The LCD screen on my iPhone was still connected to the body of my iPhone 5 but unfortunately after it drops the LCD screen falls off completely, is it possible that the screen can still be removed without the LCD screen attached
An iPhone 5 screen assembly is composed of many layers, all fused (glued) together to make a single assembly. In some cases, the LCD can delaminate from the rest of the assembly. You will have to replace the entire screen assembly; you can follow this guide.
