Disable WP Background Image on Mobile Devices

If you have a WordPress blog and many of your visitors view your site using a mobile device, you may want to disable your WordPress Theme’s Background Image. Most mobile users usually don’t have excellent connectivity and are connected through slow networks. Add that to the fact that most mobile internet plans are billed by the amount of data consumed. Your mobile visitors would thank you for it. Another good reason is that with smaller screens, the background image is rarely displayed properly or just covered up by the content.

To disable the Background Image functionality on Mobile Devices, add the code below on your child theme’s functions.php

add_action( 'after_setup_theme', 'ra_remove_mobile_bg_image', 11 );

function ra_remove_mobile_bg_image() {
   if ( wp_is_mobile() && !is_admin() && !is_customize_preview() ) {
      remove_theme_support( 'custom-background' );
   }
}

The code only affects the front-end of the website. If an admin is managing the site using a mobile device then the Background Image functionality would still be available to him or her.
