Want to remove white bar on top of mobile view screen

Hello,

I want to remove the white bar above my header on mobile phone view.

It’s the bar on the iPhone where you see the time and wifi etc.

There are some other pages who don’t have the white bar but I can’t fix it on home screen.

I hope someone has a solution for this.
