i changed led driver ic and coil before. it was okay, the phone worked fine.

then i restore it with latest iOS (before it was iOS 11.0.1) and the touch screen function is gone.

i replaced same screens, but nothing changed, is restore 2-3 times, but same problem.

if touch not work personally i would check touch ic carefully with rehot for to test it, if improves functionality then I would proceed with reballing.
