next_post_link in single.php and custom post type

I got 3 types of custom types : videos, galleries and podcasts. They use the default taxonomy categories.

When viewing a single custom post let’s say a video, the next_post_link() (or previous_post_link) function displays a link only to the next or previous post from this custom post type.

How could I get it to display the next post from any post type? tried to search hours on google without finding anything relevant to this. Anyone facing the same issue?
