Why is PaperScan not supported on my Android device?
Your device doesn't provide drivers for Vulkan. Vulkan is a cross-platform API for high-performance 3D graphics. It provides tools for creating high-quality, real-time graphics in apps and offers lower overhead, more direct control over the GPU, and lower CPU usage.
As this API (Vulkan) is not supported on your device, it is not possible to use PaperScan, as PaperScan uses this API to take images.
