I enabled this hidden Samsung setting and my Galaxy feels like a new phone

My Galaxy S25 Ultra has never felt slow, but after using it every day for months, the interface had started to feel a little too familiar. App launches, swipe-up gestures, and transitions all worked fine, yet I couldn’t shake the feeling that One UI could feel quicker and more responsive. I didn’t want to disable animations entirely or mess around with aggressive Developer Options tweaks just to save a few seconds. As it turns out, Samsung already gives me excellent control over all of this, but it hides those controls inside Good Lock’s Home Up module. My Galaxy wasn’t slow, but it felt familiar The speed wasn’t up to the Pixel and iPhone level My Galaxy S25 Ultra was never actually slow. Apps opened quickly, multitasking was smooth, and I rarely ran into any real performance issues. But after comparing it with my iPhone 17 running iOS 27 and Pixel 8 running Android 17-based Pixel UI, One UI started to feel a little different in comparison. The app-opening and home animations on my Galaxy felt slower and slightly rubbery, especially when I quickly swiped between apps or returned to the home screen. The phone had plenty of power, but the animations made it feel less immediate than the other two. I could have opened Device Care, cleared memory, or used one of Samsung’s temporary performance-boosting options, but that wasn’t what I wanted. RAM wasn’t the problem, and I didn’t want a short-lived fix that I would have to repeat afterward. I wanted something that permanently changed how One UI responded to my gestures. That’s when I started digging through Good Lock and found a neat option to boost my Galaxy S25 Ultra’s behavior. Samsung hides much deeper animation controls I changed how gestures respond Samsung already gives me far more control over animations than I expected, but most of it is buried inside Good Lock. I opened Good Lock, downloaded the Home Up module, and headed to Gesture settings. From there, I enabled Home gesture animation tuning, which immediately opened up a few different animation styles. The biggest change for me was switching from Classic to Dynamic. Dynamic makes the home gesture feel quicker and more responsive, without removing the animation entirely. It still looks polished, but there is less of that slow, rubbery movement I noticed before. There is also a Simple tuning option with a slider, so I can fine-tune the animation instead of choosing a preset and calling it a day. I also enabled App open animation tuning and moved the speed meter to Fast. That made an equally noticeable difference when launching apps. There is an Advanced tuning section too, with plenty of additional controls if I want to obsess over every detail, but I honestly didn’t need to go that far. These two changes were enough for me. My Galaxy S25 Ultra now feels quicker. Apps seem to fly open, and swiping back to the home screen feels far more immediate. The hardware hasn’t changed, but the way One UI moves finally matches the speed I expect from a flagship phone. It works better than the Developer Options trick It makes One UI feel personalized I have used the old Developer Options trick before, where I reduced the Window animation scale, Transition animation scale, and Animator duration scale to 0.5x. It makes Android feel faster, but it is also a pretty blunt solution. Everything simply speeds up, whether the animation actually looks better or not. Good Lock feels much more refined. With Home Up, I am not just cutting animation time in half. I can change the animation style, adjust how quickly it reacts, and tune app-opening behavior. That gives me a much better balance between speed and polish. I still get smooth transitions, but they no longer feel overly stretched out. This tweak also reminded me why Good Lock is one of my favorite parts of using a Samsung phone. I can change how gestures behave, how apps open, how the home screen works and looks, and even tweak the Samsung Keyboard. That is why I would encourage Galaxy users to get a little creative with it instead of copying my exact settings. Home Up alone gives you plenty to experiment with, and the rest of Good Lock opens up even more possibilities. The easiest Galaxy upgrade costs nothing I didn’t expect an animation tweak to make such a noticeable difference, especially on a phone that was already fast to begin with. But that’s exactly why this setting surprised me. This tweak changes the part of the experience I interact with constantly. After changing the animation behavior to my liking, the phone feels responsive and polished. That’s the kind of customization I appreciate most about Samsung. Good Lock doesn’t just let me change how my Galaxy looks; it lets me change how it feels to use every day.
