Try:
-webkit-tap-highlight-color: rgba(255, 255, 255, 0); -webkit-tap-highlight-color: transparent; // i.e. Nexus5/Chrome and Kindle Fire HD 7''

* { -webkit-tap-highlight-color: rgba(255, 255, 255, 0) !important; -webkit-focus-ring-color: rgba(255, 255, 255, 0) !important; outline: none !important;}
* { -webkit-tap-highlight-color: rgba(0, 0, 0, 0); }
