I had this problem with a phone I was repairing, an iPhone 5 32Gb in Black (iPhone #1).. it got smashed so I had to replace the screen. The screen was cracked, but the LCD was still working just fine as well as the digitizer. Regardless, I needed to replace it, so I went ahead and removed a good working screen from a device I had stored here for parts (iPhone #2).. when I opened up the phone from where I was going to remove the screen, iPhone #2, I noticed that this screen was not an Apple part, and that somewhere down the line it had been replaced by the previous owner. I tested it and it worked fine on iPhone #2, and it wasn't cracked, so I went ahead and removed it to install it on the device in question (iPhone #1).. however, when I went ahead and installed it on iPhone #1, I noticed the screen was not responding to touch adequately, it was also doing stuff on its own, opening apps clicking the keyboard and so on... so I started to freak out cause I had this happen before with a 5C and I had to end up...
