This could be caused by an improper installation or a partially defective replacement screen. If you installed the replacement screen yourself, take a look at this [guide|67489|guide] and double check your work. If it is properly installed, you could try your original screen to see if it has the same issue or not. If the problem only occurs on the replacement screen, contact your vendor/supplier. If the phone was repaired in a shop, go back to see them and they will resolve the problem.
