Hello. I have Galaxy s4 (GT-I9500) with bad responsive digitizer. The digitizer dont have any cracks. Here is link for youtube video that i do. Video So What is the problem? Is it digitizer problem or motherboard?
Best way to check, Hold your finger on an app. Drag it across all areas of the screen. If the app drops then it’s likely to be the screen. Personally i would reset the phone and see if that fixes it as it may be software.
