Project description:
"Hello,

I’m looking for an experienced Android system developer to implement a system-level solution where Android exposes only one external USB (UVC) camera as two logical system cameras:

Rear camera (BACK)

Front camera (FRONT)

Even though both logical cameras resolve to the same external source, apps must be able to request and switch between Front and Back normally, as they would on a regular phone.

The goal is that all apps, including restrictive ones, detect the external camera as a real system camera, while internal cameras are not visible to applications.

Device / OS

Current device: Pixel 8a

Android 15 or 16 (developer can choose)

Downgrading to Android 15 is acceptable if technically preferable

Requirements

External USB camera is exposed as TWO logical cameras:

One Front

One Back

When an app requests Front or Back, the correct logical camera opens (even if both map to the same UVC source)

Internal cameras are hidden from apps

Solution must be system-wide, not app-specific

Play Integrity must remain passable (currently achieved via Magisk/modules)

Allowed approaches

Android framework (CameraService / frameworks-base)

HAL / vendor / device configuration

Custom ROM (AOSP / Pixel-based / Lineage / crDroid)

Hybrid solutions are welcome

No exploits
No kernel hacking
No solutions that permanently break integrity or verified boot

To apply, please explain briefly

Which layer you would work on (framework, HAL, ROM, or hybrid)

How you would expose the external camera as Front and Back logical cameras

How you would prevent apps from detecting internal cameras

Any technical risks or limitations you foresee

(No code required at this stage — reasoning only)

Payment

Single milestone

Payment upon successful completion (result achieved)

Budget: USD 800 – 1000

Up to +20% increase only if clearly justified by technical complexity" (client-provided description)
