Hello, I've tried to create a mobile email template on mobile, all seems to be okay, but when I test this email on Samsung Galaxy S3 (real-time) I just dosent split colums.

CSS I use:

@media screen and (max-device-width: 600px),
        screen and (max-width: 600px),
        only screen and (-webkit-min-device-pixel-ratio: 1.5),
        only screen and (min-device-pixel-ratio: 1.5),
        only screen and (min-resolution: 120dpi) {
        .mobilesplit {width:100%!important; float:left!important;  -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; border-top: none !important; border-bottom: none !important;}

It works fine in iOS and Litmus tests (android and iOS) but dosent on Samsung, anyone knows solution to my problem?
