Today I have brought an amazing comparison that will leave a lasting impression on the hearts and minds of Android fans: One UI 7 vs HyperOS 2. We are going to talk about animations and smoothness, which are running on Samsung Galaxy S25 Ultra and Xiaomi 15 Ultra.

If you too are an Android lover, then you must know how different a smooth animation experience makes the phone. So One UI 7 vs HyperOS 2 which will win this battle? Read it completely, because this post will keep you hooked till the end!

One UI 7 vs HyperOS 2:

Tell me honestly, when you unlock the phone, swipe between apps, or open quick settings, then that Narmakkhan-like feeling wins your heart. Animations aren’t just for show; they show how responsive and polished your phone is.

There’s a lot of discussion online about HyperOS 2 (which is based on Android 15) and One UI 7, so I thought why not pit the two against each other. In this comparison, both phones—Xiaomi 15 Ultra and Galaxy S25 Ultra—run at 120Hz refresh rate and default animation speed, so everything is fair.

HyperOS 2: Smoothness that steals your heart

First let’s talk about HyperOS 2, which is running on Xiaomi 15 Ultra. Online, like on X (Twitter), people can’t stop praising its smoothness, and I can understand why. As soon as you unlock the phone with your fingerprint, everything happens very fast. Opening and closing apps, browsing through folders, or opening the quick settings panel everything is as smooth as magic.

HyperOS 2 leaves no stone unturned in multitasking as well; switching between apps and widgets is absolutely seamless. If you need speed and fluidity, HyperOS 2 won’t disappoint. Yes, I found the design a little lacking it feels a bit too crowded, but we’ll talk about it later.

One UI 7: Samsung’s new era

Now let’s talk about One UI 7, which is on the Galaxy S25 Ultra. Samsung has taken its software game to the next level, and One UI 7 is proof of that. If you’re upgrading from One UI 6, the difference is clear. Animations are now much smoother and polished, and a big thing there are now parallel animations. This means multiple elements on the screen transition together, which creates a connected and lively feel.

Whether it’s navigating the home screen, opening apps, or entering settings, One UI 7 makes everything look fast and fine. Samsung has paid attention to every little detail, and the animations are in perfect sync with your gestures.

Face to face: Which is better?

So, which one is ahead? If it’s just about animations and smoothness, HyperOS 2 takes the lead. Its transitions are a little faster, especially when you’re scrolling through menus or multitasking. It’s that feeling that makes you say, “this phone is of a different level!” But to be honest, the difference is so small that you’ll only notice it when you use both phones together.

Well, One UI 7 is no less. Not only are its animations smooth, but they also go well visually. Samsung’s design approach is much cleaner and modern, which is quite different from the slightly busy vibe of HyperOS 2.

My Verdict: Smoothness or Style?

If I had to choose a winner based on animations alone, HyperOS 2 would win by a little bit, as it is at the top in raw smoothness. For power users who want speed and flow, it is perfect.

But if I talk about the overall experience design, aesthetics, and polish then I would choose One UI 7. Samsung’s skin is a complete package, which gives a premium look along with smoothness.
