When Samsung started talking up its long-term TV software plans, the big promise was that Samsung TVs released from 2023 onward would get free One UI Tizen upgrades for up to seven years. That sounded ambitious at the time, but it is now starting to matter in a real way, as older Samsung TVs begin picking up One UI Tizen 9 and, more importantly for Android users, native Google Cast support. As we noted when covering Samsung’s 100-inch TV launch in Kenya, Samsung has been leaning hard on that long update promise as a selling point for its newer TV lineup.
This rollout, however, has not been clean. Late last year, Samsung began pushing One UI Tizen 9 to some older TVs, but users quickly ran into issues, the most widely documented being YouTube refusing to load properly after the update. Affected users saw the app fail on certain ISP and router setups tied to IPv6.
At the time, Samsung said it was investigating the issue and provided a workaround – a switch back to IPv4. That helps explain why the update seemed to slow down or quietly disappear in some regions. In other words, classic firmware rollout chaos, now on your living room wall.
Now the rollout appears to be moving again. Samsung has already confirmed Google Cast on its 2026 TVs, and the same feature is also confirmed for Samsung’s 2024 and 2025 models running the latest firmware. That means the current Cast-enabled pool, based on the most credible reporting so far, includes all 2026 Samsung TVs, 2025 Samsung TVs once they jump to the newer firmware branch, and 2024 models that have started receiving v2115. Specific sightings already include models like the S90D and S95D.
The 2023 situation is a little murkier. Samsung still has not published a neat public list of every older TV getting Google Cast, but at least some 2023 models are now receiving the One UI Tizen 9 upgrade. SamMobile, for instance, spotted the S90C picking up Tizen OS 9 via firmware version 6500 in India. So from my reading of this rollout, 2023 support is clearly happening, but Google Cast on every eligible 2023 model is not yet fully documented in public.
That is why firmware version 2115.3 matters. On the 2024 family, the changelog points to improved behavior for YouTube, Apple AirPlay, the Music app, and websites, plus “quality stabilization.” That sounds exactly like the kind of cleanup update you would expect after the earlier rollout problems.
And for Android users, it lands at an interesting time. Just days after we reported about Philips ditching Google TV for Titan OS, Samsung is going the other way and embracing Google Cast more deeply. It also comes after wider questions around the future of casting itself, which we explored in why Netflix killed Chromecast support. For Samsung TV owners in Kenya and elsewhere, the message is simple: if you own a 2024 or 2025 model, Google Cast is now effectively on the way, while 2023 owners should start watching the update menu a lot more closely.
