New compatibility issue

After some tests, I noticed that this plugin is not compatible with build in android web browsers. Tested it on an android tablet and on an android phone and both have the same symtoms. The website is not displaying properly or the slider is acting funny. With firefox and chrome everything is ok. Any ideas? Thank you.
