If a different "known good screen" does the same (a whole batch can be bad), then the issue can be with a chip on the board that controls touch. It would be partially separated from the board, causing some areas of the screen to become unresponsive.
But really must try a new known good screen first, as this is still the first suspect.

Sounds like a faulty digitizer to me, or a poorly seated digitizer connector. Did you do the screen repair yourself, or did you have a repair shop do it?

You should tell your shop about it. If a different "known good screen" does the same (a whole batch can be bad), then the issue can be with a chip on the board that controls touch.

Usually, the problem occurs after a screen has been replaced and the digitizer cable has not been seated properly. You have to ensure the correct sized screws fitted into the correct position. There are four screws holding down the shield that covers the display cables and if you mix them up then your shield and cover will not fit correctly and the cable connectors will move and cause digitizer and screen faults. Uisung #000 screwdriver you can easily remove and refit these screws, if you are unsure the bottom two are the smallest (1.3 mm screws) and then the upper left is slightly larger (1.7 mm screw) and the far right screw is the largest of them all (3.25 mm screw). You can prior to the removal use a coloured marker or pen and colour code the screws to the position they belong to, remember the two lowest screws (1.3 mm screws) are the same size so can be coloured the same. This should help resolve any problems with exchanged screens and cabling to screen faults. Thanks guys
