My Navigation keys doesn't hide in fullscreen mode

[Android Central Question]

Hi. I am using Huawei GR5 2017. My concern is when I am streaming on Google, the navigation keys (triangle, circle and square icon) doesn't hide in fullscreen mode. Can you please help me? Thanks a lot.

Welcome to Android Central! What do you mean by "streaming on Google"? Are you streaming a video on a website using Chrome? Certain apps might not code things correctly to make the screen completely immersive (i.e., hiding the nav buttons).
