I just replaced the touchscreen digitizer of my LG - P880 (Optimus 4x HD) as it was broken because of falling down the floor from balcony,I bought a new one from ebay as it was not available at the LG service centers(I digged all the big cities in India including Delhi,Mumbai,and Bangalore) So i decided to purchase it from a 3rd party . I replaced it as it should be, everything was done by a professional, But I don't know why the touch is not behaving as it should.
The touch is working properly in every corner of the screen but when it comes to moving touches , it sort of lags,it jumps between the 1 to 2 mm gaps. It's accuracy is not that good ,I can understand that it can not match the original digitizer but at least should let the touch move around smoothly.

I searched a lot and what i found was that our device uses NVidia's direct touch technology,and maybe the third party manufacturer did not take this thing in account.
Please help me troubleshoot this as I don't know much about hardware.
