Hello,
If you selected Products per row 4 in Theme Options->Product Page layout you can use following code in custom.css file.
@media (max-width: 479px){
.products-grid.product-count-4 .product:nth-child(n) {
width: 50%;
}}
if per row 3 then please add this code
@media (max-width: 479px){
.products-grid.product-count-3 .product:nth-child(n) {
width: 50%;
}}
Regards,
Robert Hall.
