How to remove slider from the mobile view Hellfire theme

Hi, I would like to remove the slider only from mobile version.
How does the framework determine whether to display the mobile or normal view?
Thanks in advance for advices!

Solution #1.

css/tablet.css, css/mobile.css

.slider-container { display:block; } ===> .slider-container { display:none; }

but slider steel loading, killing traffic. so

Solution #2.
functions.php
add:

function ifmobile() {
	if (preg_match('/mobi/i', $_SERVER['HTTP_USER_AGENT'])) return TRUE;	
}

top.php
Change:

<?php if ((is_front_page()&&$SMTheme->get( 'slider', 'homepage'))||(!is_front_page()&&$SMTheme->get( 'slider', 'innerpage'))) { ?>
	<div class='slider-container'>
		<?php $SMTheme->block_slider();	?>
	</div>
<?php }	?>

to:

		<?php if (!ifmobile()&&((is_front_page()&&$SMTheme->get( 'slider', 'homepage'))||(!is_front_page()&&$SMTheme->get( 'slider', 'innerpage')))) { ?>
			<div class='slider-container'>
				<?php $SMTheme->block_slider();	?>
			</div>
		<?php }	?>

Slider not loading in mobile & tablet view.
