any help ?

If your need is to alter the status bar, didn’t it occur to you to look for a suitable extension?
They lack ideas and will, all they do is ask.


Thank you my friend
i used this extention before it gives me a transparant status bar background But these icons still appear. ( screen 1)
also in landascape orientation that top of screen it still black. ( screen 2)
