Gioonee m5 mini touchpad

[Gerald phone repair]

Am a mobile phone engineer
I changed a touchpad of gioonee m5 mini yesterday and discovered that when u touch or click an icon,it will respond as if you hold the icon
I need help on the issues
But,though I suspect it's the screen or board

Could be it's an incorrect part?
