In the mobile version, when the product card is opened, scrolling does not work if the finger touches the photo area of the product.
For example, open the link on your mobile device.
If you try to scroll the page, it can be done only above or below the picture. If you drag your finger around the picture, the page does not scroll.

Dear alphacoil

Maybe the main image use zoom function prntscr.com/hphl79 , so you can't focus at the image to move on the page. if you want you can to show the main image to smaller prntscr.com/hphnb3

by add the css at the end of this file: /templates/sj_topdeal/css/presets/preset4.css
@media (max-width: 767px){
.productfull .product-image .image_middle {
width: 70%;
}
}

thanks
