One UI Home is Samsung’s built-in Home-screen app on Galaxy phones and tablets. It provides the screen where you launch apps, place widgets, and arrange shortcuts. Seeing it in battery usage is not, by itself, a sign of malware: it is a normal part of using the Home screen, and Samsung says it cannot be removed from Galaxy devices.
What One UI Home does—and what it is not
Samsung describes One UI Home as the preinstalled app that provides navigation tools for launching apps and widgets from a Galaxy device’s Home screen. It manages that screen’s layout and items; it is not the entirety of Samsung’s One UI software experience. Samsung’s overview covers Galaxy phones and tablets, and notes that screens can vary by software version and device. Samsung’s One UI Home overview

In practical terms, if you see One UI Home listed in a device’s battery usage, it reflects activity associated with the Home-screen app. The listing alone does not establish a problem. The Samsung support material describes its normal role, but does not provide a battery percentage or a diagnostic threshold; usage figures depend on the particular device and conditions.

No. Samsung says One UI Home comes preinstalled on Galaxy phones and tablets and cannot be removed. You can choose another compatible home app as the default on devices that offer one, but that changes which app opens as the Home screen; it does not uninstall One UI Home. Samsung’s overview

- Tap Add to Home.
To have future installs appear on the Home screen automatically, Samsung’s documented route is Settings > Home screen, then turn on Add new apps to Home screen.

Move, group, or remove an icon
- Move: Touch and hold an icon, then drag it to the position you want.
- Create a folder: Drag one app icon on top of another.

How to personalize the Home screen
One UI Home lets you place and manage widgets and other Home-screen items. The controls you see depend on your phone or tablet, software version, and region, so do not assume that a setting shown for one Galaxy device is available on every other one. Samsung’s overview of One UI Home describes Home-screen customization, while its newer version guide details changes specific to One UI 7.

Yes, if another home app is available for your device. Samsung Japan documents this example path: Settings > Apps > Choose default apps > Home app, then select the home app you want.
