@TheBricktop Hi, based on user reports of S8 with Android 9 on vulkan.gpuinfo.org, it looks like the S8 GPU drivers do not support all the required Vulkan extensions for ALXR & Monado, the most important one being VK_ANDROID_external_memory_android_hardware_buffer

well there goes my hopes
so whats the minimal api level ? S8 has around 1.1.66

The min API level for ALXR is currently 28 but it could be possible to bring it down to level 26 with some small changes i believe.
