Druhá časť - otáčanie:

uses
  ..., FMX.Platform;

procedure TLogin.FormCreate(Sender: TObject);
var
  ScreenService: IFMXScreenService;
  OrientSet: TScreenOrientations;
begin
  if TPlatformServices.Current.SupportsPlatformService(IFMXScreenService, IInterface(ScreenService)) then
  begin
    OrientSet := [TScreenOrientation.soLandscape];
    ScreenService.SetScreenOrientation(OrientSet);
  end;
end;
