Building a React 19 Tool to Calibrate Custom Wallpapers for Samsung's OneUI QuickPanel

Following the latest Samsung OneUI update, I wanted a simple way to align and crop custom wallpapers to fit the QuickPanel layout perfectly without guessing pixel coordinates or dimensions.

Existing tools often only let you apply static images without options to edit image properties, adjust blur/opacity, or calibrate to your device's exact panel layout. To solve this, I vibecoded OneUI QuickPanel Customizer in a collaborative pair-programming partnership with an AI coding assistant, built using React 19, Vite, and Tailwind CSS v4.

🚀 Key Features

  • Visual Calibration: Upload a screenshot of your QuickPanel to auto-calibrate active panel regions.
  • Built-in Image Editor: Crop, scale, align, and tweak blur & opacity filters right inside the web app.
  • Real-time Live Preview: View how your customized wallpaper blends with UI elements before downloading.
  • Persistent Profiles: Save calibration profiles for your specific Galaxy model locally in your browser.

🛠️ Stack & Engineering

  • Frontend: React 19 + Vite 8
  • Styling: Tailwind CSS v4
  • Canvas Engine: HTML5 Canvas API for sub-pixel image cropping & filters
  • Workflow: Vibecoded with an AI coding assistant
