'stat unit' does not show gpu time on android

why the gpu time does not show up? my device is snapdragon 820 , system is andriod 6.0

same as well. I believe ES2 is not using GPU. Since i tested on iOS by disable Metal, no GPU show as well. Once enable Metal Forward Rendering, the GPU shows up.

I have the same problem

same problem with me. And I don’t know why
