For phone customization lovers, Samsung’s Good Lock suite is probably already a fan-favorite tool. It has always been the ultimate playground for tailoring the Galaxy experience, but an upcoming software refresh is about to push those boundaries even further. A new leak of Samsung’s Android 17-based software, One UI 9, shows that the tech giant is cooking up a massive overhaul for its popular “Home Up.”
A post shared by insider GalaxyTechie on X gives us a clear look at an early build of the software. The update introduces two major quality-of-life upgrades that power users are going to love: highly customizable backgrounds for the bottom app dock and an advanced multi-finger gesture system.
Redesigning the app dock from scratch
The bottom dock—often called the “Favorites” tray—has traditionally been a rigid part of the user interface. Samsung wants to change that. With the One UI 9 update, you can break away from stock configurations and completely redesign this area to match your custom wallpapers or icon packs.
The software introduces an absolute laundry list of visual adjustments. Instead of a basic transparent strip, you can toggle a dedicated custom background and apply advanced effects like depth blur, drop shadows, or distinct solid colors. The interface also lets you fine-tune the corner radius, adjust vertical and horizontal padding, and even set a completely custom background image.
To make things easier, Samsung is building in pre-set design themes with names like Mint Flow, Metal, and Pastel Brush. Additionally, you will be able to alter the total number of apps allowed in the tray, keeping it entirely independent from your main home screen grid size.
Five-finger gestures for absolute control
The second headline feature focuses entirely on navigation efficiency. Samsung is introducing a multi-finger gesture control layout that might be the most comprehensive system we have seen on a stock launcher.
The interface will support simultaneous inputs using two, three, four, or even five fingers at once. You can map different actions to classic directional movements like swiping up, down, left, or right, alongside single taps, double taps, pinches, and long presses. Instead of digging through settings menus, a quick multi-finger pinch or swipe can immediately take a screenshot, pull up a search window, adjust system volume, change display brightness, or launch your favorite application shortcuts (via SammyFans).
The Android Headlines Take
Customization capabilities are one of the key selling points of Samsung phones. One UI constantly competes to offer the most UI tweak options, whether by default or through Good Lock’s modules. This is a radically different approach from Google Pixels, which locks down its software launchers and restricts user agency in the name of simplicity—although they have become more open to customization lately.
According to rumors, One UI 9 won’t be a revolution full of new features but rather a refinement. So, expanding customization options with more granular visual and system tweaks helps give users exactly what they want. Samsung’s approach of offering these options through Good Lock modules is also neat, as it allows for a relatively lightweight base software to which you can integrate more customization options if you like.
