When you run this, the system first tries to read the current property before writing it. The setprop command fails with "access denied finding property" because your shell lacks the rights to query that vendor property.

If you still see the error, check these: Access Denied Finding Property Vendor.camera.aux.packagelist
In the intricate world of Android development and device customization, few things are as frustrating as an opaque error message. For developers working with Camera2 APIs, device maintainers building custom ROMs, or power users utilizing tools like Magisk to unlock hidden features, the error string is a familiar hurdle.
), explicitly enabling hardware acceleration in the manifest can resolve this specific vendor access error: application android:hardwareAccelerated Use code with caution. Copied to clipboard 4. Background Service Type (Android 10+) When you run this, the system first tries
Apps like Open Camera, GCam (Google Camera ports), or specialized photography apps often attempt to access all available camera lenses. When the app queries the camera service, the HAL (Hardware Abstraction Layer) checks the vendor.camera.aux.packagelist . If the app is not listed, and the system enforces a strict SELinux policy, the access is denied, and the app defaults to the main lens or crashes.
There are three primary scenarios where this error manifests: For developers working with Camera2 APIs, device maintainers
A: Partially. Samsung uses additional libexynoscamera libraries that enforce their own whitelist. You may need a Samsung-specific GCam mod (e.g., ZGcam).
For developers, this is a nightmare. The Android Camera2 API promises a unified interface, yet vendor-specific HAL layers break this promise. The error log indicates that the system is actively filtering access, turning a hardware feature into a gated community.
