My smartphone is my exact Galaxy S4 me several times now fallen off the screen is cracked, so far so good but now after the final fall of the permanent phone after the turn black. Does that grants the also the LCD Trallala and / or are damaged touchscreen?
The best answer
So if the screen remains black after the turn, then I would assume that the display is broken and not just the touchscreen. It is also possible that something on the circuit board is broken and the screen therefore receives no information and no electricity. You can add a display and touchscreen exchange and hope that it works again.
