Cross-platform validation issues: links not working on some devices

I have a magento site, and a menu on it. They menu isn't super complicated. Here is a snippet of the menu:

<ul class="nav top-main-navigation">
<li class="dropdown"><a href="/jewelry-categories.html">Jewelry</a>
<ul class="dropdown-menu">
  <div class="jewelry">
<li><a href="/jewelry-categories/pendants.html">Pendants</a></li>
etc ...

However, I've noticed that on samsung devices the links won't redirect to the page they are suppose too. It works on desktop on multiple browsers and Iphones, and other android phones. What can I do to fix this intermittent issue?
