so for those like me who are interested...here are the links to their review..
comparison of touch screen response
p.s for the curious but lazy, the z1c has a touch response of 70ms second only to ipad mini with retina display (54ms) better than iphone 5 and 5s (75ms) and nexus 5 (75 ms)
dunno about you but this info makes me a happy person
Now I don't know if this is with AUO or JDI panel, maybe I'll try contact them later to find out..cheers.
