Hi All!
I have a joystick that is connected to my phone.
When my application is running a can see than joysticks buttons are pressing.
But when the phone screen is locked, I don't see notifications about it in my app.
What can I do to receive joystick button press in my application when the screen is locked?

Receivers code

procedure TForm1.FormKeyDown(Sender: TObject; var Key: Word; var KeyChar: Char; Shift: TShiftState);
begin
  inc(i);
  Memo1.Lines.Add('i=' + IntToStr(i) + '; Key=' + IntToStr(Key));
end;

The result of the application, photos of joysticks and the source code are in the attachment.
