Hi Irigoyen,
With latest 4.12 you will need to first install LunarG Vulkan SDK on your PC. Build the editor. Run the editor and create your project. In the Android Project Settings, enable Supports Vulkan and package for ASTC or do a launch-on to your S7. Check the logcat to make sure it didn’t fall back to ES2 and used the Vulkan driver. You should see:
Compiled with Vulkan support
Vulkan library detected, checking for available driver
Vulkan driver available, will use VulkanRHI
You may also need to set the min/target SDK to 21; I don’t remember if this is necessary, but we do so in our tests.
