I've just found a solution for this matter, there's a zoom module named ElevateZoom, which you can get here on prestashop forum for free.
This zoom is more modern and you are able to disable on mobile phone and tablets by going on modules configurations.
That's the link for the module: https://www.prestashop.com/forums/topic/301879-module-elevatezoom-for-prestashop-zoom-and-magnifier-effects-on-images/?do=findComment&comment=1526266
Worked fine on my store (Prestashop 1.6);
Hope it can be useful for you guys as well.
