Android Engineer for OnePlus 7 Camera Remapping

I need an Android systems engineer to rebuild the vendor image for the OnePlus 7 (codename guacamoleb) running crDroid 15 so the phone treats a UVC-compatible external camera as the only available camera. Scope • Tweak the camera HAL configuration only—no kernel or ServiceManager rewrites are expected unless a tiny patch is unavoidable. • Expose exactly two logical camera IDs that map to the external device: 0 = rear, 1 = front. • Suppress or mask every on-board sensor so dumpsys media.camera, Camera2 API, and CameraX report only the UVC unit. • Ensure the external camera works for video recording and real-time streaming in any app; still-photo support is optional. • Make the external feed the default for all apps without extra user steps. Deliverable A flash-ready vendor.img or ZIP that I can sideload. After flashing and rebooting, I will verify: 1. adb shell dumpsys media.camera lists only IDs 0 and 1, both pointing to the UVC device. 2. Stock Camera, Zoom, and other third-party apps open the external camera automatically for video and streaming. 3. No internal camera shows up anywhere in UI or logs. Please include a concise change log and, if possible, the overlay or patch files you edited so I can repeat the build later.
