Android behaviour with input widget

Community Usage questions

Sorry to ask this here... but, i don't know how to solve this...

When i use an input widget, Chrome on Android won't stay in full screen mode... kind of a popup appears at the top of the screen (with app name, loaded file name, port... and a small warning "http" unsecure...). The only option it gives then to go back to full screen is to reload the whole session...

Any idea ?

btw : android 4.4.4, Chrome 81. No update possible.

Thank you

Adding the page to the device's home screen and launching it from there may solve this.

Thank you. Problem is i've already added it to android's home page... it opens full screen, 'till i try to use the input widget.

I wonder if the main reason to this is the "unsecure http connection"... or stg else...
