okay, now for the interesting part.
I know person who works for a major IT company who has connection with Intel. I was told that Intel originally developed an OLED TV that was curved - I was shown a picture of the proto-type. It was interesting and looked very much like what is the KN55S9CAFXZA, except the screen was actually thinner and was not in a frame but had a more industrial look because it was actually flat but via the remote would bend to the curved position for presentation upon viewing - VERY COOL!
The speaker array was like the SAMSUNG and reason for this "floating design" was to aim the speakers in the frame slightly inward toward the screen - and when in the curved position would act in a mega-phone-like way to aid in amplify the sound.
I was on the list to evaluate the product but the delivery was never made. Intel looked into this and found it was delivered but not to my address but to another - in the next state. Others that were delivered the product sold it and then absconded to their country of origin - they were here under work visas via the large IT company my friend works for.
A year later Samsung announced their TV under limited supply and only slightly changed.
Now for the really interesting part.
The proto-type was going to be released as 1080p however it was actually capable of UHD. The only thing holding it back was the connect "box" - yes, a one connect.
Now, if the KN55S9CAFXZA is compatible with the 2500 and 3500 as stated by Samsung...
OLED is very different from LED and we only know what we've been officially told. As far as I know - no one has broken down the KN55S9CAFXZA and what's inside to actually know what's there.
All I know is Samsung is being extremely unsupportive and co-operative with this subject, this TV and are now treating it as if it doesn't exist.
I intend to purchase the 3500 when it becomes available. I have an extended contract with the store I made my purchase from. If this screws up my TV at least I have Samsung's own word it should have worked.
I had asked them for all the trouble if they would swap out this TV for their top of the line UHD LED - which is still $5,000 less than what I paid - they said no. ... but they did offer me a $25 gift certificate. ... Which I turned down.
I'm spoke to a rep in the "Elite Service" department who has confirmed there was never an update, nor are that going to do one.
The set was one of the first designed with a One Connect, as part of the Smart Evolution Line. As stated on their site - “Evolutionary TV - Smart Evolution allows you to update your Smart TV in the future. With new software and technology that will improve your TV performance – faster speed, more content, more features.”
I was told by their phone support to contact J&J Parts aka
www.samsungparts.com a Samsung Authorized Distributor of Samsung Parts – to order the SEK2500U One Connect; even though it’s not listed on the Samsung site as an option. Yet I found a press release on the web that was posted over 8 months prior to the U.S. release that it was going to be released in Korea, then the UK and Germany for the KN559CAFXA. I found the same item on Amazon, cheaper so I ordered it. It would not work. The TV didn’t even see that it was connected. It seems the back-up option in the menu that must be done first for the new One Connect is not in my TV’s menu – meaning Samsung never intended this TV to be “Evolutionary” in North America. ….which is why there was never any kind of updates!
I am not the only one complaining as told by a support person at Samsung. I have since spoken to the Exec level of support and demanded that they swap out the TV for their top of the line one that IS being supported (due to the differences in technology from my OLED to LED I’ll still stand to lose almost $5000)
Why is Samsung treating this TV like a bastard child and abusing its customers?!
If anyone else has this TV contact me.
