How to change text in tooltip for social media icons in header.

I’ll do my best to help, although I am not the person who changed it.

If you are using child themes, then you’ll have to change it in the child.
We changed a line in /wp-content/themes/enfold/includes/helper-social-media.php
You’ll see the if statements below, I wanted to change ‘mail’ to ‘Check your Email’ and ‘support’ to ‘Customer Support’

Hope this helps. Good luck.

Here is the code inside the helper-social-media.php for me beginning at line 55. I’ll give you a big chunk so you can see the context.

		function build_icon($icon)
		{
			global $avia_config;

			//special cases
			switch($icon['social_icon'])
			{
				case 'rss':  if(empty($icon['social_icon_link'])) $icon['social_icon_link'] = get_bloginfo('rss2_url'); break;
				case 'twitter':
				case 'dribbble':
				case 'vimeo':
				case 'behance':

				if(strpos($icon['social_icon_link'], 'http') === false && !empty($icon['social_icon_link']))
				{
					$icon['social_icon_link'] = "http://".$icon['social_icon'].".com/".$icon['social_icon_link']."/";
				}
				break;
			}

			if(empty($icon['social_icon_link'])) $icon['social_icon_link'] = "#";
			$blank = "target='_blank'";
			
			//dont add target blank to relative urls or urls to the same domain
			if(strpos($icon['social_icon_link'], 'http') === false || strpos($icon['social_icon_link'], home_url()) !== false) $blank = "";
			
			$html  = "";
			$html .= "<".$this->args['inside']." class='".$this->args['class']."_".$icon['social_icon']." av-social-link-".$icon['social_icon']." social_icon_".$this->counter."'>";
			$html .= "<a {$blank} href='".$icon['social_icon_link']."' ".av_icon_string($icon['social_icon']);
			if($icon['social_icon'] == 'mail'){
				$html .= "title = 'Check your Email'";
			} elseif($icon['social_icon'] == 'support'){
				$html .= "title = 'Customer Support'";
			} else {
			 $html .=  "title='".ucfirst($icon['social_icon'])."'";
			}
			 $html .= "><span class='avia_hidden_link_text'>".ucfirst($icon['social_icon'])."</span></a>";
			$html .= "</".$this->args['inside'].">";

			return $html;
		}
