New screen / glass, touch not working 100%.

Good Day All,

I had ordered a new front glass replacement which came with the LCD and digitizer etc, I got this on my phone without any issues, the screen works 100%, however, the touch screen doesn't appear to be functioning 100%.

I opened the notes app and tried typing each letter of the alphabet, I had difficulty tapping on "H" and "N" and could not hit at all "J" and "U". If you look at the keyboard these keys are all in the same vicinity from top to bottom on the screen. I am wondering if I maybe didn't put down the cable all the way on the motherboard? Or if I got a bad screen?

Thanks!
