Hi andreyogld3d,

It seems the phone you’re using has a PVR GE8322 GPU (HTC Wildfire E - Full phone specifications), which was designed to support Vulkan (Find out about the PowerVR GE8322 embedded GPU IP Core).

However, it might happen that the SoC manufacturer has not added Vulkan support to the drivers they distribute for your device. Since they are the ones making those decissions, I recommend you contact them so they can inform you about future updates that would allow Vulkan API support on your device.

Best regards,
Alejandro
