jqzoom on mobile device

[kassimi.hn]

Hi ! 
 
I'm having an issue with using jqzoom on product pages, well it works good on desktop where I can zoom my product images without any problem , but when I try to do the same thing on mobile it doesn't work : 
 
I did some research on the net where I found that I have to delete this two lines in global.js , which I did but same result : 
 
var viewport = document.querySelector('meta[name=viewport]');
viewport.setAttribute('content', 'initial-scale=1.0,maximum-scale=1.0,user-scalable=0,width=device-width,height=device-height');

 

 

Can you please Help me to fix this or just to disable jqzoom on mobile device if there is no solution for my issue 

 

I'm using prestashop 1.6
