One UI Home Clone is an independent Android launcher for people who like Samsung's familiar home-screen flow and want an open Kotlin and Compose implementation. It is a clone, not a port. No Samsung code, logos, wallpapers, or proprietary glyphs are included.

Why install it

• The Home and Apps screens follow the interaction model Samsung users already know.
• Finder searches installed apps, launcher settings, actions, shortcuts, and optional local contacts.
• Home pages support folders, app shortcuts, notification badges, widgets, grid controls, and a dedicated edit surface.
• Phone portrait, landscape, foldable-width, and tablet layouts use separate responsive grid contracts.
• Standard and reduced motion modes respond immediately without restarting the activity.
• Local backup, restore, and sanitized diagnostics tools make experimentation recoverable.

This project favors familiar behavior over a wall of novelty settings. The goal is a launcher that feels easy on the first swipe.

Install

1. Download the latest signed APK.
2. Open the file on your Android device and allow installation from that source if Android asks.
3. Launch One UI Home Clone, then tap Open Home settings.
4. Choose One UI Home Clone as the Home app.

Android may place the Home app setting under Settings > Apps > Default apps > Home app. Existing installs can be upgraded without clearing launcher data:

adb install -r one-ui-home-clone-v0.2.5-release.apk

Privacy

One UI Home Clone has no INTERNET permission. Launcher data stays on the device unless you choose to export a backup or diagnostics file.

• Installed-app inventory is used locally to draw icons, folders, search results, and launch targets.
• Contact search is off by default. It needs both the in-app setting and Android's Contacts permission. Names are never added to recent searches or exports.
• Notification badges are also off by default. When enabled, the launcher keeps only aggregate per-app counts.
• Settings, pages, recent Finder searches, hidden apps, and widget IDs live in app-private storage. Android backup is disabled for this data.

The diagnostics export contains version, Android SDK, launcher state, sanitized crash fields, and aggregate counts. It does not include app names, contact names, notification text, or search history.

Build and verify

The Android project lives in prototype-android/. It needs Android Studio with API 37 installed and JDK 17 or newer.

cd prototype-android
$env:JAVA_HOME='C:\Program Files\Android\Android Studio\jbr'
$env:ANDROID_HOME="$env:LOCALAPPDATA\Android\Sdk"
.\gradlew.bat :app:testDebugUnitTest :app:lintDebug :app:assembleDebug

Run the connected Compose checks on an emulator:

$env:ANDROID_SERIAL='emulator-5590'
.\gradlew.bat :app:connectedDebugAndroidTest

Signed packaging uses a local prototype-android/keystore.properties file. Copy keystore.properties.example, add your keystore values, then run:

.\gradlew.bat clean :app:releaseChannelPackage

The release task writes a versioned APK and JSON metadata with its SHA-256 digest under prototype-android/app/build/outputs/release-channel/.
