Hi,
Is there a way to move or delete, on the main screen, the google search window?
All the other item can be move to another screen, but not this one?
Thanks in advance

You can try many ways:

Hi,
Thank you for this quick reply.
I thought it was a specific problem with Blackview, but with the links you  mentionned, I see that it's an Oreo problem.
So I googled severy web site, and finally, I suppose the best way is to use an alternate launcher.

Regards.

May I suggest Lawnchair app .
It's very light and have a lot of settings. (free without ads)

afaik, you need to use a launcher like Nova Launcher since the google search bar is otherwise embedded in the home page. Can't otherwise be moved .
