Quick Panel Background Cropper

On One UI 8.5, making a seamless background across your Quick Panel Controls can be a pain.

If you do it manually in Good Lock QuickStar, you have to position each panel image by eye, one by one, with no real alignment guide. That takes time, feels inconsistent, and makes it hard to get all 4 panels to look like one continuous image.

Quick Panel Background Cropper is here to make that easier.
This app helps you turn one image into matching background PNGs for your Quick Panel Controls, so the image feels smoothly connected across the layout.

What you can do:
• Import a fully expanded Quick Panel screenshot
• Calibrate your Controls layout
• Pick one image from your album
• Preview how it lines up across the panels
• Export PNGs ready to use in Good Lock QuickStar

Supported Controls panels:
• Button box
• Media player
• Brightness
• Volume

Two ways to set it up:
• Default mode for standard layouts
• Advanced mode for rearranged or resized layouts, with extra panel-by-panel adjustment

Important:
This app is only for Samsung Galaxy devices running Android 16 and One UI 8.5.

Intended for:
• Galaxy S series and A series phones

Tip:
Use the built-in calibration help for the most accurate result.
