For years, iPhone users boasted about their "smooth animations" and mocked Samsung's UI for its micro-stutters. But the tables have turned. With the release of One UI 7 (based on Android 16), Samsung has executed the biggest redesign in its history. From non-linear animations providing a "floating" feel to AI translating WhatsApp video calls. In this 2000-word deep dive, Tekin Plus puts every change under the microscope to see if Apple's software reign has finally ended.
1. Introduction: The End of "Micro-Stutters" and a New Era 1.1. Goodbye TouchWiz Legacy If you're a long-time Android user, you surely remember Samsung's heavy and slow "TouchWiz" UI. Even with One UI,
Samsung was always a step behind Apple (and even Google Pixel) in terms of "Smoothness." There was always a micro-stutter when exiting the camera or switching apps that ruined the "Premium" feel. But November
2025 marks a turning point. One UI 7 isn't just a new skin with different icons; it's a complete rewrite of the OS graphics code. Samsung finally admitted that "powerful hardware isn't enough" and focused
100% on User Experience (UX). 1.2. Project "Super Smooth" Samsung engineers ran an internal initiative called "Super Smooth." The goal was simple: achieve a locked 120Hz frame rate in all conditions, even
with 20 apps open. The result? In our tests on the Galaxy S25 Ultra , we didn't experience a single frame drop in system animations. This level of optimization was previously only seen on iOS. 2. Feature
#1: Non-Linear Animations 2.1. Motion Physics: Why Icons Have Weight In previous versions, animations were linear and artificial. In One UI 7, Samsung uses advanced Bézier curves. When you swipe up to
close an app, the window's closing speed matches your finger's velocity exactly. Swipe gently, and it closes gently. Throw it hard, and it closes with momentum, even showing a slight "bounce effect" as
if a physical object with real weight hit the ground. These nuances make the interface feel alive, not like a cold glass screen. 2.2. Interruptible Animations iOS's biggest advantage was always "Interruptible
