MaheshSharan/FrameX-Android ? reverse-engineered prompt

Build me an Android app called FrameX that lets me see a small draggable overlay on top of games and other apps with live performance info like FPS, CPU speed, CPU cluster activity, RAM, battery temperature, network speed, and ping.

I want it to feel like a clean gaming companion app with an onboarding flow, a dashboard, overlay settings, appearance options, thermal diagnostics, and a performance mode screen. The performance mode should help boost gaming by closing background apps, turning on Do Not Disturb, and applying per game display and volume settings. It should work without root by using Shizuku, and also support rooted devices through Sui.

Please make it work on Android 8 and up, and follow the privacy focused approach, with no analytics, no accounts, and everything staying on device. If you need to check the latest Android or Shizuku docs while building it, go ahead and look them up online.
