Hi @jazibzaman
The the_field() function needs the post ID for the second parameter if you call it outside of The Loop. So, it should be something like this:
<span class="aps-1co"> <?php the_field('device_type', $post_ID); ?> </span>
Also, you only need the PHP closing tag after a PHP code. So, in your case, I believe you don’t need it.
I hope this helps 🙂
