Touch is not working

@baljotkailay you are not giving us a lot of information. Here are the basics. The touch screen and the LCD are fused on this model. To fix the touch, you will need to replace the display assembly. Of course, while you take it apart, make sure that all the flex cables are properly seated and that the connectors and flex cables are not torn or have corrosion/debris on it. Use something like this video tpo repair your assembly. While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
