Touchscreen won't work in certain spots, even after repalcement

My touchscreen won't work in certain spots, so I can't type certain letters on the keyboard, and I can't use certain buttons when on apps.

If I use the keyboard in landscape mode then I am able to type the letters that I can't in portrait mode, which shows that this is a touchscreen issue in certain spots on my screen.

The weird thing is I just replaced the faulty screen with the screen from my previous iPhone SE phone (same model) and I'm still having this issue ??? Any idea as to what's going on? Maybe I need to replace a different part?

Any insight will greatly help. Thank you for reading.
