Inset map can't show map

I run the demo app and choose the Lab/Inset map, insert map can't not show
My test phone is OPPO F1.
I change another test phone(Samsung Note9), insert map can display
I don't know what restrictions about this sample.
Fist picture is Samsung Note9 screen, second picture is OPPO F1 screen.
