OneUI 7 AI features works faster on S24 Ultra and Z flip 6 than on S25 ultra

This video shows how OneUI 7 AI features (except Now Brief) work's faster on S24 ultra and Z flip 6 than on S25 ultra and that is possible reason why Samsung delay to release OneUI 7 on older flagships

I was a beta tester and thought it was well polished as well. But I'm not privy to all the reports and feedback as Samsung are. So why then do you think "some" users account for the whole process?

I can say the S24 Ultra was a complete mess comparatively to the S25 Ultra on launch and that was the updated OneUI not in beta release. Can't say I care for half working, literal game crashing released software from day 1. No such issues on the S25 Ultra though.

I mean, I'm saying they should include it on both. We don't know if one phone decided to use local where another decided to use cloud. Having local processing only disabled doesn't use the cloud for everything, some things are still local. Though we don't know which things. I'm suggesting making both phones only run locally would remove any error from one phone using cloud and the other using local resources. Plus if both phones only used the cloud, they should be equal.

Plus with some research, the s24 and s25 seem to use the same storage technology. Although, higher capacity phones in some regions get higher speed ssds. So for all we know, that specific s25 might be using a slower older storage system compared to that specific s24. Eg, that s25 is 256gb and the s24 is 1tb, the s24 would have faster storage

Then why are you obsessed with the OneUI 7 release exactly or think that it's "purposefully" being delayed has anything to do with witholding customers to anything, especially in regard to AI?

[Sonora]

Hah, Android 15 (not just Oneui7) is ALL about AI features and you ask me why I'm obsessed with it? I like  AI 🤭😋😂

So, you have an S25 Ultra and try to generate an image or process a video with on-device only mode. How fast is that process? Gemini, perhaps lying, says that generating images is a very demanding process and requires at least 16 GB of RAM.

[arianwen27]

It depends a lot on the AI models being used. Samsung hasn't said which models they use for Samsung AI. So Gemini image creation might take 16 GB of RAM but is server-only. But Samsung might not use Gemini for local image generation. Take the grammar check, for example. Using the cloud, it gives way better results than when run locally. The local model is a lot smaller and less powerful than the one the cloud AI servers use.

Also to clarify full image generation cannot be done locally on the S25U. Trying to generate images with local only enabled gives an error. Generative expand can be ran locally though.

As another example, the deepseek ai models can range from a few gigabytes to somewhere around 400gb. Both are the same model, just the smaller one is easier to run and not as smart. Same with local phone ai. The server version is bigger and smarter. The local version isn't as smart so it fits on a phone. Samsung really hasn't said much about local vs cloud and how smart they really are. So we have to guess the technical details. I know for a fact some of the cloud models are bigger and better than local phone models. Because I've tested it. Which ai systems are affected by this? I don't know I haven't tested them all.

My best theory is there's 3 types of samsung ai.

Small and simple, runs locally on the phone itself. Such as galaxy enhance x or now brief.

More advanced ai. These have 2 versions of the ai model. If you have Internet, your phone uses a samsung server to process the ai, that server has a really smart ai that then sends you the result. If you don't have Internet or have local only enabled, your phone uses a local dumber model for the same task. Slower, worse outcome but works.

Finally, very advanced. These are features using ai models too advanced for a phone to handle. There is no local version of this model. This is things like full image generation.

[Joeeye]

But as you already pointed out, right now the S24 Ultra runs practically all AI tasks the same as the S25 Ultra (to which I strongly agree) so my question remains.

The problem I see is Google and Samsung have made huge marketing campaigns based on AI so a lot of users who aren't aware think that most of the current AI is made possible purely by android 15. This simply isn't true, nor is it even where AI in android has been used. It's been about 9 years now where AI features have been slowly creeping in under the hood. Gemini, which relies heavily on Cloud based AI operations, is functionally identical on any device which is capable of running it (that's pretty much all Android 10+ phones/tablets with at least 4GB RAM). Furthermore, as Google plans to roll out Gemini on all it's products and connected devices, this means even devices like the Google Home Mini and Google Nest Hub may eventually run Gemini (these devices only have 2GB RAM).

[Sonora]

But it's not the same. If I want Gemini to tell me something about what it sees on the screen, I have to call it with "Hey Google" to get what you get on Android 15 when you press the Bixby button

Funny is that after I called Gemini, I called Bixby to take screenshot about Gemini 😂 

Gemini is deeply in Android 15, not only on Samsung phones, but on any other android phone (flagship) which running Android 15. One Plus 12 have all AI features that S25 ultra have...One Plus 12 have Snapdragon 8 gen 3....and  16 GB RAM.
