<blockquote><p>
Mobile and Desktop detection works based on the wp_is_mobile() function of the WordPress that detect device based on the user agent data send in the request
</p></blockquote>
<p>Apart from this it also offer ability to remove Css and JS file from specific pages based in the selected page tag conditions</p>
<p>Eg: if css path is https://s.w.org/style/wp4.css</p>
<p>then you can match it with wp4.css or style/wp4.css or s.w.org/style/wp4.css</p>
<p>you use 2nd method (style/wp4.css) for more precise selection (this avoid error when there are 2 style with same file name)</p>


Page Speed Optimizer: HTTP/2 Push, Async JavaScript, and Defer CSS

My websites are entirely in AMP, but this plugin injects non-AMP scripts on evey page. It doesn't even try to inject scripts only in non-AMP. So, kinda useless for me. I hope to give it another try in the future.

Not compatible with AMP

It is one of my mandatory plugins, I always use it. :)

Simple, handy and must-have :)
