RajnishKMehta/DhwaniControl ? reverse-engineered prompt

Build me an Android app that helps people who have broken or unreliable volume buttons quickly open the phone’s normal volume panel.

I want it to feel simple and polished, with a clean modern look, and it should let the user trigger volume control in a few easy ways. Add a Quick Settings tile, an edge swipe gesture from either side of the screen, and a floating button that stays on top and can be moved around. The floating button should be customizable so people can change the icon, color, and transparency, and lock it in place if they want.

It should be lightweight, privacy friendly, and not ask for anything unnecessary. Make sure it works well in the background without draining battery too much. If you need to check current Android guidance or permissions, look up the latest docs online.
