The issue of not having touch functionality or partial touch after dropping a phone was a common issue but it could be fixed by replacing the screen and lcd screen assembly. NOT ANY MORE!

iPhone X and newer models are designed as two separate layers of boards soldered on top of each other which we call the a “sandwich board”. When an iPhone is dropped or in some cases ran over by a car, the impact will cause a crack in the solder joints and in some case will break off pads with it.
